Computer Program for Investigating Effects of Nonlinear Suspension-System Elastic Properties on Parachute Inflation Loads and Motions

摘要

A computer program is presented by which the effects of nonlinear suspension-system elastic chaachute inflation loads and motions can be investigated. A mathematical elastic model of suspension-system geometry is coupled to the planar equations of motion of a general vehicle and canopy. Canopy geometry and aerodynamic drag characteristics and suspension-system elastic properties are tabular inputs. The equations of motion are numerically integrated by use of an equivalent fifth-order Runge-Kutta technique. (Author)
