Analysis of Personal Thermal Control System (PTCS) on Head-Spine Structure Ejection Dynamics.

摘要

Head-Spine Model (HMS) ejection simulations have been conducted for the purpose of determining what effects a personal Thermal Control system (PSTCS) Headliner Vest will have on occupant dynamic response during ejection. Only the inertial effects of the headliner and vest were considered. Three simulations were run: without any inertial loading of the headliner and vest; and with inertial effects included for two possible vest locations. The prescribed acceleration profile used in the simulations approximated the first 250 msec of a severe H7 seat (used in some F-4 aircraft) acceleration profile. Results demonstrated that the PTCS had negligible effects on the dynamic response and injury potential of the head-spine system.
