In the ordinary engine, the direction of the jet is fixed, that is, at the rear of the engine, the principle of recoil is used to push the aircraft forward, and the control of the aircraft is completed by various rudder surfaces.

Thrust vectoring technology, on the other hand, controls the direction of the jet airflow and directly provides additional torque, which will give the aircraft more agile maneuverability, but it will greatly increase the difficulty of the technology.

In the initial research, thrust vectoring is to put a baffle inside the tail nozzle, called a baffle, and change the direction of the jet by rotating the baffle to achieve thrust vectoring. This method has a simple structure and low cost, but it is heavy and very inefficient when thrust vectoring works.

Therefore, after that, the engineer began to make a fuss about the tail nozzle, directly so that the tail nozzle can move, which gave birth to the binary vector nozzle device, which can make the tail nozzle of the aircraft deflect in the pitch and yaw directions, so that the aircraft can produce additional moments perpendicular to the axis of the aircraft in the pitch and yaw directions, and has the ability to control thrust vectors. This binary vector nozzle is usually rectangular, and the American F-22 uses this vector nozzle.

However, the binary vector nozzle was not very efficient, and the technicians began to improve it again, becoming an axisymmetric thrust vector nozzle. The appearance of this nozzle is round, and it is composed of a steering adjustment actuator, a throat area adjustment actuator, an adjusting ring support mechanism, a nozzle control valve, and a heat-resistant seal. The Soviet Union's nozzle is digitally controlled, and the direct drive force is still hydraulic.

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

This system is far more complex than the binary nozzle, and even the Americans did not use it after comparison. In later Russia, it was sold everywhere, and in the end only Ah San, who liked tall equipment, was introduced, although the Russians vowed that the life of this nozzle was 250 hours, and it would eventually be extended to 500 hours. However, when Ah San is in use. It was found that it had to be replaced after more than 20 hours of use, otherwise various failures would occur.

And the treatment plan given by Russia is actually to ask Asan to provide more funds for the improvement of the vector nozzle.

Even the vector nozzle developed in later generations is at this level, not to mention now, in order to sell the Su-27, the Soviets installed this nozzle to show its mobility, but the reliability of this nozzle is so low that it almost has to be replaced after ten flight hours. Even though I have replaced it with a new one when I arrived, it still fails!

The Soviets did not say that they would protect their planes, especially the current test pilots, who were piled up with gold, and they would never put themselves in danger.

When it was discovered that the tail was on fire, Ishakov had no intention of controlling the plane at all.

Because, with constant maneuvering, his ground clearance has become lower and lower. Now, it's barely 80 meters above the ground! And. The attitude of the plane was tilted, at least thirty degrees on its side!

Catapult, catapult! Ishakov brought his legs together and pulled the red handle between his legs.

"Bang, with a crisp thud, the cap-breaking gun passed through the canopy. The canopy on top was pierced through four holes, and with it, the rocket below began to ignite, and the seat fixing system automatically activated, fastening Ishakov to the seat. At the same time, Ishakov felt his shoulders, waist and legs strained.

Immediately afterward, overhead, the ejection seat had shattered the cockpit canopy, and in the flying glass, Ishakov, who was tightly fixed to the seat, had already flown out of the cockpit.

At this time, the attitude of the plane is changing rapidly, and it has become inverted!

It's over, this Soviet guy is definitely dead! In this case, even if it is ejected, it will be rushed down by the head, and it will hit the ground before it has time to open the umbrella!

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 with the flame came out of the cockpit, and at this time, the head suddenly burst into flames, and the entire ejection seat quickly completed a flip in the air.

This ejection seat also has two attitude adjustment rockets in the headrest area, and the nozzles point to the sides; When the fighter is in the state of rollover ejection, the downward attitude rocket will be activated, helping the ejection seat to change direction and fly high to obtain a greater parachute opening height. Thanks to the optimization of the parachute opening program and the ability to actively control the attitude, the low-altitude inverted ejection of this seat reaches a staggering height of 50 meters!

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

In this way, in the eyes of everyone, the ejection seat completed a chic turn, when the attitude was adjusted, the two stabilizing umbrellas in the two casing connecting rods on the back of the seat were immediately opened to ensure the stability of the seat, and at the same time, the attitude was also adjusted to the vertical direction, under the action of the rocket thrust, continue to fly upward.

