A gas turbine engine (10) includes a synchronizing ring (34). A cradle (78) includes an integrally formed anti-rotation feature (82). The cradle (78) is secured to the synchronizing ring (34) and located relative thereto with the anti-rotation feature (82)...

The method for the operation of a turbocompressor (11) entails increasing its RPM. During the RPM increase the position (VIGV) of a variable guide vane row (15) is altered and especially to close it in such a way that the compressor intake mass flow is res...

Four actuators are instructed to move to a condition indicated by a demand line 81. Their actual conditions are indicated by four arrows. The method determines if the range 84 of actual conditions exceeds a threshold value, representing an unacceptable mis...

The turbofan has a low pressure compressor (7) disposed axially between blades (10) of a front fan (3) and blades (14) of an aft fan (5). Stator grids (45, 46) are axially arranged on both sides of a movable vane crown (40). A grid gate ring (47) is suppor...

A method enables a variable vane assembly (44) for a gas turbine engine to be coupled to an engine casing (50). The variable vane assembly includes a bushing assembly (100) and at least one variable vane (52) that includes a platform (56) and a vane stem (...

In order to limit the flame temperature peaks following sudden load variations, corresponding control is planned of the position of the blades (13) of the distributor with variable geometry, of a single-shaft gas turbine (18); in particular, the control sy...

A gas turbine engine (10) comprises a first compressor (16), a combustor (22) and a first turbine (24) arranged in flow series. The first turbine (24) is arranged to drive the first compressor (16). The first compressor (16) has variable inlet guide vanes ...

In a gas turbine control apparatus, a frequency analyzing section (12) analyzes the frequency of at least one pressure oscillation in combustors of a gas turbine and the acceleration oscillation of each of the combustors and outputs a first frequency analy...

A variable inlet guide vane (30) includes opposite pressure and suction sides (34,36) extending along a chord between leading and trailing edges (40,42) and in span from root (44) to tip (46). The vane has a maximum thickness greater than about eight perce...
