Description
Technical field
The present invention relates to the Flight Vehicle Design field, specifically is the flexible aileron of a kind of inflatable.
Background technology
In flight course, the rolling movement of aircraft often depends on the control of aileron on the wing.The aileron design is crucial link in the Flight Vehicle Design, is related to the stability and the manoevreability of flight, and these two aspects are again to judge the important indicator of aeroplane performance just.Especially the all-wing aircraft layout aircraft of anury formula, in order to realize the controllable flight of vertical, horizontal, guarantee the stability and the manoevreability of flight, need more controlsurface to participate in flicon, nearly eight pairs of controlsurfaces are for example just arranged on the B2 strategic bomber of the U.S., and its design, processing and control are all very complicated.
Traditional aileron all is that the relative deflection by the part aerofoil changes the air flow direction on the wing, with this air dynamic behaviour that obtains to expect.The deflection of aileron is generally finished by the steering wheel of hydraulic efficiency pressure system or certain power.In these systems, hydraulic-mechanic system especially, not only weight and volume is all bigger, and is not easy to design and installation.Because aileron is installed on the very little trailing edge of thickness usually, airplane design person have to heave the drive system that a convex closure is settled aileron on aerofoil sometimes, and this obviously can influence the aerodynamic characteristic of wing, thereby influences driving efficiency.
In addition, the stealthy performance of modern operation aircraft lay special stress on, and have the gap between traditional aileron and the wing aerofoil inevitably, when aileron is opened, angle between aileron and the aerofoil is bigger, and this will bring strong corner reflection problem, is unfavorable for the stealthy design of aircraft.
Summary of the invention
For overcome exist in the prior art or design, processing and control all very complicated, perhaps can influence the aerodynamic characteristic of wing, thereby influence driving efficiency, perhaps be unfavorable for the stealthy design-calculated deficiency of aircraft, the present invention proposes a kind of inflatable flexibility aileron.
The present invention includes the flexible aileron of the inflatable that sticks on both sides upper surface of the airfoil and lower surface.
The flexible aileron of inflatable is the rectangle air bag made from elastomeric material; A surface of the flexible aileron of inflatable is a stickup face; Tangential 1.5%～7% wing chord length that is of a size of of the flexible aileron of inflatable, exhibition is to being of a size of 9%～22% of wing exhibition length; The trailing edge of the flexible aileron of inflatable is 0%～10% a wing point chord length apart from the trailing edge of swept back wing 1; The left end of the flexible aileron of inflatable is that the exhibition of 2%～10% wing is long apart from the wing wing tip; Air compressor is positioned at fuselage interior, is connected with the flexible aileron of the inflatable that is positioned at two upper surface of the airfoils and lower surface respectively.
Centre at the stickup face of the flexible aileron of inflatable has air extractor vent, is with hollow bolt on air extractor vent; The flexible aileron air extractor vent of through hole on the covering section and inflatable is a concentric holes.Air compressor is connected by breather line with the air bag admission port; The air bag admission port is connected with the electromagnetic valve admission port; Three tube heads of three-way pipe are connected with two electromagnetic valves with hollow bolt respectively; Air bag admission port and air bag air extractor duct are connected in series with electromagnetic valve respectively.The external peripheral surface of hollow bolt has screw thread; Spiro cap is contained on the hollow bolt, nut is packed in the through hole on the covering section, and make the flexible aileron of inflatable have 7%～14% initial elongation amount.
Air compressor of the present invention is positioned at fuselage interior.Air compressor is connected with the air bag admission port by breather line; Be serially connected with electromagnetic valve respectively on air bag admission port and the air bag air extractor duct.Three tube heads of three-way pipe are connected with two electromagnetic valves with hollow bolt respectively.
The inflation and the deflation course of the flexible aileron of inflatable are controlled by electromagnetic valve; Electromagnetic valve is not in open mode when having voltage.When the flexible aileron of inflatable was inflated, the power supply that disconnects electromagnetic valve on the admission port made air inlet open, connects the power supply of electromagnetic valve on the air extractor duct, and air extractor duct is closed; When the flexible aileron of inflatable is exitted, the electromagnetic valve closure on the admission port, the electromagnetic valve on the air extractor duct is opened.The flexible aileron of four inflatables all has a pair of electromagnetic valve 14 to be used to control the filling of the flexible aileron of inflatable, bleed air operation.
The present invention utilizes aerodynamic principle, and near a kind of inflatable structure of mounted on surface trailing edge, this structure are pasted by elastomeric material and formed.Elastomeric material is selected the material of the big and good airproof performance of modulus of elasticity for use.When needs use aileron, elastomeric material inside is carried out pneumatic compression by gas filled device.Under the effect of internal pressure, the air bag volume that elastomeric material is made increases, and air bag has changed the aerofoil surface shape from the aerofoil surface upper process, streams the flow field thereby influence it, obtains the aerodynamic force of operating aircraft attitude and control aircraft flight.
Among the present invention, the shared cover air inflator system of each air bag.When certain operating torque of needs, choose corresponding air bag, charge into the gas of a constant volume, it is sticked out from aerofoil.Can bring the flow field to change by the verified air bag of heaving of test, obtain required aerodynamic force moment, its effect of the manipulation is identical with traditional mechanical formula controlsurface, be that the flexible aileron of inflatable can substitute traditional mechanical type aileron, and do not destroy the integral structure of aerofoil, there is not the slit, can reduces radar return, help improving the stealthy performance of aircraft.Compare with traditional mechanical formula aileron, the present invention has lightweight construction, aerofoil is smooth and the characteristics of convenient processing and maintenance.
