Abstract

LA INVENCION ESTA RELACIONADA CON UNA ESTRUCTURA DE EMPENAJE VERTICAL PARA UN AVION. SE UTILIZA PRINCIPALMENTE PARA LA ASPIRACION CONTROLADA DE LA CAPA LIMITE PERTURBADA DEL EMPENAJE VERTICAL, CON OBJETO DE ESTABILIZAR LA CORRIENTE LAMINAR Y/O EVITAR EL DESPRENDIMIENTO DE LA CORRIENTE. LA PROTECCION ANTIENGELAMIENTO DEL BORDE DE ATAQUE DEL EMPENAJE VERTICAL PUEDE ACTIVARSE. MEDIANTE LAS MEDIDAS ADECUADAS SE OBTIENE UNA CORRIENTE SUPERFICIAL LAMINAR EN EL EMPENAJE VERTICAL, QUE PERMITE REDUCIR LA RESISTENCIA DEL AIRE DEL AVION Y EL CONSUMO DE COMBUSTIBLE Y AUMENTAR NOTABLEMENTE LA RENTABILIDAD DE UN AVION DE PASAJE. LA ESTRUCTURA DEL EMPENAJE VERTICAL SE COMPONE DE UNA ESTRUCTURA DE SOPORTE DEL EMPENAJE Y DEL CORRESPONDIENTE BORDE DE ATAQUE MONTADO EN LA PARTE FRONTAL. ESTE PRESENTA UN BORDE PERFILADO CURVADO HACIA EL INTERIOR, DE APROXIMACION PARABOLICA Y PERFORADO, Y ESTA DIVIDIDO POR CAMARAS DISPUESTAS HORIZONTALMENTE. EN EL BORDE PERFILADO DEL BORDE DE ATAQUE HAY UN ELEMENTO PLANO PERFORADO SOBRE EL QUE SE HA MONTADO UNA CAPA PERFORADA, ENCIMA DE LA CUAL TIENE LUGAR LA ABSORCION DE LA CAPA LIMITE. CADA CAMARA ESTA CONECTADA CON UNA TUBERIA. LAS TUBERIAS LLEVAN UNA UNIDAD DE CONTROL DE VALVULAS QUE CONTIENE VARIAS VALVULAS REGULADORAS DE ASPIRACION DE AIRE. LA UNIDAD DE CONTROL DE VALVULAS ESTA CONECTADA ASIMISMO CON UN DISPOSITIVO DE CONTROL QUE ACTIVA INDEPENDIENTEMENTE LAS VALVULAS REGULADORAS DE ASPIRACION DE AIRE EN BASE A LAS SEÑALES DE SENSORES RECIBIDAS. LAS TUBERIAS DESEMBOCAN EN UN DEPOSITO DE AIRE, CONECTADO A UNA UNIDAD COMPRESORA QUE PERMITE GENERAR UN VACIO PARA LA ABSORCION. UN PUENTE DE TUBERIAS CONECTA AMBOS ELEMENTOS, Y UNA TUBERIA DE SALIDA CONECTADA DESPUES DE LA UNIDAD COMPRESORA ESTA CONECTADA CON UNA SALIDA DE AIRE UBICADA EN EL FUSELAJE. EL PUENTE DE TUBERIAS LLEVA UNA INTERSECCION DE VALVULAS DE TUBERIAS SITUADA ANTES Y/O DESPUES DE LA UNIDAD COMPRESORA. DEL PUENTE DE TUBERIAS DIVERGE UNA TUBERIA DE CONEXION DE DESVIACION, CON UNA INTERSECCION DE VALVULAS DE DESVIACION REGULABLE QUE PERMITE LA ENTRADA CONTROLADA DE AIRE EXTERIOR.
