For vertical takeoff and landing fighters, the most dangerous is the takeoff and landing phase.

Ordinary fighter planes are also dangerous to take off and land, but they are not so dangerous. During vertical take-off and landing, the jet downwards push the fighter plane up, and then the nozzle backwards and slowly turns into level flight until it accumulates enough speed , Let the lift generated by the wings of the fighter balance the gravity, so that the engine only provides thrust. During this process, problems will occur at any time. If a nozzle does not provide thrust as planned, it may overturn the aircraft. , A crosswind blows over, which may disrupt the balance of the aircraft, etc.

Therefore, this kind of time is the most dangerous. In this kind of time, the pilot needs to concentrate on operating various switches. For example, the most mature Harrier fighter also requires the pilots to concentrate their energy one by one when taking off and landing. Completing multiple operating procedures, manipulating rudder pedals, joysticks, throttle valves, nozzle angle control, etc., accidents in every complex device may cause terrible consequences.

This is the sorrow of the era of mechanical control, just like a duck layout, only telex can be tamed, and so is the flying wing layout.

When it came to the Yak-141 fighter, the designers had realized the need to simplify the operation. Therefore, it used three-fold digital fly-by-wire control. In this way, the burden on the pilots was reduced and the pilots could use more Energy to complete the takeoff and landing.

However, this is still not enough. After all, it is not smart enough, not smart, and cannot completely reduce the burden on pilots.

By the time the F-35 is reached, it is already fully intelligent. The pilots hardly need to do any operations. Just tell the flight control computer system that I want to take off, and the flight control system can be based on the altitude and weather conditions at this time. Together, determine a qualified thrust plan, and then automatically adjust the thrust nozzle angle, jet and control aerodynamics, and finally realize all aspects of intelligent control of the aircraft.

At this time, the training of pilots is quite simple. This is also the future direction of development. Technology makes people's work easier, so that pilots don't have to take care of those complicated actions, and can spend all their energy on performing tasks.

Qin Guan’s face is serious: “We must fully understand the control laws of the entire take-off and landing process, and write our own flight control system to make the take-off and landing process automatic. This is the most difficult task. If this task If it cannot be completed, the development of our VTOL fighter will fail."

Of course, there is the source code of the flight control system in the huge data exchanged, but this is definitely not directly transplanted.

It’s like turning the Su-27 into the J-11 at the beginning. It is absolutely impossible to read out the control law of the analog system and directly perform digital-to-analog conversion. This is impossible to understand the technology. In extreme special circumstances, it will inevitably encounter When it comes to danger, one must truly understand the technology.

This is also the biggest test for the 6601 Research Institute. After all, they have no complete R&D experience of the fourth-generation aircraft, or even programming experience for fly-by-wire flight control.

Hearing Qin Guan's words, President Gu hadn't spoken yet, and Dongdukov couldn't help but speak: "Mr Qin, do you mean that the engine is also under full digital control?"

If you want to be intelligent, and all take off and land are controlled by a computer, then an inevitable prerequisite is that the engine must also be fully digitally controlled to achieve this powerful ability of flying fire push cross-linking.

Now, Xiong Guo can’t do it. Take the engine control system, they still use the old mechanical control. On the RD33 engine used on the MiG-29 fighter, the engine control system is a suitcase. The equipment is large and small, and on the F404 engine of the Eagle Country of the same level, there is only the size of a book. This is the gap.

The same is true for the R79 engine. Although their Yak-141 fighter has been controlled by fly-by-wire, the engine still has to use ordinary mechanical control, so the take-off and landing is very technically difficult. Now, Han Guo’s vision is very straightforward. , Fully use telex control, this will raise a big level, can the Han people do it?

"Yes, our latest engine uses this kind of control system." Qin Guan said: "This is also a technical difficulty that we overcome. The flight control and engine thrust control are all carried out by computers. Control will also come in."

The fire control system is not difficult. Just transplant the fire control of the four-generation aircraft that has been successful now. For example, airborne phased array radars, such as missiles with built-in bomb bays, etc., can all be transplanted.

"Han's technology is really too advanced. If such an aircraft can be successfully developed, it will be of great significance, surpassing our Jacques 141 many times!" Dongdukov said.

"So, you, and a few people around you, would you like to join us?" Qin Guan said.

The meeting room suddenly became quiet.

We have been cooperating for several years. However, the two parties are not unified leaders. The other party is from the Yakerev Design Bureau, and they are not in the same country. Therefore, it is impossible to say absolutely perfect cooperation. Now Well, Qin Guan invited them to join the 6601 Institute!

Xiong’s scientific and technical personnel have an outstanding advantage. They are particularly capable of system integration. Even ordinary equipment can be integrated together to produce advanced combat effectiveness. The S300 system is the best example. It is clearly inferior to the West. Yes, but when put together, the missiles that come out are even more advanced than the Patriots.

"Mr Qin, do you mean that we left the Yakerev Design Bureau and become a member of the 6601 Institute?" Dongdukov swallowed and asked Qin Guan.

Qin nodded his opinion: "Yes, at the same time, he also left the country of Xiong. In the future, he will have the nationality of Han and become a technician in Han. In terms of treatment, in addition to the salary of the normal research institute, there is a special subsidy. As long as you join, there will be a settlement allowance of 200,000 yuan, and your family can receive Han to live."

Looking at these people, Qin Guan continued, "Of course, there are restrictions, such as observing Han's secrecy regulations, going abroad is subject to strict restrictions, etc.. So, you must think clearly, in short, you If it comes, I can guarantee that you can all become the core personnel in the research and development of our J31 fighter. Whether you choose the Yak-141 or our J31 depends on your own ideas."

Calling them over was naturally for the purpose of attracting people. To tell the truth, Qin Guan really had concerns about allowing 6601 to complete such a project, but with the addition of the people from the Yakerev Design Bureau, he was sure.
