Abstract
An automatic line release system for severing parachute suspension lines at a pre-set time in order to evaluate parachute performance under controlled conditions. The line release system utilizes an electronic timer and switching circuit to energize strands of wire ("burn" wire) wrapped about the desired suspension lines at a point near the riser connector links to burn through the lines and thereby release them.
