Description
Technical field
A kind of flapping wing lift generating device belongs to the flapping-wing aircraft field.
Background technology
Human thirst for the imitation birds and act independently without seeking company, lightheartedly circle in the air on high, but realized the flight hope of oneself with looking for another way---all fruitful aircraft are not to have the wing (flapping wing) of instigating as birds, and perfect " wing theory " develops and be based on constantly.Human research's's " bionical flight " history is full of hardships and failure, and has the people to assert that the mankind can not realize flight by flapping wing.However, the modern who rushes across various rucial scientific and technological problems still is unreconciled to abandon " bionical flight ".In the view of them, to have only birds to circle in the air to be only personalized, it need not modern airport, long solid runway, huge logistics support.When you with " flapping-wing aircraft " and " ornithopter " centering, when outer patent database is retrieved, a large amount of related application can be presented in you at the moment; Medium were also reported some large-scale or miniature model machines, as, state's aviation Information Network reported once that " Canada realized having the people to drive ornithopter flight in 2006 9 months.This flapping-wing aircraft of taking a flight test is numbered C-GPTR, has carried out 3 times in July 8 the same year and sliding has run test, and realized in the sliding the last time race process liftoffly taking off and keeping.When this machine reach about 80 kms/hour coasting speed the time, the Aviatrix shifts throttle lever onto maximum position, this moment, the flapping wing frequency was 1 hertz, body has successfully left runway, and with about 89 kms/hour speed, about 1 meter height is flat forward on distance ground flew 10 seconds, 330 meters of total flying distances, airborne period has only 14 seconds." from photo as can be seen, what its adopted is connecting rod mechanism.
Http:// news.xinhuanet.com/On December 15th, 2003 was reported Nanjing Aero-Space University, and mini-sized flap wings aircraft that wing driver train makes has only 38 grammes per square metres to adopt three connecting rods to flutter, and can aloft fly 6 minutes, and flying height reaches 50 meters.
In fact, the Canadian flapping-wing aircraft that can not the original place rises and falls is not a flapping-wing aircraft truly; And the flapping-wing aircraft lift of Nanjing Aero-Space University is extremely limited, and useful load only is 38 grams; And both airborne periods are all very of short duration.Trace it to its cause and be: the flapping wing of instigating up and down can be offset a part of lift, inefficiency; In addition, the reliability of the multi-connecting-rod mechanism of high-speed cruising can be very not high yet.
Chinese patent " sliding closure lift generating device " (patent No. ZL200710071871.2) discloses a kind of flapping wing lift generating device.It is by " when being in inside respectively rotation of two rotating shafts in the same horizontal surface, stirring air because of outside two fins that slide of centrifugal action and move downward and produce lift." its weak point is: the span and the scope of fluttering that produces lift are subjected to the restriction of minimum chord length, fairing and arcuation fillet guide rail.

The present invention can also comprise:
1, a sleeve spring clamping mechanism is set on the lifting wheel, lifting arm is pumping in vertical guide by friction force at two lifting wheels.
2, two cover flapping wing lift generating devices are installed vertically on same flapping-wing aircraft, the phase difference that the flapping wing sheet of two cover flapping wing lift generating devices is fluttered is 180 °.
3, two rotational symmetry axles of fluttering are in the web member axis of lifting arm.
Flapping wing lift generating device of the present invention can by two in the longitudinal channels of axle of fluttering along laterally slide and the drive of the gear of fluttering under relatively the rectangle flapping wing sheet of unidirectional rotation produce lift, because of the span of flapping wing sheet and the scope of fluttering are fully utilized, thereby has higher efficient and bigger lift than flapping wing of instigating up and down and described Chinese patent (patent No. ZL200710071871.2).
Flapping wing lift generating device of the present invention is that the assembly that two nested structures are identical is fixed together axisymmetrically, and the total Chengdu of every cover comprises flapping wing sheet, baffle plate, the gear of fluttering, flutter axle, driven wheel, lifting arm and lifting wheel; Wherein, the flapping wing sheet is a baffled stiff rectangular plate in end; Flutter axle by two clamping flapping wing sheets and allow bar shaped clamping plate that the flapping wing sheet slides and two sections coaxial line spindle noses of end to form within it, install the gear of fluttering on the end spindle nose; Upper and lower two end positions that the flapping wing sheet slides in described bar shaped clamping plate lay respectively in the vertical guide, and are offseted and formed by the edge of baffle plate and bar shaped clamping plate; Do spacing with the driven wheel of the gear mesh of fluttering by belt pulley, drive motor and corner (or displacement) sensor and limit to rotation, guarantee to be in the smallest limit position after two flapping wing sheets all turn over 180 ° laterally from the limes superiors position, and in this process, produce lift; Lifting arm is " worker " character form component, and two lifting wheels are by the web member of a sleeve spring mechanisms grip lifting arm, and its pumping in vertical guide is to finish with the drive motor that links to each other with lifting wheel by friction force; The length of described web should be guaranteed: when the flapping wing sheet forwarded the smallest limit position to, lifting arm also arrived the smallest limit position, and at this moment, wing bar can be held the baffle plate of flapping wing sheet end under it; And when the lifting arm upward movement, can drive two flapping wing sheets, and arrive the limes superiors position simultaneously.
