Abstract

ESTRUCTURA INTEGRADA DE LA COLA DE UN HELICOPTERO. LA ESTRUCTURA INTEGRADA DE LA COLA (20) INCLUYE UNA CARCASA (22) QUE ALOJA AL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18), UN ESTABILIZADOR VERTICAL (28) Y UN ESTABILIZADOR HORIZONTAL (30). LAS CONFIGURACIONES AERODINAMICAS Y/O ORIENTACIONES Y LAS ORIENTACIONES ESPACIALES DE LA CARCASA (22), DEL ESTABILIZADOR VERTICAL (28) Y DEL ESTABILIZADOR HORIZONTAL (30) ESTAN RELACIONADAS DE MANERA INTERACTIVA Y SE HAN MEJORADO PARA PROPORCIONAR LA ESTABILIDAD DE GUIÑADA, EL CONTROL DIRECCIONAL, LA ESTABILIDAD DE CABECEO Y LA MANIOBRABILIDAD REQUERIDAS EN LAS OPERACIONES DE VUELO DEL HELICOPTERO. LA CARCASA (22) ESTA ESPACIALMENTE ORIENTADA EN UN PRIMER ANGULO DE INCLINACION (U1) RESPECTO A LA SIMETRIA DEL PLANO VERTICAL (ZS) DEL FUSELAJE DEL HELICOPTERO (12) DE MODO QUE EL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18) PROPORCIONA UN EMPUJE ANTIPAR LATERAL PARA CONTRARRESTAR EL PAR INDUCIDO DEL EQUIPO ROTOR PRINCIPAL (14) Y UN COMPONENTE DE FUERZA VERTICAL POSITIVA PARA AUMENTAR LA CAPACIDAD DE ELEVACION TOTAL DEL HELICOPTERO. EL ESTABILIZADOR VERTICAL (28) ESTA ORIENTADO ESPACIALMENTE EN UN SEGUNDO ANGULO DE INCLINACION PREDETERMINADO (U2) RESPECTO AL PLANO VERTICAL (ZS) Y CONFIGURADO AERODINAMICAMENTE CON UNA INCLINACION PREDETERMINADA Y/O ORIENTADO AERODINAMICAMENTE CON UN ANGULO DE INCIDENCIA PREDETERMINADO PARA PROPORCIONAR UNA FUERZA ANTIPAR CUANDO SE VUELA HACIA ADELANTE LO QUE PERMITE QUE EL DISPOSITIVO ANTIPAR CON VENTILADOR ENTUBADO (18) SE DESCARGUE DE MANERA EFECTIVA Y ASI COMO UN COMPONENTE DE FUERZA VERTICAL NEGATIVA QUE COMPLEMENTA A LA FUERZA VERTICAL NEGATIVA PROPORCIONADA POR EL ESTABILIZADOR HORIZONTAL (30). EL FUNCIONAMIENTO AERODINAMICO DEL ESTABILIZADOR VERTICAL (28) PERMITE QUE LA CONFIGURACION AERODINAMICA Y/O LA ORIENTACION AERODINAMICA DEL ESTABILIZADOR HORIZONTAL (30) SE REDUZCAN Y FACILITA EL ACOPLAMIENTO DEL ESTABILIZADOR HORIZONTAL (30) EN RELACION SUSTANCIALMENTE SIMETRICA AL ESTABILIZADOR VERTICAL(28). EL ESTABILIZADOR HORIZONTAL (30) ESTA CONFIGURADO AERODINAMICAMENTE Y ORIENTADO DE TAL MODO QUE MEJORA LA ESTABILIDAD DE CABECEO DINAMICA DEL HELICOPTERO CUANDO VUELA HACIA ADELANTE.
