LABORATORY TESTS OF PROPELLER BLADE PROFILE PRESSURE DISTRIBUTION UNDER ICE CONTACT. VOLUME I

A series of tests on propeller blade profile pressure distribution during ice interaction were performed in a small ice tank. The main parameters in the test matrix were the angle of attack and width of the cut ice. The interaction process was found to be cyclic. Ice was crushed and extruded cyclically when the blade proceeded. The cycles were associated with peaks in the load time histories. With normal angles of attack the majority of the pressures were acting on the back side of the blade and the face side received very small loads. The ice flaked and spalled away from the leading edge towards the free edge of ice before any real contact was developed at the face side. The resultant load was acting on the face side only when the angle of attack was large and when there was no contact at the back side. The load was concentrated in a very small area behind the leading edge. The absolute values of the pressures were not very high but they were clearly temperature dependant.
