Super Weapon Swap System

"Of course." hearing Qin Guan's question, old Lu immediately explained to Qin Guan: "For example, the radar in front of it has begun to use our latest phased array radar. Of course, because this is No. 1 aircraft, which is ready for its first flight. It is not equipped with radar equipment and is replaced by counterweight. However, the future No. 3 and No. 4 aircraft will certainly be equipped with this kind of radar equipment that enters first."

For the Han country, the most advanced is electronic technology. Now, the Han country has successfully developed early warning aircraft and air defense aegis ships. They are all using domestic phased array radar system. Similarly, this radar can also be transplanted to fighters.

In this era, MiG-31 also began to switch to phased array radar. Through this new type of radar, fighters have stronger detection ability. However, MiG-31 is a passive phased array radar or a centralized launch mode, but a phase shifter is added in front. In Han Dynasty, it is already a phased array radar composed of separate T / R units!

With the progress of technology, the volume of the new generation of units has come down, which means that it can accommodate more units and achieve stronger detection capability. In this regard, Han has reached the most advanced level in the world.

Phased array radar is the only way to find stealth aircraft. In later generations, if you don't go out with a phased array radar, you'll be embarrassed to say hello to others. Now, even the eagle country with the most advanced technology has not been completed. The Han country has already made it. Qin Guan took the electronic system as the breakthrough direction and led the military development through the development of civilian chips. This road has been completed Come out.

Now the first flight fighter is useless, because the first flight is mainly to verify the performance of the whole machine, not the avionics, so it is a counterweight.

"In addition to the improvement of fire control radar, another major difficulty in the development of this aircraft is its integrated flight fire propulsion system." Lu said: "this is the core and soul of the fighter."

Hearing this, Qin Guan was even more excited.

The prototype male cat fighter only uses hydraulic control and computer control on the variable swept wing. However, later, among the jian-11 fighter improved in the Han Dynasty, it has been fully transformed into a three-axis four redundancy digital telex. This system, combined with the variable swept wing, has greatly improved the mobility of the fighter, and now it is moving forward again One step, flying fire push integration!

Qin Guan was clear about this concept.

In the era of three generations of aircraft, the Telex system only operates flight control and controls the flight of fighters. In addition to the flight control system, fighters also have fire control system and power system, which are relatively independent.

The fourth generation aircraft is to integrate the control of fire and power systems to form this "flying fire push" integrated avionics control system.

What are the benefits?

For example, when the radar system finds an enemy aircraft, it can inform the pilot how to maneuver. When it is locked, it can even directly operate the fighter to complete the snake maneuver and get rid of the radar lock of the other party. The flight direction is absolutely accurate.

When the snake maneuver is used to enter the head-on battle, the pilot rolls and then hovers horizontally with the pull rod. At this time, the flight control is working. At the same time, the fire control system can judge whether the aircraft is hovering left or right according to the program, so it can independently decide whether to open the left missile cabin or right missile cabin, and cool the air-to-air missile guide head in advance, which is the same as before Wait, these are all manually controlled by the pilot. Now they can be directly handled. The pilot's operation will be easier. After all, the computer will not make mistakes, and each step is quite accurate.

As for the combination with the engine, it is more advantageous. When you climb, you will automatically fill the engine fuel valve, or even operate the vectoring nozzle to turn accordingly.

When attacking the ground, simply set the route, and the aircraft can fly over automatically. The radar in front scans the ground with the synthetic aperture function. It can pull up or dive at any time according to the situation of the ground. The engine can increase or decrease thrust automatically. This is like the development of constant speed cruise to ACC adaptive cruise.

With these simple examples, we can know that after doing so, the combat effectiveness of fighter aircraft will be greatly improved. However, for aircraft designers, there are great risks.

At the beginning, teletype control and 1553B Data bus were equivalent to gathering the electronic equipment of the whole machine, but it was far from enough for the integration of flying fire and pushing.

It must adopt integrated avionics system and use a large number of distributed processors to process flight control, fire control, power and other data. It must have a large number of sensors and high-speed data transmission rate. Theoretically, using optical fiber transmission is the future high-speed and high-capacity channel, and can also avoid the problem of electromagnetic interference.

Another important problem is that the engine should be matched. The engine of the third generation is mechanically controlled, and the engine of the fourth generation should be transformed into digital control, so that it can be matched together.

"Does its engine match?" Qin Guan asked.

If the electronic system is your greatest strength, the engine is your biggest weakness.

Of course, with the success of the self-made turbofan-10, that is, the mapping imitation F110 engine, the third generation machine does not have to worry about the power problem, which is much easier to use than the previous Spey. However, in the era of the fourth generation machine, it will not be enough.

The fourth generation aircraft needs an engine with a thrust to weight ratio of 10. We can't do it. Moreover, the fourth generation aircraft still needs a vectoring nozzle.

"In terms of engine, we are now using an improved version of turbofan-10 engine. This version of engine adopts digital control system and adds vectoring nozzle behind it."

While talking, he took the people to the back of the plane. From here, you can see two chrysanthemums at the tail of the plane, one upward and the other downward!

In those years, after the j-20's first flight, there were endless arguments about the integration of flight, fire and propulsion, because the engines imported from Xiong country had no digital control, that is, ordinary analog control. At the same time, even if it was digital control, it was impossible to get the source code, which showed that the engines could not be integrated into the system.

However, the j-20 demonstrated the certainty of this system with its own flight performance, because it does not use imported engines at all. It is self-developed and can be changed as much as it wants.
