"Now we have a clear idea of the structure of this aircraft, and it should not be difficult if we build such a fighter ourselves." At this moment, a technician spoke: "This will make up for the lack of the Blackbird." ”

Blackbirds, all made of titanium alloy, expensive and scarce, only about 30 in total, if you follow the idea of MiG-25 and use stainless steel, the number can be greatly increased.

What a spectacle to think of planes with three times the speed of sound everywhere!

However, some people immediately scoffed at his proposal: "How can we do such a thing!" ”

Copycats, shame on people, the United States has the most advanced technology, the Soviets copied the United States, it is understandable, if the United States is allowed to copy the Soviet planes, where will the faces of the technical experts present be placed!

Of course not!

The technical experts present were from various large companies in the development of fighter jets, and they all had identities, and no one could say in front of others that they wanted to copy, and the guy who spoke first suddenly became the target of public criticism.

"I'm just talking, and I don't really want to go to the cottage." That's all the technician can explain.

"Cut!" The others booed one after another.

"Nathan, what do you think?" Emily was amused by the chatter between the technicians, and now she wanted to hear Nathan's opinion even more.

"If it was ten years ago, high-altitude and high-speed, maybe it would be regarded as a research direction, but after we experienced the defeat of the Vietnam War, we should know that blindly pursuing high-altitude and high-speed is not advisable for fighters, and the direction of development is to have excellent maneuverability and sufficient energy, and our new generation of fighters are all developed under the theory of energy mobility." Nathan said: "If I had to choose, I would definitely not choose a fighter with three times the speed of sound, but I would be very optimistic about an aircraft that can cruise at supersonic speeds, for example, a fighter jet can cruise at Mach 1.5 without afterburner." ”

The pursuit of too high maximum speed is useless for fighters, when mounted on a variety of large and small missiles, many aircraft can not fly at supersonic speed, at the same time, due to the supersonic speed to turn on the afterburner, fuel will be consumed sharply, many aircraft can only drive a few afterburner, and then run out of fuel.

If you don't turn on afterburner, you can go to supersonic cruise, that's good.

In this era, aero engines with a thrust-to-weight ratio of 8 are experiencing reliability problems, and engines with a thrust-to-weight ratio of 10 are still far away, so when Nathan said it, those technicians had a sense of fantasy.

Without afterburner, supersonic flight? How perverted is the power of the engine?

"If we can't reach it now, it doesn't mean that we won't be able to reach it in the future, thirty years ago, we were still working hard to break the sound barrier, and now? We have reached three times the speed of sound. Nathan said: "Now we can't reach supersonic speed without afterburner, what about later?" ”

Technology is evolving, and as an engineer in the United States, you should be proud of your technology.

When Nathan said this, everyone present nodded, perhaps, the next generation of fighters, will take supersonic cruise as an important indicator, right?

"Maybe for fighters, too high speed is not needed, well, what about our reconnaissance aircraft?" Graham said: "If we copy the MiG-25, maybe we will have more reconnaissance aircraft with three times the speed of sound." ”

High altitude and high speed may not be necessary for fighters, but for reconnaissance aircraft, this is a magic weapon for survival, and if the SR-71 could not fly like this, it would have been shot down many times.

The SR-71 is valuable, while the MiG-25 is quite cheap, and if a batch of this type of aircraft is produced, it can greatly relieve the pressure on its own reconnaissance mission.

Fortunately in normal times, once there is a war, their 30-odd reconnaissance planes are simply exhausted.

Faced with this question, Nathan shook his head again: "That's not good, in fact, up to now, SR-71 and MiG-25, which can only fly to Mach 3, are not very safe, the enemy's air defense system is constantly developing, even if it can't be shot down now, it doesn't mean that it can't be in the future." ”

In fact, at the final stage of the Vietnam War, the Vietnamese ground air defense forces, with the help of the Soviets, equipped them with the CA-75M anti-aircraft missile system through the necessary corrections, perfected various combat performance, and were already able to destroy high-altitude and high-speed targets similar to the "Blackbird" performance, but the war was over and there was no chance of real combat.

A few years later, when the Blackbird reconnaissance plane flew over the Far Eastern Peninsula again, it was ambushed by the ground, and although the three "Vega" missiles launched from the Wushui Duan failed to effectively hit the SR-71 and only damaged part of the SR-71's body, it was still forced to withdraw quickly, and never dared to fly across the border again.

Again, technology is constantly improving, and now it seems that advanced technology will soon lag behind, just like U-2, when it was a height advantage, the sky was high and the birds flew, but they were beaten down by missiles, because people also have to find a way to deal with you.

The reconnaissance plane, which has three times the speed of sound, now seems to be still advanced, but it will not be long ahead, because the missiles of others are almost enough.

When Nathan said this, almost everyone was looking at him, yes, Nathan's opinion is quite correct, so, how to solve it?

"So, I think that if we want to continue to maintain the superiority of the reconnaissance aircraft, copying the MiG-25 is a repetitive waste of labor, and there will be no progress, and we must pre-develop a new generation of aircraft, which should have a speed of more than Mach 6."

The current Blackbird is about Mach 3, which means that the new flying machine will be twice as fast!

Listen to some people, six times the speed of sound, what are you kidding, how many technical problems are there? If the head of the aircraft rubs against the air, the temperature may be thousands of degrees!

What about the engine? At such a high speed, the existing engine must not be used, it must be a special ramjet engine, but the ground is not good, it must be a variable-cycle combination engine!

There are a lot of technical problems involved.

Only a few people sighed in their hearts when they heard Nathan's words, this Nathan actually guessed it?

Yes, now, there are some rumors at the top of the Air Force that they want to carry out the index design of the next generation of reconnaissance aircraft, of which the speed is, on the one hand, Mach 6 as the standard.

Of course, Nathan is not talking nonsense, he is from the afterlife, of course he knows about the secret project called the Goddess of Dawn!
