One kind of solar thermal protective means Aerodynamic

The present invention discloses a solar wing aerodynamic heat shield means belonging spacecraft thermal control technology. Said pneumatic means from the bottom heat shield comprises a base film, a spacer layer, mask the surface, subsurface mask, which is fixed by sewing line; solar wing is provided with pin holes on the clamping point embedded guard aerothermal piece piercing hole. The present invention also discloses a method for thermal protection solar wing aerodynamic: pneumatic thermal protection device is mounted on the back surface of the solar wing, the reserved pin from the pin hole pneumatic means through the heat shield, mounting pad on the top of the pin to thermal protection means to prevent air from coming off the pin. Relative to a conventional solar wing of bare surface, the aerodynamic heat shield means employed in the present invention, a pneumatic deceleration, hot air can be isolated to some extent, that the solar wing temperature is maintained within the tolerable range.
