Abstract

In order to study the impact of heat flux on missile body discharging by missile gas, the change of heat flux was measured by heat flux sensor. Using NiCr-Constantan foil thermocouple for temperature difference that formed by receiving the heat flux from sensitive element-Constantan foil based on the theory of heat conduction into heat flux signal. The relationship between heat flux density and output signal of heat flux was worked out with analysis on conduction process and a heat transfer model was daveloped based on nonlinearity of thermal conductivity relative to temperature that had been considered, program of heat transfer was compiled. Through comparing calculated value with measured value, the accuracy of the model was proved.

Key words： heat flux sensor; constantan foil; sensitive element; thermal conductivity; thermocouple; heat transfer model
