Course description

Sufficiency in flight mechanics and aerospace propulsion. Knowledge of working principles and thermo-fluidodynamic processes of Fluid Machinery and Energy Systems

Conventional and advanced propulsion systems for aircraft

Overview

The objectives of the course is to present a unified modeling approach for conventional and advanced aircraft powertrains that takes into account the specifications and the performance of their main components (energy converters, energy storage systems, energy transformes) and the flight mechanic of the aircraft

 

Learning Outcomes; after the course the student should be able to

*Describe the working principle of propellers and internal combustion engines;

*Compare performance and fuel consumption of piston, Wankel and turbine engines in flight and at part load;

*Describe and compare conventional and advanced supercharging systems;

*Describe the advantages and disadvantages of more electric aircraft, more electric engines, hybrid electric aircraft;

* Describe the working principle and compare different technologies of electric machines and electri storage systems;

* Simulate and optimize the energy flows in advanced aircraft powertrains.

 written, project work

The exam consists of two parts  

the first part is a written test; the student is asked to illustrate one theoretical topic; it is aimed to verify to what extent the student has gained knowledge and understanding of the selected topic of the course and is able to communicate about his/her understanding;

the second part: a project works regarding the simulation and/or optimization of an advanced powertrain; it is aimed to determine to what extent the student has problem solving abilities and the capacity to integrate different concepts and tools.
