For ordinary engines, the direction of the airflow ejected is fixed, that is, at the rear of the engine, 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 jetted airflow and directly provides additional torque. This will give the aircraft more agile maneuverability, but it will greatly increase the technical difficulty.

In the initial research, thrust vectoring was achieved by placing a baffle, called a baffle, inside the tail nozzle, and rotating the baffle to change the direction of the jet to achieve thrust vectoring. This method has a simple structure and low cost, but it is heavy and the efficiency of thrust vector operation is very low.

Therefore, engineers then began to work on the tail nozzle, directly allowing the tail nozzle to move. This gave birth to the binary vector nozzle device, which can deflect the aircraft's tail nozzle in the pitch and yaw directions. The aircraft can generate additional moments perpendicular to the aircraft axis in the pitch and yaw directions, and has thrust vector control capabilities. This kind of binary vector nozzle is usually rectangular, and the American F-22 uses this kind of vector nozzle.

However, the efficiency of the binary vector nozzle was not high, so technicians continued to improve it and became an axisymmetric thrust vector nozzle. This nozzle is circular in appearance and consists of a steering adjustment actuator, a throat area adjustment actuator, an adjustment ring support mechanism, a nozzle control valve, and a heat-resistant sealing sheet. The Soviet nozzle uses digital fly-by-wire control, and the direct drive force is still hydraulic.

Relying on this vector nozzle, this Su-35 fighter aircraft has become a super maneuverable aircraft. However, its shortcomings are also obvious. The biggest shortcoming is reliability!

This system is far more complicated than the binary nozzle, and even the Americans did not adopt it after comparing it. In later generations, Russia promoted it everywhere, but in the end only Asan, who liked high-end equipment, introduced it. Although the Russians swore that the life of this nozzle was 250 hours, and would eventually be extended to 500 hours. However, when Asan was using it, he found that it had to be replaced after more than 20 hours of use, otherwise various malfunctions would occur.

The solution given by Russia actually required Asan to provide more funds. Perfect work for vector nozzles. ?

Even the vector nozzles developed in later generations are at this level, let alone now. In order to promote the Su-27, the Soviets installed this nozzle to show mobility, but the reliability of this nozzle is too low, almost It had to be replaced after ten flying hours. Although it had been replaced with a new one when I arrived, it still broke down!

The Soviets have no claim to protecting their aircraft, especially the current test pilots, who are piled up with gold. They would never put themselves in danger.

After discovering that the tail was on fire, Ishakov had no intention of taking control of the aircraft.

Because, with constant maneuvering. His height above the ground has been getting lower and lower, and now, it is almost less than 80 meters above the ground! Moreover, the attitude of the aircraft was tilted, at least thirty degrees!

Eject, eject! Ishakov brought his legs together and pulled the red handle between his legs.

"Bang, with a crisp sound. The canopy-breaking gun penetrated the canopy and penetrated four holes in the top canopy. Then, the rocket below began to ignite, and the seat fixation system automatically started, pushing Ishako The husband was fastened to the seat, and at the same time, Ishakov felt his shoulders, waist and legs being tightened.

Immediately afterwards. Overhead, the ejection seat had shattered the canopy. Amidst the flying glass, Ishakov, who was tightly fixed on the seat, had already flown out of the cockpit.

And this time. The attitude of the aircraft is changing rapidly, and it has become upside down!

It's over. This Soviet man must be dead! In this case, even if it ejects, it will be head-first, and it will not be able to open the umbrella in time before it will hit the ground!

Most of the people present were from the Air Force and knew the dangers of ejection. In this situation, there was absolutely no possibility of survival!

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

This ejection seat also has two attitude adjustment rockets on the headrest, with the nozzles pointing to both sides; when the fighter is in a rollover ejection state, the downward attitude rockets will be activated to help the ejection seat change direction and move upward. Fly to get a greater parachute height. Relying on the optimization of parachute deployment procedures and active attitude control capabilities, the low-altitude inverted 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!

Just like that, under everyone's gaze, the ejection seat completed a graceful turn. After the posture was adjusted, the two stabilizing umbrellas in the two casing connecting rods on the back of the seat immediately opened to ensure that the seat Stable, at the same time, the attitude was adjusted to the vertical direction, and it continued to fly upward under the influence of the rocket thrust.

