Abstract: The heat transfer of the manned spaceship’s re-entry module in the landing stage is analyzed. By analyzing various related heat transfer approaches, the heat transfer models are simplified, and the concept of the Composited Heat Transfer Coefficient is put forward. The formula for the composited heat transfer coefficient is derived, and its value is determined after measuring the air temperature within and outside the landed cabin in the laboratory environment. The obtained engineering data could be used for predicting the temperature inside the landed cabin during the long time waiting for rescue.
