Problems solved by technology

When the trans-medium aircraft enters the water, the folding deformation of the air-use propeller is generally used to reduce the resistance of underwater sneaking. Although this method can reduce the sneak resistance to a certain extent, the air-use propeller is still outside the nose of the trans-medium aircraft. There is still interaction with the surrounding water flow, which still has a certain impact on the underwater diving of the aircraft, and this method will reduce the sealing effect of the aircraft underwater

Abstract

A propeller retractable integrated cross-media aircraft power system belongs to the technical field of cross-media aircraft. In the present invention, the nose telescopic mechanism is connected to the electromagnetic clutch I on the left side of the power mechanism through a connecting shaft; It is fixedly connected with the aircraft shell, and its left side forms a sliding connection with the secondary transmission rod in the nose telescopic mechanism through a sliding sleeve II; the power mechanism is connected with the aircraft shell through a dual-shaft stepping motor, and its right side is connected by an electromagnetic clutch II. It is connected with the propeller transmission mechanism for water use. The invention can be used for the design of the power system of the cross-medium aircraft. On the premise that the air-use propeller can be retracted, the air-use propeller and the water-use propeller can share a stepping motor, and the integrated design of the power system is completed. The medium aircraft has a good shape and tightness under water, and makes the trans-medium aircraft lighter and lower energy consumption.

Description

technical field [0001] The invention belongs to the technical field of cross-medium aircraft, and in particular relates to a propeller retractable and integrated cross-medium aircraft power system. Background technique [0002] The cross-media aircraft is a new concept sports platform designed by multi-disciplinary integration of aircraft and underwater vehicles. It is a new multi-functional integrated equipment that can fly in the air and dive underwater. The working mode of the aircraft can be divided into air flight mode, water entry mode, underwater sneaking mode and water exit mode, which can be switched among various working modes according to mission requirements. Cross-media unmanned aerial vehicles can be matched with submarines, surface ships and other equipment to perform tasks such as intelligence collection, reconnaissance and surveillance, communication relay, and electronic countermeasures across the sea and air. [0003] Due to the significant difference bet...
