A transfer vehicle for use in a system for transferring payloads from an earth-launch vehicle in one space trajectory to another space trajectory. The system includes a space launch vehicle (FIG. 9) with primary propulsion and guidance systems, a transfer vehicle (FIG. 1) carrying a payload which is stowed in the cargo bay during earth-launch and insertion of the earth-launch vehicle into low-earth transfer trajectory. An engine module (FIG. 3) carrie on-board mission equipment, rocket engine, related fuel supply, guidance equipment, attitude control equipment and electrical power supply equipment (FIGS. 11-20). A grapple system on the earth-launch vehicle (FIG. 9) deploys the transfer vehicle and cargo and restows it for on-orbit repair/modification for earth-return. The transfer vehicle may be multi-staged (FIG. 21) and may be provided with multiple engines (FIG. 23).

In a system for transferring a payload from an earth-launch vehicle in one space trajectory to another trajectory, said system including an earth-launch vehicle, having fuselage means including a cargo bay defining a mass-distribution envelope therein, and primary propulsion and guidance systems for launching said earth-launching vehicle from earth for injection into a low-earth transfer trajectory; a transfer vehicle carrying said payload, stowed in said cargo bay during earth-launch and insertion of said earth-launch vehicle into said low-earth transfer trajectory; and means for un-stowing said transfer vehicle/payload combination from said cargo bay preparatory to operation of said transfer vehicle to transfer said payload to said other trajectory; the improved transfer vehicle characterized in that the improved transfer vehicle has multiple stages, including, in combination: (A) at least two rocket-powered propulsion stages arranged and releasably secured together in tandem relationship, each said stage including (1) a support frame, (2) at least one rocket engine mounted in said frame; and (3) the fuel supply for said engine; (B) means for releasably mounting a payload on the upper end of said tandem propulsion stages; (C) avionics and post-deployment support systems for said vehicle carried in the support frame of the upper propulsion stage; and (D) trunnion-cheek means formed integrally with the support frame of at least one of said propulsion stages and said fuselage means to directly, releasably support and position said vehicle and attached payload within the dimensional and mass-distribution envelopes of said cargo bay.
