Abstract
EL CONTROL DE LAS ARMONICAS SUPERIORES (DE AQUI EN ADELANTE HHC) DE LAS VIBRACIONES DE LAS PALAS DEL ROTOR DE UN HELICOPTERO SE CONSIGUE MEDIANTE UN CILINDRO RANURADO, ROTATIVO, ACTIVAMENTE CONTROLADO (11) QUE SE ENCUENTRA MONTADO EN UNA SECCION EXTERIOR DE CADA PALA (12). LA ROTACION CONTINUA DE CADA CILINDRO (11) ALREDEDOR DE SU EJE LONGITUDINAL PRODUCE UNA FUERZA AERODINAMICA PERIODICA EN LA PALA (12) A UNA FRECUENCIA DOS VECES MAYOR QUE LA FRECUENCIA DE ROTACION DEL CILINDRO. LA INTENSIDAD DE LA FUERZA QUEDA CONTROLADA POR EL TAMAÑO DE UNA ABERTURA RANURADA (110,111,112,133) QUE HAY FORMADA EN EL CILINDRO MIENTRAS QUE LA VELOCIDAD DE ROTACION DEL CILINDRO SE SINCRONIZA PARA QUE CORRA A UN MULTIPLO DE LA VELOCIDAD DEL EJE ACCIONADOR DE LA PALA DEL ROTOR. LA INTENSIDAD Y LA FASE DE LA FUERZA DE HHC SE REGULAN, BIEN MANUALMENTE O BIEN MEDIANTE UN CONTROL DE REALIMENTACION ACTIVO, PARA MINIMIZAR CUALQUIER CARGA VIBRATORIA TRANSMITIDA AL FUSELAJE A TRAVES DEL EJE ACCIONADOR DE LA PALA DEL ROTOR. UNA VENTAJA SIGNIFICATIVA OFRECIDA POR ESTE CONCEPTO, RELATIVA A OTROS METODO DE HHC, ES SU BAJO REQUISITO DE POTENCIA.
