摘要： In a micro gas turbine engine, a capacitive sensor is used for measuring a tip clearance of a radial compressor section thereof, and an actuator is used for axially displacing a rotor shaft in response to an output from the capacitive sensor. Because the capacitive change gives an accurate measure of the size of the tip clearance, a particularly high sensitivity can be achieved in parts where the tip clearance is small, thereby providing a highly precise tip clearance control.

摘要： What is described is a device for setting the gap dimension for a turbomachine, in particular a gas turbine, with a multiplicity of moving blades arranged in at least one moving-blade row of a rotor arrangement, with a guide-vane carrier surrounding the rotor arrangement and a turbine casing surrounding the guide-vane carrier, with a multiplicity of heat accumulation segments which are arranged on the guide-vane carrier of the rotor arrangement and at least opposite the moving-blade tips and which, together with the moving-blade tips, enclose a gap, and with at least one drive means which projects radially through the turbine casing and the guide-vane carrier and is operatively connected kinematically to at least one heat accumulation segment and which, when actuated, causes a radial spacing of the heat accumulation segment. The invention is distinguished in that the heat accumulation segment has, in the flow direction of the turbomachine, a conical contour facing the rotor arrangement and is arranged so as to be displaceable parallel to the flow direction, and in that the drive means is connected to the heat accumulation segment directly or via an eccentric unit, in such a way that, when the drive means is actuated, the heat accumulation segment is displaced, with the result that a radial spacing between the heat accumulation segment and the moving-blade tips can be set.

摘要： The present invention relates to a turbine having a housing (11) and a rotor (12), the housing (11) being provided with a plurality of rows of guide vanes (13) and the rotor (12) being provided with a plurality of rows of rotor blades (14). On the housing (11), there is a guide ring (18) which is provided axially between in each case two rows of guide vanes (13), which guide ring, together with the associated row of rotor blades (14), delimits a gap (21). According to the invention, the guide ring (18) is adjustable in order to change the gap (21). The size of the gap (21) can then be predetermined by adjusting the guide ring (18) and can be optimized according to the specific application.
