Abstract
A power plant for propeller aircraft has two propulsion devices, each having a propeller, an engine for powering the propeller, and a gear transmission interposed between the engine and the propeller. The transmission has a power input shaft connected directly to the engine, and a power output shaft supporting the propeller and rotated with respect to the input shaft about a hinge axis perpendicular to the output shaft. The gear transmission also has a single gear fitted to the output shaft and having two opposed sets of teeth meshing with a pair of pinions. One of the pinions extends coaxially with the hinge axis, and is connected to the input shaft by a single pair of gears.
