Chapter 696 Integrated Avionics System

"Compared with passive phased array radar, the advantage of active phased array radar is that each basic component can both transmit and receive. Therefore, when some components are damaged, the remaining components can still function, which increases the operating time of the airborne radar." Kanchelskiy said: "At the same time, by controlling the segmented radar beam, we can allow the radar to lock onto a target while also separating part of the beam to scan other airspace."

Why develop active phased array radar? Because of its advanced performance! The necessary standard configuration of the new generation of fighter jets is active phased array radar!

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

"For what?" asked Kanchelskis.

"It can detect stealth aircraft!" Andre said, "Active phased array radar can focus the beam to one direction to the maximum extent. In this way, it can detect stealth aircraft at a farther distance than ordinary radar."

Stealth aircraft found! Now, Andre has taken the threat of stealth aircraft to a new level! Everything is based on defeating stealth aircraft as the top priority.

Although there is not much breakthrough in the basic principles of radar, phased array radar can concentrate the beam and energy to the maximum extent, and theoretically has the ability to detect stealth aircraft from a longer distance.

"The shape of this radar antenna should be able to be combined in any way, right?" Andre continued, "Our radar antenna is not only circular, but also has a diamond-shaped structure."

The active phased array radar antenna does not need to move, and it radiates electromagnetic waves by changing the phase. Therefore, the shape of the antenna can be arbitrarily formed. The diamond-shaped structure that Andre mentioned naturally has a purpose.

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

"Yes, the antenna shapes can be combined arbitrarily, and the antenna size can also be changed. It can not only be stuffed into the nose of our new generation of fighter jets, but also various aircraft. If the cost is not considered, a small radar can also be stuffed into the air intake cone of the MiG-21." Kanchelskiy said.

"It seems that our airborne radar development progress is good." Andre said.

In the development of Soviet fighters, the airborne electronic system was often a lag. Now, with the help of the electronic technology of the island countries, we have 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 are technology obtained from the island countries!

"Yes, our main task now is to write the corresponding program." Kanchelskiy said: "Although we have developed a new airborne computer with greatly improved performance, the computing power is still insufficient to process the data of the active phased array radar. We can only optimize the program on the one hand and develop an airborne computer with higher computing power on the other hand."

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

Integrated avionics system! Currently, the Soviet Su-27 and MiG-29 are still distributed avionics, each system is responsible for its own system, such as radar and optoelectronic probe, each responsible for its own aspects. The new generation of fighters need to integrate all these external sensors to achieve a higher level of performance. At the same time, the integration of flight, fire and propulsion is also a necessary choice.

This requires extremely powerful computer performance, which is beyond the reach of current electronic technology.

However, it doesn't matter if it can't be achieved for the time being, because according to Moore's Law, the update speed of electronic systems is quite fast! And now, the development progress of our airborne electronic systems is ahead of the times. After all, the development of fighter jets has just begun, and there are still five or six years! During this period of time, it is enough for electronic equipment to be upgraded!

In this case, we should first use commercial computer systems as substitutes. Commercial computers do not need to consider protection against electromagnetic interference, electromagnetic pulses, etc., and their computing speeds far exceed those of airborne computers. By the final stage of fighter flight testing, new airborne computers with higher computing power will have achieved breakthroughs.

Hearing Andre's words, Kanchelskis opened his mouth. Is this really possible? If he follows Andre's advice, the problems he faces will be solved. However, if the new onboard computer chip fails to meet the requirements in the future, it will slow down the progress.

"I believe that the performance of our Soviet electronic technology, even our military computer systems, will double every 18 months," Andrei said. "When our new fighter jets enter the final assembly and flight test stage, our airborne electronic equipment will definitely be able to meet the needs."

Andrei's inspection of the Tikhmilov Instrument Manufacturing Institute was very fruitful. According to Andrei's proposal, the Tikhmilov Instrument Manufacturing Institute adjusted its progress and solved the difficulties in the research and development process. In terms of active phased array radar, it has become a world leader!

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

Active phased array radar is the trend of the future!

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

In the field of aerospace, the Lyulka-Saturn Design Bureau is a huge giant. This design bureau was established in March 1946, and the first chief designer was A.M. Lyulka. Since its inception, this design bureau has been producing a large number of engines for the aviation and aerospace fields of the Soviet Union!

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

The Soviet Union's next-generation fighter jet has chosen the AL-41 engine designed by the Lyulka Design Bureau, which has a thrust of up to 20 tons and a thrust vectoring function. Its indicators in all aspects exceed those of the current Al-31 engine. The development progress of this engine will also determine whether the next-generation fighter jet can be successfully finalized.

However, since the Lyulka Design Bureau was far away in Leningrad, Andrei first came to the Salute Engine Factory before visiting the Lyulka Design Bureau.

In later generations, these two aviation companies are both well-known, and many people are confused about their relationship. In terms of time, the Salute Factory is older, dating back to 1912. Now, the Lyulka Design Bureau is mainly responsible for design, while the Salute Factory is mainly responsible for production. This is the relationship.
