Abstract
A handheld underwater aircraft includes a battery compartment () and propellers. There are at least two propellers, which are symmetrically distributed on both sides of the battery compartment (), and are connected to the battery compartment (). A special design with axes of the propellers being unparallel with an axis of the battery compartment () is adopted, and unparallel included angles make component forces generated by the various propellers in a direction of motion of a non-underwater aircraft offset each other, and enable the underwater aircraft to maintain balanced and forward-forward motion. The design with the axes of the propellers being unparallel with the axis of the battery compartment () leads to a little power loss, but avoids a larger power loss caused by the impact of water on the human body, thereby comprehensively improving the thrust of the underwater aircraft in use.
