Modeling and Simulation of a Hybrid Electric Engine Architecture for a Military Flight System

I just recently finished my master's thesis at the Technical University of Munich (TUM) on the topic of 'Modeling and Simulation of a Hybrid Electric Engine Architecture for a Military Flight System' in which I explored, modeled and simulated different propulsion and power supply systems for a military surveillance drone in NPSS in cooperation with IABG mbH and MTU Aero Engines AG.

Due to IABG mbH company restriction, I am unfortunately only allowed to publicly provide the abstract and assignments of the thesis. If you are however interested in the results, I will happily provide more information via mail.

Abstract
As part of the examination of future engine concepts for military flight systems a hybrid electric engine architecture of a medium-altitude long-endurance (MALE) unmanned aircraft system for surveillance purposes was to be evaluated in this master thesis.
Initially, the hybrid electric engine system simulation HEPSS is being developed in NPSS as a basis for this. Electrical engine components are either provided through an open-access NASA element library or exclusively being programmed. To ensure an error-free simulation all electrical elements are also validated. The European MALE RPAS is used as the reference flight system for the modeling of a serial electric engine system and subsequently analysed with regard to operating strategies, various degrees of hybridization and future technology levels.
Finally, key advantages for operation are determined and parameters for hybridization are outlined.

Assignments
