摘要
针对某鸭式布局的电动无人汽车飞机,理论计算了它的升力与阻力系数,讨论了它的升阻特性;同时,将计算结果与涡格法气动软件AVL的模拟结果进行了对比,以确保所设计汽车飞机气动性能的合理性。研究表明,本文的汽车飞机设计方案是成功的,飞机具有良好的升阻特性。
With one unmanned duck-type flying car as investigated object,the lift and draft coefficients are calculated and discussed on theory.In order to ensure the rationality of the flying car on aero-dynamics properties,the calculated results are further compared with those obtained by AVL,an eddy-lattice-method based aero-dynamics software.It is shown by flight-test that the present flying car is successful on design,and is excellent in lift and draft properties as well.
