Description
(54) УСТРОЙСТВО ЛЛЯ ОПРЕЛЕЛЕНИЯ АКУСТИЧЕСКИХ ХЛГАКТЕЕИСТИК СТРУИМЫХ МЗЛУЧЛП-Л : КОЛ НА ИМИ ОБРАТНОГО ДЕЙСТВИИ(54) DEVICE FOR THE ACUTE HOSE CHEMICALS OF OUTSTANDING MOUNTED ACOUSTICS: COLS ON THEIR REVERSE ACTION
ваетс изменением глубины резонатора 2 при помощи перемещени r.opaijm 3. Регистраци максимальной амплитуды ycHnejffloro звука производитсй регистрирующим прибором 6, например, катодным осциллографом, подкйзо 5 ченным к приемнику колебаний (микрофону) 5. С помощью гфедложенного устройства можно определ ть частоту срывающихс газовых вихрей при наличии высокоскоростного газового потока, обтекающего резонатор.юChanging the depth of the resonator 2 by moving the r.opaijm 3. The maximum amplitude of the sound is recorded by a recording device 6, for example, by a cathode oscilloscope attached to the oscillation receiver (microphone) 5. Using a device attached, you can determine the frequency of the firing gas beams in the presence of high-speed gas flow flowing around the resonator.
