Attenuation of Biological Stress from Combined Vibration and Acceleration by Use of Pressure Breathing

Abstract

The complex launch and reentry environment of future manned spacecraft and the associated crew stresses resulting from exposure to the dynamic loads are analyzed. The analysis provides a strong theoretical basis for predicting significant increases in crew stresses from vibrations in future space operations. The biomechanics of g, vibration and hypobaric stress summation are identified. Techniques designed to attenuate the independent and combined stresses are presented along with the theoretical grounds for postulating the protection concepts. Recommended techniques include use of positive pressure breathing and increased space cabin environmental pressure.
