Description

сигнала достигаетс  регулировкой площади газопропускных окон 6 статора 5 за счёт их перекрыти  промежуточным цилиндрическим экраном 9, перемещаемым с помощью привода 11. Изменение значени  пространственной коррел ции достигаетс  регулировкой объема испытательной камеры с помощью стенки.the signal is achieved by adjusting the area of the gas passage windows 6 of the stator 5 due to their overlapping by an intermediate cylindrical screen 9 moved by the drive 11. The change in the spatial correlation value is achieved by adjusting the volume of the test chamber using the wall.

Использование описанного стенда позвол ет управл ть спектральными и коррел ционными характеристиками акустических нагрузок, что значительно расщир ет функциональные возможности устройства.Using the described bench allows you to control the spectral and correlation characteristics of acoustic loads, which significantly degrades the functionality of the device.
