Abstract

Abstract A re-entry vehicle that includes three detachable modular components which anticipate total re-useability. Modularization of the composite re-entry vehicle offers great flexibility in re-arranging the various modules to suit a particular mission. The three module components include a crew module, principally serving as a crew cabin, and attached thereto is a modular heat shield or re-entry module which principally provides for thermal protection of the cabin module during re-entry. Propulsion for the cabin module to achieve a particular re-entry orbit is provided by a versatile service stage which becomes detached from the other two modules upon attainment of a desired re-entry trajectory. When used in conjunction with a Space Station, the versatile service stage may be propelled back to the Space Station for refueling and re-use.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 123 words
A method for providing a flexible modular re-entry vehicle operating with an Earth-orbiting Space Station, comprising the following steps: securing a crew module to the Space Station thereby providing access to the module; externally attaching an interchangeable thermal protection module to the crew module for protecting the crew module during re-entry to the Earth's atmosphere; externally attaching a replaceable propulsion module to the thermal protection module; releasing the three attached modules from the Space Station; operating the propulsion module thereby moving the vehicle from the Space Station; separating the propulsion module from the thermal protection module; establishing an Earth-bound trajectory for the remaining attached crew and thermal protection modules; and returning the propulsion module to the Space Station free of the crew module.
Claim 2
Independent Claim 123 words
A method for providing a flexible modular re-entry vehicle operating with an Earth-orbiting Space Station, comprising the following steps: securing a crew module to the Space Station thereby providing access to the module; externally attaching an interchangeable thermal protection module to the crew module for protecting the crew module during re-entry to the Earth's atmosphere; externally attaching a replaceable propulsion module to the thermal protection module; releasing the three attached modules from the Space Station; operating the propulsion module thereby moving the vehicle from the Space Station; separating the propulsion module from the thermal protection module; establishing an Earth-bound trajectory for the remaining attached crew and thermal protection modules; and returning the propulsion module to the Space Station free of the crew module.
Claim 3
Dependent Claim 18 words
The method set forth in claim 1 together with the step of refueling the propulsion module for re-use.
Claim 4
Dependent Claim 24 words
The method set forth in claim 1 wherein the thermal protection module chosen for use has a preselected geometry for achieving predetermined flight characteristics.
