Abstract: Изобретение может быть использовано в лазерной технике и, в частности в устройствах газодинамических СО 2 -лазеров. Способ создания инверсной населенности в газодинамическом СО 2 -лазере заключается в том, что организуют струйное перемешивание компонент в дозвуковой части сопла таким образом, чтобы полное перемешивание газов на мономолекулярном уровне произошло в районе критического сечения сопла. При этом параметры смешивающихся газов подбирают и поддерживают в процессе протекания реакций в заданном диапазоне такими, что создаются условия, когда при низкой статической температуре газов колебательная энергия вновь образующихся молекул в результате химических реакций накапливается в газе, передается молекулам реагирующих газов, увеличивая их скорость реакций. Увеличение скоростей химических реакций, в свою очередь, приводит к росту накопления колебательной энергии в молекулах смеси газов, при этом создаются условия выгорания в первую очередь СО и в меньшей степени Н 2 . В конечном счете в смеси газов активной среды газодинамического СО 2 -лазера оказывается существенно больше накопленной колебательной энергии, низкое содержание паров воды при меньшей статической температуре газов по сравнению с обычным газодинамическим лазером. Устройство содержит инжекторный узел камеры сгорания, установленный перед сопловым блоком и через отверстия которого осуществляется вдув холодного компонента газа. Отверстия инжекторного узла размещены на оптимальном расстоянии (L opt ) от района критического сечения сопел, определяемого из соотношения L opt  = ud 2 /D t , где u - скорость смеси газов в дозвуковой части сопла; d - характерный размер инжекторного устройства; D t  - коэффициент турбулентной диффузии. Сопловые лопатки имеют центральные каналы для охлаждения водой, которые стыкуются с подающим и сливным трубопроводами, а в дозвуковой части каналы с отверстиями инжектора для подачи холодного газового компонента в основной поток газа. При этом высота и площадка постоянного критического сечения сопел (h) должны удовлетворять соотношению h < τ       2   хим       (u/ν) 3 D       2   М       , где τ хим  - скорость химической реакции реагирующих газов; u - скорость смеси газов в районе критического сечения сопла; ν - кинематическая вязкость смеси газов; D М  - коэффициент молекулярной диффузии смешивающихся газов. Технический результат: повышение эффективности газодинамического лазера. 2 с. и 6 з.п. ф-лы, 4 ил.

Granted: 2018-07-12
Abstract: An expandable helical stent with a securement is provided. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other. The nestling of the undulation of adjacent helical coils contributes to maintaining the tubular shape of the helically coiled stent. In addition, the nestling of helical coils may prevent the polymer layer from sagging at any point between cycles of the helical coils.
