ABSTRACT:
The present invention provides methods for integrating structural members inside the body of a propulsion vehicle with tankage used to store fluid propellant and the like. Propulsion vehicles may be made lighter, more compact, cheaper, and easier to manufacture by using pressurized membranes of the tankage to accomplish other structural purposes. More specifically, tanks may be integrated with thrust structures to transfer thrust loads from the engine to the main body of the vehicle. Alternatively, the tanks may be integrated with the vehicle engine. One tank may be integrated with one or more other tanks to form a single pressure vessel with multiple interior chambers. Methods of manufacturing a metallic integrated tank assembly include weld fabrication, machining, spinning, hydroforming, casting, forging, plating, metal deposition, or some combination thereof. Methods of manufacturing a composite integrated tank assembly include filament winding, fiber placement, hand-lay-up, or some combination. The methods listed above may be combined with other steps and tooling to create many different embodiments of the invention.
