Filed:

Dec 9, 2009

Appl. No.:

12/634606

Inventors:

Gregory W. P. Zeaton - Indianapolis IN, US
David L. Sutterfield - Greenwood IN, US
Sean F. Sullivan - Tremonton UT, US

International Classification:

F02C 7/20

US Classification:

60796

Abstract:

A gas turbine engine adapter is provided. In one form the adapter is segmented and may be attached to a gas turbine engine support ring. The adapter can provide a channel that may receive part of a gas turbine engine component such as, but not limited to, a plug nozzle. The adapter can include a load bearing support to counteract axial forces experienced by the plug nozzle during operation of the gas turbine engine. A compressible seal can be provided between the plug nozzle and the adapter. A leaf seal can also be provided to seal between segments of the adapter. The plug nozzle can be discouraged from rotating relative to the adapter.

Appl. No.:

12/974995

Inventors:

David Levi Sutterfield - Greenwood IN, US

International Classification:

F02K 3/02

US Classification:

60204, 602263

Abstract:

A gas turbine engine is provided having an offtake passage that in one form is capable of extracting a bypass flow from the engine. The airflow traversing the offtake passage is introduced to an exhaust flow of the gas turbine engine through an offtake outlet. The offtake outlet includes an airflow member that is moveable. A nozzle is also provided for exhaust from the gas turbine engine. In one form the nozzle includes moveable duct members. Flows exiting the offtake outlet and the nozzle can be combined after passing the airflow member and the moveable duct members, respectively.

International Classification:

B64C 2900

US Classification:

244 23A, 244 23 D, 244 124

Abstract:

A thrust vectoring mechanism to vector thrust and control discharge throat area includes four or more vanes mounted across the outlet of a nozzle in a cascade arrangement. The mechanism further includes a rod to control pivoting of each of the vanes that may be selectively rotated with one or more actuators. The rod includes threading. The vanes each include a drive member that is either toothed to engage the rod threading or defines a camming relationship with a coupling member threaded on the rod. The rod threading, drive members, and coupling members may be arranged to define different pivoting schedules for each of the vanes so that a generally constant throat area may be maintained over a given vector directional range of the vanes. The outlet may be generally rectangular in cross-section and a strut may be mounted across the outlet perpendicular to the pivot axes of the vanes to house the rod, drive members, and/or coupling members.

International Classification:

F01D 17/16
F02K 1/08

Abstract:

A variable exhaust nozzle for use with a gas turbine engine includes an outer shroud and an inner plug that can move relative to the outer shroud. The relative movement of the inner plug and the outer shroud changes the shape of the variable exhaust nozzle from one that converges in area to one that converges and then diverges in area.

Inventors:

- Indianapolis IN, US
David L. Sutterfield - Greenwood IN, US
Bryan H. Lerg - Carmel IN, US

International Classification:

F02K 1/08

Abstract:

A variable exhaust nozzle for a gas turbine engine includes an outer shroud and an inner plug. The outer shroud is arranged circumferentially about an axis. The inner plug extends along the axis and is at least partially located within the outer shroud. At least one of the outer shroud and the inner plug are movable selectively to cause a variable area region of the variable exhaust nozzle to change.
