CONT

The new rear-loaded aerofoils (Boeing dislikes the term super-critical) allow a thicker wing and reduced sweep angle, and while the long span has cost 1.5 per cent in weight, it has yielded five to six per cent in lift/drag ratio.

  • supercritical aerofoil

  • Constructions aéronautiques
CONT

Le nouveau profil à charge arrière (Boeing n'aime pas le mot "supercritique") permet d'obtenir une aile plus épaisse à flèche réduite. Si l'envergure plus longue a entraîné une augmentation de 1,5% de la masse de l'avion, elle a aussi permis d'en améliorer la finesse de 5 à 6%.

Key term(s)
  • profil supercritique
