Title:
HAND-HELD UNDERWATER AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2020/082441
Kind Code:
A1
Abstract:
Disclosed is a hand-held underwater aircraft, comprising a battery compartment (12) and propellers. A special design with the axis of the propellers being unparallel with the axis of the battery compartment is adopted, the unparallel included angles make the component forces generated by various propellers in the direction of motion of the non-underwater aircraft offset each other, and enable the underwater aircraft to maintain balanced and straight-forward motion. The design of unparallel axes of the propellers and the battery compartment (12) leads to a little power loss, but avoids larger power loss caused by the impact of water on the human body, thereby comprehensively improving the thrust of the underwater aircraft in use. The design of unparallel axes of the propellers and the battery compartment (12) leads to a little power loss, but avoids larger power loss caused by the impact of water on the human body, thereby comprehensively improving the thrust of the underwater aircraft in use. Moreover, the water does not strike on the user's face, thereby effectively preventing the user from inhaling water, making the user feel more comfortable and safer, and effectively improving the overall use experience.
