A COAL-BURNING GAS TURBINE LOCOMOTIVE DESIGN

Principal details of the open-cycle layout, using electric drive are given. Thermodynamic considerations, together with the physical properties of the materials of construction, suggested an intial gas temperature of 1,300 deg F, at the turbine inlet, and a pressure ratio of 4-8/1. The turbine will deliver 4,120 h.p. to the reduction-gear pinion at 24 percent shaft thermal efficiency, when the combustion efficiency is taken to be 96 percent. The chief components of the gas turbine: an axial-flow compressor; a reaction turbine, a direct-current generator with two shafts; reduction gears (a pinion between two low-speed gears, which drive the two main generator shafts); a regenerator; a combustor and, fly-ash separator.
