三、副翼-差动平尾组合横滚操纵系统气动设计问题 1.对差动平尾偏航力矩问题的对策和技术措施 (1)平衡差动平尾偏航力矩的“方向舵交联(ARI)”方案及其问题采用差动平尾的现代飞机普遍地采用方向舵对横向操纵的交联(ARI)来平衡其偏航力矩,如表1所示。为此从设计观点出发,分析了现代歼击机采用方向舵交联的多种原因和目的,研究了有关品质、指标、检查方法、设计准则、交联规律选择、交联量计算等问题。详细设计计算了本机采用方向舵交联的具体方案后发现如下技术难点: ①需采用变交联比方案,实现难度大,代价大。如前所述,本机差动平尾所产生的
Third, the aileron - differential flat-tailed combination of roll control system aerodynamic design problems 1. Differential leveling tail yaw moment countermeasures and technical measures (1) Balance differential tail-tail yaw moment "Rudder Crosslinking (ARI) Scenarios and Problems Modern aircraft that employ a differential flat-tail commonly use rudder-to-transverse cross-linking (ARI) to balance their yaw moment as shown in Table 1. Therefore, from the design point of view, the paper analyzes the reasons and purposes of the modern fighter plane using the rudder cross-linking, and studies the related problems such as quality, index, inspection method, design criteria, selection of cross-linking rules and calculation of crosslinking amount. The detailed design and calculation of the specific scheme of this machine using the rudder cross-linking found the following technical difficulties: ① need to use the variable cross-linked ratio scheme, the realization of difficult, costly. As mentioned earlier, this machine produced by the end of the flat tail
