These are milestones marking the large repair capacity of fighter jets and recognizing the outstanding development of Vietnam’s aviation engineering industry. Su-27 fighter at A32 Factory. In addition, the factory also repaired tens of thousands of spare parts and equipment for the units; produce hundreds of thousands of aviation technical materials. Besides, it also repairs special motorcycles; participate in the repair of weapons of the Air Defense units, Navy. Recently, the High-Tech Center went into operation, marking a great step forward of the unit. From here, A32 Factory can improve repair capacity to regional and international level. The People’s Army newspaper also said that in the past time, the A32 Factory has successfully repaired and put into flight 30 aircraft of all kinds, ensuring good technical indicators and handed over to the units. The factory also replaced 4 oil barrels and repaired and enhanced the Su-30MK2 aircraft fuel system; manufactures 188 fuel pipes, special high-pressure gas pipes, special air defense lights for TZM cars… In addition, A32 also repairs and replaces parts and components for air defense units; repair the hydraulic system that controls the rotation of the radar antenna on the ship; manufacturing and mechanical processing of components for the X51 Factory and the General Department of Defense Industry. To meet the requirements and tasks of aeronautical engineering repair, the factory has promoted the spirit of self-reliance, self-reliance, collective intelligence, designed hundreds of mechanical drawings for processing and manufacturing. components, spare parts, technical materials for repair and production. Not only that, but the factory also compiled many documents, including bilingual documents, especially the set of major repair technology, increasing the service life of Su-22 and Su-27 aircraft. Vietnam’s success has surprised the Russian side, in a recent article titled “Su 27/30: Vietnam will repair itself at home”, Russian defense magazine VPK said that Vietnam has self- Repairing and upgrading Su-27 and Su-30 fighters at the new factory in Da Nang. Accordingly, Vietnam is building capacity for basic maintenance and repair of Su-27 and Su-30 fighters, to avoid sending aircraft abroad. To implement this program, Vietnam recently put into operation the A32 defense plant in Da Nang. “The self-repair and upgrade of the aircraft in the country will significantly increase the operational readiness of the fighter,” the source confirmed. According to VPK, to get this result, A32 Factory sent dozens of staff to train abroad. Currently, the factory has successfully repaired the failures of this modern fighter on its own. Each workshop repairs a technical array with over 10,000 different components that require extreme caution, precision, and meticulousness.

Why are airplane windows oval? In the early 1950s, the world’s first commercial jet was developed and manufactured by De Havilland. This is considered the miracle of the aviation industry. However, after a year of use, the plane fell to pieces right in the sky and within a few months, two more suffered the same fate. Engineers scrutinized the plane’s screws and discovered that the main cause was the square window. With this design, the pressure is higher at the door corners and increases significantly in flight. So the engineers decided to replace it with round or oval windows. Why do airplanes have curved wing tips? During a flight, the pressure on top of the wing is lower than the pressure under the wing. Air tends to shift from high pressure below the wing to low pressure above and around the wing tips. In the past, the wing tips were designed to be straight, causing the airflow to cause serious turbulence. Therefore, the scientists decided to bend the wing tip upwards to reduce turbulence, prolong the durability of the wing and save a lot of fuel during travel. Thanks to this feature, everyone will feel more comfortable during the flight. Why do airplane noses have different shapes? The nose of a military aircraft is pointed, the sharper the nose, the faster it flies. However, if the nose is too long, the pilot cannot see the runway correctly, which is why civil aircraft have round noses. Russian engineers solved this problem in the 1960s. The fastest passenger jet could tilt its nose. During takeoff and landing, the aircraft tilts its nose down and during flight the nose will be brought back to its original position. This strange design is intended to help pilots see the runway better. Why are airplanes painted white? Airplanes are almost always painted white. There are several reasons to explain this problem: Heat Reflection: A plane painted white will accumulate less heat. This is better for passengers and economically beneficial for airlines.
White paint is cheaper than other paints.
Prevent bird collisions: Birds can see reflections from white surfaces better, reducing the risk of collisions with aircraft.
White paint helps reveal small cracks and dents: The paint makes cracks easier to see, identifies problems early, avoids accidents, and makes damage easier to see. Why is the exit on the left? Not all but most aircraft have the main entrance on the left side. There is an explanation: The right side is for luggage (the cargo hatch is also on the right) so it is not safe for passengers.
Some say it’s an old tradition: The train ramp is always on the left.
The aircraft door is installed on the left side, which allows them to park the plane in the passenger area better and move more easily. Why are some planes oddly shaped? You must have heard of stealth aircraft. It has an odd shape to avoid detection by radar, sonar, infrared and other detection means, and to be able to carry more luggage with less fuel consumption. The shape of the plane is inspired by birds. Birds of prey use that shape to increase their range and be less visible. However, these aircraft are often too expensive to be used in civil aviation. How do airplanes look spacious? The designers use a number of tricks to make the plane look taller and more spacious than it actually is. For example, the walls have certain shapes to reflect light correctly. The illumination between the ceiling and the overhead bin makes the ceiling visually taller. Thanks to these tips, people with plane phobia will feel more comfortable. Why don’t pilots have beards? Some airlines ban pilots from growing beards. This is explained that, the beard can cause the oxygen mask to not fit tightly to the pilot’s face and work properly in an emergency situation. In particular, in that case, the pilots must always be alert to save the lives of passengers on the plane.

