Abstract: A gas jet engine nozzle such as a turbine engine nozzle is provided for directing an axial flow in a downstream direction of exhaust gases to obtain thrust vectoring. The gas jet engine nozzle comprises an exhaust nozzle member for channeling the axial flow of the exhaust gases into a flow field, and a plug movably positioned substantially within the exhaust nozzle member and in the flow field for interacting with the gases to control the direction of flow of the gases. The plug has a substantially continuous surface including a diverging forebody portion and a monotonically converging afterbody portion. The afterbody portion is in the downstream direction relative to the forebody portion. A support structure is coupled to the plug for movably supporting the plug within the exhaust nozzle member and in the flow field. A hydraulic actuating system is operatively coupled to the plug for selectively controlling the position of the plug.

Abstract: An airship telescopic boom adapted for mounting on an airship for securing airship mooring lines when docking the airship. The boom may be used for the handling of a fuel line in the refueling of the airship, transferring of airship supplies and equipment, and similar applications. The boom reduces the requirement for a large ground crew and possible injury to related personnel.

Abstract: A method and a mold for fabricating an aerodynamic airframe structure or the like. The method using foam material introduced into the mold having split halves. The mold constructed for receiving a prefabricated stiffener skin. The mold acts as a backup restraint for the airframe structure or any other part being produced. The foam injected into the cavity adheres to the stiffener skin thereby forming an elastic foundation of continuous support for the stiffening element.

Abstract: An alignment device for adjusting the takeoff assist thrust vector of a rocket booster in a desired relationship to the center of gravity of an autonomous missile. The device provides for using "plumb bob type" hanging tool prior to installing the rocket booster on the missile.
