用于自动检测飞行器中的泄漏噪声的系统和方法
Abstract:
本发明提出了一种用于检测飞行器中的泄漏噪声的系统和方法，使得可以完全安全地并且在整个舱室加压范围内执行地面测试，从而避免必须采用多个飞行中测试，所述系统包括：至少一个获取装置(3)，其旨在安装在飞行器(11)的至少一个感兴趣的区域中，所述获取装置(3)被配置成获取与所述感兴趣的区域中的当前噪声有关的数据和与飞行器的舱室与外部之间的当前压力梯度有关的数据，以及监视装置(5)，其被配置成控制所述至少一个获取装置对数据的获取并且接收所述获取数据，以检测所述至少一个感兴趣的区域中的任何泄漏噪声。
Abstract(English):

The invention proposes a method and a system for detecting leak noise in an aircraft, making it possible to perform ground tests in complete safety and over an entire cabin pressurization range, thusavoiding having to resort to a plurality of in-flight tests, said system includes: at least one acquisition device (3) intended to be installed in at least one area of interest of the aircraft (11), said acquisition device (3) being configured to acquire data in relation to current noise in said area of interest and data in relation to a current pressure gradient between the cabin of the aircraftand the outside, and a monitoring device (5) configured to control the acquisition of the data by said at least one acquisition device and to receive said acquisition data in order to detect any leaknoise in said at least one area of interest.
