In order to study the temperature distribution characteristics of near-space hypersonic vehicles, the numerical calculation method was adopted to simulate and analyze the aerodynamic heating effect of hypersonic vehicles in this paper. The simulation process consisted of model establishment, mesh division, and CFD numerical calculation. Based on the simulation results, the temperature distribution characteristics of hypersonic vehicles and the influence of flight speed on the body temperature were analyzed. The results show that hypersonic flight will increase the body temperature significantly. The temperature at the stagnation point of the warhead can reach up to 2185K, and the temperature in other areas along the axis of the projectile gradually decreases. As the flight speed increases, the temperature of the vehicle body rises rapidly. When the flight speed is at 6.58Ma, 8Ma, 9Ma, and 10Ma, the temperature at the stagnation point of the missile body can reach 2185K, 3172K, 3792K and 4772K respectively
