SOLVED: Using Helmbold's relation for low-aspect-ratio wings, calculate the lift coefficient of a finite wing with an aspect ratio of 1.6 and an NACA 2412 airfoil section. The wing is at an angle of attack of 4Â°. Compare this result with that obtained from Prandtl's lifting line theory for high-aspect-ratio wings. Comment on the difference between the two results. Assume a span efficiency factor e = 1.

The airfoil data in Appendix D were obtained in the NACA two-dimensional Low Turbulence Pressure Tunnel at the NACA Langley Memorial Laboratory. This facility went into operation in Spring 1941. The tunnel was especially designed for airfoil testing, with a test section 3 ft wide and 7.5 ft high. The wing models spanned the entire test section of width 3 ft, so that the flow over the model was essentially two-dimensional. The chord length of the models was 2 ft. When the tunnel became operationa

SOLVED:The numbering system for wing sections of the NACA five-digit series is based on a combination of theoretical aerodynamic characteristics and geometric characteristics. The first integer indicates the amount of camber in terms of the relative magnitude of the design lift coefficient; the design lift coefficient in tenths is three halves of the first integer. The second and third integers together indicate the distance from the leading edge to the location of the maximum camber; this dista
