CONTROL PERFORMANCE UNDER ACCELERATION WITH SIDE-ARM ATTITUDE CONTROLLERS

Abstract

This paper presents procedures, data, and conclusions based on closed-loop centrifuge experiments in which side-arm controllers were used by pilots to perform specific control tasks. Under certain conditions the pilots could perform as well in adverse acceleration fields as they could statically, even though they were exerting more physical effort and psychological concentration, and were enduring visual impairment, chest pains, breathing difficulties, and other stressful effects of acceleration. The pilots demonstrated a remarkable ability to adapt to physiologically severe acceleration environments, and they maintained control performance within acceleration time history profiles which contained vectors with amplitudes as high as +15 G (chest to back), -7 G (back to chest), and +7 G (head to foot). Some closed-loop human centrifuge simulations were conducted which provided human factors data which may have application to the design and evaluation of side-arm controllers for use within proposed space vehicles.
