Opening Dynamic Characteristics of a 32-Ft Ringslot Parachute, Stiffness Index 0.24, and 45.2-Inch Model, Stiffness Index 0.40

Abstract

The stiffness characteristics of full size and model parachutes can be expressed as stiffness indices. A very flexible model was developed with 0.4 stiffness index while a geometrically similar 32-ft ringslot parachute had an index of 0.24. The design details of the flexible model are described. The projected area-time history during the inflation of the 32-ft ringslot parachute, obtained from full size parachute tests, was compared with those of the model ringslot parachute with a stiffness index of 0.40. The area-time characteristics of the model were obtained in wind tunnel tests.
