Title:
ELECTRICALLY-DRIVEN IMPELLER TYPE FLOATING DEVICE
Document Type and Number:
Japanese Patent JP2023013897
Kind Code:
A
Abstract:
To solve such a problem that since a propeller exposes in a conventional rotary wing type device (helicopter, drone and so on) and the conventional device has obtained buoyance (lift) by moving air above the impeller downward, rains or snows hit the impeller during rain fall or snow fall, it was difficult to operate the device, and the device could not been used in bad weather.SOLUTION: In order to solve a conventional problem, provided is a device with a structure and a principle for obtaining buoyance (lift) that are different from a conventional device. Since the device of the present invention obtains buoyance (lift) by air stream from an impeller below a flat plate, rains or snows do not directly hit the impeller during rain fall or snow fall. There is no hindrance to action of buoyance (lift), and therefore, the device can be used even in bad wether.SELECTED DRAWING: None
