    摘要: A spacecraft propulsion module (16) that includes an outer cylindrical housing (20), an end wall (22) and a specialized internal structure (50) that is capable of supporting various spacecraft components (110, 112, 124), to provide different levels of spacecraft complexity for different missions. The internal structure (50) within the housing (20) includes a plurality of inner walls (52-58) defining an "eggcrate" structure. The plurality of inner walls (52-58) includes a first pair of walls (52, 54), extending in one direction and a second pair of walls (56, 58) extending in a substantially orthogonal direction to define a center compartment (76) surrounded by a plurality of perimeter compartments (60-74). The inner walls (52-58) and the outer housing (20) define support surfaces on which can be mounted different spacecraft components, such as propellant tanks (110), pressurant tanks (168), life support tanks (126), control, guidance, navigation and communication avionics (124), batteries (112), etc. depending on the particular spacecraft design. The outer surface of the cylinder housing (20) and end wall (22) provide a significant amount of surface area for mounting engines (36) and thrusters (38) to give the module (16) free flying capability for both four and six degrees of freedom. The intersection of the inner walls (52-58) gives the spacecraft module (16) four inner mounting points (80-86) and the intersection of the inner walls (52-58) with the outer housing (20) gives the spacecraft eight outer mounting points (88-102). These mounting points (80-102) gives the spacecraft module versatility to attach different types of mounting adapters (42, 44, 46, 164) to connect other spacecraft modules to the propulsion module (16), such as crew modules, cargo modules, equipment modules, additional propulsion modules, etc.

    摘要: A method of launching a two stage vehicle (20) and a trajectory for use with a two stage vehicle (20) which allows recovery of both stages at the launch site. This is accomplished by launching the first stage (24) completely vertically so that on burnout the first stage (24) is positioned directly above the recovery site. In order to get maximum benefit from launching the stage vertically gravitational losses are minimized by a first stage thrust to weight ratio of 1.6. The high thrust to weight ratio results in burnout at approximately 100,000 feet altitude within the atmosphere. Therefore the vehicle employs engines (27) which produce at altitude approximately 15 percent of the sea level thrust of the first stage and consume the last 5 percent of propellant over a time period of 40 seconds. Staging is accomplished at 200,000 feet altitude. The second stage (24) employs uprated RL-10 engines (25) and has a thrust to weight ratio of 1.45 and can achieve orbit with a velocity change of approximately 24,500 feet per second. The first stage (22) employs air breathing vertical lift engines (27) for recovery. The second stage (24) utilizes a parawing (55).

    摘要: A propellant immobilizing system and method in which propellant motion in the propellant storage tanks (22) is reduced or eliminated during velocity change maneuvers to reduce disturbance torques acting upon the spacecraft (10) and improving the spacecraft attitude pointing performance. The thrusters (14, 16, 18 or 20) are fired to produce a small impulse in the direction of the desired velocity change to begin motion of the propellant within the fuel tank in the opposite direction. After the fuel has moved within the tank to a location in which the propellant center of mass is aligned with the propellant tank (22) center of curvature in the direction of the desired velocity change, thrusters (14, 16, 18 or 20) are again fired to produce a force in the direction of the current velocity of the propellant center of mass to stop the propellant center of mass relative to the propellant tank (22). With the center mass of the propellant now aligned with the propellant tank center of curvature in the direction of the desired velocity change, the thrusters (14, 16, 18 or 20) are again fired to produce the desired velocity change with the propellant center of mass now being trapped in the propellant tank such that additional motion of the propellant is inhibited. After completion of the maneuver, the propellant gradually migrates back to its original position due to the influence of a propellant management device within the propellant tank.
