MIL-DTL-85097C, DETAIL SPECIFICATION: USN/USMC PROPELLANT ACTUATED DEVICES (PADs), GENERAL SPECIFICATION FOR (30-OCT-1997) [SUPERSEDING MIL-A-85097B]

MIL-DTL-85097C, DETAIL SPECIFICATION: USN/USMC PROPELLANT ACTUATED DEVICES (PADs), GENERAL SPECIFICATION FOR (30-OCT-1997) [SUPERSEDING MIL-A-85097B]., This specification covers the requirements for propellant actuated devices (PADs) used in aircrew escape systems. The requirements common to all such devices are in this specification; requirements unique to individual PADs are in the associated detail specifications, listed in Supplement 1 of this specification, and take precedence over this general specification. The aircrew escape propulsion system is composed of a variety of propellant actuated devices that when sequentially activated provide for aircrew safety during an emergency egress. Units such as catapults or the catapult phase of a rocket catapult will propel the ejection seat and its occupant out of the aircraft. Units such as under seat or seat back rocket motors or the rocket phase of a rocket catapult will propel the ejection seat and occupant safely away from the aircraft. Other rocket motors provide reactive impulse for seat subsystems such as man-seat separation, seat trajectory modification, canopy jettison, or parachute deployment. The system will propel the occupant of the seat at a sufficient velocity to ensure that he will clear a fast moving aircraft by a safe margin and attain a height required to permit parachute deployment and a normal and safe descent. The specific intended use for a particular unit will be described in 6.1 of the individual associated detail specification. All of the aircrew escape propulsion systems covered by this document and its associated detail specifications are used for military aircraft only and have no commercial applications.
