Abstract
Abstract The invention provides a variable length mission configurable module that can be readily reconfigured to meet the specific pressurized space and payload requirements for a wide variety of Earth orbit missions. The module system includes a plurality of truncated body portions, a substantially flat forward bulkhead, and a substantially flat aft bulkhead. The plurality of truncated body portions and bulkheads are coupled together, wherein the forward bulkhead is located at a front end of a line of coupled truncated body portions and the aft bulkhead is located at an aft end of the coupled truncated body portions. The number of truncated body portions employed can be readily varied to adjust the overall length, pressurized volume and payload capabilities of the module system to specific mission requirements.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
A variable length mission configurable module that is pressurized for spaceflight, said module comprising: a first truncated body portion and a second truncated body portion, each including a curved wall and a flat top panel attached to an open end of the curved wall; a substantially flat forward bulkhead and a substantially flat aft bulkhead; and coupling means for coupling the forward bulkhead to a forward end of the first truncated body portion, an aft end of the first truncated body portion to a forward end of the second truncated body portion, and an aft end of the second truncated body portion to the aft bulkhead to form a combined module; wherein a pressurization force is applied to the flat top panel of the first truncated body portion and the flat top panel of the second truncated body portion, the flat forward bulkhead and the flat aft bulkhead when the combined module is pressurized for spaceflight; and wherein the coupling means includes means for maintaining a pressure profile for the combined module, when the pressurization force is applied, that is substantially similar to a pressure profile of a conventional single module.
Claim 2
Dependent Claim
191 words
A variable length mission configurable module that is pressurized for spaceflight, said module comprising: a first truncated body portion and a second truncated body portion, each including a curved wall and a flat top panel attached to an open end of the curved wall; a substantially flat forward bulkhead and a substantially flat aft bulkhead; and coupling means for coupling the forward bulkhead to a forward end of the first truncated body portion, an aft end of the first truncated body portion to a forward end of the second truncated body portion, and an aft end of the second truncated body portion to the aft bulkhead to form a combined module; wherein a pressurization force is applied to the flat top panel of the first truncated body portion and the flat top panel of the second truncated body portion, the flat forward bulkhead and the flat aft bulkhead when the combined module is pressurized for spaceflight; and wherein the coupling means includes means for maintaining a pressure profile for the combined module, when the pressurization force is applied, that is substantially similar to a pressure profile of a conventional single module.
Claim 3
Dependent Claim
34 words
A variable length mission configurable module as claimed in claim 1, wherein the coupling means includes a forward D-ring and an aft D-ring located on each of the first and second truncated body portions.
Claim 4
Dependent Claim
49 words
A variable length mission configurable module as claimed in claim 1, further comprising a third truncated body portion having a forward end that is coupled to the aft end of the second body portion and an aft end that is coupled to the aft bulkhead by the coupling means.
