Embodiment Construction

[0055] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0056]The helicopter has propellers on it, so if you eject upwards to escape, you need to avoid the impact of the propellers. Under normal circumstances, the helicopter generally flies forward. If it is ejected to the sides of the helicopter to escape, since there are no helicopter seats on both sides to rely on, it is neither in line with the science of human body force, nor in line with the principle of using the speed of the aircraft to stay away from the body. Therefore, in order to make better use of the forward flight speed of the helicopter, you can choose to eject forward to escape.

[0057] See attached Figure 1-3 , a kind of helicopter of the present invention comprises:

[0058] Body 3;

[0059] a cockpit 1 detachably connected to the body 3;

[0060] A connection protection device that is provided at the joint 2 between the body 3 and th...

Abstract

The invention discloses a helicopter and an ejection escape buffering device, belongs to the technical field of helicopter escape devices, and aims to solve the problems of complex ejection processes,low safety coefficient and poor protection performance during crashing of helicopters in the prior art. The helicopter comprises a fuselage, a cockpit detachably connected with the fuselage, a connection protecting device which is arranged in the connected position of the fuselage and the cockpit to realize connection or separation of the fuselage and the cockpit as well as a separation bufferingdevice arranged in the position, close to one end of the connected position of the fuselage and the cockpit, of the cockpit; and the falling and landing speeds of the cockpit are reduced under the action of rocket catapults and parachutes of the separation buffering device.

Description

technical field [0001] The invention belongs to the technical field of helicopter escape devices, and in particular relates to a helicopter and an ejection escape buffer device. Background technique [0002] For helicopter safety protection measures, different means have been adopted in the prior art; as installation of ejection seat, anti-roll cage design, cushioning structure of helicopter seat and safety airbag. [0003] As for ejection seats, among the many helicopters in the world, only the Ka-50 and Ka-52 helicopters are equipped with ejection seats. The reason why other helicopters are not equipped with ejection seats is because the structure of the helicopter is relatively special. The top of the cockpit is the rotor, and the ejection is more complicated. In addition, helicopters generally fly at a low altitude. If there is a mechanical failure during the flight or if they are hit by an enemy weapon and lose control and cannot fly, the complex ejection process is pr...
