Since I Was a Special Soldier

　　 Having nuclear power does not mean that there is no need for an engine. It is just that the turbojet engine behind it will be redesigned. Fuel is no longer provided for fuel combustion, but nuclear reactors.

　　 This reactor is naturally a fission reactor.

　　 "Does it have any advantages? How long can it fly if it is refueled once?" Jiang Yanhai asked a key question.

　　 Although everyone knows that nuclear power uses a very small amount of fuel, the nuclear power itself is a very small reactor, which means that its critical core cannot contain too much nuclear fuel even if it is placed in it.

　　 "It has a flight range of about 100,000 kilometers with one refueling." Professor Hu gave a specific number.

　　 Jiang Yanhai took a deep breath, 100,000 kilometers, this number is already extremely terrifying, and the equator around the earth is only more than 40,000 kilometers. This means that you can go around the earth two times more.

　　 This is no longer a matter of combat radius, which means that it can even fly without changing fuel for a long time. As long as the life of its tail turbojet engine can last, it can even stay in the sky.

"Can it go into space?" Jiang Yanhai re-estimated its data in his heart. Whether it can go into space mainly depends on how high it can use air. If the utilization rate is high enough, even after the plane leaves the ground for a certain height The air will become very thin, but at that time, as long as the power is strong enough, flying out should not be a big problem.

　　 "It is difficult at the moment, but this is our goal, but according to our current data, although it cannot fly into space, its maximum flight altitude can reach a super high altitude of about 60,000 meters."

60,000 meters, which is 60 kilometers from the ground. This altitude has exceeded the flying altitude of all existing fighter jets. Even some intercontinental missiles are capable of flying above this altitude. Common interceptor missiles, anti-aircraft missiles, and air-to-air missiles None have this ability.

Jiang Yanhai estimated it in his heart. In fact, if all the parameters are corrected according to the data analysis system, it can actually barely fly into space, but after flying into space, its internal fuel is basically exhausted. Landing must be a problem.

　　 But compared to the previous aircraft, this is really a huge improvement.

　　 "What about the speed of the plane?"

　　 "If a brand-new composite material is used, it can reach a cruising speed of Mach 4.5 and a maximum speed of Mach 6, but it needs to be reached at a super high altitude." Professor Hu gave a number.

　　 "Have you found the material to solve the thermal barrier?" Jiang Yanhai was really surprised this time. Human fighters have never been able to break through Mach 3 or more. Before the Phantom came out, it was because the thermal barrier was not so easy to solve.

　　 When the Blackbird reconnaissance plane broke through Mach 3, its overall length could even increase by more than 20 centimeters. It is conceivable how terrifying the thermal expansion and contraction of materials are.

The Phantom solves this because the expensive ultra-high temperature resistant material on the fuselage has reached a certain level of resistance to high temperature, so that after reaching such a high cruising speed, the thermal expansion of the fuselage is controlled within a certain range. Inside, the parts will not deform too much.

　　 But after exceeding Mach 3, it can be said that the speed increases by Mach 1, and the temperature increase is even more dramatic. At least the original material of the Phantom cannot withstand the cruising speed of Mach 4.5 and the limit speed of Mach 6.

　　 "I found it. When it comes to this, I have to say, Xiao Jiang, you are this." Professor Hu gave Jiang Yanhai a thumbs up directly.

Several other professors also looked at Jiang Yanhai with admiration, "In fact, we discovered this material before. It is a composite material combined with new materials from Daqin and Red Star. We found that it has extremely strong resistance. At high temperatures, the coefficient of thermal expansion is the same as some ceramic materials, infinitely close to zero."

　　 "Of course, these two points are not enough. It also needs to have other characteristics that can be used as a fighter material."

"However, we have never found the most suitable formula, because there are too many new materials, and new materials are discovered almost every day. The data recorded by the Materials Research Institute in this regard, the newly added data in the last month exceeds them. Data added in the previous year."

　　 "If it weren't for the Pangu system, we don't know how long it will take to find it."

　　 "Because of the Pangu system, we have solved the problem of this new material in a very short time, so we have these demonstrative next-generation Phantom upgrade plans." Professor Hu said.

Jiang Yanhai smiled and shook his head and said, "I just provided the tools, but in fact, it is you who have actually completed it. Even without us, you will still complete it in a very short time~www.readwn.com~ However, I Before I came, I heard from Professor Liu, do you have other upgrade plans?" Jiang Yanhai was a little curious.

　　 There are two upgrade plans for the next generation of the Phantom, which can be said to be one of the two.

　　 Before coming, Jiang Yanhai didn't know both plans.

　　 "Yes, the second plan is still conventional power." Professor Hu nodded, "but thanks to the application of new materials, we have upgraded the Phantom engine."

"The main thing is to improve its fuel efficiency. With the current fuel load of the Phantom, its range has increased by more than 50%, and the turbojet efficiency is higher, and the power output in a short period of time is higher. In addition, We also super-pressurized its compression chamber." Professor Hu said quickly.

　　 "Now it has a smaller volume and a smaller nozzle, but it has more power."

　　Jiang Yanhai immediately gave Professor Hu a thumbs up. Generally speaking, when the gas speed of a fighter jet engine passes through the tail nozzle at a certain speed, the larger the nozzle diameter, the greater the thrust.

　　 Of course, the nozzle diameter can be adjusted. Different flight attitudes use different nozzle diameters, and now they have actually made a smaller nozzle diameter in this regard.

　　 In fact, to put it bluntly, the reason for this is that our materials did not pass the test before, but now our materials have passed the test, and even the material performance has great redundancy, then the ultimate performance of the material can be squeezed.

　　 Compresses the air harder, even if the diameter of the nozzle is reduced, the jet speed is faster than before! The thrust will naturally increase as well!

　　 And all of this is based on materials...Without strong enough materials, nothing can be done.
