The car stopped.

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

After entering it.

I saw a huge flying machine.

The adjective is not wrong, it is huge.

"This is the second demonstration 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 revealed the parameters of this aircraft.

As the chief designer.

This is a good understanding of any performance parameters of this aircraft.

"What kind of fuel is used?" Tang Rui asked as he looked at the rocket engine vent behind the aircraft.

"Liquid oxygen kerosene."

"Can I see the details of the engine?"

"Absolutely."

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

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

Sure enough, it's very advanced.

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

After reading it on Tang Rui's side, the simulation on Red Lotus's side was also over, and the conclusion reached was similar to the data above.

However, such data is not enough to support the repeated orbital entry and long flight of suborbital vehicles.

But it's not a big deal.

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

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

"We were also working on this issue, and at first we were going to adjust the lift structure to match the layout with flexibility.

But as you know, the altitude at which the suborbital vehicle flies is not very supportive of the aerodynamic layout.

On the contrary, the structure of the waverider is more suitable for suborbital flight, but the problem also comes, the waverider is good, flexible and flexible, but the control difficulty is also high. ”

When it came to this, Academician Li was also very helpless.

A suborbital vehicle is equivalent to constantly drifting against the atmosphere, and in this case, it is really difficult to take into account flexibility.

"Elder Li, haven't you tried to use a rocket jet to adjust the direction?"

"You mean vector spouts?"

"No, I mean, put a couple of rocket jets on the fuselage of the aircraft, and when used, use the reaction force to modify the direction of the aircraft?"

The idea that Tang Rui said was the idea of his air and space fighter maneuvering in outer space.

Once in outer space, the aerodynamic layout is gone.

If the aerospace fighter wants to maneuver, it must be equipped with propulsion equipment, and his aerospace fighter is equipped with an electric propulsion engine.

However, 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 shook his head.

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

Unless there is a breakthrough in the relevant materials, and the pilot's anti-load suit, it can also withstand an overload of 10 G.

Otherwise, this idea cannot be realized. ”

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

"It's a coincidence, I have both of them." 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-load clothing. But with the redesign of the mech's structure, I can't help with it. ”

Tang Rui nodded and said, but he only provided materials and would not interfere in the research matters.

Academician Li has done a good job here, unless his idle egg hurts, he will come to join in the fun.

Besides.

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

But that thing isn't in a hurry.

Let's finish what we have at hand first.

"Of course, if you 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 heart disease, happily pulled Tang Rui around and showed 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 helped him order one.

Tang Rui hurriedly shook his head and refused.

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

After visiting here for a while.

Tang Rui said goodbye and left.

Academician Li was also very busy, and the group of people under him were even busier, so he didn't continue to bother people after the visit.

Back to the place where the rocket was tested.

It was a downhill slope.

There is water underneath the slope.

The solid rocket engine brought by Tang Rui is being placed on the test bench for testing.

A few minutes later.

The fuel inside the column was consumed, and the flames from the rocket vent disappeared, leaving only a slightly reddened vent.

With the high-temperature resistant materials in Tang Rui's hands, the nozzle can not be red, but that makes no sense.

This is the engine of the missile.

If 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 is here, you can confirm it." The data on the test bench has been stored on the portable hard drive, and the data on the computer has been deleted.

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

He just glanced at it briefly.

After confirming that there are no import errors, turn off the computer.

Specific data analysis and sorting, Red Lotus will do a good job, don't worry about him.

The next half day.

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

Red Lotus has already sorted out the data.

Comparison based on actual tests.

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

It's not much, it's just a difference of 0.03 kg in thrust.

This is completely negligible for a solid rocket engine, since in general, the missile destroys the target before it runs out of fuel.

So this difference is nothing at all.

Afternoon.

Tang Rui happily returned to the company.

The main reason why he is so happy is that this engine was completely designed by himself.

Red Lotus only used it as a calculation tool to aid the design, and did not participate in any modifications.

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.

It's a very different feeling.

"Red Lotus, let's produce ten missiles first, and then use this engine I designed."

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

"Okay, master, the manufacturing has begun, and it is expected to be completed in the early hours of tomorrow morning."

Buzzing......

Just as Tang Rui was about to say something, his mobile phone rang.

It was Lin Chao's call.

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

If it's okay, Lin Chao won't call him, and if it's not urgent, he will tell him when it's time to eat.

As long as it's a call, it's urgent.

"Mr. Tang, the police contacted me just now and said that the Skynet drone you sold to the police has set up a ban on flying at the national border."

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

Tang Rui thought for a while, nodded and said.

When he set up this program, he was afraid that the image algorithm would be exposed.

The image algorithm of the Skynet drone is not the version he sold to Huawei, although it is not a complete version, but the processing ability of the image is already very good.

If this algorithm is obtained abroad, it is not a leak.

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

Normally.

This sequencing is not activated.

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

"That's right...... I see, I'll explain the situation to the police. After Lin Chao listened, he was about to hang up the phone.

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

"That's right, when the funds in the Yun Province area used the Skynet drone to search for a cross-border criminal gang, they found that the other party had run out of the border.

At that time, the police wanted to use drones to track the other party and find the other party's lair.

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

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

It's a joke.

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

Tang Rui's eyes suddenly lit up, and he thought of something.

I'm not in the state today.,It's more than 4 chapters.,The fifth chapter can't be written.,Go to bed early.,At least tomorrow morning.。
