Chapter 1634

Zhuang Jianye nodded and didn't say anything. Instead, he looked out of the window. At the end of May, the Luliang mountains had been dyed with a layer of fine new green, but Zhuang Jianye was not as comfortable as the spring outside.

There will be no pleasure in negotiating the holding of an express company and building a factory in partnership with foreign capital.

Not to mention what we saw in the w earthquake stricken area some time ago, Zhuang Jianye was impacted on his senses and soul, but for this "spacecraft" test, to tell the truth, the pressure Zhuang Jianye endured also made him unable to laugh.

The name of this "spacecraft" test is called "super high speed suborbital spacecraft return test". At first glance, it seems that this test is similar to the return capsule of return satellite and manned spaceflight. They are all return spacecraft. From a technical point of view, it should not be difficult.

However, in terms of practical effect, the difficulty of this thing has almost reached a degree of "change ~ ~ ~ state".

Because of this, the United States and the former Soviet Union successively put forward relevant technical solutions during the cold war. However, due to technology, cost and many difficult problems, this suborbital ultra-high speed spacecraft simply did not realize.

After the cold war, the dominant United States wanted to continue to insist and put forward the concept of "dawn goddess" sub orbital high-speed bomber. Later, because the technology was too advanced, the value cost greatly exceeded the budget, and it thought that the existing military strength was enough to rule the blue star, it cut down the project.

After that, no one was involved in this technical route. There was no way. It was really a bottomless hole. The success rate was still very low, especially after the American technical route was dismounted, no one had the courage to try.

You know, it's not as simple as putting space into orbit and then returning. An ordinary launch vehicle makes a typical high throw trajectory, and the starting point and landing point are clear at a glance.

"Super high speed suborbital returnable spacecraft" is not the case. It is a new spacecraft that can not only fly at high speed in suborbital between 80 and 200 kilometers, but also land at any point accurately according to the situation at any time.

This requires that this kind of aerospace first have a very strong power system, and this power system must be very strong. At least, it can accelerate this kind of spacecraft to the ultra-high speed of Mach 5 to 10.

The second is the suborbital flight, which is not the space flight according to the predetermined orbit, but the free flight in which the direction can be changed at will in the suborbital like an aircraft.

The last and most important thing is to be able to return and land accurately according to the instructions.

If you can achieve the above three points, Congratulations, you can definitely walk horizontally in the world, because even Americans are overwhelmed by these three points and have to give up at last.

Even Americans lie flat, let alone the rest of the world.

China's take-off actually wants to lie flat. There's no way. It's really too difficult in technology. It's a headache to see, but the problem is that the reality does not allow China to take-off and muddle along.

For some well-known reasons, if you don't have some belongings at the bottom of the pressure box, you're really embarrassed to straighten your waist and shout in the global village.

Therefore, China's take-off is not up. Who makes them the main contractors of domestic anti-ship ballistic missiles and hypersonic weapon systems, with rich experience in the development of suborbital vehicles?

So as early as the late 1990s, the superior entrusted this task to China's take-off. Even if the "goddess of dawn" plan was dismounted by the Americans, China's take-off continued to adhere to it.

Of course, China's take-off can not be as blatant as the Americans, but positioning it as a "civil" space vehicle. After all, the purpose of China's take-off is world peace and human development. It will never produce militarized equipment.

What? Carrier borne machine? Military transport aircraft? And anti-ship ballistic missiles?

Please open your eyes and have a good look. Besides, are special air transport platforms used for the take-off and landing of large ships, super large air transport platforms used for the transportation of large-scale materials and long-distance accurate recovery spacecraft weapons and equipment?

They are all special transportation systems, just like trucks on the road, trains on the railway and cargo ships in the sea.

Can't they be said to be weapons and equipment just because they are equipped with explosive missiles and bombs?

So oil tankers are still dangerous goods that can explode. Why not classify such things as weapons and equipment?

Therefore, China Tengfei is not a manufacturer of weapons and equipment. He is just a porter of special goods!

Because of this, China Tengfei never admits that it is an arms manufacturer because it has never produced arms. What makes it an arms manufacturer is that it just makes a platform suitable for users according to the specific habits of users. Whether users take these platforms as express delivery or blow up blockhouses, it doesn't matter what China Tengfei does.

Based on this lofty concept that China's take-off has adhered to since its establishment, this kind of "super high speed suborbital returnable spacecraft" naturally has no military color at all. It is entirely a cheap and efficient spacecraft for the peaceful use of outer space in the future.

Therefore, the vision and goal of China's take-off is to use this "super high speed suborbital returnable spacecraft" to implement the global one hour express transportation. After all, the faster the express delivery of some important customers, the better, and the market demand is still great.

Based on this, from Zhuang Jianye to the ordinary technicians participating in this project, they all feel that they are shouldering an incomparably noble mission, carrying "world peace" on one shoulder and "human development" on the other, and all they can see is "conquering the stars and the sea". That feeling is not to mention, it's up in every minute

However, Zhuang Jianye and others at the top were soon doused with cold water. In the second half of last year, the "super high speed sub orbital returnable spacecraft" conducted its first flight test. As a result, after the launch vehicle released the "super high speed sub orbital returnable spacecraft", the internal engine did not start normally when the spacecraft fell according to the normal trajectory, The "super high speed suborbital returnable spacecraft" finally became an ordinary "return spacecraft" and plunged into the northwest Gobi desert.

Afterwards, it was concluded that there were many reasons for the failure. For example, the lack of understanding of the suborbital situation of 80 to 200 km led to the unreasonable procedure of internal engine ignition setting; Another example is that the TT & C signal is unstable and it is unable to stably control the "super high speed suborbital returnable spacecraft"; For example, the interference of different radio signals from multiple directions during the whole test process

However, no matter what the reason is, the most important thing is that China's take-off technology does not pass the test. Therefore, after learning from the experience, China's take-off again conducted the test flight test of "super high speed sub orbital returnable spacecraft" after eliminating a series of problems for half a year. To tell the truth, Zhuang Jianye is not sure!
