Aircraft Conceptual Design Optimization Considering Fidelity Uncertainties

ARv = vertical tail aspect ratio ARw = wing aspect ratio CD;0 = parasite drag coefficient CL;max = maximum lift coefficient hcr = cruise altitude Ix = moment of inertia about x Iy = moment of inertia about y Iz = moment of inertia about z k = induced drag constant Mcr = cruise Mach number Me = aircraft empty mass Mf = fuel mass Mg = aircraft gross mass Mpl = payload mass Npax = number of passengers nfuse = fuselage configuration number R = range Sh = horizontal tail area STO = takeoff distance Sv = vertical tail aspect ratio Sw = wing area Tsl = sea-level thrust Va = approach speed Vs = stall speed xcg = longitudinal center of gravity w = wing dihedral angle "Me = empty mass error ratio "SFC = specific fuel consumption error ratio "Tavail = available thrust error ratio "Treq = required thrust error ratio h = horizontal tail aspect ratio w = wing sweep angle h = horizontal tail taper ratio v = vertical tail taper ratio w = wing taper ratio
