Rebirth: Fight For Life

  Chapter 702 Aeroplane Engine Test

  Before the storm came, it seemed to be relatively calm.

   The standoff between HSDA and ESG, too.

  Gu Song has participated in high-level discussions many times because of his identities in the Cultural Development Center and the Cultural Development Committee. As evidenced by the events in his memory, he found that the changes have been very great.

   In this case, how could he just "dream" into the future?

   However, some of the thoughts put forward by Gu Song are still highly valued.

  Gu Tao and Bao Jiaqi can understand his prudence, no matter what guesses they have about Gu Song's "ability", it can only be left to Gu Song to decide what to say and what not to say.

   This cannot be forced.

   Anyway, go and see.

   It has been nearly two years since the outbreak of the crisis, and Huaguo has been transformed and has stood firm.

   is much more stable than Gu Song remembers.

   This kind of stability will add more chips in July.

  The Dongliao was completed, and the news was released.

   In front of this news, countless people were silent.

   Especially the maritime neighbors of China.

too fast.

  From 2006 to now, 5 years, the changes are too fast.

   We are about to face a lot of strategic issues. The meeting here is not over and the conclusion has not yet come out. It is like a fast-paced movie, chapter by chapter.

  …

   Musk knew about the news, and he also knew that Gu Song had a role in it.

   Now recalling the first meeting with him in early 2006, Musk occasionally felt a little uncomfortable about his indiscretion at that time.

   Who would have thought that at that time, this person who seemed to be Jobs's old enemy was actually his own.

  Smartphone...just a toy he made by accident, right?

   Compared with quantum computers, Candle Dragon No. 2, and Flint Space City, what is a smartphone?

   And now, aerospace, electric vehicles, this guy is in the game.

  All solid state battery…

   Musk has a big head, but he has to concentrate and pay attention to the launch in front of him.

   Falcon 9.

  Because it has received a large amount of financial support and even technical support, this rocket has been much ahead of the planned schedule and has completed 2 test launches.

   is not a success.

   But now, good news is needed.

   This time, not only the Falcon 9, but also the Dragon spacecraft.

   Now, the Dragon spacecraft has been successfully tested on the old mature rocket, and the Falcon 9 has also accumulated two launch experience. They become one, and this time it has to be successful.

   After the North Bear Country withdrew, it was necessary to restore the capabilities of another cargo spacecraft and manned spacecraft in addition to the space shuttle as soon as possible.

   stood beside him, and the NASA guys.

   "How sure are you?"

   "Trust me, Roman." Musk looked confident.

  Inspired by Flint Space City, both SpaceX and other partners have increased their investment in this field.

  Many powerful scientists and engineers have also been inspired to fight and be enthusiastic.

  The International Space Station has also carried out three supply launches this year, adding node modules. Although this speed cannot catch up with Flint Space City, it also shows ESG's determination.

  Unfortunately, this time the Dragon spacecraft is still only tested and launched by Falcon 9, and will not consider docking with the International Space Station.

   After all, there is only one International Space Station. If the docking between the Dragon spacecraft and the International Space Station fails, causing serious consequences, it cannot afford it.

   In a short period of time, the capacity of NASA and ESA is too limited to quickly rebuild an Uranos.

  No matter how confident Musk is, the people above would not dare to take such a risk.

  …

   At this time, Gu Song took Xie Yinran, who had just graduated, to Nanhai Island for vacation.

  Gu Song is of course not here for a holiday.

  The design idea of ​​the Pangu Industrial Space Station needs to be discussed and connected with the technical team of Huayu Heavy Industry.

   And the more important work is the aerospace aircraft project that He Anzhi, Fan Yuanbai and Guo Yue are jointly tackling.

  This time is different from the past, Guo Yue has officially jumped into the system of Flint University of Aeronautics and Astronautics and Flint Aerospace.

  The project team of aerospace planes is not small.

   Bai Yang is also in Guo Yue's software engineering team. He was originally Guo Yue's student, and he is very familiar with it.

   But today's highlight is the engine test.

  Guo Yue stood on the huge rocket engine test bench, looked at this bizarre building, and said worriedly: "Is this thing really possible?"

  He Anzhi said confidently: "Don't worry, the decentralized test of each stage has been done, and it is very reliable. Now the main thing is to test its switching in various states."

  Guo Yue said with emotion: "Single-level entry into orbit... The technical content of this test bench is the first in the world."

  He Anzhi was very proud. Even though Lao Guo has become an engineering academician, he is not a student when he arrives here.

   Gu Song said with a smile: "It's unprecedented, it's ugly, it's just a little bit ugly, it just needs to be able to support tests in different states."

   Unlike ordinary rocket engine tests, the aerospace plane engine is a completely different concept.

  The engine of the aerospace plane has to use a combined cycle design. Because it has to realize the take-off of the aerospace plane on the ground, the low-speed operation in the air environment, the high-speed breakthrough of the earth's gravity, and the final propulsion in the vacuum environment.

   Flint Aerospace directly chose the rocket-based combined cycle power plant route RBCC, which is the most difficult and most representative of the future.

The   RBCC propulsion system is an integration of a rocket engine and an air-breathing engine, and is an integrated propulsion system that combines these two types of engines.

   In the take-off phase, the subsonic combustion mode of the ramjet is used.

  Wait until the speed of the aerospace plane exceeds Mach 5, it will enter the supersonic combustion mode of the ramjet.

   Speed ​​up again, switch to rocket mode, rush out of the atmosphere, and propel in a vacuum.

   The design and manufacture of this engine is itself a huge difficulty. And the test of it also has high requirements on the test bench.

   This is an engine with a thrust of a thousand tons or even higher, so the firmness of the test bench is not to be mentioned.

   When the engine is started, the exhaust gas and energy discharged must be treated properly.

   And because it is an RBCC propulsion system, it has to be able to switch between the air state and the vacuum state.

The technical content of    can’t be said, but Guo Yue can’t complain that the technical level of this test bench is probably the best in the world.

   Now, the main thing is to test the data of this engine separately before the test in the sky, especially the problem of switching in different states.

  Gu Song's low R&D cost and high investment determine that he can play in this way.

   This is something no one else can learn.

   This is also the reason why the breakthrough of Flint Aerospace will be so fast.

   "Are you ready?"

   Fan Yuanbai and Guo Yue both came to watch, and He Anzhi was in charge of the engine.

   "I'm ready, I'll wait for your order."

  Gu Song said with a smile: "Let's start with this form."

With the    order, before the engine started, the water spray device had begun to work violently.

  The water spray is to absorb the energy discharged by the engine, and the other is to absorb the acoustic vibration and reduce the noise.

  In the working state, the power of each square meter in the combustion chamber of the engine reaches more than 100G watts. You know, ordinary thermal power plants generally only generate single-digit G watts of power.

  Although these two are not suitable for comparison, at least one can intuitively feel how violent the engine of the aerospace plane is.

   As the flames spewed out, a large amount of water vapor was instantly excited, and the test began.

  The exhaust gas from the engine is sprayed into the sky through the pipe. The intake duct draws air from the sky, and the exhaust duct blasts air into the sky, creating a huge turbulent area above the test bench.

  Because of this test, the nearby low-altitude airspace has been banned from flying.

  Weighing thousands of tons, the test bench built to the highest specifications is pressing down on this furious engine!
