Improving Inflight Negative Gz Restraint for Aircrewmen.

Abstract

Inadequate negative Gz restraint has been cited as a factor preventing pilots from recovering control of their aircraft after a departure from positive G maneuvers. Several prototype XV seat-mounted harnesses were designed and tested to determine if they might provide improved inflight restraint. Although they were able to improve restraint, none of them could meet the rigid and conflicting demands which were imposed. The restraint which met most of the requirements was the MA-2 Torso Harness with the addition of a seat-mounted 'Y' shoulder strap. The 'Y' strap reduced average head displacement to about one-third of its former value (from 6cm to 2cm for a 50% subject at -1Gz). No problems were uncovered during seat/man separation tests, and the 'Y' strap did not restrict upper torso rotation. Originator-supplied keywords include: Restraint, Inflight, Negative Gz, and Aircrewman.
