Abstract
A convergent flap roller assembly is provided that includes a first hanger flange, a second hanger flange, a roller, and a pivot axle. Each hanger flange has a panel, a roller shaft, and at least one track tab. Each roller shaft extends outwardly from the respective panel, and includes a roller shaft bore. The roller has a center bore and an exterior contact surface. The roller shafts are received within the roller center bore and are in contact with each other, and the pivot axle extends through the roller shaft bores.
Claims13
A convergent flap roller assembly, comprising:
- a first hanger flange having a first panel, a first roller shaft, and at least one first track tab, wherein the first roller shaft extends outwardly from the first panel, and includes a first roller shaft bore;
- a second hanger flange having a second panel, a second roller shaft, and at least one second track tab, wherein the second roller shaft extends outwardly from the second panel, and includes a second roller shaft bore;
- a roller having a center bore and an exterior contact surface;
- and
- a pivot axle;
- wherein the first roller shaft and the second roller shaft are received within the roller center bore and are in contact with each other, and the pivot axle extends through the first roller shaft bore and the second roller shaft bore;
- wherein the first panel includes a first inner surface and an opposing first outer surface, and the first roller shaft extends outwardly from the first inner surface, and the at least one first track tab extends outwardly from the first inner surface;
- and
- wherein the second panel includes a second inner surface and an opposing second outer surface, and the second roller shaft extends outwardly from the second inner surface, and the at least one second track tab extends outwardly from the second inner surface.
A convergent-divergent nozzle, comprising:
- a plurality of divergent flaps, each with a forward end and an aft end;
- a plurality of convergent flaps, each with a forward end, an aft end, and at least one support flange, wherein each respective convergent flap is pivotally attached to a respective one of the plurality of divergent flaps;
- wherein a roller assembly engages each convergent flap with a guide track, and each roller assembly includes:
- a first hanger flange having a first panel, a first roller shaft, and at least one first track tab, wherein the first roller shaft extends outwardly from the first panel, and includes a first roller shaft bore;
- a second hanger flange having a second panel, a second roller shaft, and at least one second track tab, wherein the second roller shaft extends outwardly from the second panel, and includes a second roller shaft bore;
- a roller having a center bore and an exterior contact surface;
- and
- a pivot axle;
- wherein the first roller shaft and the second roller shaft are received within the roller center bore and are in contact with each other, and the pivot axle extends through the first roller shaft bore and the second roller shaft bore;
- wherein the at least one support flange of each convergent flap includes a first support flange and a second support flange;
- wherein the first roller shaft of the first hanger flange extends through the first support flange, and the second roller shaft of the second hanger flange extends through the second support flange;
- and
- wherein the roller is disposed between the first support flange and the second support flange.
