Super Weapon Swap System

Qin Guan nodded. This young man stood out in the future and became the chief engineer of the whole design bureau. Under such difficult circumstances, it was definitely not easy to come out with Jacques Design Bureau. Leng survived by relying on the trainer.

Now, the young man suddenly saw the key to the problem, that is, the transmission shaft.

During World War II, fighters put the engine in front of the nose, which led to the huge nose, and the pilot was almost in the back of the plane. In this way, the pilot's vision was very poor. Why not put the engine in the back?

If you put it in the back, there is room for the machine gun in the nose, which is definitely more convenient than the machine gun on the wing.

In fact, we don't want to, but we don't have the ability. If the engine is placed in the back, we need a transmission shaft to extend from under the pilot's seat to the nose.

This transmission shaft is often thousands of revolutions, tens of thousands of revolutions, a few meters long, and the power transmitted is thousands of horsepower. The materials should be quite strong and the processing accuracy should be quite high. At that time, only Eagle state had such strength.

The eagle people created a monster like the P-39 fighter. When other fighters top a big head, it is a sharp mouth because its fighter is behind.

Of course, offbeat fighter planes make many pilots Tucao, such as cockpit is a way of car door, parachute is extremely inconvenient, and so on, but in the hands of the bear, this fighter has played a huge role, make complaints about several of the Bear King's pilots.

It was only a few thousand horsepower at that time. Now? This lift engine needs tens of thousands of horsepower! It is almost the same as the power transmitted by the propeller shaft of the cruiser. After all, the transformation of the aircraft engine is the gas turbine of the warship.

Look at how thick and heavy the propeller shaft of a warship is, but the plane can't. The space inside the aircraft is limited, and its transmission shaft can not be very thick and heavy, so it needs high-tech materials. In order to suppress its vibration, it also needs high-precision processing capacity.

This ability is what bear country lacks most.

We can also compare the lift engine of F-35, which is a cylindrical object. In fact, the lift fan is at the top, which is a two-stage forward and reverse structure. The diameter of this fan is 1.27m, the maximum air flow is 227kg / s, and can produce 81.8kn thrust. It is almost a perfect product to replace the two lift engines. The whole below is cylindrical, In fact, it's empty. It's just an air channel, so the overall weight is not big.

This lift fan can be seen when the rear cover plate is opened.

The lift fan only works in the process of taking off and landing, so it also needs a special clutch to make on-off connection with the main engine, which is also a difficulty. The transmission shaft is along the axis of the aircraft, while the lift fan is in a vertical state, and it also needs to drive the gear. These are difficulties, which need to bear quite strong power.

This requires very high reliability requirements for the entire shaft drive system. It is a severe test for bearings, gearbox gears, lubrication, etc. In short, no mistakes can be made. If any small component fails, it may crash. In contrast, the lift engine should be better controlled. Even if one engine breaks down, it can be maintained by another engine.

Now, without writing to calculate, just thinking about it, dongdukov has thought of the key to the problem and put forward it. At least their bear country does not have such processing capacity.

"I think you should have such high-strength materials, and we have the processing capacity." Qin Guan said: "you provide materials and we are responsible for processing, so we can solve it perfectly."

You can't, we can.

In terms of materials, xiongguo is not bad. This is to investigate the basic industrial level of a country. Xiongguo is strong in this regard. Their dilemma is processing. They don't have such processing capacity. Since they don't have it, simply let their own side process it. With the full cooperation of both sides, they can naturally complete it.

Of course, Qin Guan deliberately fooled. In this way, his side will enter the development team of Jacques 141. How to do this transmission shaft needs to be studied by both sides, and this thing is connected with the engine. In this way, all technologies are in it.

In fact, the technical content of the transmission shaft is still quite high. In the current Han country, it may be really uncertain. However, Qin Guan has a system anyway. As long as the processing technology of the transmission shaft is taken out of the system, it will be handed over to his own research institute or even to he ribala for research. Sandra can certainly do it.

Now, his proposal has moved the other party.

Yaklev Design Bureau has studied this lift engine for many years. It can be said that it is familiar with the road, and it is safer to continue this route. However, in this way, the problem of melting the deck can not be solved, so it can not be recognized by the Navy. The way Qin Guan said of the lift fan is really a good solution, With one engine, the problems of fuel consumption, self weight and so on are solved easily.

The problem of processing should be handed over to the state of Han?

"If you think the plan I mentioned is feasible, I suggest that we continue to strengthen cooperation in the later stage and get this kind of fighter out as soon as possible. After it is finalized, our Han country will also buy about 30 to 50." Qin Guan said.

Han already has orders, which is more secure. Han now operates the jacques-38 and also realizes the role of this fighter. Especially on the islands and reefs in the south, it can be used as an takeoff and landing platform at any time to control the sea area there, which is quite convenient and fast.

In fact, for the fighter manufacturers in Xiong Guo, the number of aircraft is often hundreds, even thousands, tens of thousands. These dozens of aircraft were originally ignored by them. However, this is the yaklev Design Bureau, ah, their design bureau. What they can sell is a regional passenger aircraft, with an output of thousands. As for fighters, the former yaklev-38, The total number is less than 100, which is definitely a shame for a design bureau that started developing fighter planes.

Now, if this kind of Jacques-141 is made, the Han country will order dozens of them. This is definitely a big deal, which stimulated them. Shuchkov immediately nodded: "We will set up a branch to study the feasibility of this scheme. In this way, dongdukov, you can participate in this project. You are already very talented in Migao Yang Design Bureau. We can rest assured that you can do this project."
