Description

The invention relates to aeronautical engineering and can be used to create light and sport aircraft or gliders.

Known aerodynamic steering of the aircraft with a compensator steering made in the form of a metal plate bent rigidly mounted on the rear edge of the steering wheel.

However, to eliminate the geometric and aerodynamic asymmetry of the aircraft in the track control channel, the compensator plate must be bent to either side manually or using a tool. At the same time, the rear edge of the steering wheel experiences palpable stresses. Especially this disadvantage is manifested on the rudders in the canvas error up to the violation of the connection of the sheathing with the rudder frame in the attachment zone of the compensator.

The aim of the invention is to improve the operational characteristics by

prevent rudder damage while adjusting the compensator.

The goal is achieved by the fact that the aerodynamic steering wheel of an aircraft (LA) with a steering compensator made in the form of a metal bent plate rigidly mounted on the rear edge of the steering wheel is equipped with a power U-shaped element forming a blunted rear edge of the steering wheel, and the compensator is made in the form of G shaped plate mounted removable with its shelf on the screws on the power of the U-shaped element with the possibility of permutation, while in the power of the U-shaped element set in response to the screws of the compensator anchor nuts.

FIG. 1 shows the aerodynamic steering wheel in the layout on an aircraft; in fig. 2 - section aa in fig 1.

The aerodynamic steering wheel 1 LA has a compensator 2, made in the form of an L-shaped bent plate mounted on the rear edge of the 3 steering wheel 1 The steering wheel 1 is equipped with a power U-shaped element 4 which forms

its blunt trailing edge 3. The compensator 2 is mounted removably with its shelf on the screws 5 on the power U-shaped element 4 with the possibility of permutation. On the power U-shaped element 4, anchor nuts 6 are fitted to the screws 2 of the compensator 2.

The device performs its functions as follows.

In case of asymmetry ЛА in the track control channel, a compensator 2 is installed on the blunted edge 3 of the steering wheel 1, which is screwed with screws 5. After measuring the symmetry of the aircraft in the track, the deflection of the pedals, the compensator 2 in the case of large deviations from the specified values turned upside down and rearranged, for which you need to unscrew the screws 5 and re-fasten the compensator 2. :: ..:. on the rear edge of the roll 3 1. If the asymmetry is not great, then the compensator 2 can be removed and bent on the fixture or manually. In this case, the rear edge 3 is not damaged and does not experience any additional loads.

Claims (1)

This is especially important if the steering wheel 1 has a paneling. Even if the rear edge 3 of the roll 1 with a sheet covering and has a power U-shaped element 4, the latter only strengthens the rear edge 3 itself, but does not prevent the case of monolithic mounting of the compensator 2 to the rear edge 3 of the latter bending relative to the weight of the roll 1 when adjusting compensator 2 directly on the steering wheel 1 without removing it. In the absence of asymmetry of the steering wheel 1, the compensator 2 is not installed. The presence of a blunted trailing edge 3 of the rudder 1 favorably affects the efficiency of the rudder 1 itself. Claims of the invention An aerodynamic rudder of an aircraft containing a rudder compensator made in the form of a metal bent plate rigidly mounted on the trailing edge of the rudder, characterized in that performance characteristics by preventing damage to the rudder when adjusting the compensator, the steering wheel is equipped with a power U-shaped element forming its dull trailing edge, and compensation The torus is made in the form of an L-shaped plate, which is installed removably by its shelf on screws on a power U-shaped element with the possibility of permutation, while in the power U-shaped element there are set anchor nuts corresponding to the screws of the compensator. / Aa
