Optimization of Hover-to-Cruise Transition Maneuver Using Variable-Incidence Wing

Abstract

A = disc area of the propeller D = drag g = acceleration due to gravity J = cost/objective function L = lift L=W = lift-to-weight ratio m = mass of the aircraft T = thrust Tmax = maximum thrust T=W = thrust-to-weight ratio T=W max = maximum thrust-to-weight ratio u = horizontal velocity u = control variable vector ut = terminal horizontal velocity V = freestream velocity wi = ith weight coefficient vt = terminal vertical velocity W = weight w = induced velocity aft of the propeller x = horizontal acceleration yi = altitude at ith discretized calculation instant z = vertical acceleration fus = fuselage and inboard wing angle of attack prop = angle of attack of the propeller wing = outboard wing angle of attack _ wing = rate of change of outboard wing angle of attack = flight-path angle = air density _ = rate of change of variable , d dt
