Abstract

The paper describes the methods to estimate power required by two seater helicopter at three flight conditions: hovering, vertical climbing and forward flight. Factors that affect the power required by the helicopter include induced velocity along the rotor blade, various altitudes, horizontal force due to the fuselage and others are discussed in this paper. Methods analyzed in this study to estimate the power are momentum method, blade element method and combined method. The initial specification of the helicopter was done by studying the present helicopter configuration in the market. All related data were then plotted against gross weight. The study on weight estimation was done according to the Prouty method and based on some assumptions. The helicopter specification as studied in this paper was found closely similar to the specification of existing helicopter in the market. Keywords : Power estimation, gross weight, develop programming, preliminary helicopter design
