Abstract
Disclosed is a sealing mechanism for plane wing surfaces, which comprises an upper sealing mechanism and a lower sealing mechanism which are mutually independent. The sealing mechanism comprises a rear sealing strip, sliding rails, pulleys, a pulley support arm, a middle sealing strip, a hinge and a front sealing strip. The sealing mechanism is assembled together with a wing and a flap in a rivet mode and capable of moving with flap deflection, so that a gap between the swing and the flap is effectively sealed, and sealing effect can be kept all along in the process of flap deflection. A jump between tail ends of the sealing strips and the swing is small, and movable sealing strips and the flap are connected in a hinge mode, so that the gap around the hinge and the jump are small, and aerodynamic performance of a swing surface and stealth performance of a plane are ensured. When the swing is folded, external surface contours of sealing strips are matched with the swing contour, so that optimal aerodynamic performance is guaranteed. When the wing is unfolded, smooth transition is achieved from the swing to the flap without sharp bevels, and air flow separation in high incidences is delayed, so that aerodynamic performance of the plane is ensured. The sealing mechanism is simple in structure and long in service life.
Description
Technical field
The present invention relates to the aircraft wing design field, specifically a kind of sealing mechanism for plane wing surfaces.
Background technology
In order to improve In-Flight Performance, the part present generation aircraft adopts the simple-type Leading-Edge Manoeuvre Flap at the leading edge of a wing at present.In the aircraft flight process, the extended position of wing flap is adjusted by rotary actuator automatically according to flying speed and the angle of attack.Rotary actuator is connected with wing flap with wing respectively by auricle.But, when dirty deflection, can produce very large ，Ci gap, gap between wing flap and main plane all has adverse effect to aircraft Stealth Fighter and aeroperformance.
At present the part aircraft adopts respectively one to be fixed to sealing band on wing flap to the sealing gap between wing and wing flap at top airfoil, lower aerofoil.In this scheme, the sheet metal that sealing band is a flexibility, make its end and the laminating of wing outside face by methods such as predeformation.At flap deflection thriving face on opportunity, can force sealing band to deform.The problem that this technical scheme exists is: one, because the actuator auricle is larger, near top airfoil sealing band auricle can upwarp when inclined to one side under wing flap, causes sealing band poorly sealed.Two, under wing flap partially the time distortion of lower aerofoil sealing band larger, because the position of droope snoot in the aircraft flight process is all changing at any time, after flight a period of time, sealing band can be because bending cracks repeatedly, the life-span is shorter.Three, the jump of the theoretical profile of sealing band end and aerofoil is large, affects the aircraft stealth effect.
No. 3974978 patent of the U.S. described a kind of staged blown flap, and its lower aerofoil at wing adopts a set of sealing mechanism to seal the gap between wing and wing flap.In this scheme, closing plate is connected with wing by hinge, and its end is fitted in the wing flap outside face, a spring is installed between sealing band and wing and is made sealing band end and wing flap keep laminating.Sealing band has certain elasticity, and in the flap deflection process, it is when hinge rotates, also under the effect at spring tension, producing certain bending, to set up a kind of continuous, level and smooth annexation between wing and wing flap.Yet the shortcoming of this scheme is: one, the suffered aerodynamic force of sealing band is larger, need larger spring tension guarantee sealing band end and wing flap laminating, this spring larger with regard to the elasticity of demand coefficient provides required pulling force, and therefore needed spring size is larger.But because wing is generally thinner, space anxiety between wing and wing flap, the spring that installation dimension is larger herein is more difficult.Two,, when the flap deflection angle is larger, the length that spring need to stretch is larger, the spring free length that this just need to be longer, and this has brought difficulty also to the application of spring.Three, because the elastic coefficient is larger, the space anxiety, the assembling of spring needs special tool, and this has just brought inconvenience to the I& M of this kind of sealing mechanism.Four, the hinge form between sealing band and wing is simple, causes between sealing band and wing still having larger gap, and this Stealth Fighter to aircraft also has larger adverse effect.Five, gasket structure is simple, can destroy the theoretical profile of Airfoil when the wing flap collapsed state, affects In-Flight Performance.
