Flutter of Delta Wing under Aerodynamic Heating

  • Received Date: 11 Jul 2007
  • Publish Date: 25 Feb 2008
  • From the characteristics of aerothermoelasticity,the effects of temperature in aerodynamic heating on the mode of a delta wing and the characteristic of its flutter were researched.The temperature distribution of the delta wing under aerodynamic heating was investigated with flux balance equation,and the influences of temperature on the natural dynamic characteristics of two typical supersonic delta wing models were analyzed with FEM(finite element method).The aerodynamic load was calculated with the second order piston theory of supersonic aerodynamics,and the flutter equations were solved with the P-K method.The research results show that aerodynamic heating will result in changes in the natural dynamic characteristics of the models,so the flutter velocity of the delta wing will decline sharply.
