Description
аппарата, причем на поверхности 4 обода 3 выполнены пр молинейные микроканавки 6, размещенные под торцами 7 сопловых лопаток под углом к оси турбины, равным углу установки сопловых лопаток на расчетном режиме.apparatus, and on the surface 4 of the rim 3 there are made straight micro-grooves 6 located under the ends of the nozzle blades 7 at an angle to the axis of the turbine equal to the installation angle of the nozzle blades in the design mode.
При вращении рабочего колеса 2, микроканавки 6 заполнены рабочим телом и сообщают .ему окружную составл ющую скорости Д по направлению вращени обода 3, противоположную направлениюWhen the impeller 2 rotates, the micro-grooves 6 are filled with a working fluid and inform it of the circumferential component of the velocity D in the direction of rotation of the rim 3, opposite to the direction

перетечек Д,т через радиальный зазор 5чх в РСА. Одновременно микроканзвки 6 создают дополнительное сопротивление вторичным течени м в корневой зоне межлопаточных каналов соплового аппарата , тем самым снижают вторичные потери .overflow D, t through a radial clearance of 5 h in the SAR. At the same time, microcanvas 6 create additional resistance to secondary flows in the root zone of the interscapular channels of the nozzle apparatus, thereby reducing secondary losses.
Предложенное устройство повышает КПД ступени газовой турбины с регулируемым сопловым аппаратом.The proposed device improves the efficiency of a gas turbine stage with an adjustable nozzle apparatus.
