Description

Airplane wing with lift flap There are devices for adjustment known from aircraft auxiliary wings, in which the auxiliary wing comes from the main wing can be pushed out to the rear and for which the Setting the auxiliary wing: done. In particular, esc: bla; 19 en, with the help of two slanting guide tracks very gradually during to adjust the auxiliary wing to the extension movement. The disadvantage here is that at low employment of the auxiliary wing for the take-off only part of the additional Area of the wing only fully extended in the braking position at the time of the lift is available.

Furthermore, aircraft wings are with retractable and Auxiliary wing that can be adjusted in relation to the main wing is known in which the auxiliary wing - by means of swivel arms extended to the rear and by mixing these swivel arms and the auxiliary wing provided links is employed. By forcibly Coupling of swiveling movement and tilting movement is only possible here with two Laben the auxiliary wing reached a favorable gap distance. Is also disadvantageous the lateral displacement of the auxiliary wing caused by the S, chw, enkbewegung @ in the retracted and extended state.

It is also known to extend and adjust the auxiliary wing to be carried out by separate bodies. Here, the auxiliary wing can be fully extended Condition can be knocked out in any way with favorable gap conditions, however, the handling of such a Fowler wing is relatively demanding a lot of attention from the pilot and is also somewhat unfavorable.

The present invention avoids the disadvantages of the above Facility According to the invention, an aircraft wing with a rearward extendable and against the main wing anstellba.rem auxiliary wing proposed, which has the union of the following features: a) The auxiliary wing is extendable Supports (skewers or trolleys) rotatably mounted and with these extendable supports bite extendable to a stop on a straight or curved path: b) The The main wing has guide strips and the auxiliary wing has corresponding guide rollers, which is a downward rotation of the auxiliary wing during the dropout movement prevent and allow at the end of the extension movement. c) A preferably hydraulic one or electrical actuator engages with a lever arm above the Support of the auxiliary wing directly on the auxiliary wing and initially causes the extension and after the completion of the extension stroke en stronger adjustment of the auxiliary wing.

A facility of the same kind in principle is also created, Zvenn the hydraulic or electrical actuation device on the extendable support attacks and the auxiliary wing is provided with a stop outside its axis of rotation through which the adjustment movement takes place shortly before the end of the extension stroke. The extendable supports (spit or cart) can also be provided with stops - which secure the auxiliary wing against turning upwards.

The invention is explained in more detail with reference to Figs.

Fig. I shows in section the rear end of an aircraft wing with an auxiliary wing that can be extended to the rear by means of spikes.

Figure 2 also shows a section of the rear end of an aircraft wing with a lying auxiliary wing that can be extended to the rear.

In Fig. I i represents the wing, the one that can be extended to the rear Auxiliary wing 2 is sunk. The solid lines show the auxiliary wing in its The extended and dashed lines show it in its extended and salaried location. The auxiliary wing can be displaced at the end of between guide rollers 3 Poles or skewers. mounted and rotatable about axis 5. Above this axis of rotation 5 engages the piston rod at pivot point 6; of the hydraulic device 8. The auxiliary wing is also provided with a guide roller at its front end, which can run on a guide track fixed in the main wing. Slides last The end of the guideway io 'is strongly upwards for the employment of the auxiliary wing kinked: in addition, the skewer .1 can still be equipped with a not shown in the figure Be provided with a stop to prevent the auxiliary wing from swinging upwards.

The operation of the device is readily apparent from the figure evident. If the hydraulic cylinder 8 is pressurized, let it move the auxiliary lie1 2 to the rear, whereby the lever aria between the axis of rotation 5 and attack torque 6 exerted torque by the roller g and the guide track i o resign: oninicn will. At the end of the extension stroke, the roller 9 slides on the above bent part i o 'of the guideway upwards, m-od through the auxiliary wing receives his employment. If the skewer is provided with a stop that his Extension stroke to the rear limited to the moment, zero. the leadership role has reached the bent part io 'of the guideway, so @ one can. the guideway Form iö as a circular arc with the center of curvature at 5 '.

In the embodiment in Fig.2, one is also used on the auxiliary wing in the pivot point ü attacking hydraulic device 8 for extending and adjusting of the auxiliary wing. Instead of management posts as in Fig. I, a carriage is used i i as a support for the auxiliary wing 2, which can be extended to the rear in guide tracks 1a is. The guide carriage i i is also provided with a stop at its rear end 13 provided, through which an upward rotary movement of the auxiliary wing is avoided. The longitudinal extension and pitch movement of the auxiliary wing is also used here the guideway i o or i o 'is reached by the guide roller g imd.
