A high-efficiency multi-bladed propeller propulsion system for an airship

Abstract

The invention belongs to the technical field of airship propelling, and particularly relates to a high-efficiency multi-blade propeller propelling system for an airship. The system comprises a circular truss, a bearing, a plurality of blades and a motor. The circular truss is a concentrically circular frame with an inner layer and an outer layer, and has a trapezoidal section, and the inner side of the circular truss is an inclined side. The bearing comprises an inner ring, a plurality of rolling rotors and an outer ring, wherein the inner ring is fixedly connected with the outside of the circular truss, and the inner ring and the outside of the circular truss are distributed into a concentric circle; and a plurality of round holes are uniformly reserved in the outer surface of the outer ring, and are perpendicularly connected with the blades respectively to form a propeller. The motor is arranged on the circular truss, and is connected with a certain rolling rotor of the bearing. According to the system, the rolling rotors of the bearing of the propeller can be driven by the motor to rotate to enable the outer ring of the bearing to rotate and further enable the blades of the propeller to concentrically circularly rotate around an airship mounting section by taking a point of intersection of the airship mounting section and a longitudinal axis as a circle center, so that the airship can better fly in fixed point and controllable ways.

Description

technical field [0001] The invention belongs to the technical field of airship propulsion, and in particular relates to a high-efficiency multi-bladed propeller propulsion system for an airship. Background technique [0002] The airship is a kind of aerostat that relies on aerostatic buoyancy and can be maneuvered to fly. It has good maneuverability and maneuverability. Compared with other aircraft, it can achieve slow speed with relatively low power consumption The unique advantages of flying and fixed-point hovering have broad application prospects. [0003] In order to achieve fixed-point and controllable flight, the airship is required to have an efficient and reliable propulsion system. The choice of the layout of the propeller plays a vital role in improving the efficiency of the propeller itself and reducing the overall drag of the airship. The airship propeller in the existing traditional technology, its arrangement is nothing more than hull front end, hull tail en...

AI Technical Summary

Problems solved by technology

The propellers located at the front end of the hull or at the head and tail of the cabin will increase the resistance of the hull; the propellers located at the sides of the hull or cabin have limited contribution to reducing the resistance of the airship; However, it will increase the pressure differential resistance when the airship surface is normally attached to the flow. In addition, for larger airships, the rear of the hull forms a huge blunt body relative to the propeller. The application of this method also has limitations.
