Известны осевые турбомашины, например гидроиашиныили насосы, содержащие заключенный в корпус над с заклепленныии на ней лопаст ми .Axial turbomachines are known, for example, hydromachines or pumps that contain blades enclosed in the hull over with riveted on it.

Предложенна  турбомашина отличаетс  тем, что ее рабочие лопасти снабжены одним или несколькими про1)ильными ребрами, установленными на одной или обеих поверхност х , дл  того, чтобы обеспечить смыв основным потоком набухшего пограничного сло  с лопасти до смыкани  или взаимодействи  его с пограничным слоем соседней поверхности .The proposed turbomachine is characterized in that its working blades are provided with one or more pro1 ribs mounted on one or both surfaces, in order to ensure that the main stream is flushed from the blade to closure or interacting with the boundary layer of the adjacent surface.

На чертеке пскавана принципиальна  схема сребренной лопасти дл  рабочего колеса гидромашины.The schematic diagram of the cut-off blade for the impeller of the hydraulic machine is shown in the drawing.

На выпуклой, вогнутой или обеих сторонах лопасти 1 устанавливают ребра Z (одно или несколько), орма поперечного сечени  ребра и его расположение относительно поверхности лопасти могут быть рааличны . 3 плане ребра расположены по лини м, соваадащим с расчетными лини ми потока или близких к ним, т.е. дл  осевых турбомашин -поOn the convex, concave or both sides of the blade 1, Z edges (one or more) are installed; the shape of the cross section of the rib and its location relative to the surface of the blade can be different. In terms of the 3 planes, the edges are located along lines coinciding with or close to the calculated flow lines, i.e. for axial turbomachines

окруасности.- Высота ребра относительно толщины пограничного сдо  увеличиваетс  от входной к выходной кромке.around the edge. The height of the rib relative to the thickness of the border is increased from the entrance to the exit edge.

Применение турбомашины с оребренными лопаст ми позвол ет uasnf сить её к. п.д. как на расчетном, так и на нерасчетном рехимах, а также приблизить энергетические характеристики к расчетным. 1фомеТОГО , повышаетс  жесткость и прочность лопастей и увеличиваетс  быстроходность турбомашины.The use of a turbomachine with ribbed blades allows uasnf to drive it to the airfield. both on calculated and off-design rehims, and also to bring the energy characteristics to the calculated ones. 1F, the rigidity and strength of the blades increase and the turbomachine speed increases.

Осева  или диагональна  Турбомашина , например гидромашина, содержаща  заклшенный в корпус вал с закрепленными на нём раоочими лопаст ми , ОТЛИЧАЮЩАЯСЯ тем, что, с целью повышени  аэродинамических качеств проточной чаоти и к.п.д. установки, лопасть снабкена одним или несколькими профильными ребрами, установленными на одной или обеих её поверхност х вдоль движени  основного потока дл  смыва пограничного сло .An axial or diagonal Turbomachine, for example, a hydraulic machine, containing a shaft that has been hardened into the housing with fixed blade blades on it, DIFFERENT THAT, in order to improve the aerodynamic qualities of flow through chathi and efficiency installation, the blade is equipped with one or more profiled ribs mounted on one or both of its surfaces along the main flow for flushing the boundary layer.
