Chapter 1844: We come to process

Qin nodded his point of view. This young man stood out in later generations and became the chief instructor of the entire design bureau. Under such difficult circumstances, it was definitely not easy to bring Jacques Design Bureau out. Leng was relying on the trainer to survive.
Now, this young man immediately saw the crux of the problem, which is the drive shaft.
Fighters in World War II had their engines placed in front of their noses. This resulted in a very large nose. The pilots were almost behind the aircraft, so the pilot’s vision was quite poor. Why not put the engine behind? ?
If it is placed at the back, there is also room for the cannon on the nose, which is definitely more convenient than the cannon on the wing.
In fact, it’s not that you don’t want it, but you don’t have the ability. If the engine is placed behind, then a drive shaft is needed to extend from under the pilot’s seat to the nose.
This drive shaft is often thousands of revolutions and tens of thousands of revolutions, and it is also a few meters long. The transmission power is thousands of horsepower. The material must be quite strong, and the processing accuracy must be quite high. strength.
The Eagles created the monster P-39 fighter. When other fighters had a big head, it had a sharp mouth because its fighter was behind.
Of course, this alternative fighter has made many pilots complain about it. For example, the cockpit is actually a way of car doors, parachuting is extremely inconvenient, etc., but in the hands of Xiong Guoren, this fighter has played a huge role and was born. There are several ace pilots from Xiong Country.
It was only a few thousand horsepower back then, what about 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 aircraft engine is modified to be the gas turbine of the warship.
Look at how thick and heavy the drive shaft of a warship is, but it's not good for airplanes. The space inside the aircraft is limited, and its drive shaft cannot be very thick or heavy, so it needs high-tech materials. In order to suppress its vibration, it also needs high-precision processing capabilities.
This kind of ability is what Xiong State lacks most.
You can also compare the F-35 lift engine. This is a cylindrical object. In fact, the lift fan is on the top and has a two-stage forward and reverse structure. The diameter of this fan is 1.27 meters and the maximum air flow is At 227 kg/s, it can generate 81.8 kN thrust, which is almost a perfect replacement for these two lift engines. The whole body below is cylindrical, but it is actually empty, it is only a passage of air, so the overall weight is also Not big.
When the rear cover is opened, you can see this lift fan.
The lift fan only works during take-off and landing, so a special clutch is needed to connect to the main engine. This is also one of the difficulties. The drive shaft is along the axis of the aircraft, while the lift fan is vertical. In the straight state, transmission gears are also required. These are difficult points, which need to withstand fairly strong power.
This entire shaft drive system requires extremely high reliability requirements. It is a severe test for bearings, transmission gears, lubrication, etc. In short, you can't make mistakes. Any small component failure may cause a crash. In contrast, the lift engine has to be better controlled. Even if one engine is broken, it can be maintained by another engine.
Now, without writing to calculate, just thinking about it, Dongdukov has already thought of the key to the problem, and put it out, at least they Xiong Guo does not have this processing ability.
"I think you should have this kind of high-strength material, and we have the processing ability." Qin Guan said: "You provide the material, and we are responsible for processing, so that it can be solved perfectly."
You can't, we can.
In terms of materials, the bear country is not bad. This is to examine the basic industrial level of a country. The bear country is strong in this respect. Their dilemma is processing. They don’t have this kind of processing capability. Let's process it, the two sides work together and it will be done naturally.
Of course, Qin Guan was deliberately fooling around. If this is the case, he has entered the Jacques 141 development team. How to make this drive shaft requires joint research by both parties, and this thing is connected with the engine. , In this way, all the technologies are in it.
In fact, the technical content of this drive shaft is still quite high. The current Han country may really not be able to handle it, but Qin Guan has a system anyway, as long as the processing technology on this drive shaft is taken out of the system. Now, when the time comes, it will be handed over to its own research institute, or even to Heribala for research. With Sandra, it will definitely be possible.
And now, his proposal has already touched the other party.
The Yakleev Design Bureau has been studying this lift engine for many years. It can be said that it is a light vehicle. It is said that it is safer to continue this route. However, in this case, the problem of smelting the deck is always unsolvable and cannot be recognized by the Navy. , And Qin Guan said that the lift fan method is really a good solution. It can be solved with one engine, and the problems of fuel consumption, self-weight, and so on are all solved.
Handling the processing question to Han Guo?
"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 aircraft out as soon as possible. After the finalization, we Han will also buy about 30 to 50. "Qin Guan said.
Han Guo already has orders, so it’s more secure. Han is now operating those Yak-38s, and has also realized the role of this kind of fighter, especially on the southern islands and reefs, which can be used as a take-off and landing platform at any time to control the sea area there, which is quite convenient and quick.
In fact, as far as the fighter aircraft manufacturer in the country of Xiong is concerned, the number of aircraft is often hundreds, or even thousands or tens of thousands. These dozens of aircraft are not worthy of their eyes, but this is Yakerev. The design bureau, their design bureau, they can get a regional airliner with a production volume of thousands. As for fighter jets, the previous Yak-38 has a total of less than 100. For a design bureau that developed fighter jets In terms of it, this is definitely a shame.
Now, if this type of Yak-141 is produced, then Han will order dozens of them. This is definitely a big deal. This stimulates them. Shuchikov immediately nodded: "We will Set up a branch to study the feasibility of this kind of scheme. So, Dongdukov, you can participate in this project. You are already very talented in the Mikoyan Design Bureau. We can safely hand over this project. You do it."
