  Chapter 178 True Independent Research and Development

  The car stopped.

   Tang Rui and Academician Li walked into a huge underground space.

   After entering it.

   I saw a huge aircraft.

   The adjective is not wrong, it is huge.

   "This is the second verification aircraft, with a length of 38.42 meters, a height of 12.25 meters, a wingspan of 27.15 meters, a fuselage diameter of 7.2 meters, a maximum take-off weight of 122 tons, and a return landing weight of 92 tons."

  Academician Li casually broke out the parameters of this aircraft.

  As the chief designer.

  He knows all the performance parameters of this aircraft like the back of his hand, and he knows everything by heart.

   "What kind of fuel is used?" Tang Rui asked looking at the rocket engine nozzle at the rear of the aircraft.

   "Liquid Oxygen Kerosene."

   "Can I see the details of the engine?"

"sure."

  After academician Li finished speaking, he asked someone to bring the computer.

  Tang Rui looked at the data on the computer and asked Honglian to simulate.

   Sure enough, it is very advanced.

  It is a level stronger than the engine technology he bought back from Da Mao, and many things have made new breakthroughs.

  After Tang Rui read it, the simulation on Honglian's side also ended, and the conclusions reached were similar to the above data.

   But such data is not enough to support the repeated orbiting and long-term flight of suborbital vehicles.

   But this is not a big problem.

  According to the above plan design, they already have an idea, and the next step is a little bit of research and experimentation.

   "Academician Li, how are you going to solve the maneuverability problem of the aircraft?" Tang Rui continued to ask after putting down the computer.

   "We are also studying this issue. At the beginning, we plan to adjust the lift structure and match the layout with flexibility.

   But you also know that the altitude at which the suborbital vehicle flies does not actually support the aerodynamic layout.

   On the contrary, the structure of the waverider is more suitable for suborbital flight, but there are also problems. The waverider is good, flexible and flexible, but it is also difficult to control. "

  When it comes to this point, Academician Li is also very helpless.

  A sub-orbital vehicle is equivalent to constantly drifting against the atmosphere. In this case, it is really difficult to take into account flexibility.

   "Mr. Li, haven't you tried using rocket injectors to adjust the direction?"

   "You mean the vector nozzle?"

   "No, I mean, install a few rocket injectors on the body of the aircraft, and when used, use the reaction force to modify the direction of the aircraft?"

  The train of thought Tang Rui said was the train of thought of his aerospace fighter maneuvering in outer space.

  After reaching outer space, the aerodynamic layout is gone.

  An aerospace fighter must be equipped with propulsion equipment if it wants to maneuver. His aerospace fighter is equipped with an electric propulsion engine.

  But electric propulsion engines cannot be used on suborbital vehicles.

  Because the thrust is too low.

  After listening, Academician Li shook his head after pondering for a while.

   "The idea is fine, but the overall structure of the aircraft can't bear it, let alone the pilot.

  Unless a breakthrough is made in relevant materials, and the anti-G suit of the pilot can also withstand the overload of 10 G.

   Otherwise, this idea cannot be realized. "

   After thinking about it, Mr. Li shook his head and said.

   "What a coincidence, I have both of these." Tang Rui laughed after hearing this.

   "Really." Academician Li was very excited after hearing this.

   "Well, I can solve the materials and anti-G suits. But I can't help with the redesign of the body structure."

   Tang Rui nodded and said, but he was only providing materials and would not interfere with the research.

   Academician Li has already done a good job here, unless he is bored, he will come to join in the fun.

Moreover.

  If he wants to study, he also studies outer space.

   But that thing is not in a hurry.

   Finish what is on hand before talking.

   "Of course, if you help solve everything, what are we going to do?"

   It can be seen that Academician Li is very happy.

   Academician Li, who lost a piece of heart disease, happily dragged Tang Rui around, showing him some new things.

   Among them is a supercritical wing manufacturing equipment. Tang Rui looks very good, and it is also very useful to him.

  Academician Li saw that he was interested, so he ordered one for him.

  Tang Rui quickly shook his head and refused.

  He has already understood the design idea of ​​this thing, and he can just ask Honglian to build one when he goes back, there is no need to order it specially.

