A Feasibility study of new atrex engine system of aft-turbine configuration

摘要

A feasibility of ATREX (Air-turbo-Ram expander cycle) engine with conventional aft- turbine configuration has been studied to be developed in about 10 years, if the development project has started under enough resources. The novel tip-turbine of the original ATREX engine is replaced by a conventional aft-turbine, and the maximum turbine inlet temperature (TIT) is reduced to 1200K, to realize the engine by only using approved metal technologies of modern jet engines. The capability of the performance has been shown by parametric studies by changing components' design parameters.
