"Compared with 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 play a role, improving the operation time of the airborne radar. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 "At the same time, by controlling the radar beam in sections, we can allow the radar to lock on to one target and at the same time split a portion of the beam to scan other airspace," Kanchelsky said. ”

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

Andrei nodded: "Yes, at the same time, there is an updated use for this radar. ”

"What is it for?" Kanchelsky asked.

"It's the discovery of stealth planes!" "Active phased array radar, which maximizes the concentration of the beam in one direction, allows stealth aircraft to be detected at a greater distance than ordinary radars," Andrei said. ”

Discover stealth aircraft! Now Andrey has taken the threat of stealth aircraft to a new level! Everything is done with the victory over 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 maximum, and theoretically has a longer detection capability for stealth aircraft.

"The shape of this radar antenna should be able to be combined in any way, right?" Andrei continued: "Our radar antennas are not only round, but also have a diamond-shaped structure. ”

The active phased array radar antenna does not need to move, but radiates electromagnetic waves by changing the phase, so the shape of the antenna can be arbitrarily composed, and the diamond-shaped structure that Andrei said naturally has a purpose.

Ustinov next to him understood what Andrei meant, and it seems that in Andrei's heart, the project of the new fighter of the Sukhoi Design Bureau is the most suitable choice for him.

"Yes, the antenna shape can be combined at will, and the antenna size can also be changed, not only into the nose of our new generation fighters, but also in all kinds of aircraft, and if you don't consider the cost, you can also cram a small radar into the air intake cone of the MiG-21." Kanchelsky said.

"It seems that our airborne radar development is progressing well." Andrei said.

The development of Soviet fighters, the on-board electronic system is often delayed, and now, with the help of the electronic technology of the island country, their own side is not only catching up with the Western world, but also making a breakthrough, at this time, I am afraid that the Americans have not mastered the active phased array radar! Historically, their T/R components have been technology obtained from island nations!

"Yes, our main task now is to write the corresponding program." "Although we have developed a new on-board computer with a significant increase in performance, the computing power to process data from the active phased array radar is still insufficient," Kanchelsky said. We can only optimize the program on the one hand, and develop an on-board computer with higher computing power on the other. ”

"Our airborne avionics system should be an integrated avionics system, right?" Andre said: "Such a system should require a more powerful computer, if our current on-board computer performance is insufficient, we can first try to integrate the system on a commercial computer system." ”

Integrated avionics system! At present, 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 responsible for their own aspects. The new generation of fighters needs to integrate these external sensors to achieve a higher level of performance, and at the same time, the integration of Flying Fire is also a necessary choice.

In this way, the computer needs to be extremely powerful, which is not yet available with electronic technology at this time.

However, it doesn't matter if you can't reach it for the time being, because according to Moore's Law, electronic systems are updated quite quickly! And now, the development progress of our own airborne electronic system is ahead of time, after all, the development of fighter aircraft has just begun, and there are still five or six years to go! And in that time, that's enough for an upgrade of electronic equipment!

In this case, the commercial computer system is used to replace it, and the commercial one does not need to consider the anti-electromagnetic interference, electromagnetic pulse, etc., and the computing speed is far more than the on-board computer, and when the final fighter is tested and flown stage, the new airborne computer with higher computing power will also make a breakthrough.

Hearing Andrei's words, Kanchelsky opened his mouth, in this way, is it really possible? If you follow Andrey's opinion, then the problem you are facing will be solved, but if the new onboard computer chip cannot meet the requirements in the future, it will slow down the progress.

"I believe that our Soviet electronics, even our military computer systems, will double in performance every 18 months." Andrei said: "When our new fighter enters the final assembly test flight stage, our on-board electronic equipment will definitely be able to meet the needs." ”

Andrey's inspection of the Tikhmilov Instrument Building Research Institute was very fruitful, and according to Andrei's proposal, the Tikhmilov Instrument Manufacturing Research Institute adjusted its own progress, solved the problems on the road of development, and came to the forefront of the world in terms of active phased array radar!

At the same time, in the end, Andrei also encouraged these scientific researchers that airborne radar is only one of them, and the development of a new active phased array radar for warships to replace the sky sentry system will also be a task in the future.

Active phased array radar is the trend of the future!

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

In astronautics, the Rurika-Saturn Design Bureau was a huge giant, this design bureau was founded in March 46, and the first general designer was A.m. Rurika. Since its birth, this design bureau has been producing a large number of engines for aviation, astronautics in the USSR!

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, and the Al-31 engine on the current Su-27 fighter is a masterpiece.

And the power of the next generation of Soviet fighters has been chosen for the Al-41 engine designed by the Rurika Design Bureau, with a thrust of up to 20 tons, with a thrust vectoring function, and in all aspects of the indicators surpasses the current Al-31 engine. The development progress of this engine will also determine whether the next generation of fighters can be successfully finalized.

However, since the Rurika Design Bureau was far away in Leningrad. So, before going to visit the Rurika Design Bureau, Andrei first came to the Salyut engine plant.

In later generations, these two aviation companies are famous, many people do not understand their relationship, in terms of time, the Salyut factory is much older, the earliest can be traced back to 1912, and now, the Rurica Design Bureau is mainly responsible for design, and the Salyut factory is mainly responsible for production, such a relationship.
