Abstract: A combustor for a small gas turbine engine in which a compressor discharges a swirling air flow into the combustor, and a fuel impeller is rotatably connected to the compressor and slings atomized fuel into the combustor in a direction to produce a stagnation zone within the combustor. A plurality of fuel injectors delivers fuel to the inlet end of the fuel impeller. The combustor outlet is a nozzle shape that produces a high enough pressure level in the swirl air flow such that the cooler air flows along the inner combustor wall to form an insulation layer from the hot combustor gas flow within the combustor. The fuel impeller produces a very fine mist of fuel and the stagnation zone produced results in easy starting of the engine and stable combustor burning.

Abstract: An apparatus for generating electric current from a vibrating blade exposed to a fluid flow. in one embodiment, a plurality of blades are secured within a tail cone of a steam turbine and each blade includes a magnet and a coil associated with the magnet to produce electric current in the coil when the magnet moves across the coil. Each blade is designed to have a natural frequency so that the blade will resonate under the influence of the exhaust flow from the turbine in the tail cone. Abutment members are mounted on the blade or the fixed support to limit the range of motion of the vibrating blade so that it does not exceed the fatigue limit. The blades are made from a low damping material such as titanium so that a low frequency is produced.
