Title:
ELECTRIC PROPULSION DEVICE FOR TRANSPORT
Document Type and Number:
Japanese Patent JP2022173007
Kind Code:
A
Abstract:
To solve the problem (1) that an impeller of a propeller of a conventional propulsion device of an airplane is installed in a horizontal direction with respect to a flying direction of the airplane, so that a phenomenon of bird strike in which a bird strikes the impeller during takeoff and landing occurs, which poses a problem for flying, and to solve the problem (2) that an impeller of a screw of a conventional propulsion device of a ship is exposed out of the ship, so that the impeller contacts underwater floating matters and therefore gets broken and gets tangled with seaweeds, which poses a problem for navigation.SOLUTION: In order to solve the problem (1) of an airplane, an impeller of a propulsion device is installed on a side surface of an outer shape (an outer surface) of a cone-shaped device to make the propulsion device have a structure in which bird-strike hardly occurs. In order to solve the problem (2) of a ship, an impeller is configured to be assembled into an outer shape (an outer surface) of a cone-shaped device to make a propulsion device have a structure in which the impeller hardly contacts underwater floating matters and hardly gets tangled with seaweeds.SELECTED DRAWING: None
