    摘要: An aircraft gas turbine engine (7) axisymmetric vectoring nozzle has an interface ring centered about a nozzle centerline (8), a vectoring ring (86) disposed radially inwardly of and apart from the interface ring (20), and a bearing (22) radially disposed between the vectoring ring (86) and the interface ring (20). The bearing (22) may be a sliding bearing having a sliding interface between the vectoring ring (86) and the interface ring (20) and the sliding interface is spherical in shape. The bearing (22) may be constructed of sliding bearing segments having sliding interfaces between the vectoring ring (86) and the interface ring (20) and the sliding interfaces (24) are spherical in shape. Each of the bearing segments (26) includes an outer sliding element (28) attached to the interface ring (20), an inner sliding element (30) attached to the vectoring ring (86), and spherically curved outer and inner sliding surfaces (32, 36) on the outer and inner sliding elements (28, 30) respectively wherein the spherically curved outer and inner sliding surfaces (32, 36) define the sliding interfaces (24) between the vectoring ring (86) and the interface ring (20). At least one of the outer sliding elements (28) is circumferentially disposed and trapped between circumferentially spaced apart rails (38) disposed on a corresponding one of the inner sliding elements (30). A plurality of interface ring support guides are disposed radially inwardly of and in sliding support relationship with the interface ring (20) and located axially forward of the vectoring ring (86).

    摘要: A system for enabling an aircraft (10) to accomplish extremely short takeoffs and landings, which includes an integrated flight control system (20); a takeoff system; a landing system and a high thrust-to-weight propulsion system (21). The integrated flight propulsion control system (20) includes a multi-axis thrust vectoring system (21). The takeoff system is operably engageable with the multi-axis thrust vectoring system (21). The takeoff system includes means (22) for rotating the aircraft nose upwardly below stall speed without substantial use of thrust vectoring from the multi-axis thrust vectoring system. The landing system (16,18) is operably engageable with the multi-axis thrust vectoring system (21). It includes means (22) for de-rotating the aircraft (10) from a high angle of attack to a main gear (18) touchdown angle of attack sufficiently low to avoid scraping the tail of the aircraft. The high thrust-to-weight propulsion system (21) is connected to the integrated flight propulsion control system for providing sufficient lift to support the aircraft (10) at speeds below stall speed.

    摘要: Die Erfindung bezieht sich auf einen Strömungkanal von kurzer Baulänge. Ein derartiger Strömungskanal soll eine Verzweigung des Gasstromes ermöglichen, so daß beispielsweise die Brennkammern von Turbinen versorgt oder eine vor Niederschlägen geschützte Dachentlüftung vorgenommen werden können. Der Gasstrom gelangt dabei über einen Eintrittskanal (7) nach Aufteilung mittels eines Trennkeils in zwei Verzweigungskanäle (12). Ein derartiger Strömungskanal wird strömungstechnisch umso verlustreicher, je kürzer er ausgeführt wird. In diesem Fall lassen sich die Verluste weitgehend vermeiden, wenn die Verzweigungskanäle (1, 2) erfindungsgemäss sich zunächst zunehmend bis zu ihrer Umlenkung (3, 4) einschnüren. Im Bereich ihrer Umlenkung (3, 4) sind Leitschaufeln (5, 6) vorgesehen, und im Anschluß an die Umlenkung (3, 4) erfahren die Verzweigungskanäle (1, 2) wiederum eine stetige Erweiterung. Die Leitschaufeln (5, 6) sind verschwenkbar gelagert, so daß sie auch zur Absperrung der Verzweigungskanäle (1,2) verwendet werden können.

    摘要: A fluid vectoring nozzle (10) comprises flow vectoring means suitable for selectively producing a fluid dynamic throat (28) in the nozzle(1 0) in a plane oblique to the axis of the nozzle (10), such that in operation fluid flow passing through the throat (28) is rotated about an axis parallel to and coincident with the plane of the throat (28). That is to say, the present invention comprises flow vectoring means suitable for selectively producing a fluid dynamic throat (28) in the nozzle (10) in a plane oblique to the axis of the nozzle (10), such that, in operation, fluid passing through the fluid dynamic throat (28) is turned towards an angle perpendicular to the plane of the throat (28). Fluid injection means are provided to inject a control fluid (26) into the nozzle (10) through a perforate region provided in at least one nozzle wall (23), thereby generating a fluid dynamic restriction (24) which initates the formation of the fluid dynamic throat (28).
