INVESTIGATION OF A MOVING BELT RADIATOR.

Abstract

The report covers the second quarter of a continuing research program on the feasibility of the moving belt radiator, a novel concept for the rejection of waste heat in space. The chief concerns of the program are materials compatibility, thermal conduction between surfaces, and antifriction bearing operation (all at high temperature in a hard vacuum), and the dynamic behavior of the belt, roller, and drum system under simulated in-flight conditions. During this report period, the materials compatibility and heat transfer investigations in the reciprocating-contact testers and the small-scale model were continued; and the bearing investigation was continued with the performance of seven tests of size 204 bearings. The fabrication of the pilot model for dynamic simulation of in-flight operation is nearing completion, and the design of the 1/5-scale dynamic model is in progress. (Author)
