Description
L R Poole of the Langley Research Center presented this parachute program in August 1972, as NASA TM X-2592. His surname is poorly rendered in the scan. A parachute's lines stretch as it snaps open, and that stretch shapes the opening shock. Poole's program studies how uneven line stretch changes inflation loads and motions. Designers of recovery systems needed such predictions. A wrong guess could tear a canopy or overload its load.
The program joins two models together. A mathematical model captures the elastic layout of the suspension lines. That model couples to flat motion equations for a general parachute system. Users can then test different line materials and layouts safely. Each run shows the resulting loads and flight path changes. The approach served capsule and probe recovery design.
