Description

При работе сирены лента 3 движетс  и обеспечивает совмещение отверстий ленты с отверсти ми пластины 4. В момент совмещени  отверстий по всей площади рупора 2 происходит выброс сжатого воздуха из форкамеры 1 в полость рупора 2, на выходе которого происходит интерференци  волн, привод ща  к эффекту умножени  частоты акустических колебаний и расщирению спектра излучени  сирены.When the siren is operating, the tape 3 moves and aligns the holes of the tape with the openings of plate 4. At the time when the holes overlap over the entire area of the horn 2, compressed air is released from the pre-chamber 1 into the cavity of the horn 2, at the output of which interference occurs frequency of acoustic oscillations and expansion of the siren radiation spectrum.

Таким образом, описанна  сирена обеспечивает акустические колебани  в щироком диапазоне частот при достаточно широкой характеристике направленности излучени .Thus, the described siren provides acoustic oscillations in a wide frequency range with a sufficiently broad radiation directivity characteristic.
