Scrounging on the web, Raymer, Anderson, McCormick, Etkin, Roskam from the Lewis University library, and some cut-n-paste from Tony Peden's configs. I then tweaked some things to make it more flyable. The yaw values have been tweaked because I don't know yet how to model a yaw damper. The "dihedral effect" is a hack, but it makes the airplane behave nicely. An alternative would be to raise the z-location of the AC_AERORP. Once I get smart on HUD design, I'll do more testing and make some final tweaks based on what I remember from flying it 20 years ago. What I'd like to do is keep the entire <AERODYNAMICS> section in a separate file, which could be called generic_jet_fighter_aero.xml, or something like that. Then people could more easily build 95% accurate models of any of the hundred-or-so jet fighters without having to learn aerodynamics. Someone who wanted to model some weird behavior, lag the F-100's adverse yaw problem, or the F-104's roll-pitch coupling could always do it the old-fashioned way. Also, the same for the jet transport, the <AERODYNAMICS> section of the 737 configuration could become generic_jet_transport_aero.xml. Just trying to get product out the door :) Dave _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
