Abstract
An assembly is provided for an aircraft propulsion system. This assembly includes a center body, a scarfed inlet structure and an inlet passage. The scarfed inlet structure extends circumferentially about the center body. The inlet passage is radially between and formed by at least the center body and the scarfed inlet structure. A first component of the assembly is configured to rotate about an axis relative to a second component of the assembly between: (A) a first position where a metering portion of the inlet passage has a first area; and (B) a second position where the metering portion has a second area. The first component is one of the center body or the scarfed inlet structure, and the second component is the other one of the center body or the scarfed inlet structure.
Claims20
An assembly for an aircraft propulsion system, comprising:
- a double tapered center body;
- a nacelle inlet structure extending circumferentially around the double tapered center body;
- and
- an inlet passage radially between and formed by at least the double tapered center body and the nacelle inlet structure, the inlet passage comprising a metering portion;
- a first component of the assembly configured to rotate less than one-hundred and eighty degrees about an axis relative to a second component of the assembly between
- a first position where the metering portion has a first area;
- and
- a second position where the metering portion has a second area that is different than the first area;
- the first component of the assembly comprising one of the double tapered center body or the nacelle inlet structure;
- and
- the second component of the assembly comprising the other one of the double tapered center body or the nacelle inlet structure.
An assembly for an aircraft propulsion system, comprising:
- a center body including a first tapered surface, a second tapered surface and a plateau surface that extends axially between the first tapered surface and the second tapered surface;
- a nacelle inlet structure extending circumferentially around the center body;
- and
- an inlet passage radially between and formed by at least the center body and the nacelle inlet structure, the inlet passage comprising a metering portion;
- a first component of the assembly configured to rotate less than one-hundred and eighty degrees about an axis relative to a second component of the assembly between
- a first position where the metering portion has a first area;
- and
- a second position where the metering portion has a second area that is different than the first area;
- the first component of the assembly comprising one of the center body or the nacelle inlet structure;
- and
- the second component of the assembly comprising the other one of the center body or the nacelle inlet structure.
