Description
Technical field
The present invention relates to aeroplane structure design field, relate in particular to a kind of spring loaded wing flap sealing mechanism.
Background technology
The maneuver flap of aircraft wing leading edge is generally driven by rotary actuator, and rotary actuator is connected with wing flap with wing by auricle respectively.When dirty deflection, between the front part of a Chinese robe or jacket and main plane, can produce very large gap, this gap all has adverse effect to aircraft Stealth Fighter and aeroperformance.
At present part aircraft adopts one to be fixed to closing plate on wing flap to the sealing gap between wing and wing flap, and sealing plate is the sheet metal of a flexibility, by methods such as predeformation, its end and wing outside face is fitted.Under wing flap, opportunity, thriving face can force lower seal plate to deform partially.The problem existing is at present: because actuator auricle is larger, near top airfoil closing plate auricle can upwarp and cause closing plate poorly sealed when inclined to one side under wing flap.In addition, under wing flap, the distortion of lower aerofoil closing plate is larger partially time, and in aircraft flight process its maneuver flap position with state of flight real-time change, make closing plate within the shorter flight time, bear the bending repeatedly of more number of times, thus, closing plate can crack and destroy very soon, and the life-span is shorter.
No. 3974978 patent of the U.S. adopts mechanism type sealing arrangement to above-mentioned sealing gap at lower aerofoil.In this scheme, closing plate is connected with wing by hinge, and its end is fitted in wing flap outside face, so seals the gap between wing and wing flap.A spring is installed between closing plate and wing makes closing plate end and wing flap keep laminating; On closing plate, have a spring support arm, a spring hanger is equipped with in wing lower aerofoil inner side; Spring end is connected on the spring hanger of wing lower aerofoil inner side and the spring support arm of closing plate.
China ZL201210031514.4 patent has proposed a set of sliding track mechanism formula sealing arrangement, and it comprises upper and lower two cover sealing mechanisms.In this scheme, slide rail is installed in wing inner side, and closing plate is arranged on wing flap by built-in hinge and is overlapped on wing outside face, and roller support arm is equipped with in closing plate inner side, utilizes pulley-sliding track mechanism that closing plate end is fitted with wing outside face all the time.
For No. 3974978 patent of the U.S., due in engineering reality between wing and wing flap space comparatively nervous, make that larger spring is installed herein more difficult.When 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.In addition, the hinge form in this scheme between closing plate and wing is simple, causes still having larger gap between closing plate and wing, and this can also have larger adverse effect to the stealthy new of aircraft.
There is following shortcoming in China ZL201210031514.4 patent: 26S Proteasome Structure and Function principle is complicated, and member is more; For guaranteeing that closing plate end can fit tightly with wing, needs higher sliding track mechanism working accuracy; Because aircraft wing thickness is successively decreased to wing tip direction by wing root, and generally there is torsion in wing, and making the closing plate characteristics of motion is complicated space motion, caused difficulty to design and the processing of sliding track mechanism; Because the plate of obturaging is space motion, in the plate motion process of obturaging, need to produce a small amount of torsion, for guaranteeing sealing effectiveness, in spanwise, need to arrange a plurality of sliding track mechanisms, cause sleeve mechanism weight larger.
In view of above-mentioned defect, creator of the present invention has obtained this creation finally through long research and practice.
Summary of the invention
