Abstract
A store ejector is adapted for in-flight adjustment of the pitch attitude imparted to a store by a pair of ejector pistons. The pitch attitude of the store is adjustable to correspond to a flight condition of the aircraft at time of store release. The aircraft has a flight computer that provides store release pitch data corresponding to the aircraft flight conditions. The store ejector includes an orificing assembly that varies the flow of pressurized gas to the ejector pistons by translating a mandrel within a bore formed in the orificing assembly. Orifices within the bore are adjusted to apportion the flow of pressurized gas to the ejector pistons in accordance with an optimum orifice setting corresponding to the desired pitch attitude of the store for the given flight condition.
