Abstract:

The influence of horizontal wind shear layers upon descending, statically stable parachutes has been studied analytically and experimentally. The investigation is concerned with horizontal displacements, response velocity response time, and angle of attack. For comparison, experimental were conducted with two circular flat ribbon, two ringslot, and one ribless guide surface parachute model. The results show that the analytical predictions are a satisfactory first approximation of the observed performance characteristics. Author
