【Abstract】 In this paper, transition Reynolds number and transition distance in the outside flow field of four kinds flying vehicles are calculated according to the flow tube method, based on the approxi-mate shock relation, the pressure distribution on blunt-nosed cones, the state equation of equilibrium gases, the formula for calculating boundary layer thickness, and the transition criterion etc, the Reynolds numbers distributions are presented along the surface of blunt-nosed cones made of Refrasil, Carbon guartz, Carbon-Carbon, and the results of calculation for flying vehicles and models are analysed and compa-red.更多还原
