Patent number: 8002219Abstract: An annular fairing having aerodynamic, thermal, structural and acoustic attributes couples a launch abort motor to a space vehicle having a payload of concern mounted on top of a rocket propulsion system. A first end of the annular fairing is fixedly attached to the launch abort motor while a second end of the annular fairing is attached in a releasable fashion to an aft region of the payload. The annular fairing increases in diameter between its first and second ends.Type: GrantFiled: November 16, 2007Date of Patent: August 23, 2011Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Charles J. Camarda, Stephen J. Scotti, Pieter G. Buning, Steven X. S. Bauer, Walter C. Engelund, David M. Schuster

Patent number: 7357606Abstract: Methods and tool for simultaneously forming a bore in a work piece and forming a series of threads in said bore. In an embodiment, the tool has a predetermined axial length, a proximal end, and a distal end, said tool comprising: a shank located at said proximal end; a pilot drill portion located at said distal end; and a mill portion intermediately disposed between said shank and said pilot drill portion. The mill portion is comprised of at least two drill-tap sections of predetermined axial lengths and at least one transition section of predetermined axial length, wherein each of said at least one transition section is sandwiched between a distinct set of two of said at least two drill-tap sections.Type: GrantFiled: February 3, 2006Date of Patent: April 15, 2008Assignee: United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Donald R. Pettit, Ronald K. Penner, Larry D. Franklin, Charles J. Camarda

Patent number: 5720339Abstract: A thermal protection system containing several innovative features has been developed with heat pipes embedded in a composite material. The techniques used in the fabrication of the heat pipes permit a smaller radius and a higher use temperature heat pipe than could be manufactured under pervious techniques. The techniques used to embed the heat pipes in a refractory composite material yield a light weight leading edge that is able to tolerate the thermal stresses generated by the difference in thermal expansion between the heat pipes and the composite material. The heat pipes for the leading edge have a "J-shape", and are placed so that the long leg of the heat pipe alternates between the upper and lower surfaces. A coating is placed on the heat pipes that protects the heat pipe from oxidation and reaction with the components of the composite material.Type: GrantFiled: March 27, 1995Date of Patent: February 24, 1998Inventors: David E. Glass, Charles J. Camarda, Michael A. Merrigan

Patent number: 5598632Abstract: Flat or curved micro heat pipe panels are fabricated by arranging essentially parallel filaments in the shape of the desired panel. The configuration of the filaments corresponds to the desired configuration of the tubes that will constitute the heat pipes. A thermally conductive material is then deposited on and around the filaments to fill in the desired shape of the panel. The filaments are then removed, leaving tubular passageways of the desired configuration and surface texture in the material. The tubes are then filled with a working fluid and sealed. Composite micro heat pipe laminates are formed by layering individual micro heat pipe panels and bonding them to each other to form a single structure. The layering sequence of the micro heat pipe panels can be tailored to transport heat preferentially in specific directions as desired for a particular application.Type: GrantFiled: October 6, 1994Date of Patent: February 4, 1997Assignees: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration, Texas A&MInventors: Charles J. Camarda, George P. Peterson, Donald R. Rummler

Patent number: 5238056Abstract: Various heat exchange apparatuses are described in which an oscillating flow of primary coolant is used to dissipate an incident heat flux. The oscillating flow may be imparted by a reciprocating piston, a double action twin reciprocating piston, fluidic oscillators or electromagnetic pumps. The oscillating fluid flows through at least one conduit in either an open loop or a closed loop. A secondary flow of coolant may be used to flow over the outer walls of at least one conduit to remove heat transferred from the primary coolant to the walls of the conduit.Type: GrantFiled: February 24, 1992Date of Patent: August 24, 1993Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Stephen J.

Patent number: 4838346Abstract: A reusable, durable heat pipe which is capable of operating at temperatures up to about 3000.degree. F. in an oxidizing environment and at temperatures above 3000.degree. F. in an inert or vacuum environment is produced by embedding a refractory metal pipe within a carbon-carbon composite structure. A reusable, durable heat pipe panel is made from an array of refractory-metal pipes spaced from each other, each refractory-metal pipe being embedded within a carbon-carbon composite structure. The reusable, durable, heat-pipe panel is employed to fabricate a hypersonic vehicle leading edge and nose cap.Type: GrantFiled: August 29, 1988Date of Patent: June 13, 1989Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Charles J.

Patent number: 4485670Abstract: The basic heat pipe principle is employed to provide a self-contained passively cooled probe that may be placed into a high temperature environment. The probe consists of an evaporator region 13 of a heat pipe 10 and a sensing instrument 17. Heat is absorbed as the working fluid 22 evaporates in the probe. The vapor is transported to the vapor space 14 of the condenser region 15. Heat is dissipated from the condenser region and fins 20 causing condensation of the working fluid, which returns to the probe by gravity and the capillary action of the wick 18. Working fluid, wick and condenser configurations and structure materials can be selected to maintain the probe within an acceptable temperature range.Type: GrantFiled: February 13, 1981Date of Patent: December 4, 1984Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Charles J.
