NASA NTRS1985

Heat transport across structural boundaries

A description of a program which uses heat-pipe principles in the design of prototype rotating thermal joints for the NASA centralized thermal control system, as well as of the first six months of work, during which the contract goals were met, is given. The design requirements include operating in a temperature range from 0 to 40 C, transferring 10 kilowatts with an overall temperature drop of 5 C, and rotating a total of 60,000 revolutions at 2 rpm with a 1700 inch pound moment loading. The predicted and required performance for the rotating joint are compared and the results are presented in a table. Consideration is also given to Phase II of the program.

NASA NTRS1985

High performance flexible heat pipes

A Phase I SBIR NASA program for developing and demonstrating high-performance flexible heat pipes for use in the thermal management of spacecraft is examined. The program combines several technologies such as flexible screen arteries and high-performance circumferential distribution wicks within an envelope which is flexible in the adiabatic heat transport zone. The first six months of work during which the Phase I contract goal were met, are described. Consideration is given to the heat-pipe performance requirements. A preliminary evaluation shows that the power requirement for Phase II of the program is 30.5 kilowatt meters at an operating temperature from 0 to 100 C.
