Energy balance is the core factor and also one of the most difficult points of the design of solar powered aircrafts. Based on solar radiation model, energy principle and typical flight profile of solar powered aircrafts, this paper conducts research on energy balance modeling for solar powered aircrafts. Both takeoff-climb-cruise energy balance model and the whole day duration flight energy balance model are constructed based on the flight profile and energy requirement. Energy calculating formula for each time phase is presented, and multiple cases of glide are discussed. The energy balance models are validated through an analysis example.
