An escape parachute chair for manned unmanned aerial vehicles and helicopters

Abstract

The invention relates to the field of low-altitude escape in aircraft, and more specifically relates to an escape umbrella chair for a manned unmanned aerial vehicle and a helicopter. The escape umbrella chair for the manned drone and the helicopter comprises a foldable inflatable seat, an inflatable bottle, an inflatable valve, a fixing belt, a fixing frame and a power storage device. The foldable inflatable seat includes a first form that is folded into the appearance of an aircraft seat and a second form that has the appearance of a parachute after being inflated. The foldable inflatable seat is connected to the body through a power storage device, and the power storage device is used to eject the foldable inflatable seat. out of the body. The invention provides an escape umbrella chair for manned drones and helicopters, which can avoid the problems in existing low-altitude escapes, ensure the safety of escape personnel, and is suitable for multiple use of manned drones, helicopters and rotorcraft. This method is easy to maintain, maintain and replace without modifying the structure of the aircraft. In addition, it also has the advantages of simple operation, low manufacturing cost, strong practicability, light weight and recyclability.

Description

technical field [0001] The invention relates to the field of low-altitude escape in aircraft, and more specifically relates to an escape umbrella chair for a manned unmanned aerial vehicle and a helicopter. Background technique [0002] The common aircraft escape schemes are as follows: [0003] 1. Autorotor. The conditions required for autorotor escape include that the aircraft must reach a certain height, and then keep the body level to land. When approaching the ground, use the rotor to generate a certain lift, then land horizontally, and use the body buffer to achieve the escape effect. It has many disadvantages: (1) When the aircraft fails, it is difficult to maintain a horizontal attitude; (2) The flying height of the aircraft is not enough, and the lift force pulled up instantly when landing is insufficient, so the purpose of escape cannot be achieved; (3) The aircraft and the ground The distance between them is difficult to grasp. If the lift is too high from the gr...

It has many disadvantages: (1) When the aircraft fails, it is difficult to maintain a horizontal attitude; (2) The flying height of the aircraft is not enough, and the lift force pulled up instantly when landing is insufficient, so the purpose of escape cannot be achieved; (3) The aircraft and the ground The distance between them is difficult to grasp. If the lift is too high from the ground, the lift will be wasted, and if the lift is too low, the lift will not be enough, resulting in the effect of direct landing. It will test the pilot's psychological quality and reaction speed, especially for transport helicopters, whose instability will Further improve

Its disadvantages are: (1) The helicopter needs to land horizontally, and it is not easy to maintain a horizontal attitude when the aircraft breaks down. (2) People in the aircraft without cushioned seats are more likely to be injured. Injuries to the personnel inside are relatively large, resulting in the loss of action and combat capabilities

[0005] 3. Rocket ejection escape, the disadvantage of rocket ejection escape is that there are too many steps. Taking the Russian Ka-52 as an example, the helicopter rotor needs to be blown up first. The rocket seat ejection escape can only be implemented after the helicopter canopy is blown up, and the helicopter rotor is rotating at a high speed Breaking away from the aircraft will cause direct damage to nearby friendly forces, so the formation of friendly forces must be 150 meters or more larger than the escape plane, otherwise it is easy to accidentally injure friendly forces, and it is also costly and difficult to maintain.

Its disadvantages are: (1) Helicopters generally fly at a low altitude, so most of the time the altitude is not suitable for escape by skydiving, and it is easy to land before the parachute is opened. (2) It takes a certain distance to complete the parachute Unfold, if the parachute is opened too early, it is easy to be pulled by the chaotic airflow under the helicopter, so that the canopy cannot be deployed quickly or the parachute rope is entangled, resulting in the failure of escape
