VARIABLE GEOMETRY INLET SYSTEM |
| 摘要 |
A variable geometry inlet system of an aircraft engine includes an inlet duct. The inlet duct includes at least first and second sections moveable between extended and retracted positions such that the inlet duct defines a variable axial length of an inlet passage for selective flight conditions. The inclusion of acoustic treatment may assist in controlling noise. |

1. A variable geometry inlet system of an aeroengine comprising an inlet duct for directing an air flow from an opening in the inlet duct to a compressor, the inlet duct including at least first and second sections, the first and the second sections movable relative to one another between an extended position and a retracted position, the first and second sections in the extended position defining an axially longer inlet duct than when in the retracted position, the inlet duct extending continuously from the opening to the compressor in both positions and providing only one inlet path for the air flow from the opening to the compressor regardless of the inlet duct position. |
