TRANSLATING GASPATH BLEED VALVE |
| 摘要 |
A bleed of valve comprises a ring axially translatable between a retracted position in which the ring is configured to close an annular bleed off opening defined in a converging portion of a radially outer annular wall of a gas turbine engine gaspath and a deployed position in which the ring protrudes into the gaspath to mechanically scoop out incoming air and water/hail particles. |

1. A bleed off valve (BOV) for a gas turbine engine having a gaspath bounded by a radially outer annular wall extending about an axis of the gas turbine engine, the radially outer annular wall having a converging portion; the BOV comprising:
a ring axially translatable between a retracted position in which the ring is configured to close an annular bleed off opening defined in the converging portion of the radially outer annular wall and a deployed position in which the ring is configured to protrude into the gaspath; and an actuator operatively connected to the ring to axially translate the ring between the retracted and deployed positions. |
