Claims

[Scope of utility model registration request]

An inner rotating shaft is inserted into the hollow outer rotating shaft via a bearing, and a counter-rotating shaft that transmits power coaxially while being reversed to each other, and a counter-rotating shaft that transmits power coaxially while being reversed to each other, and a power distribution means to which a distribution output end is connected and an engine is connected to an input end, and which distributes and transmits engine power to these rotating shafts;
provided coaxially and overlappingly along the axial direction on each of the outer rotating shaft and the inner rotating shaft of the counter-rotating shaft,
A propulsion device comprising a pair of propulsion devices configured with opposite pitches and at least one of which has a variable pitch mechanism.
