PADs include such devices as catapults, rocket catapults and rocket motors which are used in military aircrew escape systems. All catapults, rocket catapults and rocket motors currently in use are solid-propellant devices. In conjunction with various CADs and other life-support equipment, PADs power the ejection system utilized to eject aircrew members safely from disabled aircraft. Both CADs and PADs contain the energetic material along with a mechanical or electronic actuating component.
