The airflow over the wing increases its speed causing a reduction in pressure; this generates a force ( lift) perpendicular to the chord of the aerofoil. The airflow below the wing moves much more slowly generating greater pressure and less or negative lift. Web30 mrt. 2024 · Abstract. This paper presents a novel method for airfoil drag estimation at Reynolds numbers between 4 × 10 5 and 4 × 10 6. The novel method is based on a systematic study of 40 airfoils applying over 600 numerical simulations and considering natural transition.
