Abstract

APARATO PARA CONTROLAR EL PASO DE LAS PALAS DE UNA HELICE AEREA, DE PASO VARIABLE, GOBERNADA POR REGULADOR.EL APARATO TIENE POR OBJETO ADAPTAR EL PAR TRANSMITIDO POR UN ORGANO MOTOR AL CONSUMIDO POR LA HELICE. SE CARACTERIZA POR DISPONER DE MEDIOS DE RETENCION DE LAS PALAS EN UN ANGULO DE PASO QUE GENERA EMPUJE, MAYOR QUE EL LIMITE DE PASO PEQUEÑO, DURANTE UN PERIODO EN QUE EL ORGANO MOTOR ESTA TRANSMITIENDO UN PAR QUE, EN OTRO CASO, SERIA INSUFICIENTE PARA MOVER LA PALA SEPARANDOLA DEL ANGULO CORRESPONDIENTE AL LIMITE DE PASO PEQUEÑO, DE MODO QUE, CON EL ORGANO DEL MOTOR AL RALENTI, LA HELICE GIRE MAS LENTAMENTE, AL TIEMPO QUE PROPORCIONA EMPUJE UTIL.
