What good will the Americans do? It's just a real job!

Give the gunner an actual target, and use specially produced ammunition to shoot at a simulated attack aircraft with a sturdy body that can withstand the attack of a special warhead, so as to obtain the closest training effect to the actual combat. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

After pitching his ideas in the office, Lin Jun soon found that it was easier said than done.

First of all, there is the problem of ammunition: that is, it is necessary to have a certain muzzle velocity and control the power, so as not to pose a threat to the "target aircraft", and the warhead material also needs a new design, preferably to be shattered with one hit.

Ammunition is easy to solve, experts can quickly figure out a solution, the bigger question is what aircraft to use for the role of "enemy aircraft": the Soviets now do not have a single model of aircraft suitable for this role.

The Americans had the P-39, but now the USSR did not.

The last question is whether it is worth it: the idea is good, but Lin Jun remembered that only the United States seemed to have done it in history. The advantages of conducting simulation training are obvious, you can accumulate experience in shooting at high-speed targets in the air, and at least you will not fight like Lin Jun's "gunners" in the sky.

The Americans have a lot of money and can do everything, but there is no other country to do such a project -- there is no time, and resources have to be used in more important places. The Americans can train in all directions, and it is obviously the only one who has this condition.

If the standards set are the most advanced and most in line with the requirements, it is good, but if they do not conform to the actual national conditions, the side effects outweigh the benefits.

Lin Jun insisted on forming a simulated army all the time, and the results would be very good, but once the war started, the gains might outweigh the losses -- the consumption of ammunition and fuel, and the dispersion of human resources were unacceptable.

So what to do? Hit more targets, the living can't let urine suffocate to death!

Lin Jun likes the airport, and he likes the airport now, which is much more "cute" than the airport in a few decades! There are grassy lawns everywhere, patches of primeval forests in the distance, there are only a few concrete buildings in the airport, and there is only one cement runway, everything seems natural, much more "harmonious" than in the city.

With the familiar smell of fuel and the ever-busy crowd, the airport is a sign of the country's dynamism. There is only one small town near this research site, and there is no hustle and bustle of the city, which is best suited for the testing of aircraft and avoids unnecessary leaks.

No matter how secretive the Soviet Union is, there will always be a very small number of foreigners passing by in the big cities, and that kind of trouble can be avoided here.

This trip to Lin Jun not only inspected the bomber base, but after lunch, he and his attaché boarded two more Li-2s, and the destination was Gorky City, 350 kilometers east-northeast.

Polikarpov was still with Lin Jun, but this time the plane designer did not know what today's destination was, he only knew that the plane would land in Gorky in a little more than an hour.

"Polykarpov, how much do you know about our new aviation technology?" Lin Jun asked the designer next to him on the seat.

"It's hard to say, I basically know about fighters and bombers, but I definitely don't know as much as you."

The designer makes sense – he knows everything he can know.

"Don't put any secrecy in front of me, I want to hear your opinion." Lin Jun knew that this guy was playing haha.

"Well, I've seen the Omeca III and IV helicopters of the Bratuhei Design Bureau, and the new aircraft can do some auxiliary tasks now, but it should have a good future. ”

"I have already given additional funding to the Moscow Aviation Institute to continue the research of Bratukh and his design team (Bratuhe, a famous early Soviet designer of rotorcraft and helicopters, who led the design bureau under the jurisdiction of the Moscow Aviation Institute)."

"I've heard about this, and you've dug up a couple of budding designers in rotor research, and I'm optimistic about Nikolai Ilyich Kamov and Mikhail Leonkiyevich Miri, who are very driven and talented."

"How do you know everything?" Lin Jun didn't expect that Polykarpov knew a lot.

"The Aviation Commissioner has my office, Andrey, within the purview of the Confidentiality Regulations."

"Huh."

Porykarpov was a member of the Aviation Committee and knew none of this.

"We can't expect those planes to win the war, it's all about preparing for the future after the war is over. Polikarpov, today we go to an institute on the outskirts of Gorky, where research is beyond your level of secrecy. ”

The designer shrugged his shoulders, with Lin Jun in his hands, he could go anywhere.

