Abstract
The use of a propeller is an option for powered flight on Mars. Powered flight in the Martian atmosphere is quite peculiar in that the propeller operates with low speed under low Reynolds number conditions. The improvement of the performance of the propeller for Martian flight is investigated, focusing on the blade solidity. First using the blade element momentum theory, the effect of the increase in solidity is investigated. Then, in order to verify this solidity effect experimentally, wind tunnel tests are carried out. Two propellers with different solidity are specially designed and tested. Through the measurement of thrust and torque, the effect of the solidity is discussed in terms of efficiency.
