Definitions

  • the invention is available • to the aviation sector, but to the registered aerodynamic engines, they are not subject to any missions. 10
  • the basic task of the invention is to create an aerodynamic a materiel with an increased aerodynamic quality and a constant thickness of the appliance and the storage of its supporting equipment. 5
  • the task posed is solved by the fact that in an aerodynamic case with a fixed external contact, with upper L and lower] _.
  • it is more convenient than the simplest expression ⁇ / ⁇ , where X is the output of the input, the output of the input is obtained by imposing protection and classic protection, which is equivalent to

Abstract

Profil aérodynamique (2) à contour externe fixe dont les génératrices supérieure et inférieure présentent plus d'un extremum, lesdites génératrices étant formées par la superposition, étape par étape, de profils classiques (1, 4, 5), (1, 6, 7) décalés par corde, hauteur et angle d'incidence. Les contours au niveau de l'intersection des profils superposés sont interconnectés par des lignes d'ajustement et les extremums sur les génératrices supérieure et inférieure sont situés au niveau de la partie comprise entre 0 et 50 % de la corde.
