Master thesis assignment: Tilt-rotor-wing aerodynamic modelling for aeroelastic analysis — Hybrid, Amsterdam, Noord-Holland, Netherlands.
Job description
What will you be doing?
Tilt-rotor aircraft offer a significant advantage over conventional helicopters in terms of cruise speed and efficiency. NLR is currently preparing a wind tunnel test of a tilt-rotor-wing configuration. The focus of the wind tunnel test is aeroelastic stability (i.e. flutter and limit-cycle oscillations). The goal of this test is to gather data for validation of comprehensive analysis tools. To assist the aeroelastic wind tunnel model design & development, simulations with a comprehensive rotorcraft modelling software are performed as well.
The comprehensive modelling software that is used for these investigations offers various methods to model the aerodynamics of the tilt-rotor-wing model. You will investigate what kind of aerodynamic modelling is most suited with regards to aeroelastic analysis. To do so, you will perform a literature study and then evaluate various aerodynamic models, for primarily the wing and nacelle, ranging from low to mid-fidelity. Furthermore, CFD simulations of the nacelle shall be performed, starting from an existing grid, to obtain inputs for the low-fidelity model. You will compare the results of the various aerodynamic modelling approaches and assess their effect on aeroelastic stability predictions as well as compare their computational cost.
Result
Study into low to mid-fidelity aerodynamic modelling approaches for tilt-rotor aeroelastic analysis. CFD analysis of part of the tilt-rotor-wing model.
Duration of the internship?
9 months, starting date as soon as possible/upon agreement.
What do we expect from you?
- Master student in Aerospace Engineering;
