На основе проведенного математического моделирования течения в этом патрубке установлено, что при входе в компрессор максимальная скорость на 36% превышает среднерасходную скорость, что серьезно сужает диапазоны устойчивой работы компрессора. Для решения указанной проблемы предлагается изменить конструкцию входного патрубка таким образом, чтобы в его проточную часть можно было установить разработанный новый эффективный гаситель неравномерности полей скоростей. Проведенные исследования показали, что таким образом коэффициент неравномерности удалось снизить с указанных выше 36% до 6%. </p></abstract><trans-abstract xml:lang="en"><p>The problem of ensuring a uniform velocity field at the air inlet to the first stage of the gas turbine compressor SGT5-2000E with an angular inlet path, that contains an inlet filter, a silencer and an angular intake flare, is considered. Based on the mathematical modeling of the flow in this flare, it was found that the maximum speed at the compressor inlet is 36% higher than the average flow rate. It leads to the fact that the range of stable operation of the compressor seriously narrows. To solve this problem, it is proposed to change the intake flare design so that a newly developed effective damper of uneven velocity fields is installed in its flow part. Studies have shown that in this way the nonuniformity coefficient was reduced from the above 36% to 6%. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>объемный гаситель неравномерности</kwd><kwd>коэффициент неравномерности</kwd><kwd>входной патрубок</kwd><kwd>компрессор</kwd><kwd>коэффициент сопротивления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>volumetricnonuniformity damper</kwd><kwd>nonuniformity coefficient</kwd><kwd>intake flare</kwd><kwd>compressor</kwd><kwd>resistance coefficient</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Stephen D.
