Centerline-thrust multi: effect on Vspeeds?
I'm curious how a centerline thrust twin-engine airplane design would alter the takeoff (V1, Vr, V2) and approach/landing (Vref) speeds -- if at all -- both from an engineering and regulatory standpoint.
It strikes me intuitively that a centerline-thrust twin design might move certain speeds closer to stall, without having to worry about asymmetric thrust Vmc, critical engine, etc, and could thus improve the takeoff and/or landing distance performance vs the exact same aircraft with asymmetric thrust. But I'm not clear how this would pan out in any detail.
Any thoughts?
