ACES 2 Negative Gz Restraint Investigation
Abstract
Seven human subjects, and 5th and 95th percentile male manikins were subjected to -Gz conditions on a man-rated centrifuge to test the restraint effectiveness of the ACES II restraint system used on the A-10, F-15, and F-16. The restraint was tested with shoulder straps locked, unlocked, and unlocked with the addition of a tiedown strap connected between the lap belt and the floor. A -1 Gz condition was created by inverting the centrifuge cab for 30 seconds. Human subjects were exposed to levels of -1.5 and -2 Gz for 20 and 10 seconds respectively by rotating the centrifuge arm. Manikins were similarly exposed to levels up to -5 Gz. Off-seat displacement was measured directly by a unique spring-loaded transducer mounted in the seat pan. Lap belt and tiedown strap forces, and tracking and ejection task performance were also measured.
