Considerable research and development effort has been devoted to improving seating in helicopters since the early 1960’s when the need for improved ergonomics and crashworthiness was first established. Yet currently a typical rotorcraft crew/pilot seat uses only passive shock absorbers for mediocre crash safety and entirely lacks systems for whole body vibration reduction. Recent advances in the active and semi-active damping systems create opportunities to improve shock absorption capability while providing rotor induced whole body vibration mitigation. In this SBIR program Materials Technologies Corporation proposes a unified hybrid actuator/shock absorber concept that provides fail-safe adaptive shock absorption with active vibration control on typical helicopter crew seats for military personnel ranging from 5th% female to 90th% male.
