For ordinary engines, the direction of the airflow ejected is fixed, which means that the recoil principle is used to push the aircraft forward, and the control of the aircraft is accomplished by various rudder surfaces.

Thrust vector technology controls the direction of the ejected airflow and directly provides additional torque, which will give the aircraft more agile maneuverability, but will greatly increase the difficulty of the technology.

In the early research, the thrust vector is to place a baffle inside the tail nozzle, called a baffle plate, which changes the direction of the jet by rotating the baffle to achieve the thrust vector. This method is simple in structure, low in cost, but heavy in weight, and the thrust vector is very efficient when working.

So, the engineer then started to make the tail nozzle and directly make the tail nozzle move. This gave birth to the binary vector nozzle device, which allowed the aircraft's tail nozzle to deflect in the pitch and yaw directions, so that the aircraft can generate additional torque perpendicular to the aircraft axis in the pitch and yaw directions, and has the ability to control the thrust vector. This binary vector nozzle is usually rectangular, and the American F-22 uses this vector nozzle.

However, the efficiency of the binary vector nozzle is not high, and technicians have begun to continue to improve and become an axisymmetric thrust vector nozzle. The appearance of this nozzle is circular, consisting of a steering adjustment actuator, a throat area adjustment actuator, an adjustment ring support mechanism, a nozzle control valve and a heat-resistant sealing plate. This set of nozzles in the Soviet Union uses digital wire-speed control, and the direct driving force is still hydraulic.

Relying on this vector nozzle, the Su-35 fighter has become a super-maneuverable aircraft, but its shortcomings are also obvious, and its biggest disadvantage is reliability!

This system is much more complicated than binary nozzles, and it was not even used after comparison by Americans. Later Russia promoted it everywhere, but in the end, only A San, who likes high-end equipment, was introduced. Although the Russians boasted that the life of this nozzle is 250 hours and will eventually be extended to 500 hours. However, when A San was in use, he found that it had to be replaced after more than 20 hours of use, otherwise various faults would occur.

The solution given by Russia actually requires A San to provide more funds for the improvement of vector nozzles.?

Even the vector nozzles developed in later generations were at this level, not to mention now, in order to promote Su-27, the Soviets installed this nozzle to show their maneuverability. However, the reliability of this nozzle is too low, and it has to be replaced in almost ten flight hours. Now, although the new one has been replaced by when we came, it still has a malfunction!

The Soviets had no idea of ​​protecting planes, especially the current test pilots, who were piled up with gold, and they would never put themselves in danger.

When I found the tail fire, Ishkov had no intention of controlling the plane.

Because, with the continuous maneuvering, his height from the ground has become lower and lower. Now, it is almost less than eighty meters above the ground! Moreover, the plane's posture is inclined, at least thirty degrees!

Eject, eject! Ishkov put his legs together and pulled the red handle between his legs.

"Bang, with a crisp sound, the breach gun passed through the canopy cover, piercing the top of the canopy cover into four holes, and then the rocket below began to ignite, and the seat fixing system automatically started, tightening Ishkov to the seat. At the same time, Ishkov felt his shoulders, waist and legs tightened.

Immediately afterwards, the ejection seat had been shattered on the canopy cover. In the flying glass, Ishkov, who was tightly fixed to the seat, flew out of the cockpit.

At this time, the plane's posture is changing rapidly and has become reversed!

After that, this Soviet man must be dead! In this case, even if he ejected, his head would rush down. He would not have time to open the umbrella and would hit the ground!

Most of the people present were from the Air Force and knew the danger of ejection, and in this case, there was absolutely no possibility of survival!

The ejection seat dragging the flames came out of the cockpit. At this moment, a fire suddenly appeared on the head, and the entire ejection seat quickly completed a flip in the air.

This ejection seat also has two posture adjustment rockets in the head-rest position, and the nozzle points to both sides; when the fighter is in a rollover ejection state, the downward attitude rocket will start, helping the ejection seat change direction and fly to a higher level, and obtain a larger parachute opening height. Relying on the parachute opening procedure optimization and attitude active control ability, the low-altitude reverse ejection height of this seat reaches an astonishing 50 meters!

It can be said that the ejection seat at this time is like a miniature aircraft!

In this way, under everyone's gaze, the ejection seat completed a chic steering. When the posture was adjusted, the two stable umbrellas in the two casing connecting rods on the back of the seat were immediately opened to ensure the stability of the seat. At the same time, the posture was also adjusted to a vertical direction, and continued to fly upwards under the influence of the rocket thrust.

