摘　　要：用模型风洞对新概念车在不同横摆角下纵对称面上压力系数、整车气动力和气动力矩的变化以及纵对称面尾部流态分布进行了试验研究。通过和同等试验条件下典型汽车的气动性能对比,由于新概念车良好的外部流线,其气动性能明显优于典型汽车。An experimental study on the aerodynamic characteristics of New Concept Car is conducted by model wind tunnel test, covering the pressure coefficient and wake vortices on longitudinal symmetry plane, as well as aerodynamic forces and moments under different yaw angles. The results are compared with that of a typical common car under same testing conditions, which show that the New Concept Car has better aerodynamic characteristics than common car due to its ideal streamlined bodv.
