A Flight Performance Analysis Method On Subsonic Airplanes And Its Application On UAV

This paper made some programs which are from Pro.Smetana.F.O.’s 《Flight Vehicle PerformanceAnd Aerodynamic control》into a systemic software on flight performance with the name of FVPAAC.In addition a method of flight performance analysis was proposed with the process of3D solidconfiguration reproduction, aerodynamic characteristics analysis and flight performance analysis. Thispaper reconstructed an accurate3D configuration of Predator C UAV, with the theory of3D solidconfiguration reproduction from respective images. With the3D configuration and the CFD theory,this paper computed and made an analysis on the aerodynamic characteristics of the Predator C UAV.After that, the flight performance including the stable performance at different altitude, theperformance of climbing and the performance of taking off of the Predator C was computed by theFVPAAC software with the outcome of the aerodynamic characteristics. At the last chapter of thispaper was the stealth characteristics analysis of the Predator C UAV.