The posture stability of this k-36 seat is very good, which is the role of the two stabilizing rods that extend up to 1.8 meters behind it, as well as the rotatable stabilizing umbrella system. These two stabilizing rods are outstretched by 15 degrees based on the heading, so that the stabilizing umbrella is outside the turbulent zone behind the chair; no matter how the posture changes, there is always a stabilizing function in a strong and effective state, which can quickly pull the seat back into a normal position. In this way, this ejection seat can always maintain a "standing position".

After the rocket engine at the bottom was turned off, it was already in the air high enough. Then, the seats separated from the people and left the main umbrella!

The orange and white umbrella flowers appeared in the air, and everyone opened their eyes again. Be good, the umbrella was not sewn tightly!

The parachute of the k-36 ejection seat adopts a slit structure, and achieves high and low-speed dual-mode operation by 8 symmetrical slits: the slit is very small at low speed, and the characteristics of the life-saving parachute are close to that of the unslit and unsatisfied parachutes. Such parachutes have a large resistance, fast deceleration, and a very low altitude can be used to safely save lives. At high speed, the slit will be forced to open under the air pressure generated by the high speed, directly discharged part of the airflow to reduce the load on the parachute and avoid damage.

The maximum parachute opening height of this advanced parachute reaches 6,000 meters and the maximum parachute opening speed reaches 650 kilometers per hour. At the same time, the maximum parachute opening height of the J-10 is 4,000 meters and the maximum parachute opening speed is 600 kilometers per hour. As for Fei Leopard, the maximum parachute opening height and speed of the Hty-6 seats used by the J-8 second-generation aircraft is only 3,000 meters and 520 kilometers per hour.

Everyone's eyes were on the parachute, not paying attention to the fighter that had fallen to the ground, the only Su-35 fighter in the Soviet Union, almost all of which were given the Su-37 number inside, crashed like this.

The fire truck quickly drove over, and the crash site was not far from the airport.

The rescue vehicle also moved towards the direction of the umbrella flower falling. The sirens kept ringing, and the people at the scene were stunned and shocked.

Every performance by the Soviets shocked the people present, but those dazzling performances were not as shocked as the current catapult escape!

Although China's economy is still very weak and the country can provide limited financial resources, it must not be stingy in some aspects! If domestic fighter jets encounter such danger, the plane will definitely be destroyed and killed! The Soviet ejection seats can allow pilots to escape under such circumstances! The technology of this ejection seat must be introduced! It is best to get a few ejection seats and leave them to domestic manufacturers for imitation!

Air Force Commander Wang Hai made up his mind almost instantly.

Mhamad was also an eye-opener today. Mhamad from later generations naturally knew that the performance of the Soviets' ejection seats was so excellent, so excellent that Americans imported some. At previous air shows, this ejection seat was also a star. Not to mention it, recently, at the Paris Air Show in 1989, a Soviet MiG-29 fighter crashed due to a bird crash. The pilot successfully ejected and rescued when the plane was 90 meters above the ground and was almost vertical, showing his face in front of the entire Western side.

In later generations, in 1993, two MiG-29s collided and crashed during a flight show at the Paris Air Show. At the Paris Air Show in 1999, the Su-30mk double-ejected at almost zero altitude. In July 2002, the Ukrainian Air Force Su-27 was in Lviv's flight show accident. The pilots all escaped safely under extreme danger. Especially in the accident in 2002, the Su-27 hit the ground and exploded, and the fireball rolled into the crowd. When the pilot's casual ejection was shot, 83 people died and more than 100 people were injured.

The k-36 ejection seat has almost never made any mistakes, and is the best guarantee for the crazy Ivan. In comparison, Americans are much worse. Historically, in the 16 American pilots who escaped from the 16 ejection escaped, four of them had spinal fractures. After jumping to the ground, only 7 people were not injured in their bodies at all.

Now, the Soviet pilot Ishkov, who had escaped safely, returned to the venue in a jeep that had been to greet him, with a little frustrated face.

"Ishkov, it was your wrong operation that led to this accident!" Seeing Ishkov who was unscathed, Gorishin immediately said, and at the same time winked at Ishkov.

It is impossible to admit that it is an aircraft defect, right? It is not an aircraft defect, it is a problem of personnel operation! Therefore, Gorishen immediately made a conclusion and hoped that Ishakov could admit it.

Unexpectedly, Ishakov immediately shook his head: "No, it's a problem with vector nozzles."
Chapter completed!
