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,
