<p>A power plant (1) for propeller aircraft has two propulsion devices (5, 6), each having a propeller (7), an engine (8) for powering the propeller (7), and a gear transmission (9) interposed between the engine (8) and the propeller (7). The transmission (9) has a power input shaft (10) connected directly to the engine (8), and a power output shaft (11) supporting the propeller (7) and rotated with respect to the input shaft (10) about a hinge axis (3) perpendicular to the output shaft (11). The gear transmission (9) also has a single gear (12) fitted to the output shaft (11) and having two opposed sets of teeth (13, 14) meshing with a pair of pinions (15, 16). One of the pinions (15, 16) extends coaxially with the hinge axis (3), and is connected to the input shaft (10) by a single pair of gears (21, 22). <IMAGE></p> |
