Description
где поглощаютс мatepиaлoм и выход т после глушител зна 1иМльно ослабленными .where absorbed by the materiel and exiting the silencer are 1 and MILLY weakened.
Равномерна толщина лопатки йо длине и наличие наклонной боковой поверхности способствуют увеличению эффективности глущени как за счет посто нного частотного затухани , так и за счет искривлени поверхности.The uniform thickness of the blade yo to the length and the presence of an inclined lateral surface contribute to an increase in the effectiveness of damping, both due to constant frequency attenuation, and due to the curvature of the surface.
Лабораторные испытани данной конструкции показали, что эффективность ослаблени звука на средних частотах (500- 1000 Гц) повысилась но сравнению с известным глущителем на 2-4 дБ без изменени габаритных размеров по длине.Laboratory tests of this design showed that the efficiency of sound attenuation at medium frequencies (500-1000 Hz) increased, compared to the known attenuator, by 2-4 dB without changing the overall dimensions in length.
