This eliminates the need for a stout tool which reduces the overall process cost. In the self-reacting friction stir welding technique, two opposing shoulders are employed on the crown and root side of the weld joint with the forge force acting against the crown shoulder portion of the weld pin tool by the root shoulder. The high weld forge force is directed against an anvil and a stout tool structure. The plasticized material is welded through the application of a high weld forge force through the weld pin tool. The process uses a rotating weld pin that plasticizes material through friction heating. These components are joined by self-reacting friction stir welding which produces superior bonds and allows for the joining of Al-Li alloys that can not be welded using traditional techniques.įriction stir welding (FSW) is an innovative process that delivers high quality and high strength welds in aluminum alloys. The crew module’s core structure, the pressure vessel, consists of a number of components – an aft bulkhead and aft bulkhead cap, the crew module barrel, the forward cone, the forward bulkhead and crew module tunnel that would interface with a docked spacecraft. The pressure vessel and structural elements of the Orion spacecraft use olive-green aluminum-lithium alloy, the same was used for the Super Lightweight External Tank of the Space shuttle used for the majority of missions since 1998.

Overall, the Crew Module (CM) will have a maximum diameter of 5.02 meters standing 3.3 meters tall with a launch mass around 8,900 Kilograms, offering an internal volume of 19.56 cubic meters, 8.95m³ of which will be habitable volume that can be accessed by the crew. In its exterior design, the Orion Crew Module closely resembles the appearance of the Apollo Command Module, also using the 57.5-degree frustum shape. Orion was born as part of the Constellation Program as the Crew Exploration Vehicle and lived on through the cancelation of that program, continuing under the MPCV designation as development proceeded toward initial test flights before operational crewed missions using the Space Launch System in the next decade. Notably, Rocket Lab’s Photon will deploy the final satellite to an orbit of 450km, following the deployment of the other satellites at a 550km circular orbit.The Orion Multipurpose Crew Vehicle (MPCV) is a NASA spacecraft designed to take a crew of up to six Astronauts to destinations beyond Low Earth Orbit including the Moon, Mars and Asteroids.
