Compared to passive phased array radar, the advantage of active phased array radar is that each basic component can both transmit and receive, so when some of the components are damaged, the rest of the components can still be Play a role and improve the running time of the airborne radar. Kancherski said: At the same time, through the segmented control of the radar beam, we can let the radar lock on a target while also separating a part of the beam to scan other airspace.

Why develop active phased array radar? It is because of the advanced performance of this radar! The necessary standard equipment for the new generation of fighters is the active phased array radar!

Andre nodded: Yes, at the same time, this radar has a newer purpose.

For what? Kanchelski asked.

It is to discover stealth aircraft! Andre said: Active phased array radar can concentrate the beam in one direction to the maximum. In this way, the distance to detect stealth aircraft is farther than that of ordinary radar.

Spotted the stealth plane! Now, Andre has raised the threat of stealth aircraft to a new level! Everything is based on defeating stealth aircraft as the first priority.

Although there is not much breakthrough in the basic principle of radar, phased array radar can concentrate the beam and energy to the greatest extent, and theoretically has a farther detection ability for stealth aircraft.

The shape of this radar antenna should be able to be combined arbitrarily? Andre continued: Our radar antenna is not only circular, but also has a rhombus structure.

The active phased array radar antenna does not need to move, and radiates electromagnetic waves by changing the phase. Therefore, the shape of the antenna can be formed arbitrarily, and the rhombus structure mentioned by Andre is naturally purposeful.

Ustinov next to him understood what Andre meant. It seemed that in Andre's mind, the Sukhoi Design Bureau's new fighter project was the most suitable choice for him.

Yes, the shape of the antenna can be combined arbitrarily, and the size of the antenna can also be changed. Not only can it be stuffed into the nose of our new generation of fighters, but also all kinds of aircraft. If you don't consider the cost, give the MiG-21 A small radar can be crammed into the air intake cone of the aircraft, Kanchelski said.

It seems that the development of our airborne radar is progressing well. Andre said.

The development of Soviet fighter jets, the airborne electronic system often lagged behind, but now, with the help of the electronic technology of the island country, our own side not only caught up with the Western world, but also achieved a breakthrough. At this time, I am afraid that the Americans have not figured out the active phased array. radar! Historically, their T/R components were technology obtained from island countries!

Yes,

Our main task now is to write the corresponding program. Kanchelski said: Although we have developed a new airborne computer, the performance has been greatly improved, but the computing power is still not enough to process the data of the active phased array radar. We can only optimize the program on the one hand, and develop an onboard computer with higher computing power on the other hand.

Our airborne avionics system should be an integrated avionics system? Andre said: Such a system should require a computer with more powerful performance. If our current onboard computer is not capable enough, we can Try system integration on a commercial computer system first.

Integrated avionics system! Now, the Soviet Union's Su-27 and MiG-29 are still distributed avionics, and each system is responsible for each system, such as radar and photoelectric probes, which are each responsible for their own aspects. The new generation of fighters needs to integrate these external sensors to achieve a higher level of performance. At the same time, the integration of flying fire and pushing is also a necessary choice.

In this way, the computer performance is required to be extremely powerful, which cannot be achieved by electronic technology at this time.

However, it doesn't matter if you can't reach it temporarily, because according to Moore's Law, the update speed of electronic systems is quite fast! But now, the development progress of our own airborne electronic system is ahead of schedule. After all, the development of fighter jets has just begun, and there are still five or six years to go! And during this period of time, it is enough to upgrade the electronic equipment once!

That being the case, first replace it with a commercial computer system. The commercial computer system does not need to consider anti-electromagnetic interference, electromagnetic pulse, etc., and its computing speed far exceeds that of the on-board computer. When the final test flight stage of the fighter jet, the new computer with higher computing power The onboard computer also made a breakthrough.

Hearing Andrei's words, Kanchelski opened his mouth, so, is it really okay? If you follow Andre's opinion, then the problem you are facing will be solved, but if the new airborne computer chip fails to meet the requirements in the future, it will delay the progress.

I believe that our Soviet electronic technology, even our military computer system, will double in performance every 18 months. Andrei said: When our new fighter jet enters the final assembly test flight stage, our fighter jet will Electronic equipment must be able to meet the needs.

Andre's inspection of the Tikhmilov Instrument Manufacturing Research Institute was very effective. According to Andre's proposal, the Tikhmilov Instrument Manufacturing Research Institute adjusted its progress and solved the problems on the road to development. The problem, active phased array radar, has come to the forefront of the world!

At the same time, Andre finally encouraged these scientific researchers. Airborne radar is only one of them. Developing a new active phased array radar for warships to replace the sky sentinel system will also be a task in the future.

Active phased array radar is the future trend!

After leaving the Tikhmilov Institute of Instrument Manufacturing, Andrei's next stop was the Rurika-Saturn Design Bureau.

In terms of aerospace, the Rurika-Saturn Design Bureau is a huge giant. This design bureau was established in March 1946, and the first chief designer was А.М. Rurika. Since its birth, this design bureau has been producing a large number of engines for Soviet aviation and aerospace!

A large number of fighter engines in the Soviet Union start with AL, which is the abbreviation of Rurika, and the Rurika Design Bureau has been designing various jet engines since the end of World War II. The AL on the current Su-27 fighter The -31 engine is a masterpiece.

The power of the Soviet next-generation fighter has chosen the AL-41 engine designed by the Rurika Design Bureau, with a thrust of up to 20 tons and a thrust vectoring function. All indicators exceed the current Al-31 engine. The development progress of this engine will also determine whether the next-generation fighter can be successfully finalized.

However, since the Rurika Design Bureau is far away in Leningrad. So, before visiting the Rurika Design Bureau, Andrei first came to the Salyut Engine Factory.

In later generations, these two aviation companies are well-known, and many people do not understand their relationship. In terms of time, the Salyut Factory has a longer history, dating back to 1912 at the earliest. Now, the Rurika Design Bureau is mainly responsible for the design. The Salute Gun Factory is mainly responsible for production, which is such a relationship.
