Abstract

The utility model discloses a purely-human-powered or power-assisted ornithopter, belonging to the technical field of ornithopters. According to the utility model, inner wing frameworks of wings are in a pair of zigzag cross structure made of an elastic material, downward wing flapping is realized by pushing a pulling rope downwards, and upward wing flapping is realized by the automatic return of the frameworks which are made of the elastic material. A low-power engine can be installed as an assistant power, thus contributing to gliding off on a flat ground, making up the disadvantages of human-powered wing flapping, and enhancing the flying climbing force and the gliding capacity. The utility model provides a personal ornithopter which is simple, efficient and practical, which is expected to become the most basic vehicle for human.

Description

Flapping wing aircraft a kind of pure manpower or power-assisted

Technical field

Flapping wing aircraft a kind of pure manpower or power-assisted belongs to the flapping wing aircraft technical field.

Background technology

There is not substantial breakthrough in the flapping wing aircraft field always, the applicant (the first applicant) has successively applied for that on May 23rd, 2011 application number is 201110132789.2 and 201120164363.0 invention and utility model, applied for that application number is 201110372815.9 and 201120466520.3 invention and utility model on November 11st, 2011, its shortcoming is that skeleton structure is complicated, relatively poor, the lever operated relatively effort of elasticity, and the present invention has done further simplification and perfect on the basis of foregoing invention and utility model.

Summary of the invention

1. goal of the invention:

Realize the high-efficiency flapping wing of artificial wing, glide by the manpower run-up on the gradient and take off, perhaps glide by power-assisted manpower run-up on the level land and take off, can continue for a long time flapping flight and safe falling.The present invention provides a kind of more succinct efficient and practical pure manpower or the flapping wing aircraft of power-assisted for this reason, is expected to become the basic vehicle of human beings.

2. technical scheme:

This device and 201110132789.2,201120164363.0,201110372815.9,201120466520.3 invention are compared, whole Manpower beating wing aerial vehicle is further simplified, particularly cancel handle and replaced the stay cord pull bar, can set up driving engine as auxiliary power, the efficient of flapping wing and glide is higher, no longer need to movable accessory pinna be set at plain cotton fabric.

Overall technological scheme is as follows:

Wing Inner wing skeleton is the "the" shape decussate texture that a pair of elastomeric material is made, and intersects to be fixed on the push rod (19,20) that hollow pipe is used as flapping wing on stay cord (17, the 18) intermediate sleeve on the inner wing skeleton four arm ends.Promote the stay cord push rod downwards by staff and come downward flapping wing, upper flapping wing is then realized by the automatic recovery of elastomeric material skeleton.Small power motor is installed as auxiliary power, is conducive to the level land glide and takes off, remedy simultaneously the deficiency of manpower flapping wing, strengthen the power of climbing and the glide ability of flight.

Specifically explain orally below in conjunction with accompanying drawing.

Wing Inner wing skeleton is the "the" shape decussate texture (1,2,3,4,5) that a pair of elastomeric material is made.Intersect and to be fixed on the push rod (19,20) that hollow pipe is used as flapping wing on stay cord (17, the 18) intermediate sleeve on the inner wing skeleton four arm ends.The stay cord push rod (19,20) that connects stay cord (17,18) by downward promotion comes downward flapping wing, and upper flapping wing is then realized by the automatic recovery of elastomeric material skeleton.Inner wing skeleton and backrest are by wearing four pipes (8) and be connected and fixing.Can low power driving engine (6) be installed as auxiliary power at the cross tube of backrest.Outer wing (14) is the triangle of isosceles.As required, outer wing can be installed, also can not install.Outer wing size also can adjust flexibly as required.Rib is comprised of the vertical bar (9,10,11,12) of eight symmetries and the horizontal stripe (13) of two symmetries, perhaps is comprised of the vertical bar (9,11) of four symmetries and the rib (15,16) of four intersections and the horizontal stripe (13) of two symmetries.The equal K/UP of all ribs certain amplitude that arches upward, the assistant plain cotton fabric covers the whole aircraft surface except driving engine, is sewn to simultaneously on skeleton and all ribs and the backrest.Three small wheels (7) are housed on the sheer pole of backrest, hang simultaneously the canvas footmuff (21) of W shape.

The specific embodiment

The skeleton of this device adopts the elastomeric material manufacturing, and elastomeric material can use the light-duty new material of performance-oriented spring steel or equal performance.The stay cord push rod can use plastic pipe or stainless steel tube, aluminium-alloy pipe to make.Plain cotton fabric can use airfast Oxford cloth.According to the weight of human body and height and different in the size of concrete each parts.This specific embodiment take about the height 175cm, the human body of about 70 kilograms of body weight determines the size of each parts as example.

The span of present embodiment is 5-7 rice.The width of assistant is 2 meters.The span when only having inner wing is 5 meters.As required, outer wing can be installed, also can not install.Outer wing size also can adjust flexibly as required, outer blade area is at the 0.5-2 sq m.It is light that engine weight is wanted as far as possible, and power only needs 2-5 horsepower.After this aircraft used conventional material to make, complete machine comprised engine weight at the 9-17 kilogram, span 5-7 rice, blade area 10-12 sq m.If adopt the Novel light material, weight can be controlled at above-mentioned weight 1/4th within.

Be woven into safety harness with canvas or nylon tape in backrest, human body is shouldered whole aircraft by braces.By taking off run-up being arranged on the place of certain slope or glide by the auxiliary manpower run-up of driving engine on the level land.After taking off, both feet can be enclosed within on the footmuff of W shape, so that flight resistance reduces, center of gravity balance more.Come downward flapping wing by downward promotion stay cord push rod in-flight, loosen push rod then the elastomeric material skeleton restore and automatically go up flapping wing, can control freely the angle with pitching of turning to of wing by the stay cord push rod.