Here is a compilation of a few “evidence” that is said to strengthen the belief of those who are passionate about the existence of UFOs and aliens: Unexplained stories about UFOs 1. Captain William Schaffner Incident, North Sea On September 9, 1970, Royal Air Force pilot William Schaffner was flying over the North Sea when he spotted a strange object in front of his plane, hovering over the water in the North Sea. He decided to investigate, but a few minutes later radio contact with Captain Schaffner’s plane was lost. Schaffner’s plane was later found on the seabed. However, the dome was closed and there was no trace of the pilot. No one knows what might have happened to the captain. (Photo: Marca) 2. The incident Tehran, Iran On September 19, 1976, Iranian military forces detected an unidentified flying object in the sky over the capital Tehran. When two Iranian air force jets approached the mysterious object, the pilots lost radio contact with the ground. When preparing to fire at the UFO, their weapon system also failed. Only after leaving the vicinity of the strange ship did they resume full control of their aircraft. 3. The Lights of Rendlesham Forest, England The Rendlesham Forest Incident is the name given to a series of scenes that occurred in 1980 following an alleged landing of an unidentified flying object in Rendlesham Forest. The British Ministry of Defense has never considered this event a threat to national security. Therefore, the incident was never formally investigated. 4. US Navy encounters UFOs The encounter occurred during a combat exercise conducted in the Pacific Ocean off the southern coast of California on November 14, 2004. (Photo: History) Pilots of six F/A-18 Super Hornets reported detecting “something” in mid-air, and on radars of US Navy ships and other fighters in the area also appeared. this flying object”. In 2014-2015, fighter pilots of the USS Theodore Roosevelt aircraft carrier strike force also reported recording sensors that detected unidentified aerial objects. Amazing images of UFOs In 2016, the US Intelligence Agency (CIA) released a number of photos of mysterious flying saucers that had appeared in the past that the agency had never made public before. The UFO photo was recorded by Stock in 1952 in New Jersey, USA. At about 4:30 p.m. on July 29, 1952, Mr. Stock was sitting in his yard with a friend when they saw a strange object appear in the sky. He ran into the house to get a camera and took 5 pictures of this UFO. The mysterious object flew at an altitude of about 60m, then accelerated and disappeared. The flying saucer was then described as possibly made of metal, solid and had a transparent dome-shaped upper part. Stock and friends say that the disc is blue or blue, makes no noise and is about 10 meters wide. The image was taken on October 20, 1960 in Minneapolis, Minnesota, USA Another image released by the CIA is a strange, large, glowing disc, believed to have been taken on October 20, 1960 in Minneapolis, Minnesota, USA. This image has never been confirmed to contain any content, but it is believed to be one of the first examples of so-called “stealth UFOs”, the term referring to flying saucers hiding in the clouds to avoid was discovered. Pentagon admits UFOs In May 2019, the Pentagon admitted it was investigating UFOs after naval pilots claimed to have recorded UFOs during training exercises in 2004 and 2015. The program to investigate and study threats from unidentified flying objects (UFOs) took place from 2008 to 2011 and cost up to 22 million USD of the US Department of Defense. This is the first time the Pentagon has acknowledged the existence of this program. (Photo: Defense) In 2020, the Pentagon officially released three short videos showing UFOs, previously released by a private company. The footage, titled “FLIR1”, “GIMBAL” and “GOFAST” was captured by a camera on a US military jet. The videos show what looks like an unidentified flying object moving very fast under the infrared camera. Two of the videos feature officers marveling at the speed of the unidentified flying object. One of them speculated that the object could be a drone. NASA discovers thousands of exoplanets NASA has confirmed the number of extrasolar planets (exoplanets) in the thousands, and we can expect that number to continue to grow as we improve the technology that spaceflight can travel. into other regions of space. (Photo: Insider) This opens up the meaning: There are thousands of known planets that have not been discovered for a long time; and several other planets waiting to be discovered that could be in potentially habitable environments. Existence of the Search Institute for Extraterrestrial Intelligence (SETI) The Search for Extraterrestrial Intelligence (SETI) Institute was founded by Carl Sagan and Jill Tarter, two American astronomers who believe there is more interplanetary life than we thought. (Photo: SETI Institute) SETI’s mission is to “discover, understand and explain the origin and nature of life in the universe, the evolution of intelligence.” The institute’s brilliant minds are working day and night to find ways to trace it. life and aliens in outer space. Another scientific organization searching for intelligent life in the universe actually exists on Earth. It’s proof of how seriously humans care about “aliens”.

