| Abstract: | Research and simulation analysis of route planning of stratospheric airships were carried out in the paper.Firstly,considering the stratospheric airship’ s flight characteristics,its motion equations and wind models were established.Then a cost function of the airship flight energy consumption was formulated based on proper assumptions.Finally,the approach of genetic algorithm was presented for searching optimal route.The example numerical simulations showed that the genetic algorithm was able to quickly,stably converge to the optimal solution,and it was an effective approach for solving this kind of problem;the cost function made in this paper could reflect airship’ s flight characteristics and it was sensitive to the wind environment. |
