Angel101 Posted December 19, 2016 Posted December 19, 2016 Seems that the FM has changed again in last update. Now it behaves like a few patch before. Again retains better energy. I need to add any tacview graph?

I need to add any tacview graph? Cpt. Smiley advised in the readme of a change coming regarding drag on turns - if I recall correctly.
Zaz0 Posted December 19, 2016 Posted December 19, 2016 Forgive Angel, he just lost a dogfight tournament at our Squad using a Su-27 against a M2k and he's angry xD Seriously, it seems that M2k almost not drain energy at high-G turns.

Angel101 Posted December 21, 2016 Author Posted December 21, 2016 Hi all, reviewed the code and nothing between this and last update should have affected turn rate performance and also confirmed no regression on that. So without substantiating data, I can't confirm or agree that anything is different from the previous update. The only changes made to the EFM was drag modeling at extremely high dynamic pressures (not really a driving factor of turn rate performance in maneuvering combat since this means EXTREMELY high dynamic pressures) and engine modeling at extreme altitudes. I'll keep looking into it, but that's what I've found so far. Hi thanks for your attention. We are going to create a turn performance chart with the raw data from DCS, (I have a friend who does these charts in his job) :thumbup: Maybe that helps to track changes in FM. Just a question... I searched similar charts for that module and found that 2 in the forum. and the question is: Are any of these charts useful for comparison?
Robin_Hood Posted December 21, 2016 Posted December 21, 2016 (edited) Well, AFAIK the first one is from IRL but is an estimation, not an official chart, while the second one is from another sim (there are more where that one comes from, for different loadouts and altitudes). The latter used to be included in the DCS manual (first version), before they decided it was better to remove them (as they come from another sim, and do not represent the actual DCS flight model). I am hoping there will be a way that RAZBAM makes these and other kinds of charts themselves when the FM is final (of course, it would be a waste to do it before). FWIW, my latest testing are more along those lines (though maybe that is some artifacts from the G-limiter when keeping the stick full aft while slowing down) Edited December 21, 2016 by Robin_Hood 2nd French Fighter Squadron
myHelljumper Posted December 21, 2016 Posted December 21, 2016 Thanks for that, very interesting graph. What did you used for the measurements ? Tacview ? Helljumper - M2000C Guru Helljumper's Youtube https://www.youtube.com/channel/UCK3rTjezLUxPbWHvJJ3W2fA
Robin_Hood Posted December 22, 2016 Posted December 22, 2016 (edited) Tacview* for TAS and G, and I then used the formula for turn rate, with a second export for Mach number (also possible to simply check the conversion factor). I prefer to do it that way, rather than using Tacview's turn rate, although the results should not be significantly different and the overall shape is the same. * Professional edition, with data exporter Edited December 22, 2016 by Robin_Hood 2nd French Fighter Squadron
