Unmanned Aerial Vehicles have encouraged us to rethink the way conventional 
aerodynamic design is conducted. The low speed, size of aerodynamics 
surfaces, lifting or propulsive, and altitude of operation reduces 
significantly the Reynolds number (Re) regime at which they operate. On the 
other hand, Micro Air Vehicles (MAVs) are subject to high turbulence 
intensity levels due to perturbed atmospheric conditions in the urban 
environment. In this low Re (10E3-10E5) and high turbulence intensity 
regime, the behaviour of the flow over the aerodynamic surface is more 
complex to predict although it has been hardly addressed by the scientific 
community so far. In a laminar state, the flow is more prone to separate 
causing considerable deterioration in performance, stability of the overall 
vehicle or in worst case scenarios with more severe consequences such as 
massive stall or control loss. In a turbulent state the boundary layer (BL) 
is more resilient to separation, therefore it is important to predict when 
the flow will transition. 

This doctoral campaign aims at assessing the transition prediction 
capability as applied to MAVs, including fixed-wing and rotary-wing 
aerodynamics subjected to the surface curvature and roughness, the 
turbulence characteristic of the ambient region of operation and background 
noise. Wind tunnel experiments will be conducted with varying turbulence 
intensities and numerical methods will be assessed based on the experimental 
findings. Candidate should have previous experience in wind tunnel testing 
and a solid foundation in fundamental fluid mechanics or aerodynamics. 
Previous experience in conducting numerical simulation using commercial or 
in-house codes will be appreciated.

This PhD is funded by ISAE-SUPAERO (DGA) and ONERA, it will be under the 
supervision of Profs Jean-Marc Moschetta and Erwin Gowree at ISAE-SUPAERO 
and Dr Gregory Delattre at ONERA, Toulouse.
