Abstract : An approximate method is devised to determine temperature distributions during the transient aerodynamic heating of thin-skinned, heat-conducting bodies. This permits evaluation of the streamwise conduction errors arising in the measurement of heat-transfer coefficients based on the skin-temperature history. The present method is valid for a large range of body shapes and thickness distributions, within the limitations of one-dimensional (streamwise) heat conduction, quasi-isothermal surface, constant adiabatic wall temperature, and negligible radiative heat transfer. Numerical computations were carried out for flat plates, wedges, and conical, hemispherical, and hemicylindrical shells. The results are presented in the form of nondimensional charts that permit a rapid evaluation of a 10percent error threshold in transient heat-transfer measurements. (Author)
