Abstract
An ejected pilot's seat is provided with a drogue chute anchored to the seat by means of a bridle. The bridle includes a strap having redundant load cells parallel connected in redundant fashion. The load cells measure tension in the strap. Data from the load cell is conducted through the bridle to a microprocessor contained within the seat. The microprocessor includes look-up tables for correlating tensile load in the strap to forward velocity of the ejected pilot. Upon acquisition of a preselected optimum velocity, the drogue chute is released and a main chute is deployed to increase the likelihood of a safe descent to the ground.
