Abstract

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, Ahead of Print.
This study addresses the dual need for an improved thrust-to-weight ratio and robust operation over a wide incidence range under transonic conditions. High through-flow (HTF) turbines, characterized by high loading and large flow coefficients, exhibit ...