The K-36 seat has excellent attitude stability thanks to the two stabilizer bars behind it that extend up to 1.8 meters and the rotatable parachute system. The two stabilizer bars are abducted 15 degrees from the heading base, so that the stabilizer parachute is outside the turbulent zone behind the chair; No matter how the posture changes, there is always a stable function in a strong and effective state, which can quickly pull the seat back to its normal position. In this way, the ejection seat can always remain in a "standing" position.

After the rocket engine at the bottom is turned off, it is already high enough in the air, and then, the seat is separated from the person, and the main parachute is opened!

The orange and white umbrella flowers appeared in the air, and everyone's eyes widened again, obediently, this umbrella was not sewn tightly!

The parachute of the K-36 ejection seat adopts a slit structure, which is composed of 8 symmetrical slits to achieve high and low speed dual-mode work: the slit is very small at low speed, and the characteristics of the rescue parachute are close to those of the unslit and unclosed parachute, so that the parachute has high resistance, decelerates quickly, and can be safely rescued at a very low altitude. At high speed, the slit will be forced to open under the air pressure generated at high speed, and a part of the air flow will be directly discharged to reduce the load of the parachute and avoid damage.

This advanced parachute has a maximum opening height of 6,000 meters and a maximum opening speed of 650 km/h. At the same time, the HTY-5 used by the J-10 has a maximum parachute opening altitude of 4,000 meters and a maximum parachute opening speed of 600 km/h. As for the HTY-6 seat used in second-generation aircraft such as the Flying Leopard and J-8, the maximum parachute height and speed are only 3,000 meters and 520 km/h.

All eyes were on the parachute, not paying attention to the fighter that had fallen to the ground, the only Su-35 fighter with a thrust vector in the USSR, which was almost given the number Su-37 inside, and crashed like this.

The fire engine drove quickly past, and the crash site was not far from the airport.

The rescue vehicle also drove in the direction of the falling umbrella flowers, and the siren kept sounding, and the people at the scene were stunned and shocked.

Every performance of the Soviets gave a great shock to the people present, but those dazzling performances could not bring them a greater shock than the current ejection escape!

Although China's economy is still very weak, and the country's financial resources are limited, it must not be stingy in some aspects! If such a dangerous situation occurs in a domestic fighter, it will definitely be a plane crash and a death! And the ejection seat of the Soviets was able to allow the pilot to escape in such a situation! This ejection seat technology must be introduced! It's best to get a few ejection seats and hand them over to domestic manufacturers to imitate!

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

Mhammad is also an eye-opener today, and Mhammad, who came from later generations, naturally knows that the performance of this ejection seat of the Soviets is simply too good, so good that the Americans have imported some of it. In previous air shows, this ejection seat can also be regarded as a star. Far from it, in the most recent 89 Paris Air Show, a Soviet MiG-29 fighter plane crashed because it hit a bird, and the pilot was successfully ejected and rescued when the plane was 90 meters above the ground and almost vertical, showing his face in front of the entire West.

In later generations, in 93, two MiG-29s collided and crashed during an air show at the Paris Air Show. The Su-99МК was ejected at almost zero altitude at the Paris Air Show, and in July 02, the Su-27 of the Ukrainian Air Force had an accident at an air show in Lviv, and the pilots were safely escaped in extremely dangerous situations. Especially in the accident in 02, the Su-27 touched the ground and exploded, the fireball rolled and rushed into the crowd, and in the pilot's dashing ejection, 83 people were killed and more than 100 were injured in the ground audience.

The K-36 ejection seat almost never went wrong, and it was the best guarantee for the crazy Ivan, while in comparison, the Americans were much worse, in history, in the 91 Gulf War, 4 of the 16 U.S. pilots who ejected and escaped had spinal fractures, and only 7 of them were completely uninjured after jumping to the ground.

And now, Ishakov, the Soviet pilot who had escaped safely with this upside down, returned to the venue in a jeep that had gone to meet him, with a somewhat depressed face.

"Ishakov, it was your mistake that caused this accident!" Seeing Ishakov, who was unscathed, Goryshin immediately said, and at the same time glanced at Ishakov.

You can't admit that it's a defect in the aircraft, right? It's either a defect in the aircraft, or a problem with the operation of personnel! Therefore, Golishin immediately made up his mind, and at the same time hoped that Ishakov would admit it.

Who knows, Ishakov immediately shook his head: "No, it's a problem with the vector nozzle." ”

Ishakov is a meritorious test pilot of Sukhoi, so he will not urinate Gorishin, technical problems, even Simonov is not afraid of him, it is obviously a vector nozzle failure! (To be continued......)
