초록

A method and systems are disclosed for reducing fluid flow noise. The method and systems use a thermal mechanism to deploy a flap edge fence during landing and/or other operating conditions, and stow the flap edge fence during other operational conditions such as cruise. The flap edge fence is controlled passively by ambient temperature or actively by a controller based on temperature changes corresponding to various operating conditions.

청구항

What is claimed is: 1. A system for reducing airflow noise for an aircraft having a wing main element, the system comprising: a flap coupled to the wing main element; a moveable flap edge fence coupled to the flap, said flap edge fence independently moveable with respect to said flap; and a control mechanism for the flap edge fence, the control mechanism being configured to: deploy the flap edge fence by moving said flap edge fence to a first position for a first set of flight conditions; and stow the flap edge fence by moving said flap edge fence to a ...
