Abstract

PERFILES AERODINAMICOS DE GEOMETRIA SENCILLA. LOS PERFILES AERODINAMICOS DE GEOMETRIA SENCILLA SE CARACTERIZAN PORQUE EN EL INTRADOS Y EN EL EXTRADOS, DESDE EL BORDE DE ATAQUE HASTA EL MAXIMO GROSOR DEL PERFIL, LA CURVA CORRESPONDE A UN CUADRANTE DE ELIPSE DE SEMIEJES "A" Y "B", QUE SE PROLONGARIA AGUAS ABAJO SEGUN UNA FUNCION Y=B.COS(X/A), HASTA EL BORDE DE SALIDA, MEDIANTE UN ENLACE CON IDENTICO RADIO DE CURVATURA Y BORDE DE SALIDA CON RADIO INFINITO Y CUERDA DE LONGITUD C=A.(1+PI/2), PERMITIENDO EL DISEÑO DE PERFILES ASIMETRICOS.
