It was the first Sikorsky helicopter designed purely for commercial rather than military use. The University of Illinois at Urbana-Champaign has a databa. Sikorskys design work on the S-70 helicopter (which was selected for use by the United States Army as the UH-60 Black Hawk) was utilized in the development of the S-76, incorporating S-70 design technology in its rotor blades and rotor heads.
#Helicopter airfoil how to#
The rotation of its airfoils is created by either a gas-turbine(s) or piston engine driving a main gearbox which then turns both the main rotor and tail rotor together. In this Creo Parametric tutorial video, you will learn how to use airfoil data to create splines. I would theorize that this has something to do with autorotation, but I quickly get out of my depth.īell 200 XV-3 (2 blade rotor) NACA 0015 NACA 0015īell 200 XV-3 (3 blade rotor) NACA 23015 NACA 23015īell 205 UH-1 Iroquois NACA 0012 NACA 0012īell 205 UH-1 (new blades) Bingham 12% Bingham 8%īell 206 OH-4 NACA 0011 mod NACA 0011 modīell 206 OH-58/TH-67 NACA 0012 mod (11.3%) NACA 0012 mod (11.3%)īell 209 AH-1 Cobra NACA 0009.3 mod NACA 0009.3 modīell 209 AH-1 (K747 blades) Boeing VR-7 Boeing VR-8/-9īell 209 AH-1J Sea Cobra Wortmann FX 69-H-098 Wortmann FX 69-H-098īell 212 UH-1N NACA 0012 NACA 0006 ("droop snoot")īell 214A Wortmann FX 69-H-098 Wortmann FX 69-H-098īell 214B Wortmann FX 69-H-098 Wortmann FX 69-H-098īell 222 Wortmann FX 71-H-080 Wortmann FX 71-H-080īell 249 Hueycobra Boeing VR-7 Wortmann FX 69-H-080īell 292 ACAP Wortmann FX 71-H-080 Wortmann FX 71-H-080īell 301 XV-15 (Boeing ATB) V43030-1.58/VR-7 Boeing VR-8īell 301 XV-15 (original blades) NACA 64-935/528/118 NACA 64-(1. In a helicopter or ‘Rotary-Wing’, the airflow over its airfoils is created by rotating each airfoil through the air.
In my own work, I have already identified that the tip airfoil of the Bell 212 is not exactly NACA0006, because the outboard 80% is modified by inserting a wedge at about 25% chord to produce a "camber". Ive clipped out the piece for the Bell helicopters below. I've clipped out the piece for the Bell helicopters below.
The list is quite extensive, including almost every make and model of aircraft I can think of.
