Abstract： Synthetic analysis is conducted to the wind tunnel experiment results of zero lift drag coefficient and lift coefficient for large aspect ratio winged rigid body. By means of wind tunnel experiment data, the dynamics model of the zero lift drag coefficient and lift coefficient for the large aspect ratio winged rigid body is amended. The research indicates that the change trends of zero lift drag coefficient and lift coefficient to Mach number are similar. The calculation result and wind tunnel experiment data all verify the validity of the amended dynamics model by which to estimate the zero lift drag coefficient and lift coefficient for the large aspect ratio winged rigid body, and thus providing some technical reference to aerodynamics character analysis of the same types of winged rigid body.
Key words： winged rigid body; zero lift drag coefficient; lift coefficient; wind tunnel experiment; dynamic characteristics

摘要:对大长径比带翼刚体的零升阻力系数和升力系数的风洞试验数据进行了综合分析， 利用风洞试验数据修正了带翼刚体升力系数和零升阻力系数的动力学模型。 研究结果表明， 大长径比带翼刚体的零升阻力系数和升力系数随马赫数的变化趋势基本相似， 数值计算数据与风洞试验数据都验证了修正后的动力学模型对于估算大长径比带翼刚体的升力系数和零升阻力系数是可行的,为同类型带翼刚体的空气动力特性分析提供了技术参考。
