Gao Qitao's matter can only be regarded as a trivial matter here in Lin Ju, but the uncontrolled airspace and free flight have indeed brought a lot of trouble to the surrounding cities and counties of Xinyuan.

Although Aramco is more open than China, and the number of small private jet owners is tens or hundreds of times, the difference is still significant.

Ami is a large plain terrain, the population is not large, most of the area is large farms, and the flight density is not very high, so the impact is average.

But the surrounding area of Xinyuan is different, the population is concentrated, and there are many planes at Hushan Airport, only a few months, the number of small and medium-sized sports aircraft stationed at Hushan Airport has exceeded 1,300.

With so many planes, especially the thousands of students of Xinyuan Flight School, there are often rookies who fly blindly over the city, and every day when the air traffic control opens its eyes, the radar is densely packed with a large area, and there are so many planes that people are delirious.

Although there have been no major accidents, nearly 1,000 planes fly around every day, which has brought huge supporting facilities and tourism income to the surrounding area while also having a great impact on daily life.

In July, several colleges and universities that cooperated with Xinyuan were closed, and 87% of the nearly 3,800 students chose to stay here to learn to fly, and then the instructors took the opportunity to bring the first batch of graduates to show flying.

There is no work, just the formation flew over the sky over the surrounding three counties and two cities, how much...... 470 aircraft.

The surrounding residents really felt the scene of the bombing of thousands of planes, nearly 500 planes flew densely from a low altitude, and felt that the whole city was shrouded in the sound of aero engines.

Now even the above is a little regretful, originally thought that it would be a reward for a company like Xinyuan to approve free airspace for test flight aircraft or something, but flight school like this......

This hole is too skillful, and it is not easy to recover it now, what should I do with more than 2,000 planes in Xinyuan? What about Hushan Airport, which is an extremely important economic growth point for the local area? What about the supporting industries that have been established for more than half a year?

The superior leaders are also having a headache, and Xinyuan's current status is also very important, so he must be unhappy if there is a change rashly, so he must be safe.

As for Lin Ju himself, he only thinks that the Gao Qitao incident means that the talent pool built by Xinyuan has finally been effective, and the new employees in the future are all-round talents who can bury themselves in building rockets and dig helium three on the moon.

Speaking of the moon, Lin Ju is now in the capital, watching a test at a certain test base.

In a wasteland, a lander-like object was chained to a pillar around it, and then the engine beneath it started, spewing out a pale blue tail flame that sent the lander into the air and hovered for more than ten seconds, and then reduced its thrust and smashed into the ground.

"This is the 8-ton liquid oxygen liquid hydrogen rocket engine we are preparing to use for the moon landing, which was modified from YF75D and is now called YF75M."

The person in charge here said that because it works in a vacuum, the engine nozzle of this YF75M is particularly large, but on the ground because the test conditions are different, and there is a little change from the reality.

Now in the Dawning plan, the mass of the lunar lander is about 25 tons, and the landing engine is this YF75M, with 8 tons of thrust, which is completely enough for the moon with only one-sixth of the gravity of the earth.

The lunar landing plan was also determined, and the spacecraft carried three astronauts, one in low-earth orbit and two on the moon.

It should be mentioned here that after the implementation of the Dawning Plan, the Aviation Development Commission believes that since China is already preparing to carry out extraterrestrial landing missions, the title of astronaut can be abandoned and the use of "astronaut" is more appropriate.

Although there are no official documents, the number of official use of astronauts has increased.

Lin Ju also knows that if the YF90 and 220-ton hydrogen-oxygen engine of the rich combustion cycle are successful before 2020, then the second stage of the Long March 10 will be replaced with this engine, and the lunar orbit capacity will be increased to 50 tons, and then it will be able to take four astronauts and try to land three or four people on the moon.

However, the outlook for the YF90 is clearly not too rosy.

Accompanying Lin Ju here is Academician She, the general director of the Dawning Project.

Academician She: "The YF77 test results came out, 12 production defects, 7 design defects, the Sixth Academy promised that it would be solved within 6 months, but I still feel a little troublesome." ”

It's not just a bit of trouble!

Lin Ju knew that the YF77 had a failure during the test in 2019 in the original world line, and it was only in this year that it was completely stabilized, and then the old Long March 5 ushered in a period of high-frequency launches.

Suffice it to say that in the last world line, if YF77 hadn't dragged its feet, the space station would have been built before 2020.

Therefore, although YF77 has definitely increased the scale of personnel and technology investment due to the high investment of the Dawning Project, it is really difficult to say whether it can become reliable three years ahead of schedule.

The hydrogen-oxygen engine seems to be a bit inconsistent with the space agency, and the YF77 specific impulse, thrust-to-weight ratio, and thrust are all a little backward in the direct, but they still stumble, and I don't know where it's stuck.

But Academician She obviously foresaw this, so a few days ago, the First Academy placed an order to buy 1 H240 and 1 H80.

Obviously, if the YF77 is not reliable enough, it will replace the second and third stages of the Long March 10 with an H240 and an H80, but this is a desperate move, at most it will be used for the second launch, and the YF77 will definitely have to be used in the follow-up, especially the official landing on the moon.

The biggest significance of the Long March 10 is that the space agency used a self-developed rocket to send astronauts to the moon, and every word is very important.

Lin Ju: "Xinyuan will fully support the Dawning project, as long as we have, we can provide it to the Long March 10, so that if the design and materials of YF77 encounter some difficulties, Xinyuan may be able to provide technical support." ”

"Technical support?" Academician She was a little surprised.

Since K120, Xinyuan has not carried out any space engine technology exchanges with the outside world, and there is no need for them, their engine technology is amazingly high, and they have never seen failure!

However, the space agency has a very high evaluation of the K120, with high specific impulse, large thrust, high thrust-to-weight ratio, and small size, which is simply a delicate work.

The potential of the K120 is also very large, and after the evaluation of the Sixth Academy, it is believed that if the combustion chamber pressure is continued to be increased and the nozzle diameter is slightly enlarged, a 200-ton single-combustion chamber high-thrust kerosene engine can be developed, but this plan is replaced by the more powerful YF135.

But even the YF130 and YF135 still carry the bloodline of K120, which can be said to be heirloom.

Lin Ju did not attach much importance to the technical support of the space agency, and the space agency was not without strength, and the YF90 and YF79 developed for the Long March 9 in their plan, especially the latter's closed-cycle hydrogen-oxygen engine, can be said to be the most advanced in the world at the same level.

Traditional technology should be a push CASA.
