The thermal effects of wing color for drones performing in the Martian atmosphere are investigated during the summer and winter seasons. The optimal wing color configuration is identified in each season. This study focuses on two useful consequences of the thermal effects of wing color: the skin friction drag reduction and the thermoelectric generation of power. According to its color, every side has a certain temperature affecting the local skin friction drag. Investigations of various configurations have shown that the thermal effect on the wing boundary layer is insignificant because of the low atmospheric pressure. However, the large temperature difference the top and the bottom of the wing has a great potential of thermoelectric power generation. The maximum temperature differences between the top and bottom surfaces for the summer and winter seasons are, respectively, 65 K and 30 K. The drag reduction and the power generation via thermoelectric generators both contribute to enhancing the endurance of drones. Future drone designs will benefit from the increased endurance through optimizing the wing color configuration. |
