Abstract

909,004. Screw propellers. AXMANN, K., AXMANN, A., and HAW, J., [trading as DEUTSCHE PROPELLERBAU-GES. HAW & CO.]. Nov. 13, 1958 [Nov. 18, 1957; Sept. 8, 1958], No. 36550/58. Class 114. A propeller blade has an internal tension, member to absorb the forces acting on the blade which is provided with vibration damping or lessening means integral with or rigidly connected thereto. In Fig. III the tension member is bifurcated, having arms 301, 302 to which are secured the vibration damping ribs 71. In Figs. IV and V the vibration damping means comprise hollow bases 32 formed on, and of tear drop shape in the plane of, the tension member 30. In Fig. XII the vibration dampers are formed as semi-spherical protrusions 310, 320 pressed out of the tension member 300. The space between the tension member and the aerofoil shell (600) may be filled with an aerated material having a high coefficient of friction (as at 500 in Fig. XII).
