Task

The use of simulation tools for precisely modeling thermodynamic, mechanical, and electrical processes is becoming increasingly important in the research and development of novel propulsion architectures. In particular, when investigating hybrid-electric propulsion concepts, the ability to model transient operating states is of central importance, alongside steady-state design at the design point and the analysis of partialload conditions in off-design operation.

As part of this work, a generic engine architecture (e.g., a two-shaft turbofan) will first be built in T-MATS and modeled for various operating states (design point, off-design, and transient operation). Subsequently, 2–3 different propulsion architectures with increasing degrees of hybridization (e.g., conventional, parallel-hybrid, series-hybrid, or turboelectric) will be implemented in transient operating mode and compared and evaluated against one another.

Objectives:

• Literature review on T-MATS as well as the complementary toolboxes EMTAT and TSAT and their previous use for hybrid-electric propulsion simulations.
• Setup and validation of a generic reference architecture in T-MATS (design point, off-design, and transient).
• Implementation of 2 propulsion architectures with different hybridization paths in transient mode.
• Analysis and evaluation of dynamic system behavior.
