Hi,
I want to work out an approximate corner speed.
It was a long time ago and a vague memory but did I read a simple formula of stall speed x 2.45 ?
That's correct. It's the square root of the wing loading in "G"s times the indicated stall speed at your weight and altitude. For corner speed it's 6 G because that's when we black out so it's our max sustainable G load. The square root of 6 is 2.4494 hence 2.45. If you are at a weight and altitude where you stall at 100 mph in straight and level flight then your corner speed is 245.
I believe you can also approximate the stall speed for any other wing loading the same way. So if you wanted your stall speed for cornering at 3 G you get 173 mph, given the same 100 mph straight and level stall as the above example.
Since stall speed is linked to wing loading it also follows that at 0 G you can't stall. Since you aren't creating lift there is no lift to be disrupted.
