- Summary
-
An investigation of the low-speed static aerodynamic characteristics of three ram-air-inflated low-aspect-ratio fabric wings has been made in the Langley full-scale tunnel. The wings which were rectangular in planform and had an airfoil-shaped cross section were open at the nose to allow air to enter and inflate the wings; the payload was suspended on lines below the wings. Effects of four different test setups were also determined. The results indicated that the untrimmed maximum lift-drag ratios of the wings ranged from 1.9 to 2.7 and that the untrimmed maximum lift coefficients varied from about 0.9 to 1.1.
