Abstract:
The present invention concerning of a device for mounting or dismantling, replacement and maintenance of a can-combustor of a gas turbine engine including an assembly tool or assembly tool with additional frame having at least one lifting beam, at least one linear driver, wheels, at least one eccentric rolling hook for fixation of the gas turbine housing, optionally spacers for building the interface to the can-combustor, adapters, lifting points for the main crane. The eccentric rolling hook is connected to the gas turbine housing by giving in axial or quasi-axial direction a force for mounting or dismantling the can-combustor from the gas turbine housing.
Abstract:
The present invention concerns of an apparatus as a part of an assembly tool or an assembly tool with additional frame for mounting or dismantling, replacement and maintenance of a component of an engine. The apparatus includes an eccentric hook having means to adjust, discretely or operatively communicating with a crane or an independently operated assembly tool. The position of the component operates in radial or quasi-radial position with respect to the engine housing, whereas the eccentric hook comprising an outer structure/casing, an inner ring, a cut out with an eccentric disposition, whereas the eccentric hook is self-locking or semi-self-locking with respect to a counterpart attached to the engine housing.
Abstract:
A Helmholtz damper, especially for damping pulsations in a combustor of a gas turbine, including a damper volume, which can be connected to a damped space by means of a neck tube. The Helmholtz damper further includes a piston, which is moveable within the damper volume and divides the damper volume into a variable first part (V1) on one side of said piston. The variable first part (V1) is connected to the neck tube, and a correspondingly variable second part (V2) on the other side of said piston. The control mechanism is substantially simplified in a more compact design by the piston being driven by a pressure drop (Δp) between the first and second part (V1, V2) of the damper volume.
