Three-Dimensional Reconstruction And Aerodynamic Characteristic Analysis Of The Business Jet G150

With the development of economy, the business jet will be more and more popular. There is noresearch and design for our own business jet in china now. The Study of foreign classic business jetGulfstream G150, is of great research value.Take G150as the research object,this paper reconstructed its3d outshape according tomulti-anglepictures reconstrction theory.With the advancement of aerospace technologycomputational fluid dynamics(CFD)technology has developed rapidly,and it has been applied widelyin the field of aircraft design.Now the CFD technology has become a brand-new method in the aircraftaerodynamic design.This paper introduced the method to mesh aerodynamic shape, calculated and analysed theaerodynamic characteristics of G150in the cruise state. At the same time, calculated and analysedtwo-dimensional aerodynamic characteristics of G150in takeoff and landing configuration. Estimated thelift coefficient and drag coefficient increment of G150when high-lift device is opend.Flight performance is an important indicator in evaluation of a business aircraft. With itsaerodynamic characteristics analyzed and flight performance furtherly evaluated by the numericalsimulation of its outshape using CFD.
