Abstract
The dynamic stability of a parachute load system has been analytically investigated for a pointmass load and a statically stable parachute. A typical system consisting of a relatively large suspended load mass and small ribless guide surface parachute has been numerically calculated. Utilizing the apparent mass and apparent moment of inertia, as well as the aerodynamic coefficients of the parachute canopy, the equations of motion for the system have been solved. The influence of several design parameters upon the dynamic stability characteristics of the system have been discussed.
