Modeling of Whole-Body Response to Windblast

Abstract

The Articulated Total Body (ATB) Model was modified for improved modeling of the biomechanics of the man/seat ejection problem. The new ATB-IIIA version of the model incorporates whole-body wind tunnel data to model windblast, an improved algorithm to simulate the ACES-II STAPAC assembly, and calculates the location of the instantaneous center-of-mass for either the man or the man/seat system. The enhanced ATB Model provides for the modeling of the ACES-II ejection sequence from initiation of ejection to man/seat separation. The data for several ejection simulations are provided and discussed in detail. An extensive literature search was conducted in the area of ejection, windblast response and restraint systems. A summary of pertinent reports and available wind tunnel data is provided, as well as recommendations for future wind tunnel testing to correct for deficiencies in currently available aerodynamic data.
