Abstract

We begin by analysing a situation that might imply an ejection at low altitude and if the aircraft goes at a high speed this would imply the use of two auxiliary drog chutes that would open in sequence to brake the pilot before the opening of the main chute. We design the two drog chutes and main chute to guarantee an initial deceleration less than -40g and a descending speed of 25km/h when the main chute is opened. Finally we show our technical solution, the hybrid circuit OpenChute, that controls the opening of the two drog chutes in sequence and the main chute based on high quality sensors of speed and altitude that the ejection seat must has and we show that with our solution we could make ejections at very low altitudes until the speed of 400Knots.
