PROTECTING CAP FOR THE LEADING EDGE OF A TURBO FAN BLADE |
| 摘要 |
<p>A fairing formed from a dihedron of which the faces, disposed in the extension of the intrados and extrados surfaces follow the aerodynamic profile of the blade. Such rejoin the blade at a small radius portion constituting a leading edge. The fairing imparts a characteristic enabling the optimum efficiency of the fan to be approached. The useful height of the dihedron is at least 5% of the height of the blade.</p> |
