    Abstract: A turbomachine variable-pitch stator blade is disclosed. The stator blade includes an aerofoil, extended on one side by a pivot by which it is mounted so as to rotate in a bore of the casing of the turbomachine, and a plate, between the aerofoil and the pivot, perpendicular to the line formed by the aerofoil and the pivot. Since the face of the plate opposite to the aerofoil includes a first zone and a second zone, the first zone being subjected to an intense friction with the wall of the casing because of the transverse forces applied to the aerofoil, the thickness of the plate on the second zone is reduced relative to the thickness of the plate of the first zone. Therefore, it is possible to reduce the weight of the blade without loss of performance.

  • Publication number: 20100284793
    Abstract: A method of repairing a variable vane for a gas turbine engine includes the steps of positioning a trunnion of a variable vane within an electrical discharge machine environment, and connecting the trunnion as a first electrode through an electrical discharge machine power generator to a second electrode. The second electrode is formed of a hard metal coating. A spark is created between the trunnion and the second electrode such that material from the second electrode is deposited on an outer surface of said trunnion. Further, a variable vane having a trunnion reconditioned by this method is disclosed and claimed.

  • Publication number: 20100266389
    Abstract: The present invention relates to a turbomachine variable-pitch stator blade comprising an aerofoil (12), extended on one side by a pivot (14) by which it is mounted so as to rotate in a bore of the casing (3) of the turbomachine, and a plate (13), between the aerofoil and the pivot, perpendicular to the line formed by the aerofoil and the pivot. The blade is characterized in that, since the face of the plate opposite to the aerofoil comprises a first zone (20) and a second zone (22), the first zone (20) being subjected to an intense friction with the wall of the casing (3) because of the transverse forces applied to the aerofoil (12), the thickness of the plate on the second zone (22) is reduced relative to the thickness of the plate of the first zone (20). The invention makes it possible to reduce the weight of the blade without loss of performance.

  • Publication number: 20100260595
    Abstract: A turbocharger (10) for an internal combustion engine includes a compressor (12) having an impellor (16) disposed in a compressor chamber (18). The compressor chamber (18) receives fluid flow. A flow regulation mechanism (30) is disposed in the compressor (12) and includes a diffuser cover (32) and a recirculation gate (36). The diffuser cover (32) is moveably disposed in a diffuser passage (34) from a first position permitting fluid flow through the diffuser passage to a second position at least partially impeding the fluid flow. The recirculation gate (36) is moveably disposed in the compressor chamber (18) from a first position closing a recirculation groove (48) to a second position opening the recirculation groove to fluid communication with the compressor chamber.

  • Publication number: 20100254799
    Abstract: A shroud for vertical axis wind turbines. The shroud contains vanes that direct airflow to the turbine blades to increase efficiency. The vanes in the shroud further provide a means to close entirely the turbine from adverse weather conditions. The vanes are operated utilizing electrical feedback from the rotational speed of the turbine.

  • Publication number: 20100247288
    Abstract: Rotary wing system with a rotating blade rotating about a rotation axis. The system includes a fluid damper with a damper fluid for controlling a troublesome motion. The fluid damper has an inboard end and an outboard end, the damper inboard end attached to a first rotary wing system inboard member proximate the rotation axis and the outboard end attached to a second rotary wing system outboard member distal from the rotation axis. The fluid damper contains a damper fluid volume in at least a first working chamber which is worked by a relative motion between said first rotary wing system inboard member and said second rotary wing system outboard member to control the troublesome motion.

  • Publication number: 20100236238
    Abstract: An internal combustion engine with a plurality of cylinders, which are each assigned an inlet valve, an outlet valve and a combustion space, with an inlet camshaft connected to a camshaft adjuster, with an outlet camshaft connected to a camshaft adjuster, with a switchable inlet-valve drive which has a plurality of inlet cams for actuating the respective inlet valve, with a switchable outlet-valve drive which has a plurality of outlet cams for actuating the respective outlet valve, and with an exhaust-gas system. The internal combustion engine is operated with compression ignition or with spark ignition as a function of the operating point. For this purpose, for the compression ignition, a specific residual exhaust-gas quantity is set in the combustion space. Furthermore, the internal combustion engine is operated as a function of the operating point by means of an outlet cam.

  • Publication number: 20100236237
    Abstract: A method for operating an internal combustion engine with compression ignition or with spark ignition as a function of an operating point. A specific residual exhaust-gas quantity in the combustion space is set for compression ignition. The internal combustion engine is operated as a function of the operating point by an outlet cam, by which a first outlet opening phase and a second outlet opening phase take place. The second outlet opening phase commences during an inlet opening phase. At a first operating point in a compression-ignition mode, a residual exhaust-gas quantity in a combustion space is dimensioned as a function of a valve interference set between the inlet and the outlet valve during a charge exchange. At a second operating point in the compression-ignition mode the residual exhaust-gas quantity in the combustion space is dimensioned as a function of a duration of the second outlet opening phase.
