ResonantCard1 Posted March 21, 2019 Posted March 21, 2019 Hi guys, what is the thrust rating for the MiG-21bis secondary afterburner? I compared the thrust figures for the R25-300 in the manual and Yefim Gordon's MiG-21 book, and saw some discrepancies, although they are small ones. The thrust in the book is separated in mil power, take-off (which I assume is First Afterburner) and contingency mode. For contingency, 2 wildly different figures are given. One of them, 7100 kgf, is close to the afterburner figure we see in our manual (~7200 kgf after conversion). The other figure is 9500 kgf. Now, is the afterburner figure in the manual given for the second afterburner or for the first one? In any case, which source is used in the manual for these technical specs? Thanks for any help, ResonantCard1 Main: MiG-21bis, because pocket rockets are fun Si Vis Pacem, Para Bellum

ResonantCard1 Posted March 21, 2019 Author Posted March 21, 2019 Is this how it's modelled in-game? What's the SFC for the second stage AB? Main: MiG-21bis, because pocket rockets are fun Si Vis Pacem, Para Bellum
foxbat155 Posted March 21, 2019 Posted March 21, 2019 That's real engine data, how is modeled in game?, well, only developers knows this, SFC for second reheat don't know honestly.
