Not to mention the software, as far as the hardware is concerned, the test flight institute is still engaged in it, the operating lever should be replaced with an electrical signal sensor, the servo behind it should also be electric, and there must be a lot of circuits, just one-way, they are very laborious, and now, Mr. Gu said that he wants to engage in this kind of three-axis and four-redundant digital telex, and engage in our own ACT testing machine, it is like ***.

This is definitely not in line with the style of the 601 Institute.

In Qin Feng's fixed impression, the 601 Institute has always sought stability, in the design of their J-13, this line of thinking is the most obvious, everything is for stability, everything else can be given up, they are just to be able to achieve, otherwise, it is so ambitious, out of the domestic industrial level, it is impossible to really realize.

But what about now? Do you want to learn from 611 and run forward?

No, I can't.

When Qin Feng said this, Mr. Gu also nodded: "Yes, our domestic technology will definitely not be able to support it now, so if we want to engage in this project, it is best to purchase it." ”

Now, we have a hard-won advantage, that is, the country has been opened, and the relationship with the West has become friendly, and many of the things that we cannot develop ourselves can be solved through outsourcing.

For example, the threat on land is the most severe, after all, there is a terrible torrent of steel from the Soviets in the north, and there were only 59 tanks in the country, even if they were improved 69 and 79, the improvement in performance was limited, and they could not compete with their tanks at all.

It is impossible for one's own tank gun to penetrate the opponent's main armor, but after the country was opened, through several different projects, a full set of L7 105 mm tank gun technology was perfectly introduced, installed on the 59 tank, and immediately had the advantage of penetrating Soviet tanks.

In terms of the Air Force, there are a lot of purchases, Spey is the purchase, Marconi company's avionics are also assembled on the J-7, J-8 wants to engage in digital telex, you can also directly purchase it, this is the fastest way!

Our deal with the Americans to improve the J-8 fighter, which of course will expose all the performance of the J-8 fighter to the United States, but we also keep a hand, because our J-8 has begun to prepare for upgrading, and when it is replaced with a turbojet-14 engine, plus digital fly-by-wire, this can improve the performance of the fighter a lot, so the original J-8 fighter, even if it is thoroughly studied by the Americans, there is no need to be afraid.

This is also a consideration of Mr. Gu, and it can be regarded as keeping a hand, but this needs to continue to be purchased to achieve, and it will take a long time to wait for domestic research.

In this regard, it is not necessary to buy from the United States either, from Europe it is enough.

The United States is too domineering, and if it buys these technologies from the United States, there is no doubt that the Americans will definitely ask for them to be modified, and in this way, although it will reduce their own technical difficulties, they will not be able to keep it secret.

In terms of radar, it is necessary to start from the United States, because only the United States is the most advanced, but in terms of flight control, it is not necessarily.

European countries have long overcome the difficulties of flight control, the Tornado fighter-bomber in the 70s has begun to use fly-by-wire control, after entering the 80s, all kinds of aircraft are using fly-by-wire flight control, so it is most convenient to buy from Europe, and they will not ask for too much.

Mr. Gu is here, and for the first time, he proposed it to his superiors, this is purchased from abroad, of course, it still needs to be approved by the superiors, after all, it costs money.

"This is an idea, however, the hardware can be purchased, but the software, we must be cautious." Qin Feng said: "I still think it's a little too hasty, the stabilizer we have developed now has not yet come out, and the software is a big problem." ”

Hardware is one thing, software is another, and it can even be said that software is more important.

The fly-by-wire system is to replace the hydraulic operation with an electrical signal and hand it over to the computer to execute, and the software is very important, specifically, the control rate of the aircraft.

For pilots, the use of fly-by-wire operation, there will be a lot of incredible places, such as the current aircraft, I push the throttle stick, the fighter will accelerate, but if it accelerates, the lift of the wing will be greater, at this time, the aircraft will climb, this is the operation characteristics of the second-generation aircraft.

But when it comes to the third-generation aircraft, I push the throttle stick, just to accelerate, and the plane will continue to accelerate forward, and it will never climb, why? Because the computer has already given instructions, the horizontal rudder surface behind controls the aircraft to climb and keep the plane flying level, so to speak, it is computer-aided to control the aircraft.

The programs are quite important, and they are all dedicated and cannot be mixed.

Just like in the car, there is a very important device called ESP, that is, the anti-slip system, the low-profile car is not, some people say, I buy a car to buy a low-profile, the rest of my own installation, what electric folding mirror, what reversing image, only a few dollars, high-profile is not cost-effective.

These can be installed, but this kind of ESP is impossible to install by itself, because it is a car one by one, the wheelbase of the car is different, the tire model is different, and so on, the data are different.

The same is true for fighters, the procedure for buying back Tornado fighter-bombers is directly brushed to our J-8 fighters, is it possible? Hell if you don't crash.

After all, it is a two-seater aircraft, which can be controlled front and rear, and wait until the software of the aircraft is thoroughly written, and then slowly transfer to the J-8, which seems to be more secure.

This was Qin Feng's inner thoughts, but now, Gu was always very confident.

"Our project will be gradually promoted, we also know that it is not a fat man to eat in one bite, we first introduce technology, and then, in our aircraft experiments, we plan to spend five years to eat it thoroughly and become our own." Mr. Gu said: "At the same time, in order to make the aircraft more maneuverable, we will also add a pair of small canard wings to our fighters. ”

Mr. Gu's report is still continuing, it has already begun, and now, he has talked about technical preparations, if you want to engage in this kind of digital telex, you need to add another pair of canard wings.

Hearing this, Qin Feng became energetic: "Is it movable?" How big of a vortex can it generate? Blown through a wind tunnel? ”

Qin Feng stopped when he said this, and General Lin pulled him: "You don't have to say a few words." ”

This is Mr. Gu's report, it's too rude for you to interrupt him like this, what do so many leaders think, come down and communicate.

Look at it, Mr. Gu's face has changed, you are relatives.
