The total flight time is also fixed for the problem. Simulation results show the accuracy of the method. Increasing the midway points for linearization, increases the accuracy of the solution, which this, in turn, depends on the total flight time.}, keywords = {............................}, url = {https://jast.ias.ir/article_51619.html}, eprint = {https://jast.ias.ir/article_51619_d39cf34741e12bce45028046ece90594.pdf} }