  After visiting here for a while.

  Tang Rui said goodbye and left.

  Academician Li is also quite busy, and the people under him are even busier, so he didn't continue to disturb others after the visit.

  Go back to the place where the rocket was tested.

   That's a downhill slope.

   There is water below the slope.

  The solid rocket motor brought by Tang Rui is being tested on the test bench.

A few minutes later.

  The fuel in the powder column is consumed, and the flame of the rocket nozzle disappears, leaving only a slightly red nozzle.

  With the high-temperature-resistant material in Tang Rui's hands, it can prevent the nozzle from turning red, but that is meaningless.

   This is the engine of the missile.

  When the missile is launched, it will explode.

  As long as the material can be used, there is no need to make it so good, it is a waste of money.

   "Mr. Tang, all the test data are here, please confirm." The data on the test bench has been stored in the mobile hard disk, and the data in the computer has been deleted.

   After Tang Rui took over the mobile hard disk, he connected it to the computer.

  He just glanced briefly.

   After confirming that there is no import error in the data, the computer is turned off.

   The specific data analysis and sorting, Honglian will do a good job, don't worry about him.

  The next half day.

  Tang Rui is here on the test bench. With the ignition test of the engine again and again, more and more data are obtained.

  Guren has sorted out the data.

  Based on the actual test comparison.

  The actual parameters of this solid rocket motor are a little worse than the theoretical design parameters.

   The difference is not much, but the difference in thrust is 0.03 kg.

  This is completely negligible for solid rocket motors, because under normal circumstances, the missile has already destroyed the target before the fuel runs out.

  So this difference is nothing at all.

afternoon.

  Tang Rui happily returned to the company.

  The reason why he is so happy is mainly because this engine is completely designed by himself.

   Red Lotus is only used as a calculation tool to assist the design, and has not participated in any modification.

  What does this mean.

  The knowledge he learned was not in vain.

  As long as he wants to do research, he can still do it.

  This feeling is very different.

   "Guren, first produce ten missiles, and use this engine designed by me."

  After returning to the laboratory, Tang Rui asked Honglian to produce ten missiles first. After they were built, he wanted to find a place to test them.

   "Okay, master, the production has already started, and it is expected to be completed tomorrow morning."

   buzzing...

   Just when Tang Rui was about to say something, his cell phone rang.

   It was Lin Chao calling.

   "Brother Lin, what's the matter?" Tang Rui asked directly.

   If there is nothing wrong, Lin Chao will not call him. If it is not urgent, he will tell him when he is eating.

  As long as you call, it is urgent.

   "Mr. Tang, the police contacted me just now, saying that the Skynet drone you sold to the police has set a border ban."

   "Yes, that's right, the program I reserved in the drones of Skynet, as long as these drones want to fly out of the country, once they reach the border, they will automatically return and will no longer be controlled by the ground control system."

   Tang Rui thought for a while, nodded and said.

  He set up this program at the beginning because he was afraid that the image algorithm would be exposed.

  The image algorithm of the Skynet UAV is not the version he sold to Huawei. Although it is not a complete version, its ability to process images is already very good.

   If this algorithm is obtained by foreign countries, it is not a leak.

  So, when he was designing, he added this hidden program.

Normally.

  This sequence will not be activated.

   After all, the police use drones to patrol, and it is impossible to go abroad, isn't that nonsense.

   "That's right...I see, I will explain the situation to the police." Lin Chao was about to hang up after listening.

   "Wait... Brother Lin, why are you asking this?"

   "It's like this. When the funds in the Yun Province area used Skynet drones to search for a cross-border criminal gang, they found that the other party had already escaped the border.

  The police wanted to use drones to track the opponent and find the opponent's lair.

  As a result, the drone returned uncontrollably as soon as it flew to the border, and the police called to inquire about the situation. "

  After listening to what Lin Chao said, Tang Rui understood what was going on.

   This is a joke.

   "Brother Lin, give me the phone number over there, and I'll contact them."

   Tang Rui's eyes suddenly lit up, thinking of something.

   If I’m not in the mood today, I’ll update Chapter 4. I can’t write Chapter 5. Go to bed early and get up early tomorrow to code.
