Abstract

Estructura para mejorar el empuje del rotor de cola de un helicóptero, caracterizada porque comprende un elemento aerodinámico anular, delgado, sustancialmente planar, que tiene una abertura central con un diámetro aproximadamente igual al diámetro del rotor de cola; y una estructura que sostiene al elemento aerodinámico, de modo que la abertura sea coaxial con el rotor de cola y el plano del elemento aerodinámico sea esencialmente paralelo al plano de rotor de cola.