The posture stability of this K-36 seat is very good, which is due to the two 1.8-meter-long stabilizer bars at the back and the rotatable stabilizing umbrella system. The two stabilizer rods extend 15 degrees based on the heading, so that the stabilizer umbrella is outside the turbulent area behind the chair; no matter how the posture changes, there is always one stabilizer function in a strong and effective state, which can quickly adjust the seat. Pull back to normal posture. In this way, this ejection seat can always maintain an "upright" state.

After the rocket engine at the bottom stalls, it is already high enough in the air. Then, the seat is separated from the person and the main parachute is opened!

Orange and white umbrella flowers appeared in the sky, and everyone opened their eyes wide again. Oh dear, this umbrella is not sewn tightly!

The parachute of the K-36 ejection seat adopts a slit structure, with 8 symmetrical slits to achieve dual-mode operation at high and low speeds: the slits are very small at low speeds, and the characteristics of the life-saving parachute are close to those of unslit and unclosed parachutes. In this way The parachute has large resistance, fast deceleration, and can carry out safe lifesaving at a very low altitude. At high speeds, the slits will be forced open under the air pressure generated at high speeds, directly expelling part of the airflow 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 kilometers per hour. At the same time, the HTY-5 used by the J-10 has a maximum parachute opening height of 4,000 meters and a maximum parachute opening speed of 600 kilometers per hour. As for the HTY-6 seats used by second-generation aircraft such as Feibao and J-8, the maximum opening height and speed are only 3,000 meters and 520 kilometers per hour.

Everyone's eyes were fixed on the parachute, not paying attention to the fighter jet that had fallen to the ground. The Soviet Union's only thrust vector Su-35 fighter jet was almost always given the internal number of Su-37. , and it crashed.

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

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

Every performance performed by the Soviets greatly shocked the people present, but those dazzling performances were not as shocking as the current ejection escape!

Although China's economy is still very weak and the financial resources the country can devote are limited, it must not be stingy in certain aspects! If a domestic fighter plane were to encounter such a dangerous situation, it would definitely be destroyed and everyone would be killed! The Soviet ejection seat allows the pilot to escape in such a situation! This ejection seat technology must be introduced! It would be best to get a few ejection seats and have them copied by domestic manufacturers!

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

Mhammad's eyes were opened today. Mhammad, who comes from a later generation, naturally knows that the performance of the ejection seat of the Soviets is simply too good, so good that the Americans have imported some. This ejection seat has become a star at previous air shows. Not to mention, most recently, at the Paris Air Show in 1989, a Soviet MiG-29 fighter jet crashed due to a collision with a bird. The pilot succeeded when the aircraft was 90 meters above the ground and almost vertical. Ejection was rescued and his face was revealed to all the West.

In later generations, in 1993, two MiG-29s collided and crashed during a flight display at the Paris Air Show. At the Paris Air Show in 1999, the Su-30МК two-person ejection from almost zero altitude, and the Ukrainian Air Force Su-27 flight show accident in Lviv in July 2002, the pilots escaped safely in extremely dangerous situations. Especially in the accident in 2002, the Su-27 exploded after touching the ground. The fireball rolled into the crowd. In the pilot's graceful ejection, 83 people on the ground were killed and more than 100 people were injured.

The K-36 ejection seat almost never goes wrong and is the best guarantee for Crazy Ivan. In comparison, the American's ejection seat is much worse. Historically, in the 1991 Gulf War, ejection escape Four of the 16 US military pilots suffered spinal fractures, and only seven were completely unharmed after jumping to the ground.

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

"Ishakov, it was your wrong operation that caused this accident!" Gorishin said immediately after seeing Ishakov who was unharmed, while winking at Ishakov.

You can't admit it's an aircraft defect, right? It's not a defect in the aircraft, it's a problem with the personnel's operation! Therefore, Gorishin immediately made a conclusion and hoped that Ishakov would admit it.

Unexpectedly, 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 piss Gorishin. Even Simonov is not afraid of technical problems. It is obviously a vector nozzle failure! (To be continued ~^~)
