摘　　要：针对高速履带车辆空气阻力系数不准确、影响机动性能计算的问题,开展了履带装甲车辆空气阻力系数测试研究。利用相似性理论,对多种履带装甲车辆微缩比例模型开展风洞试验,获得不同类型履带装甲车辆的空气阻力系数值。结果表明:履带装甲车辆空气动力学设计中,主战坦克空气阻力系数可选择0.92,自行火炮类型车辆空气阻力系数可选择0.99,步兵战车等类型车辆空气阻力系数可选择0.83;试验结果为车辆机动性精确计算提供了工程指导。A test research on the wind drag coefficient of tracked armored vehicles is carried out for the problem about the inaccurate wind drag coefficient of high-speed tracked vehicles affecting the calculation of maneuverability.Based on the similarity theory,a series of wind tunnel tests were made for the miniature scale models of armored vehicles.The wind drag coefficient values of different types of tracked armored vehicles were obtained by processing the test data.The results show that,in the aerodynamic design,the wind drag coefficient of 0.92 can be selected for the main battle tank,0.99 can be selected for self-propelled artillery vehicles,and 0.83 can be selected for infantry fighting vehicles.The test results provide engineering guidance for the precise calculation of vehicle maneuverability.
