Gliding and propelling dual-mode underwater helicopter

Abstract

The invention discloses a gliding and propelling dual-mode underwater helicopter. The gliding and propelling dual-mode underwater helicopter comprises an upper shell and a lower shell, the mounting substrate is horizontally arranged between the upper shell and the lower shell; the mounting frame is vertically arranged in the middle of the mounting base plate in a penetrating mode, driving mechanisms are arranged at the top end and the bottom end of the mounting frame respectively, and output shafts of the driving mechanisms vertically penetrate the outer portion of the shell and are connected with fin plates; the buoyancy adjusting mechanism is mounted on the mounting base plate in an embedded manner and is locked and fixed through a locking piece; and the propeller propelling mechanism comprises two horizontal propellers which are symmetrically arranged and two vertical propellers which are symmetrically arranged. The underwater helicopter is high in maneuverability, good in stability, low in power consumption, long in endurance time and wide in operation range, the stability of the whole underwater helicopter can be improved by combining with the effect of the fins, yaw moment generated in the gliding process of the underwater helicopter is offset, and the underwater helicopter can glide in the fixed course.
