Isa Speed Testing Of All Fighters In Game

[Sgt_Joch]

 

 

84. Before starting the turn, stabilize the aircraft in level flight at a speed of 320-340 km / h . This same speed must be maintained when making a turn with twist 65-70° . Making a left turn the plane tends to lower the nose, while with the right turn tends to lift. The plane is stable making turns and passes easily from one side to another. If you are in a turn and you pull the stick in excess, and the speed of 270-280km / h is reached, the aircraft becomes unstable; if you keep pulling the stick, the aircraft wing drops. When you pull the stick in excess and lose speed (the characteristic symptom is when the plane starts to shake) should push the stick forward and put the aircraft in level flight. If the plane goes into a spin, is carried out according to standard procedure.

 

 

 

I have been spending most of my "flying" time in BoS with the Yak and the "accelerated stall" is modeled. I have not tested the exact parameters, but typically at around 350 KMH, if you pull too much on the stick during a turn, you will hear the rumble of the impending stall and when the stall occurs, whatever wing is closer to the ground will drop. This will happen even if you are very smooth and careful with your movements. However, it is easy to avoid the stall if you immediately release stick pressure as soon as the wing starts to drop.

 

I will have to check if the other factor, i.e. where the nose is during the turn is also modeled. I have noticed that it is hard to keep a turn level in the Yak, but that may just be due to lack of practice.

Great job, Celestial! 

 

I'm wondering about one thing: now we test all the speeds in the freezing cold of Russian winter. Cold air is known to boost performance in this game. Can't it be the reason of overperformance? IF we fix all speeds now, won't they all be too slow once we get the Summer map?

I believe Celestiale used that map editor to make ISA conditions which should remove the cold boost effect.

Actually power output and prop efficiency on the Klimov as in the Yak are better at 2550 rpm then at 2700 rpm, unless above full throttle altitude, where the supercharger performance is better with higher rpm. Therefore, in real life, higher speeds were obtained with 2550 than with 2700 rpm at low altitudes. Also, the June 1942 test is with a series 69 aircraft which is what we've got in game.

From my testing ingame full throttle 2700 rpm performance is always better than 2600 rpm at all altitudes.
