Filed:

Apr 10, 2003

Appl. No.:

10/412132

Inventors:

Michael L. Hand - Huntington Beach CA
Edward E. Cook - Orange CA
Samuel S. Yao - Fountain Valley CA

Assignee:

The Boeing Company - Chicago IL

International Classification:

B64B 122

US Classification:

244158R

Abstract:

Methods and apparatus are provided for a tubular composite structure with particular application to the design and assembly of space vehicles. The apparatus, designated herein as an X-strut, comprises alternately crossing tow-placed layers of parallel strands of a composite material, to form top and bottom intersecting faces. Alternately crossing strand layers are built up from the bottom faces to form the side walls of the tubular composite structure. The top and bottom faces and the side walls are configured to form intersecting tubular members in an X-shape. The layers of strands run continuously through the intersecting tubular members to form an integral joint, without the need for adhesive bonding or mechanical fasteners.

International Classification:

F17C 3/08
F17C 7/02

US Classification:

62 451, 62 501

Abstract:

A cryogenic propellant storage tank system and method are disclosed that thermally couple LO2 and LCH4 tanks together by using either a single tank compartmentalized by a common tank wall or two separate tanks that are coupled together with one or more thermal couplers having high thermal conductivity. Cryogenic cooling equipment may be located only in the LO2 tank while the LCH4 is cooled by the LO2 tank interface. Embodiments of the invention may employ both LO2 and LCH4 liquid acquisition devices (LADs) for low-gravity use. In further embodiments, only the LO2 LADs may be integrated with thermal cooling equipment.

Abstract:

A ceramic matrix composite structure has a reinforced core for carrying loads. The core includes a web connected between the facesheets by edge bonded joints for transmitting compressive, tensile and shear loads. The edge bonded joints are laterally reinforced by bridging members bonded to the facesheets, on opposite sides of the webs The bridging members may comprise low density, high temperature rigid foam.

International Classification:

B05D 1/36

US Classification:

427258, 428632

Abstract:

An integrated composite structure with a graded coefficient of thermal expansion (CTE) is formed by selecting a plurality of layers of materials with a graded CTE and using build-up (bottom-up) fabrication approaches such as metal deposition or powder metallurgy to produce a CTE-graded layered composite preform, which is then consolidated and heat treated to create the CTE graded integrated composite billet or near net shape. The integrated composite billet or near net shape is then processed to produce a first surface for attachment of a first structural member having a first CTE and to produce a second surface of for attachment of a second structural member having a second CTE.
