Power source for an electroballistic sequencing system.

摘要

Start-up electrical power modules (10) are utilized in electroballistic sequencing systems for initiating the ballistic sequence necessary for seat and canopy ejection in military aircraft. The power modules (10) utilize aircraft power to initiate the ballistic sequence necessary for ejection of the pilot or pilots. The power module (10) also comprises two independent internal power supplies (18,20) as back-up power sources in the event of total aircraft power failure. The power modules (10) are activated by the manual pulling action of an actuation shaft (22) by the pilot or by the automatic pushing action of the actuation shaft (22) by a piston once the pilot initiates the ejection sequence. Once the actuation shaft (22) is pulled into an armed position, dual switches (14,16) are activated thereby supplying electrical power from the aircraft or from the back-up power sources (18,20) to a signal conditioner and controller (12). The signal conditioner and controller (12) processes the signals and outputs a single direct current signal to a ballistic sequencer (52).
