Abstract:
A method of manufacturing a forging (110) for forming a split casing comprising the steps of creating a forging (110), for example, by a ring rolling process and then deforming the forging (110) by compressing it along a first axis (A) and/or extending it along a second axis (B).
Abstract:
A method and kit for retrofitting an inertia reel door onto the seat back of a preconstructed ejection seat is disclosed. The method includes removing existing rivets from the seat back exposing rivet holes. Alignment holes are then drilled into the seat back. An aperture is cut into the seat back along flanges of an upper support bracket and a drogue chute bracket. A doubler is aligned with the rivet holes and alignment holes in the seat back and then attached to the seat back. A track is attached to a wall of the aperture and an inertia reel is mounted to the track. An inertia reel door is attached to the doubler.
Abstract:
A method of assembling and installing a flip-up pitots system (10) in an ejection seat. A flip-up pitot mount (24) may be fastened to any existing recovery parachute container assembly (12). Mounting holes (26, 34) are created for the various parts that comprise the flip-up pitots system using the sub-parts as templates. The flip-up pitot system sub-parts are then easily installed on the recovery parachute container assembly irrespective of the make or model of the recovery parachute container assembly.
Abstract:
An apparatus for thickening a tube at its intermediate portion is disclosed. The apparatus includes a first support member, that is configured to support an outer surface of the tube. At least a portion of the first support member is defined with a profile corresponding to a profile of the intermediate portion of the tube to be thickened. The apparatus further includes a mandrel configured to support the inner surface of the tube, and a second support member which is configured to support an end of the mandrel. The apparatus includes a punch structured to abut an end of the tube between a free end of the mandrel and the first support member. The punch is configured to exert axial force onto the tube. Application of axial force by the punch plastically deforms the tube resulting in thickening of the tube at the intermediate portion.
Abstract:
A method for modifying the processing capabilities of a container. The method includes providing a container that defines a cavity and comprises a wall. The wall defines at least a portion of the cavity and has thermal energy transfer characteristics. At least one of the thermal energy transfer characteristics comprises a first value. Changing the first value of the one thermal energy transfer characteristic to a second value for at least a first portion of the wall, the second value being different from the first value..
Abstract:
A method of manufacturing a ball joint housing, comprising the steps of drawing, to reduce a diameter, the tip side of a cylindrical material (41) in pressurizing direction by extrusion by pressurizing it along the axial direction thereof so as to provide an intermediate formed body (46) having a cylindrical part (43), an inclined part (44) convergent continuously with the cylindrical part (43), and a small-diameter cylindrical part (45) coaxial with the cylindrical part (43), controlling the external and internal surfaces of the cylindrical part (43) of the intermediate formed body (46) and the external surface of the small diameter cylindrical part (45), pressurizing the cylindrical part (43) from the end part along the axial direction therefof so as to crush the inclined part (44), and forming the cylindrical part (43) on a body part (14), the inclined part (44) on a bottom part (17), and the small diameter cylindrical part (45) on a connecting part (23) so as to form a first housing (11), whereby a pressurizing force is reduced remarkably below that required when a solid cylindrical material is forged, formability can be increased, cutting is eliminated owing to forward extrusion, and forming can be performed with high accuracy.
Abstract:
A method of rear drive conversion of the M113 family of vehicles to provide a light, mobile and tactical hybrid vehicle. The method includes stripping an M113 to a base aluminum hull (10) and providing modified or newly fabricated parts (24, 25, 26, 28) to produce a converted rear drive vehicle (30). Using the rear drive conversion process, critical operations parameters such as volume under armor, mobility, air transportability and vehicle performance efficiency per unit weight are significantly increased.
