Abstract

11,785. Liwentaal, A. May 16. Screw propellers.-The blades of propellers are formed with a number of minor blades extending end-on, and decreasing in size and increasing in inclination from root to tip. Projections are provided and the blades have a common leading edge. The sections A<1>, A<2>, A3, A<4> of the blade shown i n Fig. 1 increase in inclination as the areas decrease, and the leading edge E is common to all. Between each section a projection is provided which extends from both faces. The Provisional Specification also states that the inclination may decrease at the same time as the size of the blades increases.
