Aircraft Hazard Detection and Control Utilizing an Aircraft Data Acquisition System.

摘要

This report summarizes the results of an in-house program which demonstrates the feasibility of using an aircraft multiplexed data acquisition system for on-board aircraft hazard detection and control. The hazards of primary interest are fire, explosion, overheat, smoke, and explosive vapors. Hazard control involves system shutdown as well as activation of extinguishing systems and other active protective systems. This program involves both concept formulation and the design of breadboard hardware to demonstrate these concepts. Advanced aircraft will have multiplexed data acquisition systems with central computers for a variety of applications. Hazard detection is shown to be a small part of the total aircraft data system requirements. It is shown that hazard detection subsystem complexity and cost are reduced by using a data system and computer on a time-shared basis. (Author)
