Abstract

Zespół łopatki sprężarki do gazowego silnika turbinowego zawiera przynajmniej jedną z czterech struktur kontroli strumienia przecieku, obejmujących osiowy łuk krawędzi natarcia (160) w pobliżu podstawy (128) łopatki, część (150) wewnętrznej platformy (132) wewnętrznej taśmy (86) wystającą do przodu i mającą zaokrągloną geometrię, ujemny wznios korpusu płata wzdłuż krawędzi natarcia (120) i w sąsiedztwie podstawy (128) i osiowy łuk krawędzi spływu (170) dla przynajmniej części krawędzi spływu (122) łopatki w pobliżu podstawy (128). Wspomniane struktury kontroli przecieku zwiększają sprawność roboczą turbiny, zapobiegając przeciekom od stopni sprężarki z wyższym ciśnieniem do stopni o niższym ciśnieniu.
