A technique of vaying lip simulating total pressure distorted flow field has been investigated experimentally.The effects of the various geometric parameters of the lip on the total pressure distribution and the turbulence of the total pressure fluctuation are analysed

some rules have been obatined.The relations of the total pressure recovery and the mean turbulence to the mean Mach number for the axisymmetrical lip of various shapes are also presented.Therefrom the approach and the concept for simulating the real total pressure distorted flow field are deduced.Moreover

two kinds of the real total pressure distorted flow fields are simulated.
