the cause of the "Flying Leopard(FBC-1)" fighter bomber crash:two cases caused by the aircraft stall

On the morning of July 19, before the start of the "Peace Mission -2009" Sino-Russian joint anti-terror military exercises,an accident took place ,which a Chinese "Flying Leopard(FBC-1)" fighter bomber crashed crashed at a military training base in northeast China, two pilots of the "Flying Leopard" fighter bomber have died

Up to now, "Flying Leopard" details the process of the crash and the cause of the accident is still not clear, I believe the air crash accident investigation is still underway and interested parties on the cause of the accident analysis, evidence and the authority of a certain number of days that may be required.

"Flying Leopard" Why get out of control?

Closest to the scene of the accident and the Russian military press officers. On the 19th day, Russian media quoted Russian military sources said the crash of the "Flying Leopard" fighter is ready to fight against a ground target, at a distance of 200 meters high ground lost control and crashed and exploded, killing two on board the death of the Chinese air force officers . Preliminary analysis of the Russian side believes that the crash was involved in the operation of machine error.

However, in the final before the announcement of the findings, a number of reasons are possible.

It is reported that the "Flying Leopard" before the crash in the "stall" state. "Stall" refers to aircraft in flight beyond the normal range due to angle of attack, causing the wing to lose lift. For high-speed movement of the aircraft, lost in the 200 meters height of lift is very dangerous. At that time, "Flying Leopard" was about to attack ground targets, if possible, there are two types: one is so ready to dive, such as firing rockets and ammunition, but the dive angle, and excessive speed caused the crash of the aircraft out of control; was also the case of the plane fell prepared to do to a certain height bomb action, when the pilots suddenly found a high degree of low, so hurry up, take onto the aircraft after a certain point of the top wing air anomaly, lift, so the crash; there may also be a can not be ignored, that is, abnormal flow near the plane caused by abnormal posture, or inhalation of foreign bodies or crash the aircraft engine air intake, which may probably be caused by the accident aircraft.

Why did not the pilot ejected?

Crash, the most grief is the unfortunate death of two pilots. "Flying Leopard" fighter ejection seat has a good feature, why pilots do not escape in time?

"Flying Leopard" is a serial two-seater cockpit structure, the front seat pilot is responsible for manipulation of the aircraft, the back seat of the pilot in charge of navigation and manipulation of weapons. Russian pilot error caused speculation that the crash, but this is only speculation. Height and angle of the aircraft caused by abnormal, out-of-control plane may be a variety of reasons, there may be two with the improper operation of negligence, but also may be caused by the aircraft instrumentation display pilot misjudgment.

But in any case, when the plane got out of hand, the crew should be able to feel, for example, the joystick caused the aircraft stall severe jitter, such as body tremor. At this point, the pilot can choose to abandon aircraft parachute. "Flying Leopard" fighter cockpit with 2 HTY-2C command procedure type two-seater mid ejection seat, according to the theoretical design of such a seat can be ejected at 0 height, chair of the rocket through the pilot ejected to a certain height , and then open a parachute from the realization of the pilot landed safely.

Pilots have no choice but abandoned aircraft parachute that at the last minute they want to try to save the aircraft, only 200 meters left to decrease the high-profile aircraft correction, too little time to restore control, the pilot has not had time to remedy.

Reflect the lack of support system crash

200 meters high is a focus. In actual combat, fighter planes flying to 200 meters high, not only will many of its own flight control the risk of accidents and the threat of enemy air defense firepower will be very great. Even though they do not have anti-aircraft missiles, armored vehicles, bringing the use of air guns, cannon to shoot down aircraft will effectively injuries. "Flying Leopard" fighter of the seats have a bullet-proof steel plate, the lower part of the cockpit and the fuselage fuel tank has a bullet-proof composite armor, but the 200 meters in height and can not be completely blocked anti-aircraft machine gun fire.

Exercise is to simulate actual combat, combat in "Flying Leopard" it is necessary to fly so much that you? Some analysts believe that "Flying Leopard" attacks in the implementation of the mandate of the use of sea-air-to-ship missiles, guided missiles and other flying ships to attack the target accurately, the pilot operation of complexity is relatively small, but the attacks in the implementation of tasks, " Feibao "supporting the lack of precision-guided munitions. The use of rockets, low-precision cruise missiles or cannon against ground targets, such as when to play accurate, the aircraft had to fly low point, slow down, which not only make more complicated the work of two pilots, and the event of an accident to the pilot to make response time less.

In addition, the low air-to-surface attack also reflects the "Flying Leopard" behind the C3I (command, control, communications, intelligence) system, lack of support. "Flying Leopard" in the exercise accompanied by a lack of real-time battlefield intelligence guidance and support, the positioning of ground targets the information needs to get its own planes, ammunition which itself has no precision-guided devices, the two machines must be tight to control the aircraft to find the target, grasp launch time, this pressure to the pilot too much, easy to strike a balance. Modern air combat combat units should be through the combination of operations to form a whole. From the "Flying Leopard" crash, the various operations of the joint integrated units is still not high enough.

"Flying Leopard" background

"International Herald Tribune" article "Flying Leopard" said Foreign FBC-1, NATO code-named "halibut." Zhuhai Air Show in 1998 on the debut, in 2007 the Chinese People's Revolution Military Museum of Art. Western believes that the People's Liberation Army is equipped with a total of about 100 "Flying Leopard", and in recent years on the "Flying Leopard" to replace the radar, cockpit systems, a slight adjustment of the local wing, stealth coating machine for coating the outside world that this improved the "Flying Leopard" for "Feibao A", the Russian news of the crash is that the modified "Flying Leopard."

"Flying Leopard" due to China in the last century, the beginning of 70's R & D -5 H -5 and strong follow-up models. It is said that the demand for this equipment is because in 1974 Xisha lessons learned after the war, the People's Liberation Army that there was an urgent need for a voyage,loading number are large enough, both fighter and bomber combat aircraft performance.

In order to meet China's vast sea and air combat needs, the requirements of this aircraft can attack on the sea, but also a certain degree of air combat ability. That is to say "Flying Leopard" it is necessary to be able to use bombs, missiles, bombing, attack the sea or ground targets, shoulder-depth attack campaign, but also through the air-to-air missiles, cannon and other self-defense and air combat. "Flying Leopard" have been given targets of the enemy's main transport hub, sea and air bases, beachhead, the enemy forces, as well as assembly points in surface ships. "Flying Leopard" in the attack can be mounted anti-radiation missiles, laser navigation system shells, general aviation bombs, rockets and so on.

"Flying Leopard" it crashed deep in the accident, but that does not mean that "Flying Leopard" fighter's performance problems. Fighters and civilian aircraft of different exercises and training needs to be done is often difficult, high-risk moves, which the body of the aircraft and pilot tests are harsh. Therefore, the Air Force from the more difficult and strict focus on combat training, the situation in the event of an accident the more. For example, in 2008 a high incidence of accidents during the U.S. Air Force, F-15, F-22, B-2 crash occurred one after another, F-15 or even fully grounded once. For this reason, in recent years, China's fighter training in the normal exercise of the accident to take a more rational and transparent. Summer 2008 collision of two planes crashed -8 F, the spring of 2009 F-1 -10, such as air breakdown successfully made an emergency landing, which are made public soon. These "negative" reports, not only did not affect the image of the Chinese air force, they contribute to the outside world of China's Air Force has a more objective and comprehensive understanding.
