Abstract
Abstract Spacecraft structures which are suitable for mounting within the bay of a space shuttle. Each structure comprises a plurality of modules, each module in the form of a truss network, these networks being secured to one another. Electronic payloads, thrusters, fuel tanks, solar arrays and other equipment are attached to the trusses. The end modules of each spacecraft structure include adjustable trunnions to releasably secure the spacecraft structure to the shuttle. A module may include a keel for releasably securing it (and the spacecraft structure of which it is a part) to the shuttle. Each spacecraft structure may be individually designed. For example, the number of expansion modules secured between two end modules of a structure may be varied as required by the load carrying capacity desired of a spacecraft structure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
188 words
A structure adapted to be stored in a launch vehicle, said structure supporting components which together with the structure form a spacecraft, the spacecraft to be launched from the launch vehicle when the latter is in space, said structure comprising: a first module comprising a first support body having a given longitudinal extent including means adapted to receive said components, said body including a first pair of trunnion members extending in opposite directions from said body, said trunnion members being adapted to be received in respective trunnion receiving means in said launch vehicle, said body including first mounting means for securing another body to said first support body, and a substantially planar keel structure means of a thickness much less than said longitudinal extent of said first support body and including second mounting means secured to and mating with said first mounting means and including a keel member adapted to engage said receiving means on said launch vehicle, said keel member extending in a direction normal to the direction of said trunnion members, said second mounting means being adapted to receive third mounting means from said another body.
Claim 2
Dependent Claim
188 words
A structure adapted to be stored in a launch vehicle, said structure supporting components which together with the structure form a spacecraft, the spacecraft to be launched from the launch vehicle when the latter is in space, said structure comprising: a first module comprising a first support body having a given longitudinal extent including means adapted to receive said components, said body including a first pair of trunnion members extending in opposite directions from said body, said trunnion members being adapted to be received in respective trunnion receiving means in said launch vehicle, said body including first mounting means for securing another body to said first support body, and a substantially planar keel structure means of a thickness much less than said longitudinal extent of said first support body and including second mounting means secured to and mating with said first mounting means and including a keel member adapted to engage said receiving means on said launch vehicle, said keel member extending in a direction normal to the direction of said trunnion members, said second mounting means being adapted to receive third mounting means from said another body.
Claim 3
Dependent Claim
47 words
The structure of claim 1 further including cradle structure means including a pair of trunnion members extending in said opposite directions adapted to be received in said launch vehicle, and keel locking means on said cradle structure means for receiving and releaseably securing said keel member thereto.
Claim 4
Dependent Claim
70 words
The structure of claim 1 wherein said another body includes a second module comprising a second support body including means adapted to receive said components, a second pair of trunnion members extending in like opposite directions as the trunnion members of the first module, and adapted to be received in said trunnion receiving means, said second body including said third mounting means mating with said first and second mounting means.
Claim 5
Dependent Claim
21 words
The structure of claim 3 further including trunnion adjust means for individually aligning each said trunnion member to a reference alignment.
Claim 6
Dependent Claim
58 words
The structure of claim 3 further including at least one expansion module secured between said first and second modules and including fourth and fifth mounting means at opposite ends thereof, said fourth mounting means mating with and secured to said first and second mounting means, said fifth mounting means mating with and secured to said third mounting means.
Claim 7
Dependent Claim
28 words
The structure of claim 5 wherein the first, second and fifth mounting means include female connecting means and said third and fourth mounting means include male connecting means.
Claim 8
Dependent Claim
24 words
The structure of claim 6 wherein said modules and keel structure means are serially connected in a direction approximately normal to said opposite directions.
Claim 9
Dependent Claim
24 words
The structure of claim 1 wherein said module and keel structure means each comprise a plurality of beam elements connected in a truss network.
Claim 10
Dependent Claim
19 words
The structure of claim 1 wherein said module and keel structure means form a segment of a right cylinder.
Claim 11
Dependent Claim
17 words
The structure of claim 1 further including trunnion adjust means for individually aligning each said trunnion members.
Claim 12
Dependent Claim
177 words
A structure adapted to be stored in a launch vehicle, said structure supporting components which together with the structure form a spacecraft, the spacecraft to be launched from the launch vehicle when the latter is in space, said structure comprising: a first structural truss module including a support body having a given longitudinal extent and means for securing said components to said body, means for securing a pair of trunnion members to said body extending in opposite directions from said body, said trunnion members being adapted to be received in respective trunnion receiving means in said launch vehicle, said body including first mounting means for securing thereto another body substantially identical to said support body, and a substantially planar keel structure means of a thickness much less than said longitudinal extent of said support body and including second mounting means secured to and mating with said first mounting means and including a keel member for engaging keel receiving means on said launch vehicle, said first and second mounting means including fastening means spaced in an identical array.
Claim 13
Dependent Claim
177 words
A structure adapted to be stored in a launch vehicle, said structure supporting components which together with the structure form a spacecraft, the spacecraft to be launched from the launch vehicle when the latter is in space, said structure comprising: a first structural truss module including a support body having a given longitudinal extent and means for securing said components to said body, means for securing a pair of trunnion members to said body extending in opposite directions from said body, said trunnion members being adapted to be received in respective trunnion receiving means in said launch vehicle, said body including first mounting means for securing thereto another body substantially identical to said support body, and a substantially planar keel structure means of a thickness much less than said longitudinal extent of said support body and including second mounting means secured to and mating with said first mounting means and including a keel member for engaging keel receiving means on said launch vehicle, said first and second mounting means including fastening means spaced in an identical array.
