Description
Technical field
A kind of high-lift wing, belongs to vehicle technology field, particularly relates to a kind of high-lift wing.
Background technology
The surface of traditional wing is smooth, aerofoil profile has symmetric form and asymmetric, symmetric form is convex under epirelief substantially, and asymmetric have flat pattern or epirelief concave shape under epirelief, and within the scope of effective angle of attack, they can produce lift, the lift produced is limited, and effective angle of attack scope is little, when the angle of attack increases to a certain degree, the air-flow of its upper surface can produce separation, namely produces stall event, resistance rises suddenly, and lift declines suddenly.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming traditional wing, invent the high-lift wing that a kind of effective angle of attack scope is large.
A kind of high-lift wing, comprises wing body and rotating vane device.Wing body upper surface has a cross section like fan-shaped groove, the two ends of groove and the root of wing body and tip are provided with end plate, rotating vane device is arranged on groove and is built between the root end plate of wing body and tip end plate, and the inwall that the radius of groove just makes former and later two bus limits of the blade of rotating vane device all touch groove slides.The latter half of rotating vane device is all surrounded by groove, and the first half major part of rotating vane device exposes to above wing body.The aerofoil profile of wing body adopts thick wing type.The leading edge of wing body is more perfectly round, and trailing edge is more tapering.The curved surface of wing body upper surface for raising up except groove, lower surface is essentially plane or the curved surface slightly toward fovea superior.The concrete structure of rotating vane device is: rotating vane device comprises the identical rotating vane of the different structure of the setting angle of main shaft, center half gear and two that are evenly distributed on around the gear of center half, three or four only blade.The tooth of center half gear is not covered with whole circumference, only arranges half circumference, and another half circumference is anodontia smooth side, this smooth side lower than tooth paddy, in order to avoid touch this smooth side when the tooth of the nearly heart gear engaged with center half gear is below main shaft; Shorter than other teeth with the tooth depth of the transition tooth of the junction of anodontia half cycle with tooth half cycle, so that the nearly heart gear smooth transition engaged with center half gear.From the trailing edge of wing body toward leading edge, main shaft transverse horizontal is arranged vertical with tip end plate with the root end plate of wing body, and the right-hand member of main shaft is connected with tip end plate by bearing.Center half gear is fixedly mounted on the right side of root end plate, and upward, the anodontia half cycle of center half gear down for the band tooth half cycle of center half gear.The end portion that keeps left of main shaft is connected in the centre hole of center half gear by bearing and center half gear, and main shaft can flexible rotating in the centre hole of center half gear.The left end of main shaft stretches out outside the left side of wing body and the root of wing body, and power inputs from the left end of main shaft.Each rotating vane comprises arm axle, lobus sinister axle, nearly heart gear, arm axle sleeve pipe, heart gear, leaf-teeth wheel, blade, lobus dexter axle and pivoted arm far away.Blade is Rectangular Rigid plate blade.Structural relation between each component of same rotating vane is: lobus dexter axle transverse horizontal is arranged, the left end of lobus dexter axle is connected in the right center position of blade by bearing and blade, lobus dexter axle and blade are in same plane, and the right-hand member of lobus dexter axle is vertical with one end of pivoted arm to be connected.The lobus sinister axle left end that be fixed on lobus sinister axle vertical with arm axle, lobus sinister axle and lobus dexter axle coaxially transverse horizontal are arranged.Lobus dexter axle, pivoted arm, lobus sinister axle and arm axle are in same plane.The right-hand member of lobus sinister axle to be taken turns with leaf-teeth by bearing and is connected, and leaf-teeth wheel can around lobus sinister axle flexible rotating.Leaf-teeth wheel and blade are fixed on the center position on the left side of blade.Lobus sinister axle and blade are in same plane.Arm axle sleeve pipe is contained in around arm axle by bearing carrier ring, arm axle can in arm axle sleeve pipe flexible rotating.Nearly heart gear and heart gear far away are fixed on the two ends of arm axle sleeve pipe respectively.Heart gear far away and leaf gears meshing, the transmitting ratio that heart gear far away and leaf-teeth are taken turns is 2: 1.The part of the close right-hand member of main shaft is vertical with the pivoted arm of all rotating vanes to be connected.All pivoted arms are all in same longitudinal vertical guide.The left section of part near center half gear of main shaft is vertical with the arm axle of all rotating vanes to be connected.All arm axles are all in same longitudinal vertical guide.Nearly heart gear gear engagement in Shi Douyu center half above main shaft of all rotating vanes, the transmitting ratio of center half gear and nearly heart gears meshing is 1: 2.Center half gear, nearly heart gear, heart gear far away and leaf-teeth wheel all adopt finishing bevel gear cuter.During assembling rotating vane device, when guaranteeing that the arm axle of its arbitrary rotating vane is in vertical position directly over main shaft, the blade of this rotating vane and this arm axle are in same horizontal vertical guide, like this, because center half gear maintains static, and the transmitting ratio that center half gear and leaf-teeth are taken turns is 1: 1, this rotating vane goes to the blade of this rotating vane when arm axle is in any position above main shaft and is all in vertical state.Because the lower half of center half gear is anodontia, and because of the restriction of groove, rotating vane goes to the blade of this rotating vane when arm axle is in any position below main shaft and is all in the arm axle plumbness with this rotating vane.Vaned former and later two bus limits contacted with groove inner wall be provided with to reduce the antifriction cylinder that blade is close to groove inner wall cliding friction.
The principle of work of a kind of high-lift wing of this invention is: from the root of this wing toward tip, and power driven rotating vane device clockwise direction rotates, and the blade of rotating vane remains vertical with corresponding arm axle when the below of main shaft moves ahead, resistance is less; Blade is in vertical state all the time during rear row above main shaft, and the air-flow accelerating this upper surface of the airfoil to greatest extent flows backward.When this wing travels forward with the certain angle of attack within the scope of effective angle of attack, front incoming flow moves punishing two plumes close to leading edge, and main air is the below air-flow of this wing, and this air-flow velocity is substantially constant, suitable with front speed of incoming flow; Secondary air flow is the overhead stream of this wing, and this air-flow upwards flow to rotating vane device and is in acceleration flowing underneath backward under the agitating of rotating vane device turning near wing body leading edge place.Learn according to the continuity equation of fluid and Bernou1li equation, the top pressure of this wing much smaller than below pressure, thus produces larger lift.The rotating vane device of this upper surface of the airfoil can make air accelerate and comparatively be close to upper surface to flow to the back lower place, is not easily separated with the postmedian of wing body upper surface, the generation of deferrable tail.
The advantage of this wing compared with traditional wing is: maximum lift coefficient is large, and effective angle of attack scope is large, and critical stalling incidence is large, and maximum lift-drag ratio is large, and efficiency is high.
