Abstract
A parachute deployment actuator incorporating an aneroid with a relatively long strike results in a significant diminution in the degree of precision with which the associated parts have to be made. A spring is provided externally of the aneroid in such relationship as to augment the natural spring force tending to expand the aneroid, such spring operating not only to keep the aneroid off its internal stop at sea level but also to cause the overall system to have a desired spring rate. A variable lever system inter-relates a preprinted scale and associated altitude cam with the aneroid in such relationship that the parachute actuator will release the chute very near a pre-set altitude.