"You've probably heard about that research project, but the news there has been kept strictly secret for the past two years." As he spoke, seeing that the designer still looked indifferent, Lin Jun was a little unhappy: "I said old guy, you can't satisfy my vanity, and ask a little curiously, what is the research there?" ”

"Secrecy regulations, besides, you will definitely tell me in the end, otherwise you won't want me to get on the plane, why should I take the risk of asking."

Facing the rogue and stable designer Lin Jun had no problem at all, he felt like a boring person talking to himself just now.

"Okay, there's a brand new aero engine working on there, jet propulsion."

"Where is Comrade Rurika?"

"Yes, Alhep Mikhailovich Rurika now heads that institute, and for two years he has achieved a certain amount of results."

"I was in the middle of a test from Vladimir Vasilyevich Uvalov (the leader of early Soviet turbine engines. The engineer knew about Rurika's research. ”

"When?"

"At the beginning of 38, I also went to the meeting of gas turbine experts in Moscow as an observer. Ryurika was supposed to be doing research at the Kharkiv Aviation Institute, and he had a design that Uvarov would suggest. Later, Uvarov and I talked about it, and it should be the jet engine you talked about. ”

"Now Ryurika is no longer in Kharkov, just in Gorky, and half of the jet engine designers from the whole Soviet Union who I arranged are doing research there."

Now that Lin Jun was talking about one of the core secrets of the Soviets, the main aircraft designers of the design bureaus knew that various new engines were being studied, including jet engines and rocket engines, but the details were not clear. Lin Jun wants to combine the two departments to avoid waste of resources.

There are now two places throughout the Soviet Union where different types of jet engines are being studied, including the most technologically mature centrifugal type, and the turbojet, ramjet and turbofan type.

In his previous life, Lin Jun was a Su-27, but unfortunately he was only a pilot, not an aero-engine engineer. In fact, even engineers are useless, those processes that appeared decades later are not what can be solved now, and a high-tech engine involves almost all the high-tech industries of a country, not a few people can build it.

Fortunately, the Soviet jet engine, no matter what type it is, has not been poor in 40 years, and it is not at all the same as later generations of the West slandered that it depends on German and British technology. The appearance of Lin Jun played a role not only in providing stable logistical support for research, but also in providing reasonable theoretical suggestions to avoid detours.

As a fighter pilot with solid basic skills, the working principle and basic structure of jet engines are a course that must be mastered in the cadet era, and the air forces all over the world are the same. Decades later, the usual common sense can be said to be a gift from heaven to the current engine designers, so Lin Jun once recalled all the common sense and simple construction drawings of jet engines in his memory and handed them to Gorky's designers.

Many theoretical problems that cannot be solved academically can be solved by unusually simple drawings, at least there is a direction to work towards. In Lin Jun's original plan, the jet engine was not prepared for now, but after the war. But apparently the designers are moving faster than they expected - they have already built an engine with a thrust of 800 kilograms, which is almost at the practical stage.

This brought Lin Jun's plan forward, and at least 45 years ago, there would be a relatively practical jet testing machine.

"This time I didn't take you shopping, I asked you to design a twin-engine experimental jet fighter, these are the materials."

Polykarpov will soon be an idler, and the Peter-8 is just his side hustle, and this veteran and powerful designer Lin Jun should make good use of it.

Limited to the process constraints of the past two years, it is impossible for the Soviets to get engines with a thrust of more than 2,500 kg, which means that the MiG-15 and 17 on Lin Jun's drawings can only be drawings. But the experimental model that can produce a single 800 kg thrust is a milestone, and if it is a twin-engine configuration, it will at least allow the aircraft to fly and accumulate valuable experience.

Polykarpov was fascinated by the fact that this was obviously a completely new field that he had never touched before, and a new challenge.

But he didn't start from scratch either, "Andrew, you designed this outline?" ”

"Yes, I have asked the Moscow Aviation Institute to do a model wind tunnel test, absolutely no problem, all you have to do is the internal structure design and install the two engines, of course, you still have the right to modify the necessary shape, haha."

If Dr. Mercedes was here, of course, a doctor a few years later, he would definitely scold Lin Jun for being shameless: the plane on the drawings was simply a copy of the Mercedes Smitt 262.

With a thrust of 800 kg, the design of the Mercedes Smitt 262 is the most suitable carrier aircraft, and Lin Jun certainly has to steal it. I didn't expect it to fight an imminent war, for the sake of accumulating experience.
