A turbine frame for a turbine engine having an axial centerline, the turbine frame comprising an inner hub, an outer hub encircling the inner hub, a plurality of struts extending between the inner and outer hubs and having a maximum width portion relative to the axial centerline and an airfoil comprising at least first and second fairings mounted to the inner and outer hubs and encircling one of the struts.

Turbine frame and airfoil for turbine frame

A turbine frame for a turbine engine having an axial centerline, includes an inner hub, an outer hub encircling the inner hub, a plurality of struts extending between the inner and outer hubs, at least one vane segment comprising at least first and second fairings mounted to the inner and outer hubs and encircling one of the struts and a single piece outer retaining ring that is operably coupled to the vane segment to fix a radial position of the vane segment relative to the inner and outer retaining rings and methods of assembling at least one vane segment having at least one vane formed from a pair of fairings to an exhaust frame.

Featured is a method for passively-repulsively lifting a rotor assembly () of a flywheel energy storage system (), comprising the steps of mechanically coupling a first permanent magnet () to the rotor assembly () and fixedly positioning a second permanent magnet () proximal to the first permanent magnet () so that a repulsive force is generated therebetween causing the first permanent magnet () to move with respect to the second permanent magnet (), thereby causing the rotor assembly () to be lifted to an operating level. The method further includes applying a radial force sufficient in magnitude and direction to oppose a radial force being generated by the permanent magnet repulsive force. Also featured is a passive-repulsive rotor assembly lift system () for a flywheel energy storage system () and a flywheel energy storage system () including such a repulsive rotor lift system ().

A fuel shield is configured for use in the afterburner of a turbofan aircraft engine. The shield includes wings obliquely joined together at a nose, with each of the wings including an offset mounting tab at a proximal end thereof. The wings and tabs are configured to complement a flameholder vane around its leading edge, with the tabs contacting the vane sidewalls to offset the wings outwardly therefrom and form a thermally insulating gap therebetween.

A permanent magnet motor assembly for use in a flywheel is disclosed, including a rotor, a stator, and a coil positioned in the stator. One or more magnets is attached to the rotor such that magnetic field lines are directed radially toward the coil for generating torque and thus driving the motor. A shield covers the magnet, preventing the magnetic flux lines from impacting a plate on the stator and causing excess heat and energy losses. The shield can be a cup or a snap-fit ring preferably made of magnetic steel which directs stray magnetic flux lines toward the rotor to be converted into useful work.
