Abstract

DISPOSITIVO ANTIPAR DE UN HELICOPTERO. UN DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18) PARA UN HELICOPTERO QUE TIENE UNA ESTRUCTURA DE COLA (20) QUE INCLUYE UNA CARCASA (22) CONFIGURADA PARA EL MONTAJE INTERNO DEL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18). EL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18) TIENE UNA CONFIGURACION MEJORADA PARA PROPORCIONAR EL EMPUJE ANTIPAR REQUERIDO PARA LA ESTABILIDAD DE GUIÑADA Y LA MANIOBRABILIDAD DEL HELICOPTERO Y PARA REDUCIR LOS NIVELES DE RUIDO ORIGINADOS POR EL FUNCIONAMIENTO DEL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18). EL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18) INCLUYE UN CONDUCTO PARA LA CORRIENTE DE AIRE (40) Y UN VENTILADOR (60) MONTADO COAXIALMENTE DENTRO DEL CONDUCTO PARA LA CORRIENTE DE AIRE (40). EL CONDUCTO PARA LA CORRIENTE DE AIRE (40) INCLUYE UNA ENTRADA (46) QUE TIENE UNA TAPA CURVA DE RADIO CONSTANTE, UNA PORCION DE CONDUCTO DIVERGENTE (48) CORRIENTE ABAJO RESPECTO A LA ENTRADA (46) Y CONTINGUA A ELLA QUETIENE UN ANGULO DE DIVERGENCIA PREDETERMINADO (U) Y UNA SALIDA (50) QUE TERMINA LA PORCION DEL CONDUCTO DIVERGENTE QUE TIENE UNA CONFIGURACION DE TAPA CURVA DE RADIO VARIABLE. EL VENTILADOR INCLUYE UNA ESTRUCTURA DE CABEZA CENTRAL (62), UNA PLURALIDAD DE PUNTALES DE SOPORTE (64) PARA MONTAR COAXIALMENTE LA ESTRUCTURA DE CABEZA (62) EN EL CONDUCTOR PARA LA CORRIENTE DE AIRE (40) Y UN SUBSISTEMA DE ROTOR DE COLA MONTADO DE MANERA ROTATIVA EN LA ESTRUCTURA DE CABEZA (62). LOS PUNTALES DE SOPORTE (64) TIENEN UNA CONFIGURACION ELIPTICA PARA MEJORAR EL RENDIMIENTO AERODINAMICO Y REDUCIR EL RUIDO GENERADO POR EL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18). UNO (64A) DE LOS PUNTALES DE SOPORTE (64) SE ENCUENTRA RADIALMENTE ORIENTADO Y OTROS DOS PUNTALES (64B) NO ESTAN ORIENTADOS RADIALMENTE RESPECTO AL EJE DEL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18). EL SUBSISTEMA DE ROTOR DE COLA ES UN ROTOR RIGIDO QUE TIENE OCHO PALAS (66). LOS PUNTALES DE SOPORTE (64) ESTAN SEPARADOS DEL PLANO DELAS PALAS DEL ROTOR (66) UNA DISTANCIA PREDETERMINADA BASADA EN UNA DIMENSION AXIL DE LA CONFIGURACION ELIPTICA DE LOS PUNTALES DE SOPORTE (64).
