Abstract

The optimal takeoff performance of a vectored thrustV/Stol aircraft is analysed by a nonlinearprogramming method based on a sequentialunconstrained minimisation technique. The study isfocused on ship operations which involve VTO andski-jump STO launches. Once the optimal rampgeometry is determined, minimum-fuel andminimum-time problems are solved. The optimalcontrol sequences are evaluated and the effects ofship motion and atmospheric winds are discussed. Amicroburst encounter following an STO launch is alsodealt with in terms of aircraft survival.
