BOUNDARY LAYER INGESTING BLADE |
| 摘要 |
A boundary layer ingesting (BLI) blade having a span is provided and includes a root section connectable to a hub, a tip section disposable at a distance from the hub and having a pitch and a body extending in a spanwise dimension from the root section to the tip section. The root section has a local pitch from the root section to about a 70% span location, which is less than the pitch at the tip section, to thereby reduce local angles of attack in a boundary layer region defined in and around the root section. |

1. A boundary layer ingesting (BLI) blade having a span, comprising:
a root section connectable to a hub; a tip section disposable at a distance from the hub and having a twist; and a body extending in a spanwise dimension from the root section to the tip section, the root section having a local twist from the root section to about a 70% span location, which is greater than the twist at the tip section, to thereby adjust local angles of attack in a boundary layer region defined in and around the root section. |
