Abstract : Equipment was designed to measure the opening load on the shroud lines of a Parachute, Mk. 2 Mod. 3, attached to a Mine, Mk. 25, Mod. 1, and to telemeter the information to a ground recording station. It is concluded that the telemetering equipment provided satisfactory transmission of opening load measured by strain gages mounted in the shroud lines of a mine parachute. It is recommended that the equipment be adapted to multi-channel use and further drops be made to determine opening load on individual shroud lines under various conditions of release speed and opening delay.
