Abstract
A propulsor system comprising a propulsor and an exhaust area control mechanism are described. The exhaust area control mechanism is connected to an outlet of the propulsor and is configured to vary the area through which air exits the propulsor system.
Claims10
An exhaust control system comprising:
- a tail cone configured to be directly connected to a stator of a propulsor fan, the tail cone including:
- a first end of the tail cone having a plurality of concentric rings including a first ring and a second ring, the first ring including a first end that is configured to connect to the stator of the propulsor fan and a second end that is opposite the first end of the first ring, and the second ring including a first end that overlaps the second end of the first ring such that the second end of the first ring is inserted into the first end of the second ring and a second end of the second ring;
- a second end of the tail cone that is opposite the first end;
- and
- an intermediate portion having an end and the second end of the second ring is inserted into the end of the intermediate portion, and the intermediate portion is disposed between the second end of the second ring and the second end of the tail cone, the intermediate portion having a diameter that is greater than a diameter of the first end of the tail cone and a diameter of the second end of the tail cone;
- and
- an exhaust area control mechanism configured to adjust an amount of overlap between the second end of the first ring and the first end of the second ring of the tail cone and adjust an amount of overlap between the second end of the second ring and the intermediate portion of the tail cone to adjust a length of the tail cone such that a position of the intermediate portion within an outlet of the propulsor fan changes thereby varying an area of the outlet of the propulsor fan.
