Blade Element Theory Plugin
« on: October 30, 2013, 02:43:58 pm »
Would it be complicated for someone to write a Blade Element Theory plugin for Outerra so aircraft will act the exact same way as they do in X-Plane?

Outerra is using JSBSim which has Blade Element Theory Simulation built-in.

Are you positive about that? I thought it currently used data files like MSFSX does?

Yep! The flying stuff is handled by JSBsim and ground vehicles and physics are handled by Bullet.
Here are the features of JSBsim
http://jsbsim.sourceforge.net/links.html

If you search for Blade Element theory in that page you`ll find out that its implemented.

Happy flying!

Doesn't jsbsim use tabular?

IIRC blade-element theory, as used by x-plane, is unsuitable for high-speed aircraft, even with low dt it needs to fall back to tabular...

I cant find tabular (whatever that is) in the JSBsim page. It might use another kind of simulation for higher speeds.

Hey got a question.

What is the diff between Tabular blade element-theory & IIRC?
