Occupant Ejection Response Analysis of Front vs. Rear Crew Station in TF-18 Aircraft.
Abstract
Due to differences in the geometry of the rear and front crew stations in the TF-18 aircraft, there is some concern regarding occupant-seat interaction in the aft crew station. Specifically, rudder adjustment in the aft location was reduced by 1.75" over that existing in the front. This reduction in rudder adjustment might affect seat-man compliance and consequently occupant response to ejection forces. A change in occupant response could compromise the effectiveness of the toe guides in reducing the probability of direct impact between the feet and instrument panel. Since all other critical clearance dimensions are the saine in the respective crew stations, the.only occupants of concern are those that require that additional 1.75" of rudder adjustment. These large individuals however, are also the ones that require the greater protection, being the ones most likely to experience foot-instrument panel contact. The questions to be answered are: (1) Is there a difference in ejection response of large individuals in the front vs. the rear crew station? (2) Can anthropoinetric limitations be specified such that the possible response differences can be obviated?
