Abstract

LA REFERENCIA DE VELOCIDAD DEL MOTOR DE UN HELICOPTERO (66) SE AUMENTA (117, 118) EN RESPUESTA A LA CARGA PESADA DEL ROTOR (102) QUE SOBREPASA UN VALOR MINIMO A LA VELOCIDAD ASCENDENTE EN ESE MOMENTO (4). LA VELOCIDAD DE REFERENCIA AUMENTA GRADUALMENTE (117, 118) A RAPIDA VELOCIDAD HASTA UN 107% MAS QUE LA VELOCIDAD NOMINAL (119). TRAS UN INTERVALO DE TIEMPO FIJO (129), LA CARGA REDUCIDA DEL ROTOR (122), EL ANGULO DE CABECEO REDUCIDO POR DEBAJO DE UNA MAGNITUD MINIMA (121) Y EL ANGULO DE BALANCEO REDUCIDO POR DEBAJO DE UNA MAGNITUD MINIMA (120) HARAN QUE LA VELOCIDAD DE REFERENCIA DESCIENDA LENTAMENTE (146, 147) A LA VELOCIDAD NOMINAL (148). EL AUMENTO AUTOMATICO DE LA VELOCIDAD DE REFERENCIA DEL MOTOR SOBREPASA UN 107% LA VELOCIDAD NOMINAL (203) CUANDO SE ACTIVA UN CONMUTADOR DE BATALLA (201) Y EL ARMAMENTO SE ENCUENTRA PREPARADO (202). EL AUMENTO DE LA VELOCIDAD DE REFERENCIA DEL MOTOR ESTA PROHIBIDA (207) CUANDO EL HELICOPTERO FUNCIONA EN UN MODO SILENCIOSO (206) O CUANDO EL HELICOPTERODESCANSA SOBRE LAS RUEDAS (208).
