PatMc Posted December 16, 2013 Share Posted December 16, 2013 DH2, I think you're refering to the DH Hornet, Mosquitos all had same rotation props both sides. OTOH the Lochheed P38 props rotated outwards from the cockpit. Quote Link to comment Share on other sites More sharing options...

I'm with Ben - without aerofoil data - and the Cl curve - I don't see that this is anything more than just a guess and as "stall speed" is a rather ambiguous parameter not a particularly useful guess surely? BEB Stall speed discussed here: **LINK** (or check out Martin Simonds et al on flow separation) The calculator at the bottom of this page lets you figure out that WebOCalc assumes a CL of about 1. **LINK** It is useful as you can run sensitivity analyses to estimate how variations that airfoils with CL vastly different to 1 will impact your model’s estimated performance.
