Abstract:

A description of the eye-level blood-pressure response to G sub Z stress in relaxed humans was obtained as an empirical, ensemble-average, G-to- blood-pressure transfer function based on 3 subjects responses to a total of 23 simulated aerial combat maneuvering runs on the USAFSAM Human Centrifuge. Three different analytic transfer functions were fitted to the empirical function for frequencies from 5 to 200 mHz, and predictive performance of the empirical and 3 analytic functions was examined. The double-zero, double-pole mathematical model most closely fit the empirical transfer function and displayed reasonable predictive ability.
