Influence des aspect ratios sur la maniabilité, vitesse et accélération

Gunnar Biniasch a lâché ce commentaire que je trouve très intéressant, les idées reçues en prennent un coup, mais c'est juste .

Aspect ratio of the front wing on it's own has nothing to do with how the foil will turn. High Aspect (AR10 or more) can turn faster and with less resistance than most Mid or low aspect front wings. Fuselage length and stabiliser type and size have more effect on turning than the front wing.

As to the differences you are asking about, again it is hard to generalise as there are so many factors that make a front wing fly like it does.

But some basics apply IF and only IF the Profiles and profile progession, washout and volume are identical:

* low aspect large surface: Slower and more drag
* low aspect small surface: Same speed, but more accerleration
* high aspect large surface: More Glide and Lift, a little bit more resistant to roll
* high aspect small surface: Faster accerleration, slightly higher speed
