If you're light, you will over-G or your airspeed will increase uncontrollably.)" Keeping all of the above in mind. As you said, " Go faster than 850 km/h - and your turn suffers again (If you're heavy, the total drag hurts your turn rate. ![]() There is nearly a 300 m difference in the turning radius at 850 Km/hr. The Corner speed that i have taken account as 540-650 is because it is easier to sustain those speed at moderate to high loading and the turning radius to be as low as possible. Ill try and find the perfect balance between all of them !! Edited Decemby =ITGC=Verticle Charlie And further as you have said there cannot be just a single figure for the Corner speed.A lot of factors have to be taken into account ( Height, radius, Speed, Loading,turn rate etc). But in any case i do see what you mean, and the manual will be updated after we test it out. ![]() I would rather sustain that 600 Km/hr and maintain my short turn radius than be at 800 + and keep on Over G and be practically blind or be at near blackouts. If you're light, you will over-G or your airspeed will increase uncontrollably.) Edited Decemby Stuge Go faster than 850 km/h - and your turn suffers again (If you're heavy, the total drag hurts your turn rate. Go slower than 600 km/h - your turn rate starts hurting. This is very different from the F-15 which indeed benefits from riding the "edge of blackout" at corner velocity. The graph would suggest ever increasing turn rate with increasing airspeed until max G is hit, putting the "corner" speed at around 850 km/h for an 8 G turn (which is the most you can sustain without blacking out)īut my experience and the Su-27 graphs I've seen tell that both of these claims are false - there is indeed a "plateau" of sorts, which evens out the performance in the 600-800 km/h area meaning there is no "single best speed" to turn at, but instead a fairly constant turn rate across this speed range. For a Sukhoi it’s somewhere around 540- 650 Km/ Hr. In fact, your manual has another claim that contradicts this graph: "Use corner speed to your advantage. Look at the graph description in the manual: it says "typical turn rate plot of a modern fighter", not specifically Su-27 plot. We will however, test with your chart as well !! Thanks. Please let me know if you find any difference. With regard to the chart, it is directly from the DCS manual for 27 and seems consistent with flight performance. ![]() Feels good when pilots like you and frostie take out the time to read it. Hey Stuge !! thanks a lot for going through it.
