Abstract: An improved slave propeller synchrophaser and mode logic for a multi-propeller aircraft is disclosed. A designated master propeller has at least one associated slave propeller which has its speed and phase controlled with respect to the master by initially controlling the speed of the slave propeller to within a selected constant number of RPM of the master so that the master and slave propellers are periodically in phase and then switching to phase control for controlling the speed of the slave propeller in the presence of a phase difference signal having an absolute magnitude less than a selected absolute magnitude. A selected phase difference relationship between the master and the slave may thus be effected with minimum transient effect on the speed of the slave propeller.

Abstract: A blade pitch angle control system for a wind turbine includes an improved control means (95) for providing a minimum pitch angle reference signal indicative of desired blade pitch at wind velocities less than rated. The control means includes means (35 and 30) for providing signals indicative of generated (output power or torque and the rotational frequency of the wind turbine rotor. The output and rotor speed signals are input to a function generator which, in rsponse to such signals, provides a signal indicative of the minimum pitch angle.

Abstract: SE DESCRIBE UN SINCRONIZADOR DE FASE PERFECCIONADO PARA HELICE ESCLAVA Y MODO LOGICO PARA UN AVION DE HELICES MULTIPLES. UNA HELICE DESIGNADA COMO PRINCIPAL TIENE POR LO MENOS UNA HELICE ESCLAVA ASOCIADA LA CUAL TIENE SU VELOCIDAD Y FASE CONTROLADA CON RESPECTO A LA PRINCIPAL, CONTROLANDO INICIALMENTE LA VELOCIDAD DE LA HELICE ESCLAVA DENTRO DE UN NUMERO CONSTANTE Y SELECCIONADO DE REVOLUCIONES POR MINUTO DE LA HELICE PRINCIPAL DE MANERA QUE LAS HELICES PRINCIPAL Y ESCLAVA SE ENCUENTRA PERIODICAMENTE EN FASE Y LUEGO SE CONMUTA EL CONTROL DE FASE PARA CONTROLAR LA VELOCIDAD DE FASE QUE TIENE UNA MAGNITUD ABSOLUTA INFERIOR A UNA MAGNITUD ABSOLUTA SELECCIONADA. UNA RELACION SELECCIONADA DE DIFERENCIA DE FASE ENTRE LA HELICE PRINCIPAL Y LA ESCLAVA PUEDE POR TANTO LLEVARSE A CABO CON UN MINIMO EFECTO DE TRANSICION EN LA VELOCIDAD DE LA HELICE ESCLAVA.
