AIRCRAFT FUEL TANK EXPLOSION PREVENTION AND SMOKE ALARM RESPONSE SAFETY IMPROVEMENT METHOD

摘要

A method for preventing aircraft fuel tank explosion and increasing smoke alarm time warning that can be newly manufactured or retrofit to existing aircraft systems. Pressurized conditioned or unconditioned cockpit-flightdeck-cabin waste outflow air or atmospheric ambient air medium (9) is provided to circulate air in the unoccupied areas of the aircraft to purge and remove fuel tank fumes from within the fuel tank and heat outside the fuel tank and to actively move air in the smoke-alarmed areas (2) of the aircraft for faster alarm-detector response time. The purge exhaust is vented to the engine or APU intake or bypass airflow to the atmosphere.
