Flap assembly of aircraft

Abstract

The invention discloses a flap assembly of an aircraft. The flap assembly comprises a flap and a driving component. The driving component comprises a rotation drive output device, a planar linkage rod mechanism and a pulling rod. One end of the pulling rod is hinged to a tail end of a planar linkage rod in the front of the pulling rod, and the other end of the pulling rod is hinged to a rear section of the flap in the back of the pulling rod and provided with a movement track. The linkage rod or / and a compression rod are hinged to a front section of the flap in a manner that hinge points are capable of moving along a set movement track. A swing parameter of the planar linkage mechanism is designed according to a movement track of the flap, a movement track limit is designed simultaneously according to the planar linkage mechanism and the movement track of the flap, a running track limit is designed according to the front section and the rear section of the flap, and a driving structure assembly is simplified to a greater degree. Furthermore, controlling precision of the driving structure assembly is improved by combing the planar linkage rod and the movement track limit, whole weight and size of the flap assembly are reduced, complexities of manufacturing, assembling and maintaining of the flap assembly are lowered, manufacturing cost and maintaining cost are reduced at the same time, and safe flight of the aircraft is facilitated.

Description

technical field [0001] The invention relates to an aircraft component, in particular to an aircraft flap assembly. Background technique [0002] Flap refers to a wing-shaped movable device on the edge of the wing of a modern aircraft. The flap can be installed on the trailing edge or leading edge of the wing, and can be deflected downward or (and) slide backward (forward). Its basic The effect is to increase the lift in flight; the main feature of the flap is that the flap is deflected and retreated at the same time. When the flap is lowered, it not only changes the camber of the wing, but also increases the effective area of ​​the wing at the same time. The upper gap has an effect on the airflow and the pressure distribution on the wing surface, so it has a very good effect on the increase of the aircraft. [0003] Since the most effective way for the flaps is to rotate around the axis while moving back and forth, and the control accuracy requirements are relatively high, ...

AI Technical Summary

Problems solved by technology

[0003] Because the most effective way for the flaps is to rotate around the axis while moving back and forth, and the control accuracy requirements are relatively high, so the drive structure of the prior art is relatively complicated, so the combination of each component has a large weight and is not conducive to Control accuracy, design, manufacture and installation are relatively complicated, which not only increases the cost of manufacturing and maintenance, but also adversely affects the normal flight of the aircraft
