Compact Gas Turbine Engine with Effective Turbine

Abstract:

This project is investigating an innovative compact configuration of the gas turbine
engine that has unusually effective cooling of turbine blades. This could result
in higher turbine inlet temperatures, power, and efficiency than is common in turbines.
Because of its inherent low pressure ratio, the engine would be suited to, but not
limited to small scale applications. Phase I will study the effectiveness of blade
cooling and the potential benefits of elevated allowable turbine inlet temperatures
and explore the necessity for regeneration in a low-pressure-ratio, gas turbine engine.
If power and efficiency are enhanced as preliminary estimates would indicate, the
engine could compete for many applications now employing much more bulky piston engines.
It would be particularly attractive where a high degree of portability is important
as in emergency power or pumping stations, and vehicle propulsion.
Possible applications include efficient, high-output emergency power sources for
electricity, vehicles propulsion, or pumps for fire fighting or flood drainage.
