The Soviet nose bobbles more than the Chinese at low speed and low altitude performance (Post Stall). It is affected trying to regain control at low latitude. Chinese is flush with full control of aircraft after high alpha maneuvers.
the Chinese Flanker’s post stall control is superior at moment imo.
Su-27 (VKS) High alpha roll and post stall control. - YouTube
30min internal, 900km roll and pitch, 90° alpha and return to level flight. This Flanker demonstrates less control post stall. Notice the excessive nose bobble and I did not sustain the same alpha any longer than the Chinese.
maybe one of yall whos better at holding a rate in full real in mouse control can help confirm but in the brief periods I managed to hold a rate and altitude it seems the Su-27 is sustaining 1 less g than it should at higher speeds (above 600), if one of yall whos better at this can confirm would be great help.
here is image from manual for reference for your own testing
conditions are a plane with 2 R-27R and 2 R-73 and 50% remaining fuel after a typical refueling (tanks 1 and 4 filled in a typical refueling) or roughly 1860kg worth of remaining fuel
8.2.1. Предусмотрены следующие варианты заправки самолета топливом: полная, основная и частичная. При основной заправке заправляются только баки № 2 и 3. При полной заправке заправляются все баки. Заправка баков производится закрытым способом – под давлением или открытым – через заливные горловины. При частичной заправке бак № 2 заправляется открытым способом полностью (контроль визуально) или не менее 3400 (контроль по топливомеру). Топливо из баков вырабатывается через расходный отсек бака № 2 автоматически. Порядок выработки топлива регулируется системой топливоизмерения СТР7-2АК.
if thats the case that works out to ~2610kg internal fuel + 2 R-73 + 2 R-27R to get an accurate test you’d need to do this with the J-11 since thats an SK or add an additional 570kg of internal fuel to the Soviet Su-27 to account for the increased mass of the J-11
this is what im getting in the J-11 with 2820kg internal fuel and 2 R-73 but no R-27Rs so this configuration is actually lighter than the what the manual specifies yet it still seems to underperform
I have trouble keeping a perfect altitude since im doing this on a laptop but if anyone with R-27Rs unlocked would like to give it a go it would be appreciated
But the lower right corner also says ‘для другой массы ηуф = ηуст. вир. • 20000 / mф’, which means for other weights, maximum allowed load factor can be calculated by multiplying 20000 / current mass. This could be an indication that the mass used in drawing the graph is 20000 kg.
since I lack R-27Rs the total weight in my example is 200kg lighter however considering it appears to underperform even in a lighter than should be configuration isnt a good sign
in full real controls in the J-11 2 R-27R on the wing (nothing else) at 3000m try to rate is the ideal test since thats the closest to the manuals parameters, use http://127.0.0.1:8111 ofc, would be big help :)
