An aircraft propeller drive system (100) for an aircraft is disclosed. The aircraft has a propeller driven by an intermittent combustion internal combustion engine via the propeller drive system (100). The propeller drive system (100) has a first non-circular gear (120) adapted to be operatively connected to and driven by the engine, a second non-circular gear (132) driven by the first non-circular gear (120), the first and second non-circular gears (120, 132) having a variable gear ratio, a flexible coupling assembly (170) driven by the second non-circular gear (132), and an output shaft (102) driven by the flexible coupling assembly (170). The output shaft (102) is adapted for being connected to the propeller. An aircraft having the propeller drive system (100) and a method for transmitting power from an intermittent combustion internal combustion engine to a propeller of an aircraft are also disclosed.
