GEARED TURBOFAN WITH HIGH FAN ROTOR POWER INTENSITY |
| 摘要 |
<p>A gas turbine engine includes a fan rotating structure including a plurality of fan blades supported on a hub that defines a frontal area. A turbine section drives the fan through a geared architecture about the axis. The fan rotating structure includes a weight of the fan rotating structure relative to the frontal area that enables improvements in engine operating and propulsive efficiencies.</p> |