In the current payroll of the Russian Aerospace Forces, there are more than 2000 jet aircraft of all types. However, this force only uses two-engine fighters, does not own any single-engine fighters. One of the main reasons is that most of the fighters in the current Russian Aerospace Forces, most of which are fighters developed from the previous Su-27 series, use two jet engine. However, part of the reason why Russia did not use single-engine fighters in service, came from the lack of it in the final stage when the Soviet Union was about to disintegrate. Specifically with the MiG-29 fighter. This type of fighter, when developed, was aimed at a single-engine fighter design, to compete with the US-made F-16 fighter. However, this design encountered a very difficult obstacle, that is, the Soviet Union at that time did not have a jet engine strong and light enough to be applied to the design of the MiG-29 at that time. . Designer Mikoyan then had to revise the drawings of the MiG-29, forcing it to use two jet engines instead of one as originally envisioned. Basically, at the last stage when the Soviet Union was about to disintegrate, it was very difficult to spend money on research and manufacturing of new generation jet engines. The fighter designers were then forced to use all that was available to them, and the idea of ​​a single-engined Moscow fighter jet ended since. However, it can still be considered that twin-engine fighters have more advantages than single-engine fighters. The US itself at the present time has also stopped producing single-engine fighter aircraft, the F-16 version, although very popular, has only received further upgrades so far, the new production line has been closed. Doors from 2017 to 2019 are allowed to reopen, but only for export. Compared with single-engine fighters, dual-engine combat is considered to be more stable in operation. In the event of one engine failure, at least one remaining engine is enough to bring the plane to a safe landing. Two engines, which means that the aircraft will have two independent power supplies to power the computer system, and also the hydraulic systems on the plane. With single-engine fighters, once the engine stops working, the aircraft will immediately fall into a state of loss of control. Especially with today’s modern aircraft, which use fly-by-wire electronic steering, as soon as the engine is turned off, the computer will also turn off and the steering system will be useless immediately. The American F-16 fighter itself also uses special fuel, along with an electrical energy storage system, allowing the aircraft to operate for an additional 10 minutes after the engine is turned off. At the end of 10 minutes, the energy reserves will run out and the aircraft will also be uncontrollable. In the opposite direction, a single-engine fighter has the advantage of being more compact, lighter, and more fuel-efficient when compared to a twin-engine fighter with the same output thrust. Even the US F-16 fighters, capable of carrying weapons up to 7.7 tons, are only 300 kg inferior to the Russian twin-engine Su-30 aircraft. In the future, Russia is looking to replace its MiG-29 fighters with a single-engine fighter. However, up to now, the design of the new Russian single-engine fighter is likely still on paper. The first thing Moscow needed was a jet engine powerful enough to carry the fighter. Image source: Pinterest. Russia’s MiG-29 fighter is still considered the most “light” fighter that Moscow owns.

Taiwan Air Force F-16. The Taiwanese military has announced plans to sell its old F-16 radars after Taipei’s fighter squadron received new radar systems. Taiwan’s F-16 fighter aircraft is being upgraded with the new AN / APG-83 AESA radar as part of the retrofitting of the F-16 Block 70 version. However, the old APG-66 radars are still serviceable and valuable in the international arms market, Liberty Times reported. A source familiar with the matter has pointed out that APG-66 radars could also be installed on F-16A / B fighter jets, which are still in service with foreign air forces. After Taiwan completes the retrofit of its jets, a batch of more than 100 APG-66 radars will be sold in accordance with US regulations, with profits transferred to Taipei’s treasury. The value of the old radars has yet to be determined, the source said. Taiwan purchased 150 F-16 fighters from the US in 1992 and received them in 1997. According to the Northrup Grumman group, the new AN / APG-83 features high-resolution synthetic aperture radar mapping in all weather conditions to show pilots a large surface image for item identification. target and more accurate attack information.

