Abstract

The invention discloses a flaperon which comprises a body (11). The body (11) conducts fixed-axis rotation around a rotating shaft (41). The flaperon further comprises a sealing plate (21) which is located above the body (11) and conducts fixed-axis rotation around a rotating shaft (42). A supporting arm (23) is fixedly connected to the lower side of the sealing plate (21), and a rolling wheel (24) is fixed to the tail end of the supporting arm (23). A guide rail (25) is fixed to the flaperon body (11). The rolling wheel (24) is matched with the guide rail (25) and can move along the guide rail (25). Compared with a conventional flaperon, the flaperon is advantageous in that the follow-up sealing plate is added above the flaperon body, so that airflow of the trailing edges of wings is improved, and the efficiency of the flaperon is increased.

Description

A kind of flaperon

Technical field

The invention belongs to aircraft wing structure field, be specifically related to a kind of flaperon.

Background technology

The flaperon of aircraft, generally all does dead axle yaw motion. After flaperon deflects motion, forming seam road between flaperon and trailing edge top airfoil, for this seam road, widespread practice is both at home and abroad at present, self-assembling formation seam road between flaperon and the fixing trailing edge of wing after deflection. The seam road of self-assembling formation influences whether the air-flow of trailing edge, and then has influence on the effect of flaperon.

Summary of the invention

The technical problem to be solved in the present invention is in that, controls the seam road between trailing edge and flaperon body, thus improving the aeroperformance of wing, improves the efficiency of flaperon.

A kind of flaperon is provided for solving the problems referred to above technical solution of the present invention, including body, described body does fixed-axis rotation around the shaft, it is characterised in that, also include sealing plate, described sealing plate is positioned at above described body, rotates in fixed axis around the shaft, is fixedly connected with support arm under described sealing plate, described leg extremities is fixed with roller, being fixed with guide rail on described flaperon body, described roller and described guide rail agree with, can along guide rail movement.

Preferably, described guide rail constraint sealing plate deflection, and then control described sealing plate with the break joint road size of body.

Flaperon of the present invention is positioned at trailing edge, both can make wing flap, can make again aileron, is used as wing flap when the flaperon of wing both sides all deflects down time, is used as aileron when the flaperon yawing moment of wing both sides is contrary. This invention flaperon mainly includes flaperon body and flaperon sealing plate, and both does fixed-axis rotation. The flaperon of the present invention, compared to conventional flaperon, adding a servo-actuated sealing plate above flaperon body, thus improving the air-flow of trailing edge, improve the efficiency of flaperon.

Detailed description of the invention

The embodiment of the present invention is discussed in detail below in conjunction with accompanying drawing:

As it is shown in figure 1, after flaperon body 11 is positioned at trailing edge 1,41 do dead axle motion around the shaft. Rotating shaft 41 is provided by suspension joint 12, and suspension joint 12 stretches out below trailing edge 1, and front end is fixing with wing rear spar 2 to be connected. The flexible of actuator 51 that move through of flaperon body 11 realizes, and the front end of actuator 51 is hingedly connected on wing rear spar 2 by joint 52, and rear end is connected through the hinge with flaperon body 11 at point 53 places. Must having certain distance between axis and the rotating shaft 41 of actuator 51 so that actuator 51 countershaft 41 produces rotating torque, so, when actuator 51 extends, flaperon body 11 deflects down, and during shortening, flaperon body 11 upward deflects.

Flaperon sealing plate 21 is positioned at after trailing edge 1 and on flaperon body 11, and fixed-axis rotation is done in the rotating shaft 42 around its front end. Rotating shaft 42 is provided by joint 22, and joint 22 is connected with trailing edge 1. The motion of flaperon sealing plate 21 is the follower of flaperon body 11 motion, and the component of follower mainly includes support arm 23, roller 24 and guide rail 25. Support arm 23 is positioned at below flaperon sealing plate 21 and is connected with it, and support arm 23 end is equipped with roller 24, and roller 24 rolls along guide rail 25, and guide rail 25 is connected with flaperon body 11. The shape of guide rail 25 is in order to control flaperon sealing plate 21 constantly with the seam road between flaperon body 11.

Fig. 4 and Fig. 5 show the present invention specific embodiment for certain aircraft.

As shown in Figure 4, this flaperon is made up of wing flap body 101 and flaperon sealing plate 102. Flaperon body 101 does fixed-axis rotation, two groups of hinges support, respectively hinge 111 and hinge 112. The motion of flaperon body 101 is driven realization by actuator 115 and actuator 116, and the driving of actuator 115 and actuator 116 synchronizes, and when any one breaks down, another motion remaining to handle flaperon.

As it is shown in figure 5, flaperon sealing plate 102 is positioned at the top of flaperon body 101, also do fixed-axis rotation, 5 groups of hinges support, respectively hinge 121, hinge 122, hinge 123, hinge 124 and hinge 125. Overlap follower by two between flaperon sealing plate 102 with flaperon body 101 to be connected, two set followers lay respectively at the two ends of flaperon, as shown in Figure 4, the servo-actuated component in left side includes support arm 103, slide rail 104 and roller 105, as it is shown in figure 5, the servo-actuated component in right side includes support arm 106, slide rail 107 and roller 108.

The operation principle of flaperon of the present invention is: when actuator 115 and actuator 116 extend, flaperon body 101 does downwards dead axle deflection around hinge 111 and hinge 112 under thrust, simultaneously, flaperon body 101 move through the roller 105 rolling in slide rail 104 and the roller 108 rolling in slide rail 107, pass to flaperon sealing plate 102, flaperon sealing plate 102 is driven also to do downwards dead axle deflection around hinge 121, hinge 122, hinge 123, hinge 124 and hinge 125, now, flaperon plays the effect of wing flap, and it is contrary that it packs up process. When actuator 115 and actuator 116 shorten from zero-bit, flaperon body 101 upwards does dead axle deflection around hinge 111 and hinge 112 under the effect of pulling force, simultaneously, flaperon body 101 move through the roller 105 rolling in slide rail 104 and the roller 108 rolling in slide rail 107, pass to flaperon sealing plate 102, flaperon sealing plate 102 is driven also upwards to do dead axle deflection around hinge 121, hinge 122, hinge 123, hinge 124 and hinge 125, now, flaperon plays the effect of aileron, and it is contrary that it packs up process.

Flaperon of the present invention, by increasing servo-actuated flaperon sealing plate above the flaperon body of fixed-axis rotation, controls the gap between flaperon and wing constantly, thus improving the aeroperformance of wing, improving the efficiency of flaperon.
