In-engine performance evaluation of a mixed-flow impeller with a crossover diffuser compressor stage

Abstract This study evaluates the in-engine performance of a mixed-flow impeller with crossover diffuser compressor stage designed for the CAT250TJ micro gas turbine engine. The upgraded compressor configuration was analysed using CFD simulations in Ansys® Fluent® and thermodynamic cycle modelling in Flownex® SE, then...

A fixed-pitch propeller design and performance evaluation tool for a free turbine, micro turboprop application

In recent times, the conversion of thrust-producing micro gas turbine (MGT) engines to a power-based, free turbine configuration has been increasingly investigated. In such applications, free turbine power loads often include electrical generation systems, turboshaft, and turboprop configurations. In a converted micro...
