Chapter 1445 Unprecedented

Mr. Liu and the others were a little curious about Jiang Yanhai's question. Jiang Yanhai's way of thinking was different from theirs. There were many things that they had never thought of before Jiang Yanhai raised it.

"What design?" Professor Liu, Professor Hu and several other experts in fighter design were curious.

Speaking of which, although the Phantom was designed by Jiang Yanhai, but because his own tasks are relatively heavy, some small details and minor problems of the Phantom are usually improved by these professors.

Of course, when they improve the Phantom, they are also constantly learning, and these professors know this well.

Not to mention anything else, just say that many designs of the Phantom have never been thought of before.

And now that Phantom has started the research and development of the next generation, they also came here with a learning attitude.

Although they are all Jiang Yanhai's uncles, or even grandparents, they are still lacking in design.

"It's like this. You have all seen the performance of this new material. It is resistant to high temperature, thermal expansion, and it can also actively absorb radar waves. It is similar to the existing composite materials. The most important thing is the other several behind it. performance."

"When these properties are combined, the plasticity of this material is very strong, so I have an idea that now the speed of the Phantom is not limited by the engine, but by its material."

"So, have you ever thought that if its shell is all made of this material, we can integrate thermoelectric power generation and thermorefrigeration inside it." Jiang Yanhai expressed his thoughts.

Temperature difference power generation... Everyone was stunned for a moment. Generally speaking, this thing has nothing to do with fighter jets.

Did you say fighter jets need electricity? This is of course necessary. For example, power is needed to start an engine. In the past, some fighter designs could not even start the engine independently, but needed a ground power supply vehicle to start it. In other words, almost all modern fighters, unless necessary, in the Ground engine driving is to use the ground power vehicle.

When the engine is successfully driven, it will switch to the internal power supply. Of course, it does not mean that fighter jets do not have the ability to self-start the engine, but for safety reasons, as long as it is not an emergency mission, they will use the ground power supply vehicle.

The power consumption of the electronic equipment of each fighter is extremely terrifying, whether it is a high-power radar or various other electronic instruments.

Like the J10's interior is also equipped with a fuel cell as a backup power supply.

There is no way to do this, after all, the power of the engine is sometimes very tense.

However, the current solution, there is no solution, is to use the engine to drive power generation and then supply electricity to use electronic equipment.

If the power of the fighter is sufficient, then it has other options. For example, its fuel consumption will definitely be reduced, and the fuel consumption will be reduced, and the combat radius will naturally increase.

However, the previous fighter jets, apart from the nuclear power just proposed, could not have other power generation methods, but now, Jiang Yanhai said, when these old professors contacted this new material, they all felt that this matter ... have a trick!

Temperature difference power generation, as the name suggests, is not like the traditional way of using heat to generate electricity. The traditional way of using heat to generate electricity is simply to boil water.

Including nuclear power plants, etc., boil water, and thermoelectric power generation directly uses the temperature difference of materials to directly convert heat energy into electrical energy.

However, the efficiency of thermoelectric power generation is extremely low. The previous materials are only about 6%. According to different materials, it is about 3%-10%, but most of them are about 6%.

Thermal power plants have different thermal efficiencies according to different technical levels, but most thermal power plants have a thermal efficiency of around 40%.

In other words, 60% of the heat is consumed in the process of generating electricity.

Not to mention the power generation methods of temperature difference power generation.

But that was before, thermoelectric power generation mainly depends on the material, and this new material can increase the thermal efficiency of thermoelectric power generation to more than 20%.

About 20%-25%, this efficiency is already extremely terrifying.

You know, this is at least three or four times more efficient than before!

More importantly, if the new generation of Phantom uses conventional power, its cruising speed can reach Mach 4.5, so the cruising speed of Mach 4.5 means that the temperature outside the body will be about 500-600 degrees Celsius, and the surface of some parts of the body The temperature will exceed 600 degrees Celsius.

Such a temperature is all for nothing. If such a temperature is used for thermoelectric power generation, not to mention how much it can generate, at least it is a huge supplement to the power of fighter jets.

Because when the time comes, the Phantom will probably be supersonic. You think, the normal cruising speed is above Mach 4.5, and the normal flight speed is estimated to be supersonic, and some missions performed by the Phantom are estimated to be far away due to its combat radius. Combat at a distance.

It is a good thing to save energy in such operations.

And in the process of thermoelectric power generation, heat is consumed, and if possible, thermoelectric cooling can be combined.

This is equivalent to improving the high temperature resistance of fighter jets during flight, and the cockpit environment where the pilot is located will also improve.

"We can experiment with this. If possible, it will have a huge role in aerospace, especially for the return capsule, and the return space shuttle, rocket, and even the power supply method of the satellite that we will cover later. Waiting is helpful." Professor Liu and the others took a deep breath.

They also didn't expect that Jiang Yanhai came up with such a new material not long after he left. Although this is calculated from the research results of the Materials Research Institute, it is still a new material. ,

Because the performance and properties of materials have undergone tremendous changes, it is not an exaggeration to say that they are completely different.

"Then trouble some professors. I may not have much time recently, but I think this material has great potential. In addition, they seem to be using this material in the research of controlled nuclear fusion, but I think the material they used The material is still not optimized, I will try to calculate it." Jiang Yanhai made a bottom line first.

"Don't worry, we will leave these matters to us. I really don't know what to say about you. I feel that you can do everything. If you can really optimize it, then we might not be able to completely solve controllable nuclear fusion." Professor Liu and the others also became serious.
