To investigate injury of windblast at high speed,flow around a seat occupant is simulated in a scale adaptive simulation turbulence model. Numerical simulations agree well with wind tunnel experiments at Mach number 0.6 and angles of attack from -90° to 90°. Flow around seat occupant without protection is simulated. Injury of pilot during high speed ejection is investigated. It shows that high pressure zones load on pilot are face,thorax,abdomen,inside of upper arm and windward side of calves. As pitch angle increases pressure distribution on each part can improve.
