Embodiment Construction

[0057] The device 1 according to the invention shown schematically in FIG. 1 serves to attenuate the influence of at least one vertical turbulence encountered by said aircraft during flight on an aircraft (not shown), for example a transport aircraft. It is known that turbulent flow corresponds to the agitation of the air consisting of constantly changing occasional motions superimposed on the average motion of the air. Turbulence is encountered in or near clouds (eg, in storm clouds, where there are simultaneously oppositely directed vertical airflows). Clear-air turbulence is also present near the ground or mainly at very high altitudes close to the jet stream.

[0058] According to the invention, said device 1 comprises:

[0059] at least one movable member 2, which is controllable and capable of contributing to the lifting of the aircraft;

[0060] means 3 , which will be described in detail below, determine at the current position of the aircraft the vertical component ...

Abstract

The invention concerns a device (1) comprising means (4) for determining automatically, using a vertical wind component, a level of severity concerning a vertical turbulence, and means (5) for computing automatically, using said vertical wind component, a control instruction for a controllable member (2), which enables the amplitude of load factors generated on the aircraft by the vertical turbulence to be minimized.

Description

technical field [0001] The invention relates to a method and a device for attenuating on board an aircraft the effects of at least one vertical turbulence encountered by this aircraft during flight. Background technique [0002] During flight, severe turbulence associated with vertical storms is known to cause at the aircraft level: [0003] - Significant changes in the vertical load factor capable of causing injury to the aircraft's occupants; [0004] - Significant swings in the altitude of the aircraft, thereby increasing the risk of collision with another aircraft; and [0005] - Lifting surges on the wings, which tax the wing load limits. [0006] These violent turbulences can occur in clear skies and remain unpredictable. Often, these local phenomena are unexpected by the aircraft's crew and on-board navigation systems, which do not have time for appropriate manipulations to mitigate the effects of these phenomena at the aircraft level. [0007] It should be noted ...
