Abstract

The invention provides a lift force device and belongs to the technical field of aviation. The lift force device comprises a fixing frame, an engine, a main shaft, a large gear, a rotary arm, a firstsmall chain wheel, a second small chain wheel, a first large chain wheel, a second large chain wheel, a first chain, a second chain, a first traction shaft, a second traction shaft, a first fixing clamp, a second fixing clamp, a first blade and a second blade. The middle portion of the rotary arm is fixed to the main shaft. The engine drives the rotary arm to rotate, the ceaselessly-rotating rotary arm drives the first blade and the second blade to conduct flapping actions by turns at a certain inclination angle, wherein the first blade and the second blade are kept perpendicular to each otherall the time. When the blades conduct flapping motion, a relative high pressure region can be formed below the blades, a relative low pressure region can be formed above the blades, and upward lift force is generated on the blades. The lift force device is high in efficiency and can continuously generate lift force; and the lift force device is installed on an air vehicle, the air vehicle can take off vertically, and the lift force device can be used for exploration or scientific research.

Description

technical field [0001] A lift device belongs to the technical field of aviation, and in particular relates to a lift device. Background technique [0002] At present, the flapping-wing aircraft has not yet reached the real practical stage, mainly because the traditional flapping-wing method is ineffective, which is not conducive to lift-off; the traditional flapping-wing aircraft is difficult to lift vertically. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of existing orthopter, invents a kind of device that can produce lift. [0004] A lifting device, including a fixed frame, an engine, a main shaft, a large gear, a rotating arm, a first small sprocket, a second small sprocket, a first large sprocket, a second large sprocket, a first chain, and a second chain , the first traction shaft, the second traction shaft, the first fixing clip, the second fixing clip, the first blade and the second blade. T...
