Abstract
SE DESCRIBE UN PROCEDIMIENTO Y APARATO PARA LIMITAR LOS MOVIMIENTOS TRANSITORIOS ENTRE UN MIEMBRO DE POTENCIA DE AERONAVE Y LA ESTRUCTURA DE LA MISMA. EL APARATO INCORPORA UN ACOPLADOR (20) PARA USAR CON MONTAJES TIPO INERCIAL, E INCLUYE UNA PORCION DE CUERPO (21) CON UN PISTON ACOPLADOR (32) INTRODUCIDO TELESCOPICAMENTE EN EL MISMO. CUANDO SE SUPERA UN MOVIMIENTO RELATIVO TRANSITORIO QUE HACE QUE SE SUPERE UNA DETERMINADA VELOCIDAD DE FLUJO DE FLUIDO, EL ASIENTO (38) DISPUESTO EN EL PISTON ACOPLADOR (32) INTERACCIONA CON EL LABIO (39) DE LA PORCION DEL CUERPO (21), PARA PROVOCAR UNA RESTRICCION DEL FLUJO DE FLUIDO. ESTE PROCEDIMIENTO Y APARATO RESTRINGEN Y LIMITAN LOS MOVIMIENTOS TRANSITORIOS, ES DECIR, ACTUAN COMO AMORTIGUADORES, PARA LIMITAR EL MOVIMIENTO RELATIVO POSTERIOR ENTRE UN MIEMBRO DE POTENCIA (54) DE LA AERONAVE Y UN MIEMBRO ESTRUCTURAL (52) DE LA MISMA. EL PISTON ACOPLADOR (32) INCLUYE PREFERENTEMENTE UN CIERRE FLEXIBLE (30) FORMADO EN EL MISMO, Y UN ORIFICIO (40) QUE PASA POREL, A FIN DE PROPORCIONAR UNA AMORTIGUACION DEL TIPO DE ESTRANGULAMIENTO AL REALIZAR LA AMORTIGUACION. ESTE PROCEDIMIENTO Y APARATO SON PARTICULARMENTE UTILES EN LOS MONTAJES DE FLUIDO TIPO INERCIAL PARA MONTAR EN MOTORES DE AERONAVE, LOS AISLADORES DE PILONES FLUIDOS PARA AISLAMIENTO DEL PILON DE UN HELICOPTERO Y LOS SISTEMAS FTR (LIMITACION DEL PAR DE FLUIDO) PARA AERONAVES, A FIN DE LIMITAR MOVIMIENTOS TRANSITORIOS EN CIERTAS CONDICIONES, POR EJEMPLO, DURANTE EL DESPEGUE, EL ATERRIZAJE Y OTRAS MANIOBRAS, AL MISMO TIEMPO QUE PROPORCIONAN AISLAMIENTO EN CONDICIONES NORMALES DE FUNCIONAMIENTO.
