INVESTIGATION OF A MOVING BELT RADIATOR.

Abstract

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. The materials compatibility and heat transfer investigations in the reciprocating-contact testers were completed with the performance of a 1,000,000-cycle reverse flexure test between tinned molybdenum specimens; the small-cycle reverse fluxure test between tinned molybdenum specimens; the small-scale model investigation was completed with the running of a 100-hour duration continuous test between a molybdenum belt and tinned drums; the bearings investigation was completed with running of the last six tests of size 210 bearings; and the dynamic simulation of in-flight operation was continued with further pilot model testing and the initial checkout of the 1/5 scale model.
