China’s passenger jet C919 is lagging behind schedule

Status: 19.06.2021 07:29 a.m.

China’s domestic C919 passenger aircraft is set to compete with Airbus and Boeing. But the approval is still missing – and there is still no date for the first delivery.

From Steffen Wurzel, ARD studio Shanghai

China’s government has invested billions in developing and building its own passenger aircraft in recent years. There are great hopes for the C919. This medium-haul aircraft from the state manufacturer Comac should be able to carry up to 190 passengers in the future. In terms of size and equipment, the C919 is comparable to the Airbus A320 and Boeing 737. “Technically, the C919 is actually an international aircraft,” says David Yu, aviation analyst and economics professor at Shanghai’s New York University. Many individual parts of the machine come from the USA and Europe. “It will be assembled in Shanghai. Yes, the C919 is a Chinese aircraft, but with a significant proportion of foreign components,” says Yu.

Approval in China possible this year

Their Maiden flight had the C919 four years ago. It is still unclear when the machine will be delivered. The project is several years behind schedule, which is normal for all manufacturers around the world when they develop new aircraft models.

So far, the C919 does not even have official approval from the Chinese Civil Aviation Authority (CAAC). If this approval is granted – and that could happen this year – the machine will probably only fly in China for the time being. It is still unclear whether the responsible aviation authorities in Europe (EASA) and the USA (FAA) will also approve the machine.

In 2017 the C919 took off on its maiden flight – the start of delivery is currently still open. Image: picture alliance / Andy Wong / AP / dpa

For the time being, probably only in Germany

Nevertheless: Even if the Chinese medium-haul jet is initially only allowed to fly on domestic routes in the People’s Republic, Airbus and Boeing will not be left without a trace, says aviation analyst Yu. “Asia and especially China are the largest growth markets for the aircraft industry. If you also look at who ordered the aircraft – especially Chinese airlines and leasing companies – it becomes clear that the C919 will take Airbus and Boeing’s market share in China reduce, “said Yu. In China, all airlines and even leasing companies belong to the state – or they are subject to the instructions of the communist leadership. Ultimately, this can decide which aircraft type is bought by whom. This is also a clear advantage for the state-owned Chinese manufacturer Comac

According to Business Insider, a video clip recently released by Gravity Industries (UK) shows soldiers of the Royal Marines wearing a Jet Suit personal jet produced by this company. disembarking from the speedboat, ascending, and rapidly landing on the deck of the Royal Navy’s offshore patrol vessel HMS Tamar. In the video, British soldiers fly easily over the sea like the superhero character Iron Man (Iron Man) in the famous Hollywood movie of the same name. The Jet Suit personal jet suit helps the wearer move easily through the air. Photo: CNN The exercise was conducted to explore how to land on ships as an alternative to the traditional method. In a statement, the Royal Navy said the Royal Marines used the Jet Suit to practice the “visit, board, search and capture” (VBSS) operation. VBSS is considered one of the most complex and dangerous sea missions. Traditionally, soldiers would use speedboats to approach warships and use rope ladders to climb or conduct landings from helicopters with the support of snipers and drones. Both of these methods require a lot of time to prepare the means. Meanwhile, with a personal jet suit, a soldier can fly up from a speedboat, land on a ship and then release a rope ladder for teammates to climb onto the ship. The images in the video clip show the Jet Suit’s ability to support soldiers on landing missions on board ships. “The Jet Suit provides extremely rapid access to any area of ​​the target ship, making it convenient for soldiers to carry weapons and easily move or retreat,” said Gravity Industries. . This is a tactical revolution for many special forces and can be applied more widely than just landing on ships.” With an operation time of 8 minutes, the Jet Suit personal jet made by Gravity Industries is equipped with 5 mini jet engines, including 4 engines attached to the arms and one on the back. Thanks to this design, the user can easily adjust the flight direction as desired. After wearing the Jet Suit, the user can fly at speeds up to 88km/h. This technology is a big step forward in making scenes from sci-fi movies come to life. British inventor Richard Browning, founder of Gravity Industries and a former member of the British Royal Marines, has worn Jet Suits to show the world many times and has been dubbed “Real-life Iron Man real”. Commenting on the Moskovsky Komsomolets newspaper, Russian military expert Vladimir Gundarov said that, like the supporting skeleton or invisibility cloak, personal jet suits will not be widely used in military units. . “All special equipment will be provided to the special forces and can be used in an emergency,” said Vladimir Gundarov. Besides the obvious advantages, Boris Gundarov said that personal jet suits also have disadvantages such as the lack of stealth, jet engines emitting a lot of noise and emitting a lot of heat. A person flying in the air with a personal jet suit is an easy target for any weapon, the expert notes. It is not clear how effective the Jet Suit will be if used on the battlefield, but it is clear that this personal jet suit will need to be improved to overcome some disadvantages that can endanger soldiers. as well as extending the operation time to match combat operations.

