Plate blade thrusting unit for flying vehicle

Abstract

The invention relates to a plate blade propulsion unit for an aerial vehicle, which is provided with two same portions which are bilaterally symmetrical relatively to the longitudinal symmetrical plane of the aerial vehicle and respectively mounted on the upper surfaces of the left wing and the right wing of the aerial vehicle, and each portion is composed of a crank, a connecting bar, a connecting bar guide, a plate blade, an inner side fixing plate and an outer side fixing plate. Motor drive is transmitted to the crank by a reducer casing, one end of the connecting bar does circular motion under traction of the crank, the other end does closed curvilinear motion similar to the profile of 'human ears', the middle of the connecting bar slides reciprocally in the connecting bar guide, the plate blades do motion constantly and reciprocally 'flap and unfolding' similar to an insect on the upper surfaces of wings and between the inner side fixing plate and the outer side fixing plate under drive of the connecting bar, thereby Weis-Fogh effect is produced to propel a an aerial vehicle to fly. The plate blade propulsion unit for an aerial vehicle has simple structure, high efficiency and safety.

Description

technical field [0001] The invention relates to a flat plate blade thrust device for an aircraft, which belongs to the field of aviation technology. Background technique [0002] At present, the propulsion device of aircraft mainly has three forms: propeller, turbine and jet engine. The traditional propeller has several disadvantages. First, it produces twisted airflow, which has an adverse effect on the safety and efficiency of the aircraft. Second, it has a large windward area, which produces greater resistance to the aircraft. Third, it is a curved surface, which is difficult to manufacture. Big. Although other two kinds of thrusters have high efficiency, their structures are too complicated. Contents of the invention [0003] The purpose of the present invention is to provide a flat blade propulsion device for an aircraft, which is driven by the engine through a set of mechanisms to generate the Weis-Fogh effect under the joint action of the fixed flat and flat blade...
