Abstract
ALA QUE CONSTA DE VARIAS SECCIONES AERODINAMICAS (23,29,39,57,86,136,206) CADA UNA DE LAS CUALES SE CARACTERIZA POR TENER UN BORDE ANTERIOR DE GRAN RADIO, TENIENDO UNA CURVATURA UN APOGEO DE APROXIMADAMENTE EL 45% DE LA LONGITUD DE LA CUERDA DE LA SECCION AERODINAMICA Y UN BORDE POSTERIOR RELATIVAMENTE ROMO. LAS SECCIONES AERODINAMICAS DISMINUYEN LA RELACION DEL ESPESOR MAXIMO (H/B) A SU CUERDA DESDE ALREDEDOR DEL 20% CERCA DE LA BASE DEL ALA (20) HASTA ALREDEDOR DEL 2% CERCA DEL EXTREMO SUPERIOR DEL ALA. EL ESPESOR MAXIMO DE CADA SECCION AERODINAMICA SE INCREMENTA A LO LARGO DE LA LONGITUD DE LA CUERDA DESDE ALREDEDOR DEL 39% DE LA SECCION AERODINAMICA, EN UN 20% DE LA MISMA, HASTA ALREDEDOR DEL 42% DE LA LONGITUD DE LA CUERDA DE LA SECCION AERODINAMICA, EN UN 2% DE LA SECCION AERODINAMICA. ASI, EL ALA DEL INVENTO PROPORCIONA MEJOR COMPORTAMIENTO AERODINAMICO A LAS ALAS DE LA SERIE NACA 16 ENTRE 0,5 Y 0,7 MACH CON MENOR SUSCEPTIBILIDAD A SUFRIR DAÑOS POR OBJETOS EXTRAMOS YMEJORES POSIBILIDADES DE MANIPULACION.
