Abstract

Un rotor destinado a un empleo, no sometido a la influencia de cajas o canales estacionarios conductores de corriente, en un medio de corriente que se encuentra en un espacio ilimitado en comparación con las dimensiones del rotor, en particular para una máquina eólica o para un helicóptero o un autogiro dotado de una corona de paletas de rotor y de una envolvente dispuesta en la zona de la periferia exterior del rotor y configurada como envolvente anular exterior asimétrica axialmente y que gira juntamente con el rotor, caracterizado porque la envolvente anular exterior (2) en una sección trazada en un plano ideal que discurre a través del eje (1) del rotor, presenta un perfil (GP1 ó GP2 ó GP3 ó GP4), cuyo ángulo de paso es mayor que el ángulo de paso crítico (de desprendimiento) del perfil, referido a una corriente que discurre en sentido paralelo al eje del rotor, y que, en caso de un ataque de corriente efectivo dado al girar el rotor en la zona de la velocidad periférica de servicio, esadecuado para generar un empuje ascensional y está orientado de tal manera que su lado de interior de la envolvente anular.