From the taste to the aroma of this dish, everyone is impressed. The broth has a sweet taste from the bones, “as a background” for the extremely characteristic salty taste of fish sauce. But thanks to the roast pork, fresh and greasy seafood, the vermicelli bowl is able to harmonize the flavor. The delicious Western noodle soup is when eaten with dandelion, water spinach, water lily. Thanks to the crispness and freshness of vegetables, the dish is easier to eat but does not make the broth thin or pale.

(Photo: Internet) Da Nang seasoned vermicelli with fish sauce The dish is dry mixed, so you will feel the original flavor of the seasoning sauce mixed in each ingredient. Although a bit apprehensive at first, but when enjoying, that hesitation will give way to the salty taste of fish sauce, the fat of pork rolls and ears, a little bit of roasted peanuts and the sweetness of cucumber, raw price . Bun mam seasoning is easier to eat because the amount of fish sauce is relatively small, only faintly in the throat. The combination of boiled meat, pork ears, beef rolls… has made the bowl of vermicelli more diverse and colorful. Photo: Internet Da Nang seasoned vermicelli noodles are unique in the passionate aroma of Central Vietnam’s fish sauce. (Photo: Internet) Durian dishes sầu This list cannot be complete without durian. The tropical fruit has a passionate scent and a thick consistency that no other dish has. For the sweet team, this is a “extreme product”. Not only eaten as a common fruit, durian has countless variations, combined with other ingredients to create excellent snacks. This is durian tea, durian dumplings, fried durian, durian cheesecake… A whole culinary paradise like this is enough to prove how “heavy” durian makes diners. Photo: Internet Durian with countless variations, combined to form dishes “thousands of people love”. (Photo: Internet) Noodles with bean paste with shrimp paste Although “originating” from the North, in terms of popularity, vermicelli with shrimp paste can stand on par with Southern noodle dishes. Because when eaten with vermicelli or other dishes, shrimp paste still brings a unique flavor that is hard to resist. The bowl of shrimp paste must be mixed with sugar and kumquat (kumquat), cut a few slices of chili to have all the stimulating flavors of sour – spicy – salty – sweet. Flexible vermicelli, boiled pork leg meat that is both soft and fatty, hot fried beans… any ingredient when combined with a cup of fragrant fish sauce becomes twice as attractive. Photo: Internet It’s so attractive, but not everyone has the “courage” to try this dipping sauce for the first time. Instead, some people will use it with sweet and sour sauce. That’s why it is said that this is a dish that can divide the world into two factions. But once you have enjoyed the unique taste of shrimp paste, you will find that the sweet and sour fish sauce vermicelli is somewhat less delicious. The smell of shrimp paste is strong and strong, so many Saigon people feel shy when enjoying it. (Photo: Internet)

