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.
