Le soufflage n'est déclenché que lorsque les volets sont abaissés et permet de réduire la couche limite, ce qui a pour effet d'augmenter la portance. Surtout utilisé dans les années 1960, ce système a été plus ou moins abandonné depuis à cause de sa complexité et sa maintenance difficile. Parmi les avions l'ayant mis en œuvre, on peut citer par exemple le F-104 Starfighter ou le Blackburn Buccaneer. 3, record 2, French, - volet%20souffl%C3%A9

[…] le procédé de séparation UCOR par vortex […] est de type aérodynamique et peut être qualifié de «procédé de centrifugation à paroi fixe»[.] […] un mélange gazeux est injecté dans un tube de révolution suivant une direction non radiale, de façon à y pénétrer avec une forte composante de vitesse tangentielle, ce qui induit la rotation du gaz dans le tube, d’où une force centrifuge et un effet séparatif. L’efficacité de la séparation est d’autant meilleure que la rotation du gaz est rapide, ce qui nécessite l’utilisation d’un gaz porteur léger lorsque la séparation concerne des isotopes lourds. 1, record 3, French, - proc%C3%A9d%C3%A9%20de%20s%C3%A9paration%20UCOR%20par%20vortex

Les profils aérodynamiques ont des formes qui permettent d'obtenir des rendements élevés. Les éoliennes à portance utilisent ce type de profil : il est évident que l'inconvénient de ce type d'éolienne est leur plus grande difficulté de réalisation. 2, record 5, French, - capteur%20%C3%A0%20portance

Rotor Aerodynamic devices... The "dinotail" is [a device] in which a serrated trailing edge-similar to the back tail plates of a stegosaurus, hence dino(saur) tail, was tried out to modify vortex shedding and reduce acoustic emissions. It was found to reduce drag generally and hence improve power performance. 2, record 6, English, - dinotail
