The one-piece bar/stem is their first in-house cockpit design. It has NACA airfoil shaping with a slightly 3º backsweep to make it and you a little more aerodynamic. All cables and hoses run ...

In this paper, a method for the determination of the aerodynamic performance characteristics using NACA airfoils is given for three bladed horizontal axis wind turbine. Blade geometry is obtained from ...

NACA laboratories had an interest in B-47A NACA ... of large airplanes led to swept-back wings of high aspect ratio, thin airfoils, and fuselages with high fineness ratios (i.e. long and thin).
