"How's the trial going?"

At the B-level base, Seryov jumped from the hatch of the Tengyun Project No. 001 and asked his assistant about the Qiongzhou sea-launched sounding rocket.

"Very good, the engine line is cleaned with high-pressure steam, and the arrow body is not damaged at all.

Minister Guo asked to renovate the interstage separator to leave more space to come out. ”

Launching rockets in the water is not uncommon, after all, submarine-launched missiles are just that.

The corrosion of the engine and the rocket body by seawater is actually not large, or even negligible, after all, the energy rocket that Baikonur collapsed by snow has not rusted for so many years, and only needs to be slightly improved.

Not to mention the engine, even the strong corrosion of liquid hydrogen and high temperature conditions can resist, which is nothing to seawater.

So there shouldn't be a problem with the experiment, and there should be something that is abnormal.

"Very good, urge the auxiliary system again, prepare the supporting facilities as soon as possible, you must conduct a drill before the official launch, the No. 4 rocket is so expensive, it is troublesome to repair it."

Seryov is still relatively relieved about Xinyuan-4, this super rocket is basically all manufactured by the base, and the design and manufacturing are guaranteed, the only thing to worry about is the transportation and launch system, and other manufacturers are too easy to drop the chain.

For example, the prototype of "Tengyun" 001 conducted its first ground taxi test on the night of September 17, and the problem was immediately discovered.

Fortunately, it was only a small trouble on the pipeline, but Seryov immediately ordered the base and the technical experts who came to support the various design institutes to conduct a comprehensive inspection, and spent 12 days working overtime to complete several static tests.

Originally, the schedule of the first flight on September 25 could only be shelved, and tomorrow is September 30, and there is only one last day left before the National Day, which is the last opportunity for the first flight.

It was already 20 o'clock in the evening, but Seryov looked at the chief teachers and researchers present, waved his hand and shouted:

"Come here today, fly tomorrow!"

Standing under Tengyun's wide wings, Zeng Hongwei, who was personally checking the heat-insulating skin with a flashlight, put away the flashlight when he heard this, and slowly climbed down the mobile escalator.

Tengyun is a very large man, with a height of more than 5.8 meters, and the ground maintenance must rely on escalators, and it is very uncomfortable to keep his head up.

Zeng Hongwei moved his neck and walked to Seryov's side, and then put his eyes on Tengyun's body:

"Mr. Xie, will you go into orbit on your first flight? Isn't that too risky. ”

Seryov: "It's all the same, don't think of it as an airplane, it's a spacecraft, its reliability requirements and design process are different from airplanes, have confidence in our rockets."

Look, our test pilots...... How hard do astronauts work? ”

Along his fingers was the cloud-lit cockpit glass, which housed four astronauts, two of whom were flight engineers, were conducting their final simulations.

The theoretical limit flight interval for H1 is 7 to 10 days, H2 is at least 15 days, and the design interval for Tengyun is 2 hours.

Theoretically, Tengyun doesn't even need maintenance after landing, you can go to space again with a full tank of fuel, 15 round-trips to the atmosphere require a 24-hour maintenance and inspection, 60 take-offs and landings need to be returned to the factory for 3 days of medium-term maintenance, and every 240 flights require regular inspections and mandatory overhauls.

As for its take-off and landing life?

1000 times, and can be extended depending on the condition of the body.

The ex-factory price of each Tengyun is 3.8 billion yuan, plus 900,000 yuan of fuel and other expenses for a single flight, and the cost of a single flight is 4.7 million yuan for 1,000 lifetimes, and it can carry 22 passengers, including two pilots, that is, more than 200,000 yuan per person.

If you don't calculate the cost, it's cheaper, 40,900 yuan to send a talent, and if you don't go out of the capsule, the cost of a single astronaut going to space can definitely be controlled within 100,000 yuan, which is so cheap that it is staggering.

This is largely due to Tengyun's insistence on using liquid oxygen methane fuel, which is a bit worse than the SSTO, and the fuel is only more than 400,000 yuan for a refueling, and the liquid oxygen and liquid hydrogen are not at such a good price.

130 tons of liquid oxygen liquid hydrogen fuel costs almost 2.1 million yuan, the price is not too high, but the transportation and storage costs must not be ignored, and the zero evaporation storage tank is also quite expensive!

This is definitely an epoch-making product in the history of astronautics, if the Xinyuan-4 rocket is the ultimate product of the violent concept of chemical engines, Tengyun is the last trace of potential of the chemical fuel itself at the technical level.

It is no exaggeration to say that the appearance of Tengyun is equivalent to the launch of a dreadnought, directly sweeping all the previous orbital spacecraft into the garbage heap, symbolizing the end of an era.

The beginning of the next era, although still brewing at the Aoyama base, is also trying to approach the limits of nuclear fission technology.

Seryov is now personally grasping the three spacecraft projects of Tengyun, Xinyuan-4, and XN90 at the same time! Tengyun can really only be ranked in a secondary position in his eyes, and he is not so cautious.

Although this attitude is a bit arrogant, Zeng Hongwei is even more admired, during the time he has worked together, he has thoroughly seen the super high efficiency and reliability of the entire Xinyuan company, and they have become accustomed to "aggressiveness".

"Okay, then I'll check the landing gear again."

Zeng Hongwei turned around to find the inspection manual and continued to groom the feathers of this fantastic super flying machine before it soared.

……

The hangar has a gap that can accommodate trucks, but it is so narrow in contrast to its huge size that you can only feel how huge it is when you get closer, and understand why giant rockets and giant planes were born here.

Lin Ju parked the unmanned electric car in the factory area that looked like a golf cart outside the hangar door, walked down and stood by the door to expose half of his body, admiring the Tengyun parked inside.

The assistant who was kicked by him a few days ago also walked silently to his side, looking at the brightly lit hangar from here reminded her of a text called The Story of the Peach Blossom Spring, the heavy door of the hangar isolates the dark night outside, and the lights inside are never extinguished, it is a separate world that will never have a sunset, vast and small, and the crowd shows the emptiness of the independent world.

This is the essence of human aerospace and aviation, for practitioners, I am afraid it is really a peach blossom source, right?

She told Lin Ju about her feelings, and the latter tried his best to imagine this kind of scene, and really felt the kind of romance that was somewhat illusory.

Lin Ju now knows how big the difference between men and women thinks, when he first built the An-1250 giant transport plane, he and Anderov were also standing here, and the latter directly opened his arms and shouted: "I want to build a big thing that can fill this place!" ”

The rugged pride is exciting, but the delicate passivity is also unique.
