Abstract
Abstract The friction impulse turbine includes four basic sections in order as follows: an air compressor section, a combustor section, a compressor drive section and, finally, the power output section deriving power from the hot gases from the combuster. These components are found in other turbines but, due to the design of the drive blades and lack of recirculation of a portion of the exhaust gas, they are more expensive to build and less efficient. The basic advantages of my turbine include each of the following: A. LESS EXPENSIVE TO BUILD; B. LESS DELAY IN RESPONDING TO CHANGES IN POWER SETTINGS; C. NO CLOSE TOLERANCES; D. SIMPLIFIED TURBINE BLADE DESIGN, MAKING IT EASY TO MANUFACTURE; E. BETTER EFFICIENCY DUE TO HIGHER COMBUSTOR TEMPERATURES; F. LESS POLLUTION IN THE EXHAUST; G. BETTER CONTROL OVER THE COMBUSTION PROCESS; AND H. REDUCED NOISE.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
355 words
A turbine means, comprising: a casing means having an air inlet and an air outlet therein, an elongate rotatable shaft means supported within the casing means and extending axially thereof, first compressor blade means fixed on the shaft means in the casing means for rotation with the shaft means to draw air inwardly through the inlet and force it outwardly through the outlet, fuel combustion means adjacent the casing means, said fuel combustion means including an inner combustion chamber surrounded by an exhaust gas mixing chamber to mix exhaust gas with the main flame in the combustion chamber, and an outer chamber for circulating exhaust gas over the exhaust gas mixing chamber to control the temperature of the gas delivered to the turbine means, a first passage means extending from the outlet to the fuel combustion means for delivering air from the first compressor blade means to the fuel combustion means, a compressor drive turbine means fixed on the shaft means, an output drive turbine means fixed on the shaft means, separate passage means extending in parallel from the fuel combustion means to each of the compressor and output drive turbine means for separately delivering exhaust gases from the fuel combustion means to each of the turbine means, a common exhaust gas manifold adjacent the casing means for each of the turbine means, separate exhaust passage means leading from each of the turbine means to the exhaust manifold means to deliver exhaust gases from the turbine means to the exhaust manifold means, second passage means connected between the exhaust manifold means and the casing means to deliver a portion of the exhaust gases from the exhaust manifold means to the casing means, a second compressor blade means fixed on the shaft means adjacent the first compressor blade means for receiving said portion of the exhaust gases from the exhaust manifold means to compress the Exhaust gases, and third passage means leading from the second compressor blade means to the fuel combustion means for delivering the compressed exhaust gases to the fuel combustion means to increase the efficiency of the turbine and reduce the pollution effect.
