Analysis of Propeller Efficiency Losses Associated with Heated-Air Thermal De-Icing

Abstract

An analysis is made of the loss of efficiency associated with a heated-air thermal de-icing propeller both with and without internal flow. For the available data, measured efficiency losses are compared with the calculated losses and the agreement is found to be within the experimental accuracy of the data. The method presented may be used with reasonable accuracy to determine the net change in propeller efficiency due to the combined effects of the nozzle and internal flow if the characteristics of the propeller without nozzles are known.
