The Intercooled-Supercharging Gas Turbine Engine 891875

A new concept in gas turbine prime mover is proposed. This new gas turbine uses the intercooled supercharging to reduce the exhaust energy loss, thus eliminating the need for regeneration. We establish the feasibility of a broad operating range for the proposed gas turbine. Its thermal efficiency at the design condition is comparable with, while the overall efficiency performance is better than, the regenerative gas turbine. The most important advantage of the proposed gas turbine as an alternative to the regenerative gas turbine is the potential reduction in size and weight.