TS. Alexandre Yersin born in 1863 in the State of Vaud, Switzerland. At the age of 20, he studied medicine in Lausanne (Switzerland), then continued to study in Marbourg (Germany) and graduated from the University of Paris (France) with a doctorate in medicine. Since 1886, Yersin worked at the Pasteur Institute and collaborated with Dr. Roux to find out the toxin of the diphtheria bacteria. In 1889, Yersin naturalized French. Yersin- the world-famous doctor thanks to the discovery of bacteria that cause plague. A bright future is opening up Young Yersin . However, in addition to his passion for medicine, Yersin has a desire to explore nature. To fulfill his dream of exploring strange lands, he would like to be a doctor on a transport ship floating at sea. In 1892, he went to Nha Trang, Vietnam. The tropical climate is full of mysteries and attractions that make the decision to live, work and stick with this land. Here, he made expeditions to discover new lands. Thanks to these trips, Yersin found Lang Biang Plateau. That was January 1893, he made an expedition that lasted for nearly 7 months. After crossing the rugged mountains and ethnic minority villages, in June 1893 Yersin discovered Lam Vien Plateau (Lang Biang Plateau), 1,500 meters high, today Da Lat city. Yersin wrote in his notebook: “The impression is so profound. Out of the pine forest, I saw right in front of the vast, bare plateau, like the sea was rolling in green waves. The Lam Mountains. Vien with 3 peaks of 2,000 meters, rising from the northwest horizon, creates a majestic backdrop that enhances the magnificence of this region “. In 1897, it was he who proposed to the Governor-General of Indochina, Paul Dumer, to choose this place as the site for the construction of the sanatorium. Then, by a trip to the plateau with the Governor-General of Indochina, he took part in deciding to establish a nursing station on Lang Biang Plateau – the forerunner of Da Lat city later. The first person to find the bacteria that cause the plague In 1894, while preparing to make the next expedition, at the request of the French Government and the Pasteur Institute, Yersin traveled to Hong Kong to study the plague. Here he saw dead bodies of plague dead in the streets, among puddles, in gardens, on moored boats. Yersin has spent most of his life in Vietnam. When Yersin discovered that his colleagues were looking for the plague bacteria in the blood, Yersin said that this is not the right way. According to Yersin, the bacteria must be found in the lymph nodes. With the help of Vigano, an Italian living in Hong Kong, Yersin works in a straw-covered bamboo shack. In order to get the corpses for experimentation, he had to pay money to British sailors who were supposed to bury the bodies. Thanks to that, Yersin was able to enter the body cellar several hours before the body was taken to the cemetery. He had to remove the lime coating the corpse, cut the lymph nodes himself from the corpse and bring it to his laboratory. The microscope shows a multitude of homogeneous images of stick-shaped, two-headed, stick-shaped bacteria. Yersin injected the bacteria into the mouse, twenty-four hours after the mouse died. Other test animals die from two to six days and in cadavers full of lymph nodes. Over a period of seven days, Yersin found the plague bacteria. He sent to the Pasteur Paris Institute a number of fully filled test tubes taken from the sick lymph nodes. When the plague in Hong Kong has calmed down, Yersin returned to France to work with colleagues on the vaccine to prevent it, and the sera (sérum) to treat the plague. When the serum production was completed, Yersin asked to return to Nha Trang to set up a laboratory and build a horse farm in Suoi Dau to produce a lot of serum to prevent patients in neighboring countries. In 1975, the Tenth World Congress of Biology decided to name the plague bacterium “Yersinia-Pestis”. Scientists said that Dr. Yersin was the benefactor of humanity when it was able to prevent the plague at that time. Add more imprints In 1902 – 1904, at the request of Governor-General of Indochina Paul Dumer, Yersin went to Hanoi to establish and run the Indochina Medical and Pharmaceutical School in Hanoi – the first medical training facility of the Indochinese peninsula. built according to the model of the West. Besides medicine, Yersin is passionate about exploring new lands During those difficult early years, Yersin worked actively to found the Medical and Pharmaceutical University and became the first principal of the University (a member of Indochina University in 1906, later to become the University of Indochina). Ha Noi medical university). With his contributions and dedication to the field of medicine, in 1904, Yersin was appointed as a representative of Pasteur Paris Institute in Indochina and Director of Pasteur Institute Saigon and Nha Trang. He also holds many important positions in the health sector. Not only contributing in the medical field, he also has many contributions in the agricultural field. He was the first to import rubber trees from Brazil to plant in Vietnam. Not only importing trees, he also pays special attention to the methods of planting, exploiting and processing rubber to have the highest efficiency. He set up an agrochemical laboratory. Here, the methods of breeding, tapping and coagulating rubber have been studied in a systematic way. Thanks to that, rubber growers in Indochina in the past no longer had to struggle as before. Yersin breathed his last in early 1943. According to his wishes, when he was buried, he was placed on his stomach, his head turned to the sea so that he forever embraced his second home land.

