Study on the influence of explosion impact on pilots in ejection

Abstract

The principle of two kinds of hatch break system and hatch cut-and-drop system for aircraft ejection path clearing with fireworks are introduced. The blast wave produced by the fireworks is transmitted in two forms, one is in the form of stress wave in the structure it is installed, the other is in the form of air expansion wave in the air, and affects the structure of the aircraft and the electronic instruments fixed in the structure, the auditory and non-auditory organs of the pilot. At present, the damage limits of the pilot's auditory and non-auditory organs are given according to the specific scene, in national military standard and U. S. military standard. At the same time, the related research results are also given by scholars at home and abroad. In view of the impact of ejection explosion impact on pilots, the research on this problem in the domestic life-support field is basically blank. At present, some important advanced combat aircraft which have adopted or planned to use firework for ejection path clearing are not clear about this problem. Based on the current situation of domestic research, this paper puts forward the follow-up work to be carried out.
