In fact, General Lin has always had high hopes for this training aircraft.

  In the early years, when the old bus had not yet joined, the country began to demonstrate the aircraft in advance, and the relationship with the West was relatively good at that time, so you can also get some engines from below, so the selection of CJ610-8A, JT15D-5, TFE731-2A and other engines has been carried out, among them, the first two are turbojet engines, especially the front engine, CJ610-8A turbojet engine, is a one provided by General Electric, Factory 320 attaches great importance to it and has made many preparations, not only to carry out the matching test of the aircraft air intake tract and engine, but also to manufacture a wooden prototype equipped with CJ610-8A.

  It can be said that if there is no accident, it will match this turbojet engine, but, at that time, General Lin went to inspect and proposed that the endurance of this training aircraft must be greater than three hours, in this way, the backward turbojet engine must not work, it must be on the advanced turbofan engine, after that, it began to turn to the production of TFE731 engine of the United States Garrett turbo engine company, to 1987, the two sides signed an agreement on the introduction of engine technology, in view of the relatively good international environment at that time, The company was generous, providing 3 engines and related accessories free of charge during the development phase, recommending starter generators, hydraulic pumps and environmental control systems to match the engines, as well as providing engine thrust test tools free of charge during the flight test phase of the aircraft.

  And now, this kind of domestic training aircraft, equipped with an engine obtained in this way, is no problem for test flights, and subsequent production, it is impossible, exports are not affected, but they cannot be used for their own use, if they are used for their own use, then what should they use?

  "The Soviet Union has an AI-25TLK small engine, weighing only 350 kilograms, thrust-to-weight ratio of 49, although this engine is a product of the Soviet Union's sixties, but it is still used in our aircraft, it is still possible, although there is a gap with the current engine, but it has little impact on the basic performance." Shi Lao said.

  Looking at the whole world, when the West closes its door, the Soviet Union is left, and the Soviet Union itself has its own trainer aircraft, and there are similar engines, and the only thing that can be used by itself is the Soviet Union, which was the engine of the sixties, which is better than nothing.

  General Lin nodded: "Yes, it seems that we can consider it from the Soviet side, and if this engine can meet our needs, we can also imitate it." ”

  Hearing General Lin's words, Qin Feng couldn't help but be speechless, it is imitation again, our current domestic scientific research strength in aero engines must not have the time and energy, even if it is the technology of the Soviet Union in the sixties, it also needs to be tackled, but if it is in the future, the turbofan ten is successfully developed, and the domestic economy has also developed, it should be no problem, right?

  "Yes, I hope that the next time we go to communicate with the Soviet Union, we will examine this engine, after all, our domestic air force also has this demand." Shi Lao said, of course they are in a hurry, you know, it takes a lot of effort to match an engine, the matching of the air intake, as well as the control system, various pipelines, the size of the engine compartment behind, etc., must be matched in place, and now you have to do it.

  General Lin nodded: "This is no problem. ”

  Qin Feng was still walking around the plane, looking at this trainer plane, the appearance was ordinary, but for China, it was just to make up for a gap, and after a few turns, he suddenly remembered, Tingting came here, what is it for?

  Tingting must have been here for several days, so now I am not surprised to see this plane, at the same time, they must have communicated something, if Tingting participated in the project, it is nothing else, except for the stabilization machine.

  Wait a minute! Thinking of this, Qin Feng understood that when Tingting came here, she must have coordinated the three-axis stabilization machine.

  B-1 is just a single-axis stabilizer modified with Jianjiao VI, but it only solves the problem of whether there is or not, achieves a breakthrough of zero, and has no practical value.

  This kind of aircraft needs to be a two-seat structure, front and rear can be controlled, if there is a problem with the telex device, it is necessary to use a mechanical device to take over, the previous Jianjiao 6 is such a purpose, but the Jianjiao 6 is too old, if you change the three-axis telex, then the current Jiao 8, should be the most suitable.

  The cockpit is low in front and high in the rear, both pilots have enough vision, normal aerodynamic layout, the control rate should also be the most ordinary category, the shape of the wing, suitable for all kinds of maneuvering flight, test the control of the aircraft, and, as a training aircraft, there is a vacant space in the nose, which can be loaded with the control equipment of the stabilizer, so this aircraft must be suitable as the carrier of the stabilizer!

  "Looks like we're planning to stabilize this plane?"

  "yes." Gu Tingting said: "Our flight test institute has selected this kind of aircraft as our air laboratory, but now the official engineering modification has not yet begun, I came this time, just to understand in advance, to enter the project in advance." ”

  With the success of the B-1, the test flight institute is already eager to try, and began to develop the next generation of aircraft, this kind of project is led by the test flight institute, and once the development is successful, it is also meaningful to the domestic military aircraft research and development. For example, in the future, domestic military aircraft can match these developed digital telex equipment, without spending huge sums of money to buy from abroad, the test flight institute will not only test the fighter jet, but also will be developed in relevant departments.

  Qin Feng heard Gu Tingting's words, and immediately nodded again and again: "Yes, we should have engaged in this kind of air laboratory a long time ago, with this kind of equipment, we can also train our own test pilots in China." ”

  Air laboratory, on the one hand, is to develop various technologies, on the other hand, is to train test pilots, with this kind of air laboratory, then you can input the control rate of the fly, and then let the test pilots themselves to experience, where there is a problem, how to improve, advanced foreign institutions, can make such a way, but the domestic is not good, there is no normal training mechanism for test pilots in China, everyone is relying on enthusiasm to test flight, in the test flight, encounter danger, but also with enthusiasm to resolve, To talk about systematic training, it has not yet begun.

  The West has special aircraft of this kind to train test pilots.

  "We are still discussing the training of test pilots with the Soviet side, and it is estimated that it will not be long before we can send people to the Soviet Union for test flights." General Lin said beside him: "When the time comes, the two of you will have to live separately again." ”
