CFD is increasingly used in the design and optimisation of wings of small UAVs. Airfoils of these small vehicles operate at Reynolds numbers where laminar-turbulent transition has a pronounced effect on performance. This paper presents a validation of four transition models using a steady RANS solver for three different airfoils at Reynolds numbers between 60,000 and 200,000.
