Research on the Influence of Flight Altitude on the Aerodynamic Characteristics of Su-27 Fighter Aircraft

Authors- Son Nguyen, Truong Thanh Nguyen, Khuat Van Huy

Abstract-The article focuses on studying the influence of flight altitude on the aerodynamic characteristics of the Su-27 fighter. The research was conducted on the basis of applying SolidWorks software to build a 3D model of the aircraft, combined with the Fluent module of Ansys software to simulate and calculate the changes in aircraft characteristics such as drag coefficient, lift coefficient and longitudinal moment coefficient. From there, some recommendations are given to users to improve flight performance and enhance flight safety when the aircraft changes flight altitude.
