Изобретение относитс к турбомашино- строению и позвол ет повысить КПД. Это достигаетс путем организации потока рабочего тела вдоль каналов 6, выполненных на поверхност х пера 1 в направлении от входной к выходной кромкам 4 и 5. В зонах этих кромо к поверхность каналов 6 плавно сопр жена с поверхност ми пера 1. Каждый канал 6 имеет поперечное сечение в форме сегмента и на поверхности канала 6 нанесен регул рный микрорельеф. 1 з.п. ф-лы, 3 ил,The invention relates to a turbomachine structure and allows an increase in efficiency. This is achieved by organizing the flow of the working medium along the channels 6, made on the surfaces of the pen 1 in the direction from the entrance to the exit edges 4 and 5. In the areas of these chromosc to the surface of the channels 6, the surfaces of the feather 1 are smoothly joined a section in the form of a segment and on the surface of the channel 6 a regular microrelief is applied. 1 hp f-ly, 3 silt,
Description
Изобретение относитс к турбомашино- строению, в частности к лопатке турбома- шины.The invention relates to a turbomachine structure, in particular to a turbomachine blade.
Цель изобретени - повышение КПД.The purpose of the invention is to increase efficiency.
На фиг.1 показана лопатка турбомаши- ны; на фиг.2 - сечение А-А на фиг. 1; на фиг.З - сечение Б-Б на фиг.1.Figure 1 shows a turbomachine blade; 2 is a section A-A in FIG. one; on fig.Z - section bb in figure 1.
Лопатка турбомашины содержит перо 1 с выполненными на ее поверхност х 2 и 3 в направлении от входной к выходной кромкам 4 и 5 каналами 6, которые могут быть ориентированы вдоль линии тока. Каждый канал 6 имеет поперечное сечение в форме сегмента с радиусом R. Поверхности 7 каналов 6 в зоне входной и выходной кромок 4 и 5 плавно сопр жены с поверхност ми 2 и 3 пера 1. На поверхности 7 каждого канала 6 может быть выполнен регул рный микрорельеф .The turbomachine blade contains a feather 1 with channels 6, which are made on its surfaces 2 and 3 in the direction from the entrance to the output edges 4 and 5, which can be oriented along the streamline. Each channel 6 has a cross section in the shape of a segment with a radius R. The surfaces 7 of the channels 6 in the zone of the input and output edges 4 and 5 smoothly mate with the surfaces 2 and 3 of the feathers 1. On the surface 7 of each channel 6 a regular microrelief .
Во врем работы турбомашины поток рабочего тела движетс по каналам 6, которые организуют этот поток вдоль линии тока . Регул рный микрорельеф снижает аэродинамическое сопротивление обтекание поверхности каналов 6.During operation of the turbomachine, the flow of working fluid moves along channels 6, which organize this flow along the streamline. A regular microrelief reduces aerodynamic drag on the surface of the channels 6.
