1. Aerodynamic Aspects of Propulsion Integration for Next-generation Commercial Aircraft
Abstract : Propulsion integration is one of the most challenging aspects of aircraft design. It requires a multidisciplinary approach involving aerodynamics, propulsion, structures, weight, noise, and control systems. READ MORE

2. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion
Abstract : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. READ MORE

3. Fluidic Microsystems for Micropropulsion Applications in Space
Abstract : Spacecraft on interplanetary missions or advanced satellites orbiting the Earth all require propulsion systems to complete their missions. Introducing microelectromechanical systems technology to the space industry will not only reduce size and weight of the propulsion system, but can also increase the performance of the mission.

4. High-Temperature Microfluidics for Space Propulsion
Abstract : In this thesis, microfabrication methods and tools for analysis of heated cold-gas microthrusters are presented, with the aim of improving their reliability and performance. Cold-gas thrusters operate by accelerating pressurized gas through a nozzle. READ MORE

5. Experimental Aerothermal Study of Internal Jet Engine Structures
Abstract : In commercial aviation, efficiency improvements may be gained by aerodynamic optimisation of its structural components, such as the intermediate compressor duct (ICD) and the turbine rear structure (TRS). These components have frequently been overlooked in favour of compressor and turbine module optimisation. READ MORE