Malaysia is currently considering purchasing a new type of light single-engine fighter jet to modernize its air force, with the top three candidates being the South Korean F / A-50, the JF-17. of Sino-Pakistan and Tejas of India. According to some sources, the country’s armed forces are now leaning in favor of the JF-17, a significantly longer operational aircraft that has been produced in larger numbers and deployed. operated by three countries including Pakistan, Myanmar and Nigeria. The F / A-50 fighter is also considered a prime candidate, but the Tejas fighter is not. Other contenders believed to have been eliminated were the Yak-130 of Russia, the British Hawk and the US-Swedish Gripen. The Yak-130 and Hawk had much more limited combat capabilities and were unable to fly hypersonic, while the Gripen had limited features in use. The JF-17 and Tejas have long been regarded as rival fighter jet programs, both of which have many similarities including being very light in weight, and they are smaller than class fighters. Light standard as F-16 and J-10 in size. Both are designed to favor low operating costs and use derivative engines, the engine developed for the Cold War medium-weight two-engine fighters, but used in one engine configuration. Tejas engine was derived from the American F-18, while the JF-17 used engines from the Soviet MiG-29, a direct competitor of the US F-18 during the Cold War. . Both fighters are designed to serve the primary goal of air combat and are built to operate at low cost with either minimal fuel consumption or maintenance requirements. It can be speculated that the reason why Malaysia prefers Pakistan’s JF-17. This fighter was produced in larger numbers and had less difficulty in development than during the Tejas development. Indian fighters entered service more than 40 years after development began. The JF-17 is also available in many variants including a two-seat attack and training variant like the JF-17B. Sino-Pakistani jets are also more compatible with modern armament to which Malaysia is currently heavily dependent, while the Tejas is a Westernized aircraft. Tejas uses American engines, especially Israel’s avionics systems, which is a big drawback for an Islamic country like Malaysia – which doesn’t like Israelis. Tejas is also significantly more costly to manufacture due to the less efficient production line and the very high cost of the component parts from the US and Israel on which it depends. The latest Tejas variants especially have a superior radar advantage over the JF-17 Block 2. However the upcoming JF-17 Block 3 variant is expected to go into mass production by the end of 2023 and will be available. the performance is far superior. Among the outstanding features of the JF-17 Block 3, the most prominent are the integration of AESA radar, Chinese PL-15 air-to-air missile, improved engines and generation avionics. Thursday. In the end, no matter what type of fighter aircraft is chosen, the new aircraft will be a secondary force, while the elite Malaysian air force still consists of Russian Su-30MKA heavy fighters. In addition, the country is particularly interested in more modern Su-57 next-generation fighters. Photo source: Pinterest.

