Ejection seat

Compression fractures of vertebrae are a recurrent side effect of ejection. It was theorised early on that ejection at supersonic speeds would be unsurvivable; extensive tests, including Project Whoosh with chimpanzee test subjects, were undertaken to determine that it was feasible. Many aircraft types e. After World War II, the need for such systems became pressing, as aircraft speeds were getting ever higher, and it was not long before the sound barrier was broken. In this form of the invention a hollow conical-shaped housing 53 is inserted between and rigidly secured to the mounting end 49 and the ignition portion 50 to provide an integral unit which as designated is referred to as the jet perforator and igniter Some operate like a standard ejector seat, by jettisoning the canopy, then deploying a drag chute into the airflow.
