Abstract

577,524. Propellers; helicopters. BOSSI, E. June 1, 1944, No. 10510. Convention date, June 4, 1943. [Class 4] An anti-torque propeller for a rotary wing aircraft rotatable about a horizontal shaft 5 laterally of and close to a side wall of the tail end of the fuselage, has air supplied to the sector covered by the fuselage from an outlet 11 in the fuselage. The air may be forced into the fuselage from the blades 3 of the rotary wing system. The air-inlet port 13 is adjustable by the pilot.
