New energy consumption model for rotary-wing UAV propulsion

Accurate and convenient energy consumption models (ECMs) for rotary-wing unmanned aerial vehicles (UAVs) are important for UAV communication designs. Existing models are complex and inconvenient to use. In this letter, a simple and easy-to-use model with closed-form expression as a function of the initial velocity, acceleration and time duration is derived. Using this model, the UAV flight control parameters, such as polling force and tilt angle, are analyzed in analytical form. Numerical results show the validity and reliability of the proposed model.
