Изобретение относитс  к коыпрессорстроению .This invention relates to co-compression.

Известны лопатки осевых компрессоров с С-образным профилем в сечени х по всей высоте лопатокKnown axial compressor blades with a C-shaped profile in the sections along the entire height of the blades

Недостатком известных лопаток нъл етс  резкое снижение устойчивости обтекани  в корневом и периферийном сечени х, сопровождающеес  пульсирующими срывами потоке и потес ми энергии.A disadvantage of the known blades is the sharp decrease in the stability of the flow in the root and peripheral sections, accompanied by pulsating disruptions of the flow and energy losses.

чение с S -образным профилем; сечение по Б-Б - среднее с С-образным профилем, сечение по В-В - корневое с б - образным профилем. S-shaped profile; B-B section is average with a C-shaped profile, B-B section is a root section with b - a shaped profile.

Такое выполнение лопатки обеспечивает повышение устойчивости обтекани  концзвых зон и уменьшение пульсаций потока, что дает снижение концевых потерь.This embodiment of the blade provides increased stability of the flow around the end zone and reduced flow pulsations, which results in a reduction in end losses.
