Chapter 1635 Hypersonic suborbital returnable spacecraft

Previous page        Return to Catalog        Next page

    Zhuang Jianye nodded after hearing this. He didn't say anything, but looked out the window. It was the end of May, and the Luliang Mountains had been dyed with a layer of fine new green, but Zhuang Jianye's mood was not as comfortable as the spring outside.

    There is no longer the joy of negotiating a controlling stake in an express delivery company and building a factory in partnership with foreign capital.

    Let¡¯s not talk about what he saw in the W earthquake-stricken area some time ago, which shocked Zhuang Jianye¡¯s senses and soul, but regarding this ¡°spacecraft¡± test, to be honest, the pressure Zhuang Jianye endured made him unable to laugh even if he wanted to.  come out.

    The name of this "spacecraft" test is called "Hypersonic Suborbital Spacecraft Return Test." At first glance, it seems that this test is similar to the return capsule of returnable satellites and manned spaceflight. They are all return-type spacecraft.  From a technical point of view, it shouldn't be difficult.

    However, from the actual effect point of view, the difficulty of this thing has simply reached a level of "change~~~ state".

    Precisely because of this, the United States and the former Soviet Union successively proposed relevant technical solutions during the Cold War. However, due to technology, cost, and many difficult-to-solve problems, this suborbital hypersonic spacecraft was never realized.

    After the Cold War, the dominant United States wanted to continue to persevere and proposed the concept of the "Dawn Goddess" suborbital high-speed bomber. However, later because the technology was too advanced, the value and cost greatly exceeded the budget, and it believed that its existing military power was enough to dominate.  This blue star cut off this project.

    Since then, no one has been involved in this technical route. There is no way, not to mention that this thing is a bottomless pit, and the success rate is still extremely low. Especially after the US technical route was discontinued, no one had the courage to try it.

    You must know that it is not as simple as sending a spacecraft into orbit and then returning. An ordinary launch vehicle will make a typical high-throw ballistic trajectory, and the starting point and landing point will be clear at a glance.

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

    This requires that this type of spacecraft must first have an extremely powerful power system, and this power system must be very powerful, at least capable of accelerating this type of spacecraft to supersonic speeds of Mach 5 to Mach 10.

    The second is suborbital flight, which is not the kind of space flight that follows a predetermined orbit, but a free flight like an aircraft that can change directions at will in the suborbital orbit.

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

    If you can do the above three points, congratulations, you can definitely walk sideways in the world, because even Americans are so overwhelmed by these three points that they have to give up in the end.

    Even Americans are lying flat, let alone other countries in the world.

    China¡¯s take-off actually wants to stay on the same side, but there is no other way. It is really too technically difficult, and it gives me a headache just to look at it. But the problem is that the actual situation does not allow China¡¯s take-off to muddle along.

    Because of some well-known reasons, if you don¡¯t have something at the bottom of the box, you would be embarrassed to stand up and shout something in the global village.

    So China¡¯s take-off is impossible. Who makes them the main contractor 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, superiors gave this task to China Ascendas. Even though the "Dawn Goddess" project was later canceled by the Americans, China Ascendas continued to persist.

    Of course, China's take-off cannot be as blatant as the Americans. Instead, it is positioned as a "civilian" space vehicle. After all, China's take-off is for world peace and human development, and will never produce militarized equipment.

    What?  Carrier-based aircraft?  Military transport plane?  And anti-ship ballistic missiles?

    Please open your eyes and take a closer look. Are special air transportation platforms used for the takeoff and landing of large ships, ultra-large air transportation platforms used for the transportation of oversized materials, and long-distance precision recovery of spacecraft considered weapons and equipment?

    They are just special transportation systems. Just like trucks on the road, trains on the railway, and freighters on the sea, they are all loaded with cargo.

    You can¡¯t say that they are weapons and equipment just because they carry explosive missiles and bombs, right?

    So, tank trucks are still explosive and dangerous goods. Why not classify such things as weapons and equipment?

    So, China Tengfei is not a manufacturer of weapons and equipment, it is just a porter of special goods!

    Precisely because of this, China Tengfei has never admitted that it is an arms manufacturer because it has never produced arms.Why is it an arms manufacturer? It just creates platforms suitable for users based on their specific habits. As for whether users use these platforms to deliver express delivery or blow up bunkers, it doesn't matter what happens to China.

    Based on this lofty concept that China Takeoff has adhered to since its establishment, this type of "hypersonic suborbital returnable spacecraft" naturally has no militarization at all. It is entirely an effort to enable mankind to peacefully use outer space in the future.  A cheap and efficient spacecraft built.

    Therefore, China Takeoff's vision is to use this "hypersonic suborbital returnable spacecraft" to implement one-hour express transportation around the world. After all, for some important customers, the faster the better, the market demand is still  very big.

    Based on this, everyone from Zhuang Jianye to the ordinary technicians involved in this project feel that they are shouldering an extremely lofty mission, with "world peace" on one shoulder and "human development" on the other.  "Conquering the stars and the sea", forget about that feeling, it will happen in minutes

    However, Zhuang Jianye and others above were quickly poured cold water on their heads. In the second half of last year, the "hypersonic suborbital returnable spacecraft" conducted its first flight test. As a result, the launch vehicle released the "ultra-high speed  After the "hypersonic suborbital returnable spacecraft", when the aircraft fell according to the normal ballistic trajectory, the internal engine did not start normally, making the "hypersonic suborbital returnable spacecraft" eventually become an ordinary "return time"  "Spacecraft" plunged into the Gobi Desert in the northwest.

    Afterwards, it was concluded that there were many reasons for the failure. For example, insufficient understanding of the suborbital conditions of 80 to 200 kilometers led to unreasonable internal engine ignition settings; another example was that the measurement and control signals were unstable and the "supersonic suborbital" could not be stably controlled.  "Returnable spacecraft"; also such as interference from different radio signals from multiple directions during the entire test process, etc

    But no matter what the reason is, the most critical thing is that China Ascendas' own technology is not up to standard. Therefore, after learning from the pain, China Ascendas spent half a year to eliminate a series of problems and once again carried out the "hypersonic suborbital returnable spacecraft".  "The test flight test will be successful or not. To be honest, Zhuang Jianye doesn't dare to guarantee it!"
