Fast-response, thin-skinned calorimeters provide a simple, rapid means of obtaining heat flux profiles of arc jet flows. A probe-sweeping technique is used to permit repeated radial profile measurements of heat flux during a single test run. It is shown that this technique is well suited for use in high heat flux environments when simplicity of calorimeter construction and data analysis is required. Such fast-response calorimeters also have application for catalytic surface measurements in nonequilibrium flows where time-dependent surface contamination is experienced. Experimental heat flux data from thin-skinned calorimeters used in arc jet flows are presented.
