Chapter 1049: 4S standard

Reform and opening up means to change concepts. In the Air Force, concepts must also be changed. Only in this way can we win future high-tech wars. We must take this seriously.
Maybe it's not very touching now. When next year, the terrible naval battle should open the Navy's eyes?
"I will then introduce you to the fourth-generation aircraft. The first standard is stealth, and the second standard is supersonic cruising."
Supersonic cruise is not difficult to understand. Ordinary fighter jets can fly at supersonic speed, but all of them can reach supersonic cruise after turning on the afterburner.
When the fighter is turned on afterburner, the fuel will be consumed rapidly. If it can normally fly for two hours, after turning on the afterburner, the fuel will run out in ten minutes.
Therefore, the afterburner flight is only a special case. It will only be turned on when you need to take off quickly, climb quickly, and fight air combat. No pilot will keep flying with afterburner for no more than three minutes each time.
In this way, supersonic flight is actually tasteless.
If a fighter jet can fly at supersonic speed without turning on the afterburner, it will undoubtedly be of great benefit. For example, it can quickly rush to the battlefield without flying slowly like other aircraft. For example, it only needs Fly away at supersonic speed, then it will be separated from close combat, and the opponent will not be able to catch up.
It is useless to pursue extreme speed. For example, the F-22 of later generations has a maximum speed of Mach 2, but people can fly to Mach 1.5 without turning on the afterburner, which is beyond the reach of opponents.
Qin Guan said that with this second criterion, the people present were taken aback, but with the situation just now, everyone did not express opposition, but the expressions on their faces were the same.
Impossible, impossible, isn't this alien technology?
"We lag the most in engine technology, so this technology is somewhat difficult to implement." Qin Guan said: "But this indicator must be one of our directions, specifically, to increase the maximum military thrust of the engine."
The thrust of the engine has two indicators. When the afterburner is not on, the maximum thrust is the maximum military thrust, and when the afterburner is on, it is the maximum afterburner.
If the afterburner is not turned on, the thrust is sufficient, so it will naturally be able to cruise at supersonic speed.
The principle is simpler than the first stealth. However, this engine consumes the most industrial base. Without a strong industrial base, it can't be done.
This is even more difficult to achieve.
Although it seems difficult now, this goal must be achieved. This is Qin Guan's opinion.
"To reach this standard, the thrust-to-weight ratio of the engine must reach 10. This is a serious challenge for us. After all, our existing mature engines have a thrust-to-weight ratio of only 6."
The ratio of the thrust of the engine to its own gravity is the thrust-to-weight ratio. The larger the number, the higher the efficiency of the engine, but blindly pursuing this number will bring reliability problems, so it must be handled in a coordinated manner.
At present, the mature engine of Han is the Spey engine. Its thrust-to-weight ratio is only 6, so Niu can export it to Han. As for more advanced engines, this era has been able to reach the order of magnitude of thrust-to-weight ratio of 8. China’s F100, but it is not easy to mature.
As for the thrust-to-weight ratio of 10, there is only the most impressive F119. The development of this engine can be said to be the crystallization of the overall industrial level of the Eagle Country.
To reach this level, Han will have a lot of ways to go.
"Under the current circumstances, if we want to reach this standard, we have to take shortcuts. For example, our duck layout has inherent high-speed advantages. For example, our variable swept wings can also reduce the resistance of high-speed flight. "Qin Guan continued.
Both of these are equivalent to taking shortcuts. After obtaining those technologies of its own, Grumman must also build invisible cats on the basis of Tomcat. I don't know if they can succeed.
"The third thing that has a lot to do with the engine is super mobility." Qin Guan continued to explain: "When our fighter adopts stealth, it will greatly reduce the chance of being discovered by the opponent. It can be said that The opponent can be solved in mid-range air combat, but if our enemy is also a stealth machine, then everyone may not find it until close range, so it enters line-of-sight air combat."
Now, the prevailing high-altitude and high-speed ethos in the world has just passed. I don't know if these people in front of me can accept their opinions, Qin Guan thought in his heart.
However, I have to say everything I know, provide everyone with ideas, and slowly correct everyone's wrong views. In short, this is my mission.
Qin watched the crowd. Although their faces were all surprised, they were still taking notes seriously. It seemed that he still attached great importance to his proposal.
"In close combat, the stronger the maneuverability, the better. At this time, it is not enough for the fighter to rely solely on strong power. It must also have vector propulsion capabilities. The vector nozzle brings super mobility."
The vector is the direction. That is to say, the direction of the engine tail nozzle can be changed. This is not an innovation. For example, the Harrier fighter can deflect the nozzle downward, but it is only used during takeoff and landing. What Qin Guan said could be operated at any time during air combat.
After the vector nozzle is installed, the maneuverability of the fighter will change drastically. It can be said that if a fighter without vector nozzles competes with a fighter equipped with vector nozzles, as long as the pilot does not make mistakes, there is almost no chance of winning. This nozzle alone is also very advanced in technology. If it cannot be matured, it will not be practical. If the life of the nozzle is only a dozen hours, it is like the pitted Su-30 of Bai Xiangguo. With the vector nozzle, It's almost like nothing.
"These are all new tactics, and they also require the research of the Air Force's theoretical researchers." Qin Guan said: "The last one is advanced avionics technology."
"When we adopt the hot-line aiming of the cannon, we can feel the technological progress. When we can use the airborne radar to lock the target, we will know how much avionics technology has improved combat effectiveness. In the future battlefield If there is no breakthrough in airborne avionics technology, then we will not be able to achieve victory in air combat."
These are the four basic standards of the next four generations of aircraft. In Eagle words, each one starts with S, so together, it is called the 4S standard. Only if these four standards are met, then it is a model. The out-and-out fourth-generation machine.
Because some planes can't reach it, and in order to put gold on their faces, they position themselves as the 3.5 generation.