Photo of the Ingenuity Mars helicopter taken by NASA’s Preseverance spacecraft. Photo: NASA. Open a new door Ingenuity attached to the belly of the Perseverance probe landed together inside Mars’ 45 km wide Jezero crater on February 18. On April 3, a solar-powered helicopter was dropped from Perseverance’s belly. NASA is expected to make history on the Red Planet with its first self-powered flight powered by energy. “That is extremely important. Technological inventions will open a door to completely different tools. And for me, that’s very interesting. We still haven’t envisioned all the benefits of this new technology, ”said Thomas Zurbuchen, NASA’s Deputy Administrator. Ingenuity is considered a “technology show”. Because, the expected flight of this helicopter on Mars is designed simply to demonstrate the efficiency of the technology. Although there is an onboard camera to take pictures during the mission, it’s the only feature on the plane that is not directly related to Ingenuity’s take-off. “The speed of light is too slow for us to actually control it in real time,” said Mr. Zurbuchen. In addition, the team must find a way for the helicopter to fly over Mars in a challenging environment, with a very thin atmosphere. Obviously, flying on another planet is not easy for helicopters. This is an exciting moment in the history of spacecraft and technology. Many people questioned whether Ingenuity was equipped with any technology application to achieve such a feat. Scientists hope to use Ingenuity to explore in the future, according to Zurbuchen. Because, a small helicopter can “probe many places that we can not go to by plane”. The expert also explains that Mars has some interesting things. The crater walls and other destinations will be interesting to study up close, while astronauts won’t be able to explore. In the future, helicopters could be an important asset for both robot and human exploration on the Red Planet, Mr. Zurbuchen said. However, as mentioned before, Mr. Zurbuchen said, there are many applications to this technology that are yet to be developed. Science breakthrough The deployment of the Ingenuity helicopter flight plan on Mars aims to demonstrate that humans can fly in the extremely low density, reduced gravity and extreme temperatures of the red planet. In addition, the amount of sunlight the planet receives is only half that of Earth; At night temperatures down to -90 degrees C cause electronic components to crack and freeze if left unprotected. While a mission on Mars is not an easy task, NASA is confident that this small helicopter can overcome the challenge. However, the first flight will be at low altitude and take place shortly. Members of the mission group said, Ingenuity (weighing 1.8 kg) is expected to fly no more than 3 meters above the floor of the Jezero crater on Mars. The helicopter will stay high for 40 seconds or so. However, even such a modest flight time would be an achievement. Because, Mars’ atmosphere is only 1% thicker of Earth. Aircraft generate lift by pushing air. However, according to Project Director Ingenuity – MiMi Aung, of the NASA Jet Propulsion Laboratory (JPL) in Southern California, on Mars, there are fewer molecules to propel. That disadvantage outweighs the benefit that helicopters get from Mars’ weaker gravity. So Ingenuity has to behave a little differently from its predecessors on Earth. Specifically, Ingenuity propellers are made of carbon fiber, made for Mars. They are particularly large compared to the overall 48 cm high helicopter. Each wing extends 1.2 m. Those propellers will spin at about 2,500 rpm to bring Ingenuity off the ground. This is much faster than that required by a 4lb motor. Besides, Mars is also a place where the cold is “piercing”. Perseverance measured the Red Planet’s nighttime temperature to minus 117.4 degrees F (minus 83 degrees C) on the surface of Jezero. So Ingenuity has a fireplace so it won’t freeze. Currently, it takes more than 15 minutes for an order to be sent from the control agency on Earth to Mars. Real-time operation with the joystick is therefore not an option. Flight orders must be sent in advance. However, that doesn’t mean Ingenuity is going to be in trouble. This helicopter will be able to do many tasks on its own. For example, Ingenuity can analyze photos captured by the downward-facing camera. From there, locate it. The images will be in black and white. Ingenuity is also capable of 13-megapixel color photography. There are a series of complicated devices that are inserted into the “small body” of Ingenuity, although the helicopter does not carry any scientific tools. Cameras, electrical systems, avionics systems, and communications equipment for data transfer to Perseverance were all introduced into Ingenuity. In fact, the size of devices like objects has made it impossible for many helicopter missions on Mars. Ms. Aung and her colleagues tested Ingenity extensively on Earth before launching. Ingenuity used to have to fly in a special chamber at the JPL – which simulates the conditions of the Red Planet. Thanks to that, Ingenuity has been doing well on the Jezero crater since its separation from Perseverance. Therefore, the scientists expressed confidence in Ingenuity’s mission. If successful, Ingenuity will fly again – up to 5 times in about a month. Ingenuity helicopters pave the way for future space exploration.

