Abstract
Sections 1 through 3 of the full paper explain the determination of the effects mentioned in the title and then propose an optimization scheme based on such determined effects; we believe that both our determination and optimization scheme mentioned above are effective. The core of Sections 1 through 3 consists of: (1) we establish the mathematical model for the motor-propeller propulsion system of HALE solar UAV; (2) we analyze the relationship between flight conditions and output thrust of the distributed propulsion system; (3) we linearize the model, and, based on the study of flight quality of large aspect-ratio solar UAV, deduce the effects of distributed propulsion system on lateral flight quality of the solar UAV, which are altered by the distribution and control scheme of propulsion system; (4) for the purpose of long flight endurance, we propose an optimization scheme; (5) simulation results, presented in Figs. 5 through 7, and their analysis show preliminarily that our optimization scheme is indeed effective.
