THERE are reasons for believing that in certain states of working, the resultant aerodynamic force on a blade element of an airscrew is normal to a helicoidal surface. The object of the present inquiry was to see to what extent this is borne out by experimental results. It is found that between no-thrust and maximum efficiency, the hypothesis is confirmed by experimental results for a certain set of helicoidal airscrews. In the course of the inquiry, a method of evaluating the torque coefficient! over the same range, is indicated—the method giving good accuracy.
