AIRCRAFT WING FLAP SUSPENSION SYSTEM Russian patent published in 2024 - IPC B64C9/02 B64C9/20 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, namely to the design of the tilt two-section single-slot flap suspension system of the wing of a large-span aircraft, which can be used in designing wide-body long-range aircraft. Aircraft wing flap suspension system includes a two-section single-slot tilt flap consisting of an inner section and an outer section and flap suspension assemblies. At that, the inner section is fixed on the wing by means of two suspension assemblies having a single kinematic axis of rotation and equipped with a drive for transmitting the movement of the inner section of the flap. Outer section is fixed on wing by means of three suspension assemblies, each of which has its own kinematic axis of rotation. At that, some suspension assemblies are equipped with a drive for transmitting movement of the outer section of the flap, and the other suspension assembly performs a supporting function and does not contain a flap motion drive.

EFFECT: reducing the weight of the flap suspension system structure due to the kinematic simplicity of the mechanism, reducing the number of suspensions for the outer section of flap to 3, without dividing the section into two parts, instead of 4 (at dividing the outer section into two parts), transfer of forces from the flap to the wing along the shortest distance.
