Abstract
An assembly is provided for an aircraft propulsion system. This assembly includes a variable area inlet, and the variable area inlet includes an inlet structure, an inlet lip, an inlet orifice and an inlet passage extending within the variable area inlet from the inlet orifice. The inlet lip is configured to pivot about a pivot axis between a first position and a second position. The inlet orifice is formed by and between the inlet structure and the inlet lip. The inlet orifice has a first area when the inlet lip is in the first position. The inlet orifice has a second area when the inlet lip is in the second position. The second area is different than the first area.
Claims20
An assembly for an aircraft propulsion system, comprising:
- a variable area inlet including an inlet structure, an inlet lip, an inlet orifice and an inlet passage extending within the variable area inlet from the inlet orifice;
- the inlet lip configured to pivot about a pivot axis between a first position and a second position;
- and
- the inlet orifice formed by and between a portion of the inlet structure and a portion of the inlet lip, the inlet orifice having a first area when the inlet lip is in the first position, the inlet orifice having a second area when the inlet lip is in the second position, the second area different than the first area, and the pivot axis laterally offset from the portion of the inlet lip when the inlet lip is in the first position and the second position.
An assembly for an aircraft propulsion system, comprising:
- a gas turbine engine comprising a bypass flowpath and a core flowpath;
- and
- a variable area inlet configured to direct air into the bypass flowpath and the core flowpath, the variable area inlet including an inlet structure, an inlet lip, an inlet orifice and an inlet passage extending within the variable area inlet from the inlet orifice;
- the inlet lip configured to pivot about a pivot axis between a first position and a second position;
- and
- the inlet orifice formed by and between the inlet structure and the inlet lip, the inlet orifice having a first area when the inlet lip is in the first position, the inlet orifice having a second area when the inlet lip is in the second position, and the second area different than the first area.
An assembly for an aircraft propulsion system, comprising:
- a variable area inlet including an inlet structure, an inlet lip, an inlet orifice and an inlet passage extending within the variable area inlet from the inlet orifice;
- the inlet lip configured to pivot about a pivot axis between an open position and a closed position;
- and
- the inlet orifice formed by and laterally between a portion of the inlet structure and a portion of the inlet lip, the inlet orifice having a first area when the inlet lip is in the open position, the inlet orifice having a second area when the inlet lip is in the closed position, the second area less than the first area, and the pivot axis disposed laterally between the portion of the inlet structure and the portion of the inlet lip when the inlet lip is in the open position and the closed position.
