Dark_Knight_667th Posted July 20, 2003 Posted July 20, 2003 been speaking with Julian data and a few others..as well as doing some reading of my own. Julian confirmed what I have been thinking for a bit. These following lines in the wing, tail, rudder, etc all affect the roll rate and roll inertia. and will also possibly fix the unwanted roll when yaw (rudder) is applied. As taken from the F100 D data.ini wing section. CLa=0.5105-Lift coefficient with aileron applied CD0=0.0011 CDL=0.0014-coeffiecient drag vs lift Cmq=-0.1944-this is mass coefficient of some sort..working on full definition Cmad=0.0170-same with this..something with mass with aileron applied which may be the solution to the roll inertia.. Cyb=-0.0085 Clb=-0.0494 Clp=-0.0434-lift coefficient with elevator applied ( I think) Clr=0.0164--lift coefficient with rudder applied..this may be the excess roll we see when rudder is applied.. Cnb=-0.1397 Cnp=0.0021 Cnr=-0.0037 I'll break these down in further detail as I learn more. DK Quote
+Dave Posted July 20, 2003 Posted July 20, 2003 DK Talk to Column5 he is working with FM's alot and has figured out a good amount of information. Quote
navychief Posted July 20, 2003 Posted July 20, 2003 Thanks for your efforts. I have the same roll inertia difficulties when flying the Skyhawk also. Chief Quote
Andy Bush Posted July 20, 2003 Posted July 20, 2003 Roll inertia and rudder induced roll are two completely different subjects. SFP1 has a problem with roll inertia...it does not have a significant problem with rudder roll. The roll inertia issue is bad FM aerodynamics. The rudder roll issue is exaggerated FM aerodynamics in most cases. In the game, the F-104 exhibits rudder roll, and this is incorrect. But it is correct for the other flyable aircraft. If the game has an exaggeration, it is in that the effect is too noticeable at low AOA. Quote
BERNARD1943 Posted July 20, 2003 Posted July 20, 2003 :D thanks so much for this post. I have a personal wish which would be that you update and complement your great review at simhq after patch 2 is out. First because we can only hope this patch will change important things in the sim and second because it is certainly important to clarify a few issues which are still not absolutely clear in the community. Like you are doing here. Quote
Dark_Knight_667th Posted July 21, 2003 Author Posted July 21, 2003 Andy..it was in regards to the F104 that I posted the bit about the rudder induced roll :D DK Quote
