Digital Recovery Sequencer - ACES Ejection Seats

Abstract

The ACES ejection seats currently utilize a Recovery Sequencer based on analog technology to control ejection event timing and ejection mode selection. The Recovery Sequencer has limitations with respect to installed life, electronic component obsolescence, flexibility to accommodate seat safety improvements, and mode differentiation at the Mode 1 to 2 crossover point. The Digital Recovery Sequencer (DRS) program was undertaken by Goodrich, the seat OEM, and the CAD/PAD Joint Program Office (JPO) to design and qualify a sequencer based on digital technology that overcomes the limitations of the Recovery Sequencer. The DRS Program was broken down into three phases.
