[0002] Shaft drive, gear shift, propeller Summary of the Invention

[0003] The main engine (motor or gasoline engine or diesel engine) drives a main shaft to drive multiple transmission shafts. Each transmission shaft is connected to a speed change gearbox, and the gearbox is connected to a propeller to provide lift and thrust (forward, backward, left turn, right turn). The lift propeller can be retracted and extended through a hydraulic push rod or an electric push rod. Except for the power, transmission, and some structural parts, the fuselage is made of lightweight synthetic materials.

Claims

1. The main engine (electric motor or gasoline engine or diesel engine) drives a main shaft to drive multiple transmission shafts. Each transmission shaft is connected to a speed change gear box, and the gear box is connected to the propeller to provide lift and thrust (forward, backward, left turn, right turn).

2. The lift propeller can be retracted and extended by a hydraulic push rod or an electric push rod.
