摘要
为了研究鸭舵式修正机构的气动特性,对几种不同形状、不同面积鸭舵的阻力、升力、各项力矩进行了分析,提出了基于鸭舵修正机构的修正方法,建立了舵片实现减旋后的弹道模型,并分析了不同形状舵片在相同时间点进行弹道修正后的修正能力。分析结果表明在保证较好舵翼气动外形的基础上,尽量选择大展弦比的舵翼,这样能更好的提供较大升力和偏航力。
In order to research on aerodynamic characteristics of canard rudder trajectory correction mechanism, drag, lift, moment of ca-nard rudders with different shape and area were analyzed, the correction method for canard correction mechanism was proposed. The trajec-tory model of reduced gyration was built and the correction capability of rudders with different shape given trajectory correction at the same time was analyzed. The results show that rudder and wing with larger aspect ratio should be used for better lift and yaw on the premise of moderate aerodynamic configuration.
