Abstract

Abstract

The effect of the detector installing structure on the measured point temperature is analyzed using engineering aero-thermodynamics and heat conduction computation. To diminish the effect, a temperature detector installing structure is brought out according to the vehicle shell structure. The result shows that the installing structure has no effect on the measurement point temperature when the surface temperature is rising or heat is transmitting from the surface to the interior. However, the measurement temperature using the original installing structure is obviously lower than the predicted point temperature without the detector when heat is transmitting from the interior to the surface during the flight middle course. The temperature detector installing structure proposed in the paper can greatly reduce the structure effect on the measured point temperature:the maximum deviation of the temperature due to the presence of the detector is less than 0.5K.
