Patent number: 8104261Abstract: A gas turbine engine system includes a fan (14), a housing (28) arranged about the fan, a gas turbine engine core having a compressor (16) at least partially within the housing, and a fan bypass passage (30) downstream of the fan for conveying a bypass airflow (D) between the housing and the gas turbine engine core. A nozzle (40) associated with the fan bypass passage includes a first nozzle section (54a) that is operative to move in a generally axial direction to influence the bypass airflow, and a second nozzle section that is operative to also move in a generally axial direction between a stowed position and a thrust reverse position that diverts the bypass airflow in a thrust reversing direction. An actuator (42) selectively moves the first nozzle section and the second nozzle section to influence the bypass airflow and provide thrust reversal.Type: GrantFiled: October 12, 2006Date of Patent: January 31, 2012Assignee: United Technologies CorporationInventors: Richard M. Marshall, Robert L. Gukeisen

Publication number: 20090266912Abstract: A fan variable area nozzle (FVAN) includes a flap assembly which varies a fan nozzle exit area. An actuator system drives a sliding drive ring relative a multitude of slider tracks mounted to a fan nacelle to adjust each flap of the flap assembly through the flap linkage to pitch the flap assembly about a circumferential hinge line to vary the diameter of the annular fan nozzle exit area between the fan nacelle and the core nacelle. The FVAN may be separated into a multiple of drive ring sectors which are each independently adjustable by an associated actuator of the actuator system to provide a low profile drag asymmetrical fan nozzle exit area.Type: ApplicationFiled: October 12, 2006Publication date: October 29, 2009Inventor: Robert L.

Patent number: 6048171Abstract: The invention is a valve system particularly useful as a bleed valve system in a gas turbine engine. The valve system includes a valve ring or partition (44) that bounds a plenum (52). The valve ring has a set of two or more fluid flow regulating apertures (46), and one or more chains (60L, 60R) of metering plates (56). Each metering plate is pivotably supported relative to one of the apertures (46) to regulate fluid flow through the aperture. A coupling system that includes a series of transfer links (76) extending between neighboring metering plates successively conveys pivotal motion and angular orientation from each metering plate to the successive metering plate in the chain. An actuation system (90) includes a drive system (94) responsive to an actuator (92) for governing the angular orientation of the metering plates.Type: GrantFiled: September 9, 1997Date of Patent: April 11, 2000Assignee: United Technologies CorporationInventors: Brian G.
