Hoar frost effects on aerofoil efficiency
After a thread in Private Flying, I wondered if anyone had any pointers to any practical research on how and why a frost coated wing is reduced in efficiency. Especially the differences between a laminar flow wing and a more conventional design on a piston light aircraft.

http://icebox-esn.grc.nasa.gov/ It is exactly the frost which makes for unpredictable loss of cl (lift) and increase of cd (drag). To properly determine the impact a granularity must be defined and then tested in the wind-tunnel. So, the best is stick to the "clean wing" principle and add that extra time to properly de-ice even the slightest touch of the winter fairy. ;) error_401 |
