I ask you to build tractors, but you build rockets?

"China Eastern Airlines has received the first domestically produced narrow-body large passenger aircraft, the C919, and is expected to begin formal operations next month."

During a break in the Beijing conference, Lin Ju's attention was attracted by the sudden trending search.

Three months after the first flight, COMAC completed the production of the first mass-produced version of the C919 as quickly as possible. This passenger aircraft belonging to China Eastern Airlines was sent by their pilots to conduct a joint test flight at the Shanghai Hongqiao Airport.

If there are no problems after 100 hours of flight testing, it means that it can be officially handed over to airlines to sell tickets and start official operations.

Watching the blue-green painted C919 test-flying in front of the public, Lin Ju couldn't help but think of the C822 and C832.

Interestingly, although the two projects are being carried out at the same time and the C832 is a more technically difficult wide-body mainline passenger aircraft, the C832 has progressed faster so far.

Because C822 Xinyuan's research strength accounts for less of these two projects, C832 basically occupies a dominant position, and key designers and engineers, as well as component manufacturing, tend to be undertaken by the Xinyuan base.

With the participation of the research institute and the An-1250 team, the progress of the C832 is astonishingly fast. As a large passenger aircraft with a take-off mass of 250 tons, the main structural tests and prototype body mechanics tests of the C832 have been completed before the Spring Festival.

The next step is to wait for various manufacturers to rush to produce the parts of the first prototype for test flight, and then transport them for final assembly. After ground inspection, they can be sent to the sky.

Almost all of these manufacturers are involved in the manufacturing of passenger aircraft such as C919 and C822, and they are even part of the supply chains of Boeing and Airbus.

The purpose of the C832 and C822 brothers is different from that of the An-1250. While they solve the demand, more importantly, they are to develop a modern passenger aircraft R\u0026D, production, and assembly industry chain. They need to connect various enterprises, and the progress will inevitably be slowed down.

During the first batch of An-1250 manufacturing, only some "not too high" technical parts were subcontracted. Most of them were manufactured in bases, and the cost was unbearable for passenger aircraft.

Different from C822, the C832 team is very experienced and the subsystem part that Xinyuan is responsible for supplying does not need to be re-researched and tested. The money saved is used to distribute profits to other suppliers, causing domestic supporting companies to also More willing to invest energy in C832.

The C822 is expected to complete its first flight in October, while the C832 is scheduled for May... This is outrageous!

The above people have been paying close attention to the progress of the two aircraft. Naturally, they know that C832 is making rapid progress, which makes them even more happy.

Often when leaders come for inspections, whenever they pass by Shuchuan, they will take a walk to see the C832 project team. Air China is also paying close attention to the C832 airframe design so that it can plan the internal layout of the special aircraft in advance. After all, they don’t have much experience in this area.

In the last century, the country originally bought a Boeing 707 as a special plane. However, when it was dismantled, the cabin was filled with bugs, so it was quickly returned to the civil aviation industry and used for ordinary flights.

Later leaders' trips were temporarily modified from the 747s operating on normal routes. No matter what, it was definitely not as comfortable as the original special design from the beginning. Aramco's Air Force One is also a 747, and its internal functions are comparable to the high-end ones temporarily transferred by Air China. too much.

Xinyuan's R\u0026D personnel silently memorized Air China's various plans, because they may also purchase a C832 as a special aircraft for the base, which may be used.

Lin Ju imagined that he was sitting on his superior's special plane of the same model and interior... Haha.

"Commissioner Lin, Commissioner Lin!"

Wu Wenren's whispered reminder woke him up from his fantasy, and he realized that he had entered the final photo session. He hurriedly straightened his posture and sat down, while whispering his thanks.

Wu Wenren saw Lin Ju distracted by the news about C919, blinked and whispered:

"Commissioner Lin, we are waiting for your C822 and C832. Then you won't have to fly over in a fighter jet."

"Actually, I think it's pretty good. It's much faster than a passenger plane."

"This is against the rules after all..."

Wu Wenren's look made Lin Ju a little embarrassed. Because he had been commuting between the capital and the base for a long time, Lin Ju was also worried about the three-hour flight time. Even if there was a special plane to pick him up from the base, it would be a bit troublesome.

Later, one time he simply sat in the back seat of a GJ-21 "Meteor" high-education aircraft at the base, hung up two auxiliary fuel tanks, flew at supersonic speed for the second half of the journey, and declared military routes, saving an hour and a half.

After that, he discovered the New World. Taking advantage of Xinyuan's close relationship with the Air Force, he modified a high-education aircraft equipped with a conformal fuel tank. It can fly 1,700 kilometers at a speed of Mach 1.5, just enough to fly directly to the capital. Each flight will be The time was compressed to one hour.

Although no one cares about this matter, and the "Meteor" flies at an altitude of more than 18,000 meters and does not affect civil aviation, it still received complaints such as "It is great to have its own aircraft."

This move also spoiled others. Base executives all fly GJ-21 when traveling. After all, it is fast and safe. The ejection seat can save your life at any time, and missiles can be dodged. You can often hear familiar sounds in cities passing through common routes. The roar of the engine...

All of this is seen by many people, and they will definitely not let this happen for a long time. Wu Wenren can see this.

…

"First? Just take it if they want."

At the B-level base, Serev dismissed the news that the Aramco media had hyped BE4 as the world’s first methane-powered engine.

For traditional liquid rocket engines, whether liquid hydrogen, methane or kerosene, Xinyuan has information covering various types and the full thrust range, and can easily design almost any traditional engine.

Now the base's focus is on the A100 and NAPE. They can crush all previous engines into pieces. There is no point in worrying about being first. Nuclear power is epoch-making.

But what makes Serev feel a little bad is that Guo Shen has recently been researching a high-thrust toxic fuel rocket engine!

The classic combination of hydrazine compounds and dinitrogen tetroxide has a thrust ranging from 10 tons to 150 tons. The internal code is "C" series, which means that the fuel is stored at room temperature, and they are all highly toxic and heavily polluting engines.

The C series engines have low specific impulse and high pollution. Naturally, they are not used to build rockets. Their application range is: Venus.

Xiao Gangtian set his sights on Venus after completing the "Lihuo" project, and planned to launch satellite detectors and detectors for detection in Venus' atmosphere as soon as possible.

The satellite detector is named "Taibai" and is based on the same platform as "Lihuo", but for the sake of cost, solar cells were chosen, with a mass of about 7 tons and a solar power panel power of 55KW.

The function of "Taibai" is mainly focused on the atmosphere, magnetic field and geological detection of Venus. The atmosphere of Venus is especially interesting.

As the closest terrestrial star in the solar system, Venus is similar in size and weight to the Earth and has a thick atmosphere. Besides Mars, it is another possible colonization target that has attracted great attention.
