摘要： A gas turbine engine blade (100) includes a blade portion (110) having a leading edge (202) and a trailing edge (204). A first surface (206) connects the leading edge (202) to the trailing edge (204) and a second surface (208) connects the leading edge (202) to the trailing edge (204). A tip section (200) is located at a first end of the blade portion (110) and includes a pocket (232) protruding into the tip section (200) from an outermost end of the tip section (200). The pocket (232) has a first side wall (236) adjacent the first surface (206) and a second side wall (238) adjacent the second surface (208). At least one of the first side wall (236) and the second side wall (238) have a curve distinct from a curve of the corresponding adjacent surface.

摘要： A method is provided for calibrating an active clearance control system (60) for a plurality of turbine engines (20). During this method, a squeeze test (500) is performed between a tip (66) of a rotor blade (68) and a shroud (64). Results of the squeeze test are applied to adjust a gap (62) between the tip and the shroud. The performance of the squeeze test and the application of the results are individually performed for each of the turbine engines. The active clearance control system includes an actuation system (70) and a controller (80) and is operable for recalibration based on the performance of another squeeze test.

摘要： The present invention is directed to an active clearance control (ACC) system for adjusting the clearance between an engine case (324) and a turbine section (330). The ACC control is based on the comparison of a clearance value, which is based on an operating state parameter and a passive clearance model, and a clearance target. If the deviation exceeds a threshold value, the active clearance control mechanism is activated, namley by activating a valve (312) for controlling the amount of cooling air which is supplied to the engine case (324) from the cooling air source (336). By adapting the cooling air flow to the engine case (324), its thermal expansion may be controlled actively and directly. By means of the above control, the gap between rotor and stator may be kept as small as possible while keeping the gap as small as possible.
