Abstract

UN PROPULSOR PARA UN HELICOPTERO SE MONTA EN UNA PARTE TRASERA DE UN LARGUERO DE COLA (16). DOS CONJUNTOS DE PALAS DESVIAN UNA CORRIENTE DE AIRE QUE FLUYE A LO LARGO DEL LARGUERO DE COLA RESPECTIVAMENTE A LADOS OPUESTOS DEL LARGUERO DE COLA. DOS OBTURADORES (46, 48) SE DISPONEN GIRATORIAMENTE PARCIALMENTE ALREDEDOR DE LOS CONJUNTOS DE PALAS PARA DEJAR DOS ABERTURAS EN LADOS RESPECTIVOS DEL LARGUERO DE COLA. LOS OBTURADORES GIRAN A LA PAR APROXIMANDOSE O SEPARANDOSE PARA ABRIR/CERRAR LAS ABERTURAS RESPECTIVAS SIMETRICA Y SIMULTANEAMENTE DE TAL MODO QUE UN EJE LONGITUDINAL GEOMETRICO DE CADA ABERTURA PERMANEZCA ESTATICO CON INDEPENDENCIA DEL ESTADO DE LA ABERTURA.
