Abstract

The invention discloses a cross-medium aircraft based on a common rotor and a cycloidal propeller. The aircraft comprises an aircraft body, a horizontal support frame and a cross-medium propeller. Anend part of the horizontal support frame is connected with the cross-medium propeller through a propeller tilting device, and the propeller tilting device is used for driving the cross-medium propeller to rotate in a vertical plane around an axis of the horizontal support frame; and the cross-medium propeller is provided with a plurality of blades evenly distributed around the axis of the cross-medium propeller, and the cross-medium propeller is connected with the roots of the blades through a blade turnover device. According to a deformation propeller considering performance characteristics of an aerial fluid and a underwater fluid, one set of propeller can be used for achieving omnidirectional maneuvering navigation and fixed-point hovering in the air and under the water, and a underwater slamming force and a storage space are reduced through composite deformation.

Description

technical field [0001] The invention relates to the technical field of water-air amphibious vehicles, in particular to a medium-crossing vehicle based on common rotors and cycloid propellers. Background technique [0002] A trans-media vehicle is a vehicle capable of flying in the air and submerging underwater. In the military field, it can complete tasks such as aerial reconnaissance, underwater detection, and penetration attacks, and can undertake different mission loads. In 2013, the U.S. Navy successfully launched a submarine-launched UAV named "XFC", which can carry photoelectric / infrared payloads and provide a new way of reconnaissance and detection for submarines. However, the "XFC" UAV itself has no power underwater, and it needs to be transported to the sea surface with the help of a carrier before it can be launched into the air. After the mission is over, it can only land on the sea surface and be recovered by the submarine. In the civilian field, in addition to ...
