INVESTIGATION OF A MOVING BELT RADIATOR.
Abstract
This report describes 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 were continued in the reciprocating-contact testers and the small-scale model; and the bearings investigation was continued with the performance of a 200-hour test of a size 204 bearing and the activation of the size 210 bearing test rig. The pilot model for dynamic simulation of in-flight operation was completed and testing initiated, the reduced gravity experiment was conducted to obtain belt shapes during elastic deployment, and the design of the 1/5-scale dynamic model was completed and fabrication begun.
