ABSTRACT:
A low velocity high torque gas turbine, using the Brayton Cycle, and having a high velocity compressor with a separation of the working fluid into two columns, one external for cooling and the other internal for primary fuel injection and combustion. A feature is the recycling of a proportion of the combustion gases that is then combined with the external column of heated cooling air for secondary fuel injection and combustion. The primary and secondary combustion fluids are comingled, the diffused and separated column of cooling air being advantageously employed to supply an excess of oxygen in the working fluid to adequately support combustion. The tubular turbine shaft for recycling combustion gases, and the working fluid distributor that combines the primary and secondary working fluids, and the speed increasor for the compressor, all characterize this invention.
