发明名称 APARELHO PARA MEDICAO DE FASE ENTRE UMA HELICE PRINCIPAL E UMA HELICE DE OPERACAO CONTINUA EM UMA AERONAVE
摘要 A method and apparatus for providing improved phase error measurement as shown and described. The measured phase error is used as an input to a SYNCHROPHASER TM which provides for sphase control of a slave propeller with respect to a master. The phase error ( phi E) is the sum of the sensed phase error and 360 DEG divided by Np times phi COUNT minus phi REF. phi COUNT is a counted number of phase discontinuities which occur in phi S, the sensed phase. The values of phi COUNT and phi E, measured phase output, may be limited in number and magnitude.
