Abstract

Przedmiotem wynalazku jest dysza wylotowa wentylatora/dysza wylotowa gorącego traktu turbiny gazowej charakteryzuje się tym, że zawiera trzy kierownice strug (2, 3), o wysokości do 30% promienia dyszy, usytuowane na zewnętrznym pierścieniu, co 120 stopni, których zadaniem jest redukcja zawirowań za pracującymi łopatkami, zmniejszenie strat ciśnienia i oporów ruchu, a także zmniejszenie hałasu jego pracy, jaki powstaje przy wysokich obrotach turbiny.The subject of the invention is a fan outlet nozzle / outlet nozzle for a hot gas turbine tract characterized by the fact that it has three jet blades (2, 3), with a height of up to 30% of the nozzle radius, located on the outer ring every 120 degrees, whose task is to reduce turbulence behind working blades, reducing pressure loss and resistance to movement, as well as reducing the noise of its work, which is generated at high turbine speed.
