Based on the current battery and motor characteristics, the mathematical model of the energy and power system for the electric helicopter is established respectively. Three energy schemes that satisfy the electric helicopter are proposed, and a set of overall parameter selection and optimization methods are designed for the conceptual design of the electric helicopter. Combined with the mission profile Demand for the choice of three parameters of the electric helicopter to start the overall parameter selection and sensitivity analysis. By the current level of battery technology development, electric helicopter long-haul performance compared with the fuel-powered helicopter has a big gap. Through parametric sensitivity analysis, the electric helicopter has different design features from the fuel helicopter. The electric helicopter should be designed with the characteristics of power and energy system.
