Structural testing at high temperature

Abstract

This paper describes the equipment and procedures used in testing a large multicell box beam under various combinations of applied loading and transient heating. Data are presented on the performance of radiant-heat lamps when enclosed by aluminum reflectors and powered by automobile-type batteries. In addition, solutions are given to the following special problems introduced by simulating fuel conditions: (1) sealing the specimen without disturbing the normal paths for heat flow; (2) protecting strain gages and thermocouples from the simulated fuel.
