HIGH TEMPERATURE TEST METHODS,

Abstract

Heating, loading and test measurement equipment for use in high temperature structural tests was developed and improved, as follows: A vacuum type heat tension pad which will simultaneously load a skin surface up to 12.0 psi and heat it to 550 degrees F at rates of 20 degrees F/second. Several devices using infrared lamps for producing very high temperatures and high energy fluxes. Reflectors for high density infrared lamp banks include specular finished aluminum and stainless steel. Comparison tests on several deflection probes which would mechanically transmit deflections of hot specimens. Materials investigated to find a coating for increasing specimen absorption of infrared energy. Specimen cooling methods studied by expanding liquid carbon dioxide through nozzles adjacent to a test specimen. Arc-powered devices for producing high fluxes and temperatures. A plasma jet which will draw either A.C. or D.C. power from ignitron controllers. A plasma jet for heating a leading edge. The two most promising types of high temperature strain gages. (Author)
