The American Black Hawk helicopter adopts full cushioning, which is an ordinary semi-hard shell light alloy crash-resistant structure. Four longitudinal keel beams are connected with four main load-bearing frames. The vertical collision speed of the cockpit is11.5m/s. The fuselage can also withstand the collision of 20g forward and 10g downward. In other words, helicopter wheel brackets and seats can play a buffering role, thus improving the survival rate. The survival rate of Black Hawk helicopter members is 85% when the landing speed is 1 1.5m/s ... This is also the method used in helicopter escape in Europe and America.
At present, only ka50/ka52 use ejection parachutes to escape, that is to say, before parachuting, it is necessary to throw away the propeller, then throw away the umbrella cover, and then fire the rocket ejection seat for parachuting.
