Abstract

This report presents the results of a limited parametric study of ten space package alightment systems. A state-of-the-art review in alightment dynamics was conducted prior to beginning the parametric study. Two three-dimensional digital simulations were developed for use in the parametric study. Each of these simulates a basic design concept of an alightment system. Two types of alightment systems were examined. One for a 300 pound capsule with electronic cargo and one for a 3000 pound capsule with human cargo. An experimental program was performed to permit a comparison of predicted and measured acceleration time histories during alightment. Generally, excellent correlation was shown. Energy absorbing material or techniques are shown to be a secondary consideration in determining the efficiency of an alightment system. A three-dimensional digital simulation of alightment dynamics is concluded to be mandatory in the development of an alightment system. The feasibility of an alightment system, weighing 6 percent of the total capsule weight, to alight successfully on a 35 degree slope with a 12 degree capsule inclination is shown. Such a system is capable of handling a vertical velocity of 35 feet per second and a horizontal velocity of 15 feet per second.
