Schirmer Wing
Thinking about doing a team schirmer wing on my F22. Does anyone have one on theirs? Haven't seen it on an f22 yet. I've read that it's basically the same as the m235ir wing just with smaller uprights and end plates…. Dropped photos of the wing and my build for reference

Here's my wing. Had a local shop install for 200$. With most of them you have to have plates/supports in the trunk to keep the wing stable or else it'll be flappy as hell. Most kits come with support plating, if not then a shop would have to weld it (costs a bit more). Good luck, should only take a few hours for install.

Has anyone seen data on downforce for the GTS wing when paired with the original "low" M4 mounts compared to the "high" M240iR Evo mounts? Intuition says getting it higher in cleaner air should be better, but how much better are we talking?

A wing of that size in free air (about 0.25 square metres by the looks of it) will only generate about 140N (31lbf) of downforce at 30m/s (67mph) or 390N (88lbf) at 50 m/s (112mph).
The difference in being in free air compared within the trailing flow off the rear window is probably only about 10%, so perhaps 40N (9lbf) at 50m/s (112mph). The main thing to adjust is the angle of incidence to the flow to ensure it doesn't stall if the air flow direction is too acute to the wing leading edge. Another consideration is that a smaller gap to a surface can actually accelerate flow, increasing the velocity across the aerofoil. Only a CFD simulation or wind tunnel measurement will give an accurate result. Generally two bags of sand in the trunk will be more beneficial to rear axle down force than a wing of that type and position in normal road or light track use. |
