Study on the Electromagnetic Environment of the Inner and Outer Fuselage and the Hazard of the Environment to Electro-Explosive Systems

Abstract

To meet the air emergency evacuation needs of aircraft flight test team members, we developed the air emergency opening system of aircraft service port. During the flight tests, the probability of false triggering of the electro-explosive system used in the emergency opening system is called for not more than 0.001 in the confidence of not less than 90% under the interference of external electromagnetic radiation, and when the aircraft experience an emergency, the electro-explosive system can work reliably according to the preestablished instructions to detonate the detonation power unit of the emergency opening system, and the service port will be pushed into the cabin fast and accurately, so that the aircrew could bail out of the aircraft by the barrier-free access. Therefore, this paper examines the electromagnetic radiation environment of the inner and outer fuselage of the aircraft, and then analyzes the hazard of the electromagnetic environment to the electro-explosive system of the emergency opening system as a base for the safety design of the anti-electromagnetic radiation of the emergency opening system.