Mattala Rajapaksa International Airport is located in Mattala town, Hambantota district (Sri Lanka), considered the quietest airport in the world. According to Forbes, almost no passengers arrive at this airport for travel purposes, because the number of operated flights is too low. Photo: Forbes. Most of the visitors to the airport are visitors from nearby wildlife parks. They were curious to see what the world’s quietest airport would look like. The airport was named after the then President of Sri Lanka (Mahinda Rajapaksa) and was opened in 2013. Photo: Wade Shepard. The airport is located in a forested area 250 km from the capital Colombo. The 12,000-square-meter terminal includes 12 check-in counters, two gates, a 3500 m long runway capable of receiving the largest line of commercial jets with a capacity of one million passengers per year. However, during more than 7 years of operation, the airport is extremely deserted despite its close proximity to famous tourist destinations such as Arugam Bay and Yala National Park. Photo: Forbes. There are very few aircraft anchored at this airport. “There are very few other sounds, no flight announcements through the speakers, no scenes of crowded passengers or the sight of a taxi driver trying to solicit passengers. The corridors are empty, no one. Except for me, “said Forbes reporter Wade Shepard. Photo: Wade Shepard. In fact, MRIA airport still has full services such as information kiosks and support staff, cleaning workers, souvenir stalls, coffee shops and security guards. Full service and only no passengers to service. Photo: Wade Shepard. The airport is part of the plan to create Hambantota to become the second largest city in Sri Lanka, attracting foreign investment and becoming a destination for international trade and transactions. In addition to the airport, Sri Lanka also built a huge deep-water port costing more than $ 1.4 billion, an industrial park, a convention center, a stature cricket stadium, and resort hotel. and a modern highway system. Photo: Wade Shepard. However, many experts assess Mattala town is not an ideal area for urban development. This is just a small fishing village, surrounded by jungle. In 2020, MRIA’s total passenger capacity is only about 20,610 seats, much lower than other airports in the world. In 2019, the airport’s passenger capacity is only about 19,600 people. On average, the airport serves only 55 passengers a day. There are times a day the airport only serves 10-20 passengers. Photo: Wade Shepard. The road leading to the airport is also deserted, with no traffic or tourists. The national airline of Sri Lanka has stopped operating the route here. The airport reported a loss of about 18 million USD / year. To finance the construction of mega-projects, Sri Lanka borrowed at least US $ 4.8 billion from China. Mattala Rajapaksa Airport alone has been invested hundreds of millions of dollars. Photo: Wade Shepard. The government is using the airport for a number of other purposes such as renting warehouses and stations to store rice, and runways with long-term parking. The government also mobilized up to 300 soldiers and police to prevent wildlife from appearing on the runway. Staff were also cut. Airport management said that initially there were 600 employees, then cut it down to 300, or even lower. Photo: Wade Shepard.

According to Defense World, the US Air Force recently announced blueprints for a new fighter jet being developed under the “Next Generation Aviation Advantage” (NGAD) program, which includes including unmanned and manned fighters.

The image shows a triangular flying fighter and its aerial weapons on display as well. The configuration of this fighter is also very different from today’s fighters, the plane is relatively flat, triangular seen from above, has a pair of vertical V-shaped tails and the air intakes located above. fuselage.

The photo shows that this fighter jet has very highly modular characteristics, can quickly replace engines, landing frames … thereby reducing the load of logistics maintenance, missile pods inside. The aircraft is also equipped with a variety of missiles.

The NGAD program was originally proposed as a joint project of the US Air Force and Navy. Although there is still some joint cooperation between the two sides, each side has in turn set up independent offices to research and develop next-generation fighters.

From 2019 to 2025, the budget for the NGAD program of the US Air Force is 9 billion USD, of which the budget for the fiscal year 2021 is 1 billion USD and the budget of the fiscal year 2022 is 1.5 billion USD.

According to the report, the NGAD program aims to complement the F-22 and F-35 fighters, creating a system with multi-domain cognitive capabilities, flexible information and strong operational advantages. air raid attack. The program will apply digital technology to large-scale fabrication and replacement of small components.

This approach is based on the automotive industry’s digital transformation and uses models to solve design, assembly, maintenance and repair issues before, the Air Force said. build a physical system.

The US Air Force report did not specify the cost of the project to build the aircraft. However, the report mentions that a mysterious jet under the project was tested in 2020, and it is still unclear whether the plane is manned or not.

“We have built and tested a new aircraft and broke all aircraft records,” said Will Roper, Assistant Secretary of the Air Force for US logistics and technology equipment procurement. fight. We are now ready to build the next generation aircraft in an unprecedented way. “

Some previous reports suggested that the NGAD program plane will have an artificial intelligence co-pilot, maybe even the ARTU system (artificial intelligence system built by algorithm to play chess. ).

The artificial intelligence system will act as a support for true pilots, but the weakness of AI systems lies in their logic, while actual military actions may not obey this logic. Human presence is then required to make a decision in unusual, non-standard situations.

It is known that from March 2018, the US Air Force Laboratory has released the image of the next generation F / X aircraft, showing that this aircraft will have a stealth design, eye-catching appearance with laser. High energy capable of cutting enemy aircraft in half.

This is also the main aircraft in the NGAD program, also known as the Penetration Jet. The future F / X aircraft is expected to have longer range and payload, as well as the ability to carry hypersonic weapons.

Under the NGAD program, the US Air Force advocates to exploit advanced capabilities of the new generation of aircraft such as air combat systems linked to fighters, drones and networking platforms. . With the aim of increasing air superiority, the F / X fighter program offers significantly enhanced stealth and works closely in coordination with the drone.

Until now, all information about the capabilities of the F / X is still a military secret. If the program progresses at a rapid rate through streamlined processes and uses current technology, the new generation fighter could join the US Air Force earlier than expected in 2030. .
