Proposed is a dynamometer for measuring load of a rotary shaft to be tested, the dynamometer comprising: a dynamometer shaft connected to the rotary shaft to be tested; a casing part having a through hole through which the dynamometer shaft passes, and a water supply chamber and a drain chamber therein; a stator part including a first stator and a second stator to be spaced apart from each other; a toroidal chamber partitioning part partitioning a toroidal chamber into a first toroidal chamber and a second toroidal chamber, wherein the toroidal chamber partitioning part comprises a runner and a guide ring, forming a drain slot through which the fluid is discharged from the first toroidal chamber and the second toroidal chamber to the drain chamber; and a flow adjusting part adjusting flow rate of the fluid.

Dynamometer with output control mechanism

A hydrodynamic-type hydraulic dynamometer is provided. The hydrodynamic-type hydraulic dynamometer includes a shaft rotatably mounted by a plurality of bearings, a stator fixed around the shaft and having a toroidal chamber therein, a runner rotatably coupled to the shaft and causing a fluid introduced into the toroidal chamber to flow therethrough, an inner ring mounted to extend inwardly from a radially outer side of the toroidal chamber and having a control slit formed therethrough, and a shutter configured to adjust an opening degree of the control slit.

Large-capacity hydrodynamic-type hydraulic dynamometer with output control mechanism

A turbine vane of a multi-stage arrangement of turbine vanes cooled by compressed air supplied from a compressor of a gas turbine has an improved structure capable of preventing an unintended removal of cooling holes along with the intended removal of an excess portion of a shroud. The turbine vane includes an airfoil configured to be installed on an inner peripheral surface of a turbine casing in which combustion gas supplied from a combustor flows and to guide combustion gas from a front-stage blade to a rear-stage blade; and a pair of shrouds coupled to the airfoil, at least one of the shrouds having a plurality of cooling holes formed toward the airfoil, wherein the plurality of cooling holes are formed along an imaginary line that is spaced apart from and surrounds the airfoil.
