Abstract

acoplamento aerodinâmico entre duas fileiras anelares de palhetas fixas dentro de uma turbomáquina. turbomáquina, que tem no mínimo duas fileiras anelares sucessivas de palhetas fixas formadas, por exemplo, pelas palhetas de um retificador (110) e por uma fileira anelar de braço de cárter (blindagem) (120) colocada à jusante do retificador, cada braço de cárter se estendendo sensivelmente em um plano radial que passa entre os bordos de fuga de duas palhetas fixas (112') adjacentes do cárter do retificador, e o passo (p1) entre estas duas palhetas fixas sendo superior ao passo (p2) entre as outras palhetas fixas (112) do retificador, de maneira a que os rastros (130) formados no nível das bordas de fuga destas duas palhetas fixas passem respectivamente de um lado e de outro do braço de cáter correspondente.
