SWB Turbo Shaft
Description:
One of SWB’s newest innovations is a Sidewinder configuration Miniature Turboprop Engine (MTE). It utilizes a highly developed gas producer, with a fine lineage of previously successful SWB Turbines turbojet engines (since 1987), SWB’s U.S. Patents (granted 1998), and low-cost production potential (because it’s rotating components are derived from the commercial turbocharger/vehicle industry). SWB Turbines has proven that its customers, including the Army, can benefit from the well-developed turbocharger turbine and compressor component base. U.S. and other major countries have cultivated a major dependence on truck transportation, transitioning from trains, with increasing dependence on turbocharged diesel power plants. This is the backbone of the U.S. Transportation System. Turbocharged diesel engines have become the standard through a wide range of horsepower, resulting in very high savings leverage for miniature turbines, select super alloys and advanced rotor aerodynamic performance.
