Abstract

The utility model provides an ornithopter that can solve current ornithopter and bear a burden and flight time of endurance problem in flight. Its principle for the flapping wing airfoil after down motion produces lift and the thrust of ging forward, the reduction resistance of the in -process maximize that goes upward at the airfoil removes the unnecessary energy and economizes and consume. The ventilative structure of single face is made for the airfoil to the specific practice, power before the airfoil does not pass through the air and produces lift that the resistance becomes ornithopter and advance under the circumstances that the airfoil was fluttered downwards, and at the in -process airfoil of the airfoil upward movement resistance for ventilative state reduction air, the lift that does not hinder ornithopter reduces the energy consumption promptly.

Description

Flapping-wing aircraft

Technical field

The utility model relate to a kind of with the wing flapping-wing aircraft fluttered and circle in the air in atmosphere for lift, especially raise up in flapping wing During effectively reduce resistance, increase the flapping-wing aircraft of flapping wing operating efficiency.

Background technology

At present, known flapping-wing aircraft is not also highly developed in terms of design of Simulation, especially in aerofoil design not from Fundamentally solve aerofoil descending produce power after raise up the resistance of generation.Birds wing-type design has slightly been in progress, but The flapping-wing aircraft of design nor heavy burden, the energy saves consumption, and to be directed at greatly cruising time also very short, does not have practical value.In the flat wing such as butterfly Also do not start to walk on the wing-type design of shape insects.

Content of the invention

In order to solve the problems, such as existing flapping-wing aircraft in flight heavy burden and flight cruising time, the utility model is in the wing of flapping-wing aircraft Propose a kind of new solution in shape design, allow aerofoil after downward movement produces lift and forward thrust, up in aerofoil During maximized minimizing resistance, remove the unnecessary energy and save consumption.

The utility model solves its technical problem and be employed technical scheme comprise that：Aerofoil is made single-sided ventilating structure, In the case that aerofoil is fluttered downwards, aerofoil air proof produces the power before resistance is changed into the lift of flapping-wing aircraft and enters, aerofoil to During upper motion, aerofoil is the resistance that ventilative state reduces air, does not hinder the lift of flapping-wing aircraft to reduce energy consumption.Specifically Way is divided into two kinds：The first is to make many hollow on the skeleton of flapping wing, then becomes in each hollow place aerofoil Band plays movable wing or the aerofoil with elastic hinge composition that material is made certainly, in air pressure during flapping wing moves downward Power and the hollow place being tightly pressed against flapping wing skeleton from bullet material or elastic hinge collective effect lower aerofoil make flapping wing aerofoil form one The descending resistance of individual airfast overall increase is thus produce lift and onward impulse.During flapping wing moves upwards, empty Gas makes to be close to opening downwards and formed from missile wing face or the aerofoil with elastic hinge of skeleton through hollow skeleton under air pressure Hollow minimizing air drag.Second is the feather aerofoil profile of imitative birds, and equipped with many pair skeletons on main framing, secondary skeleton is loaded onto Imitative penniform band plays imitative featheriness aerofoil or the imitative featheriness aerofoil with elastic hinge composition that material is made certainly.Flapping wing to It is tightly pressed against flapping wing pair skeleton in air pressure with from bullet material or elastic hinge collective effect lower aerofoil during lower motion Hollow place make flapping wing aerofoil form one airfast overall to increase descending resistance thus producing lift and onward impulse.? During flapping wing moves upwards, air permeable pair skeleton makes to be close to cutting with scissors from missile wing face or band elasticity of skeleton under air pressure The aerofoil of chain opens downwards the hollow minimizing air drag of formation.

The invention has the beneficial effects as follows, can be dynamic before the descending acting of flapping wing in flapping-wing aircraft running produces lift and enters Maximize during flapping wing is up after the completion of power action and reduce resistance, remove the unnecessary energy and save consumption.Solve existing flapping wing Machine bears a heavy burden and flight cruising time problem in flight.
