"The two-element system consisted of the NLR 7301 airfoil section and a flap element of 32% chord at a deflection angle of 20[degrees], a gap of 2.6% chord, and an overlap of 5.3%."
A closer look will show the actual airfoil section varies with each blade station to provide the most efficient angle of attack for not only the rotational speed but also when considering the aircraft's forward speed.
where [C.sub.L,[alpha]] is the airfoil section lift slope, [[alpha].sub.0L] is the zero-lift angle of attack, and [[alpha].sub.e]([theta]) is the effective local angle of attack.
Giorgio Piatti, Airborne Systems' design manager, emphasised that the Hi-5 achieved a glide ratio very close to that of the Hi-Glide with a canopy that is both simpler to build and more intuitive for riggers to pack and jumpers to handle; the latter thanks in part to the GMS: "The glide modulation changes the airfoil section. You maintain the ability to control your heading, but instead of gliding with a five-and-a-half-to-one glide ratio, you are descending with a one-to-one

A bespoke rear wing gives the car enhanced visual presence and delivers powerful additional downforce, thanks notably to the structure of its airfoil section.
The leading edge is the part of the wing that first contacts the air; alternatively it is the foremost edge of an airfoil section.
[1, 2] presented results for a typical airfoil section basedon time domain simulations.
NACA4412 airfoil section with flap in extreme ground effect were numerically investigated by Ockfen and Matveev [9].
However, each blade required two holes, which reduced the airfoil section and could generate significant notch stresses.

This insight spurred the development of our 3DS blade, in which the airfoil section changes along the length of the blade to match the complex 3D flow field.
