Chapter 990： Still want to have fun?

At this time, the ace test pilot of Sukhoi in the sky, Viktor Pugachev, was flying in the sky. He disconnected the telex system and used manual operation. Only in this way can the aircraft enter the spiral. state, otherwise, the fly-by-wire system will prevent the aircraft from entering this state!

At an altitude of 10,000, Pugachev calmly shouted in the radio: "Test machine No. 03, please enter the spin state."

"You can enter."

Following the order, Pugachev began a series of preparations, first locking the accelerator, and fixing the accelerator at the idle state. The engine of this interceptor is not easy to serve, and it is easy to cause the engine to stop.

As the throttle entered idle, the plane began to slow down, and finally, the plane swayed side to side like a drunk.

"123 Come on!". Pugachev shouted, and then vigorously pushed the left rudder lever and then pressed the lever to the right to the end. The huge fighter swayed and swayed a few times and quickly deflected to the left. The Su-37's tail spin came fast and violent.

The clouds were spinning rapidly, and the plane dropped sharply as it rotated. Pugachev kept counting, watching the spin times and laps.

Soon, it's time to change it! Pugachev kept his eyes on the dashboard and memorized all the data in the spin.

Any pilot needs to learn how to get out of the spin, but they just follow the flight manual, and the test pilot needs to find out how to get out of the spin! Any pilot is afraid of spins. If they do not have a good psychological quality, it is difficult to bear the huge psychological pressure of spins.

And Pugachev, who has flown the Su-27's tail spin many times, is the Su-27's tail spin that he first changed. The tail spin characteristics of the third-generation aircraft and the method of changing the tail spin are similar to those of the second-generation fighter. There is a big difference from the ordinary second-generation machine. As long as the brain is not dizzy, push the stick in the opposite direction to the end, and the tail spin can be recovered. However, the new winglet-loaded, highly maneuverable aerodynamic layout is very difficult.

In the initial spin test flight of the MiG-23, many test pilots paid the price of blood, and finally changed it! This is a new way, including anti-rudder, holding the pole, and pressing the stick.

At this time, the height is five thousand! Pugachev quickly followed the predetermined action to change the spin. However, under the strong impact of the airflow, the aircraft showed no sign of slowing down the rotation speed.

From the outside, the Su-37 seems to be intoxicated by the graceful arc of the tail spin and is unwilling to come out!

"Disconnect the differential horizontal tail limiter!" shouted the test flight commander.

This is the last resort! Help recover from spin with a differential stern! Pugachev skillfully flipped the switch to disconnect the limit of the flat tail. The flat tail was deflected almost at a 90-degree angle, and the control was the most powerful!

The plane finally reacted, and the rotation speed of the plane slowed down rapidly to turn to the tenth lap and finally stopped spinning. Su-37 held a high attitude and flew again!

"The spin test was a success," Simonov said. "It was as we imagined."

Just as imagined! Because the body of the Su-37 and the entire aerodynamic layout are completely similar to the Su-27, the flight control rate of the aircraft is very similar, which greatly reduces the difficulty of aircraft design! It can even be said that the current Su-37 is not a new aircraft in the full sense, it can be said to be a stealth modification of the Su-27.

The slow progress of the Mikoyan Design Bureau is because the MiG 1.44 is a brand new aircraft. The control of the canard layout is non-linear, and the programming of the telex system alone takes a lot of time and energy!

The current spin test recovery is very similar to that of the Su-27. In the process of test flight, a lot of experience can be used for reference, and the speed is even faster.

The plane landed on the runway again, and when he came out of the cockpit, Pugachev saw Andrei at the front of the crowd that greeted him outside, and his face was immediately excited.

"Marshal Andrei, do you want to fly a circle?" Pugachev took off his helmet and said to Andrei.

This is an approachable general, and, the general is also a great pilot! Pugachev still remembers that when he was flying the Su-27, Andrei once asked to fly a lap instead of him. At that time, General Andrei only flew on the simulator, and as a result, it flew quite wonderfully!

Now that General Andrei is coming to the test flight base, do you still want to have fun?

However, before Andrei could speak, Pugachev, who was beside him, spoke up: "Our plane has only been fueled for one sortie, and now, we have to interpret the data of this test flight, so, Please be patient with Marshal Andrei, and then fly when there is a chance in the future."

What a joke! Last time Andre got on the Su-27, they all sweated a lot. This time, Andre can't let Andre get on the plane directly!

Fortunately, Andre didn't plan to get on the plane directly. He was able to fly the Su-27 at the beginning because it was his old job and the most familiar model. Now, although this plane has been improved, its aerodynamic characteristics are definitely There has been a change. If there is a two-seater model, you can go up and slip around, and now this single-seater model is better.

"Interpretation of the data." It seems that they were afraid that Andrei would get on the plane. Under Pugachev's order, many technicians gathered around, opened the hole in the outer skin of the plane, and inserted the equipment.

Andrei smiled and didn't say anything about the hands and feet of these people. They were also kind.

A technician even opened the radome in front. Andre looked at the exposed antenna shape and became excited. Behind the antenna, the hydraulic motor and gimbal are no longer needed. They are completely fixed because, Radar beams fly out by changing the phase!

However, compared with later generations, each of these t/r components seems to be larger.

"This is our advanced radar." Seeing Andrei's interest, Simonov said: "This radar, with 800 transmitter-receiver units, can converge all beams and sweep to 200 kilometers away, or Spread the beam, track ten targets at the same time, and attack two of them."

Eight hundred launch units! After all, the era has only advanced to the beginning of 1984! In later generations, this radar matured almost in the 21st century. At that time, the apg77 radar in the United States had 2,200 transmitting units and had powerful performance. And now, because the volume is still too large, it only accommodates 800 units!

Although there are only 800 of them, the performance is already quite powerful, similar to the passive phased array radar of MiG 31, but the power consumption is greatly reduced, and the volume and weight are reduced. This is already a mature product!

After reading the radar, Andre went up the gangway again and looked at the cockpit. Sure enough, most of the instruments in the cockpit are still mechanical. The glass cockpit of later generations has not yet been realized. , However, although there is no one level three, but the most conspicuous position of the cockpit, there are still two LCD screens on the left and right, and the screen size far exceeds the radar screen of the cathode ray tube.

"In the cockpit, the second-generation liquid crystal display jointly developed by us and the island countries is applied. The radar on the right and the integrated display on the left can display various flight data, receive positioning signals, display digital maps, etc. ." Simonov introduced to Andrei.

He is quite satisfied with this cockpit. Due to the advancement of his own electronic technology, he can install a large screen on the fighter! The displayed data far exceeds that of the instrument. Moreover, it can make the pilot more concentrated, especially to facilitate the reading after the event. All these data can be stored.

Andre nodded: "Yes, we are making rapid progress in the electronic system, but this is not enough. In the future, our fighter jets should be able to achieve a large screen, so the mechanical instruments are cancelled."

That is the cockpit of the future f35, it is very sci-fi, but it can definitely be realized!

Suddenly, Simonov was stunned, Marshal Andrei, are you so confident? A mechanical instrument is not needed, what if these electronic instruments fail?

Looking at Simonov's expression, Andrei knew that people didn't believe it, and he didn't blame him. After all, the electronic technology of this era is not enough! Many technologies of later generations, in the present, are already sci-fi.

After staying in the test flight institute for a long time, Andrei was about to return to the Ministry of Defense, and in the car, Putin, the bodyguard and driver who came to pick him up, said to him while driving: "Marshal Andrei, what you asked for The investigation, we already have the results."
