Abstract

Une pale dhélice, une soufflante et une éolienne davion axial de faible charge caractérisées par le rapport daspect des pales faible; à proximité de lensemble des extrémités de pale, mais dans une distance appropriée, sont formées dans la pointe de chaque pale, qui sétend entre un côté pression et un côté aspiration, et un canal menant à lencoche formée à travers le corps de la pale entre les côtés. La distance entre lencoche et la pointe de la pale modifie le diamètre des pales de 1,2 % à 1,67 %, le long de la longueur de lencoche. Pendant lexploitation, lair sécoulant à travers cette ouverture élimine la turbulence formée à lextrémité des pales. Les vibrations en résonance survenant sur les pales et les éoliennes sont également réduites, ce qui étend la durée de vie des pales.
