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.AERODYNAMIC PROFILES OF SIMPLE GEOMETRY. THE AERODYNAMIC PROFILES OF SIMPLE GEOMETRY ARE CHARACTERIZED BECAUSE IN THE INTRATES AND IN THE EXTRATES, FROM THE ATTACK EDGE TO THE MAXIMUM THICKNESS OF THE PROFILE, THE CURVE CORRESPONDS TO A QUADRANT OF ELIPSE OF SEMI-SEXES "TO" AND " DOWNWATER ACCORDING TO A FUNCTION Y = B.COS (X / A), TO THE OUTPUT EDGE, THROUGH A LINK WITH THE IDENTIFIC RADIUS OF CURVATURE AND OUTPUT EDGE WITH INFINITE RADIUS AND ROPE OF LENGTH C = A. (1 + PI / 2), ALLOWING THE DESIGN OF ASYMMETRIC PROFILES.
