Aerodynamic performance of low-to-moderate aspect ratio wings at low Reynolds numbers
This thesis presents wind tunnel results of wings of low-to-moderate aspect ratio (2$\leq$\AR$\leq$5) tested at low Reynolds numbers (40,000 to 160,000). All models tested had a chord length of 3~in and a wingspan of 7 to 17.5~in. Experiments were conducted in the low-turbulence wind tunnel in the …
