A scalable model for design and control of turboprop engines for advanced propulsion systems

In this study, a methodology is proposed for designing turboprop engines and evaluating their off-design performance. It involves optimization steps for the choice of some of the system design parameters and adaptive scaling methods for the turbomachinery and propeller maps. Results show that it leads to a good estimation of the performance of the real architecture of the existing aircraft and is suitable to be used for innovative application such as the sizing of the engine for advanced propulsion systems like the hybrid-electric architectures with increasing hybridization factor.
