摘要：In the past two decades,the world’s unmanned aerial vehicle(uav)industry has developed *** kinds of uavs have been used in military and civilian *** on the characteristics of uavs and the development of aerodynamics,this article analyzes the development of aerodynamic optimization design and dynamic numerical simulation technology,then lists engineering *** aerodynamic optimization design and dynamic numerical simulation have greatly shortened the uav design period and reduced the research and design *** two methods gradually replace traditional methods such as wind tunnel test.
