To provide desired engine restart capability and limit ignition operating time to minimum, development of flameout sensor was considered; compressor discharge pressure (CDP) was used as most desirable sensing parameter to obtain positive indication of flameout; sensor is pressure sensitive switch actuated by 3-lb differential in air pressure between 2 chambers, separated by snap-action-diaphragm; sensor actuates ignition in less than 0.1 sec and "ON" time for ignition is controlled by duration of 1-lb pressure differential; schematic diagram; results of flight testing.
