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 correct, 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 and landing weight of 92 tons."

Academician Li casually revealed the parameters of this aircraft.

As chief designer.

This person knows all the performance parameters of this aircraft very well and knows them by heart.

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

"Liquid oxygen kerosene."

"Can I see the details of the engine?"

"sure."

After Academician Li finished speaking, he asked someone to get the computer.

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

It's really advanced.

It is a level better than the engine technology he exchanged 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 data above.

However, such data is not enough to support multiple repeated orbits and long-term flights of suborbital spacecraft.

But this is not a big problem.

Based on the above plan and design, they already have an idea, and the next step is to do some research and experiments.

"Academician Li, how are you going to solve the aircraft's maneuverability problem?" Tang Rui put down the computer and continued to ask.

"We are also studying this issue. Initially, we are going to adjust the lift structure and combine it with a layout that takes into account flexibility.

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

On the contrary, the structure of the waverider is more suitable for suborbital flight, but the problem also arises, whether the waverider is good or not, it is flexible and flexible, but it is also difficult to control."

When talking about this, Academician Li was also helpless.

A suborbital vehicle is equivalent to constantly drifting close to the atmosphere. Under such circumstances, it is really difficult to balance flexibility.

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

"You mean the vector nozzle?"

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

The idea Tang Rui mentioned is the idea of ​​​​his aerial fighter aircraft performing maneuvers in outer space.

After reaching outer space, the aerodynamic layout is gone.

If an aerospace fighter wants to maneuver, it must be equipped with propulsion equipment. The one installed on his aerospace fighter is an electric propulsion engine.

But electric propulsion engines cannot be used on suborbital vehicles.

Because the thrust is too low.

After listening to this, Academician Li pondered for a while and then shook his head.

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

Unless there is a breakthrough in relevant materials, and the pilot's anti-gravity suit can withstand a 10 G overload.

Otherwise, this idea cannot be realized."

After thinking for a while, Mr. Li shook his head and said.

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

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

"Well, I can solve the problem of materials and anti-gravity 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 in research matters.

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

Say it again.

If he wanted to study, he would study outer space.

But that thing is in no hurry.

Let’s finish what we have on hand first.

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

It can be seen that Academician Li is very happy.

Academician Li, who had removed a piece of his heartache, happily took Tang Rui around and showed him some new things.

Among them was a supercritical wing manufacturing equipment. Tang Rui looked very good and it was also very useful to him.

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

Tang Rui quickly shook his head and refused.

He has already understood the design idea of ​​this thing. 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 was also very busy, and the people under him were even busier, so he did not continue to disturb them after the visit.

Return 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 put on the test bench for testing.

A few minutes later.

After the fuel in the grain column is consumed, the flame from the rocket nozzle disappears, leaving only a slightly red nozzle.

With the high-temperature-resistant materials Tang Rui had in hand, he could prevent the nozzle from turning red, but that was meaningless.

This is the engine of the missile.

If the missile is launched, it will explode.

As long as the material is usable, 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 drive, and the data in the computer has been deleted.

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

He just glanced briefly.

After confirming that there are no data import errors, shut down the computer.

Honglian will do the specific data analysis and sorting, so he doesn't have to worry about it.

The next half day.

Tang Rui is here on the test bench. As the engine is ignited and tested again and again, more and more data are obtained.

Honglian has already sorted out the data.

Based on 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 thrust difference is 0.03 kilograms.

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

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 was completely designed by himself.

Honglian is only used as a calculation tool to assist the design and does not participate in any modifications.

What does this mean?
