Novel Gas Turbine Engine Combined Cycle for Contrail Reduction

This is a paper submitted for the 2025 AIAA Aviation conference. In this report a novel engine cycle is described with the intention of improving performance and reducing contrail formation. The engine uses water injection to increase turbine power output as well as extracting steam from the exhaust to reduce contrail formation. In this document the cycle is described and modeled, with its performance and contrail production assessed as a function of key cycle parameters.
