【摘要】 针对一对鸭舵的制导炮弹,提出采用模糊综合评判方法进行气动布局参数设计。选用一套气动力快速估算方法计算了制导炮弹的气动特性,分析了气动布局参数对气动特性的影响;建立了有控弹道模型,并在一定控制模式下对有控弹道特性进行了分析;综合考虑有控弹道设计的各项指标,应用模糊综合评判模型对气动布局参数进行了合理设计。算例结果表明,该设计方法具有良好的实用性和通用性。更多还原

【Abstract】 Focused on the guided projectile equipped with a canard,the fuzzy comprehensive evaluation method(FCEM) was proposed to design the aerodynamic configuration parameters.The aerodynamic characteristic of guided projectile was calculated by a set of aerodynamic fast algorithm.The influence of parameters on the aerodynamic characteristic was analyzed.The controllable trajectory model was established.The controllable trajectory characteristic was studied under a certain control mode.Considering several factors,the design of aerodynamic configuration parameters was done by using FCEM.Example results show that this method has practicability and generality.更多还原
