Evaluation of Physiological Inputs to High G Performance Models.
Abstract
This report presents a review of physiological model structures and recent acceleration studies that are applicable to the problem of modeling the response of the human cardiovascular system to +Gz acceleration. A recently published model of cardiovascular response is analyzed as a closed loop control system. Certain problems associated with the direct simulation of such models are identified, and methods of removing these difficulties are considered. A revised model is derived, and the results of preliminary analysis and simulation of this model are presented. A discussion of the physiological aspects of developing an improved model is included, and the next steps toward implementing this model are outlined. A brief synopsis of several recent relevant acceleration studies concludes the report. (Author)
