Study to Determine the Application of Aircraft Ignition-Source Control Systems to Future Army Aircraft.

摘要

The report presents the results of a program that was conducted to provide design information applicable to future Army aircraft relative to crash sensors,ignition-source suppression systems,and circuitry for the automatic activation of the suppression systems. The program involved a comprehensive literature search,the development of requirements for the initiating subsystem of the overall ignition source control system,and the consideration and comparison of several illustrative activating circuits. The development of a workable ignition-source suppression system was found to be feasible. Several systems have already been developed to cool hot surfaces,to inert atmospheres,and to de-energize electrical systems. The areas of the ignition-source control problem which require development are: the selection and the degree of redundancy of crash sensors,the locations of the sensors on the aircraft,and the complexity of the activating and control circuitry.
