Abstract

Recent studies have pointed out that conventional lifting rotors in forward flight have efficiencies far lower than the optimum efficiencies predicted by theory. This paper presents a closed-form optimization of induced power with finite-state models is expanded to obtain the results for pressure and induced velocity distributions for a rotor in forward flight. Results for induced power efficiency (IPE) variations in forward flight and for different conditions are presented.
