Abstract

626,454. Aircraft propeller drives. UNITED AIRCRAFT CORPORATION. Jan. 4, 1946, No. 333. Convention date, Feb. 17, 1945. [Class 4] [Also in Group XXIV] Two engines 26, 28 in an aircraft are coupled through driving shafts 34, transmission means 30, 32, driven shafts 36 and bevel gears and shafting as shown, to two propellers 10, 12, so that either or both engines may be used to drive the propellers in either of two speed ratios. Each of the transmission means 30, 32 is controlled by hydraulic clutches operated by the pressure of a pump driven by both the corresponding driving shaft 34 and the driven shaft 36 or by whichever of these may be rotating, as described in Group XXIV, the distribution of the pressure supply from the pump being effected by a valve controlled by the pilot to provide two forward speed ratios and neutral.
