Abstract

PÁ DE VENTOINHA DE TURBOJATO. A invenção é relativa a uma pá de ventoinha de turbojato. O bordo de ataque da pá apresenta um ângulo de flecha maior do que ou igual a +28° em uma porção da pá que está situada em uma altura radial que se situa na faixa de 60% a 90% da altura radial total da pá, medida a partir de sua raiz no sentido de sua ponta e o ângulo de flecha de bordo de ataque apresenta uma diferença ((delta)1) de menos do que 10 graus entre um ângulo de flecha mínimo medido em uma altura radial (Hmin) de ângulo de flecha mínimo situado na porção da pá que se situa na faixa de 20% a 90% da altura radial da pá e um ângulo de flecha medido em uma altura radial (Hmin+10) que é 10% maior do que dita altura radial de ângulo de flecha mínimo.