Qian was born when the last Chinese dynasty was about to be replaced by a republic. From a young age, Qian was gifted and eventually, he graduated with distinction from Shanghai Jiaotong University, winning a rare scholarship from Massachusetts Institute of Technology (MIT) in America. Qian Xuesen (Precursor of Ginseng) From MIT, Qian moved to the California Institute of Technology (Caltech), studying under one of the most influential Hungarian aeronautical engineers named Theodore von Karman. There Qian shares his office with another famous scientist, Frank Malina, who is a key member of a small group of innovators known as the Suicide Squad. Fraser MacDonald, author of “Escape from Earth: A Secret History of the Space Rocket”, said the group earned the nickname for its efforts. of them in building a rocket on campus and because of some of their experiments with volatile chemicals. At that time, rocket science was considered by MacDonald as “a tool of reelers and fantasies. No one takes it seriously – no mathematic engineer has risked their reputation in saying this is the future. But, that quickly changed when World War 2 began. The “suicide squad” attracted the attention of the US military and was funded for research on a jet-assisted takeoff method, where the boosters were attached to the wings of aircraft so they could fly. overhead from short runways. Military funding also helped establish the Jet Propulsion Laboratory (JPL) in 1943, with its director, Theodore von Karman. Qian, along with Frank Malina, is at the center of the project. Qian is a Chinese citizen but the ROC is an ally of America, so “there is no great doubt that a Chinese scientist is at the heart of America’s space effort,” said Fraser Macdonald. Qian is licensed to work in the classified weapons research department and even served on the US Government Scientific Advisory Board. At the end of the war, Qian was one of the foremost experts in jet engines and was sent with Theodore von Karman on an extraordinary mission to Germany, serving as a temporary lieutenant colonel. Their goal was to interview Nazi engineers, including Wernher von Braun, Germany’s top missile scientist. America wants to find out exactly what the Germans know. But, by the end of the decade, Qian’s sparkling career in America suddenly stopped. In China, Chairman Mao Zedong proclaimed the founding of the People’s Republic of China in 1949. Meanwhile, a new JPL director believed there was a spy group at the laboratory and shared the suspicions. about a number of employees with the FBI. It is in this atmosphere that the FBI accuses Qian, Frank Malina and others of threats to national security. The allegations against Qian are based on 1938 US Communist Party documents that show Qian attended a social gathering that the FBI suspected was a meeting of the Communist Party of Pasadena. Zuoyue Wang, a history professor at California State Polytechnic University, claims there is no evidence that Qian ever spied for China or was an intelligence agent while he lived in the US. However, Qian was stripped of his security passport and placed under house arrest. Caltech colleagues, including Theodore von Karman, wrote to the government pleading for Qian’s innocence but to no avail. In 1955, after Qian was under house arrest for five years, President Eisenhower decided to expel him to China. The scientist left by boat with his wife and two children born in America. Qian told reporters he would never set foot in America again and that he kept his promise. When he arrived in the US, Qian had very little knowledge of rocket science. But, 15 years later, he oversaw the launch of the first Chinese satellite into space. For decades, Qian trained a new generation of scientists, and his work laid the foundation for China to send people to the Moon. While most Americans know nothing about Qian and his role in the US space program, Tianyu Fang said many Chinese Americans and Chinese students in the US knew about him, why he had to leave. and they see similarities today. “US relations with China have become so much worse that they know they could be suspected of being like Qian’s generation,” Fang commented. In Fraser MacDonald’s view, Qian’s story is a warning about what happens when knowledge shredding. “The whole story of American science is that it was driven by people from outside.” MacDonald believes that JPL’s contribution to the American space program was far ignored compared to Wernher von Braun and other German scientists, who were secretly arriving in America shortly after von Karman and Qian’s visit. Braun was once a Nazi but his achievements are recognized. Whereas the achievements of Qian and others from the JPL are not. Qian’s life lasted for nearly a century. During that time, China has grown from an uneconomical country into a superpower on Earth and in space. Qian is part of that transformation. But, Qian’s story can also be a great American one – where talent can flourish wherever talent is found.

New Russian light jet artillery system. (Source: Sputnik) This is information shared by Mr. Alexander Kochkin, CEO of JSC NPK Techmash. “The lightweight MLRS system model was introduced to interested military authorities and received their support in principle. The military proposed a way to install this jet artillery in cars. As well as the missions placed on the system on the battlefield, the key to building this model is the S-8 type unmanned missile, “Kochkin said. He noted that at present, related businesses are actively conducting research work, which defines the technical structure of the new MLRS system, from which it will fabricate and test samples of the system. According to Alexander Kochkin, “the review of the test results, the development of feasible proposals to continue the work and the form of implementation of those options, as well as the funding expected to be completed by 2022” . NPO SPLAV is the developer and manufacturer of all Russian series jet artillery systems – proven MLRS systems such as Grad, Uragan and Smerch, as well as the state-of-the-art Tornado-S and Tornado-G. So far the minimum size of the MLRS system produced in Russia is 122 mm. The S-8 is a Russian unmanned missile with the size of 80 mm. The ammunition is designed to be launched from helicopters and aircraft to strike ground targets. The missile has many different warheads weighing from 3 to 9 kg and can destroy both infantry, armored vehicles as well as entrenched enemy structures. (According to Sputnik)
