Bell Shaped Lift Distribution

[EngineerW]

I was wondering if anyone has or has seen a software program that helps calculate the required wing twist to achieve the bell shaped lift distribution that the horten brothers used on their aircraft. There was a program called Laschka Professional but I think its in German and I dont speak German.


Any help would be much appreciated

Profili (http://www.profili2.com/eng/default.htm) is a program that wraps some of the NASA aerodynamic programs, generates a number of graphics and graphically present pressure distribution for airfoils under a number of user-defined criteria. It has a free demo that allows you to see most of the program features, and it is only $10 to register (for life) and unlock all the features. I'm unfamiliar with the program you mentioned, but this one may be what you need.
