双机斤斗飞行中上赶下掉问题的研究

简述了飞机斤斗飞行的基本运动关系和操纵动作要领。以双纲斤斗为例，指出了双机编队复杂特技科目中存在着突出的上赶下掉现象；并阐明了上赶下掉现象形成的原因及其特点。重点探讨了保持双机斤斗编队距离的操纵方法、基本原理和具体修正计算式。最后，为保证飞行安全，分析了双机斤斗飞行易出现的主要偏差、特殊情况、修正方法以及应注意的有关问题。

Research on the formation distance in the twin-plane loop

First it analyses the basic movement relation and states control actions shortly in the single plane loop. Secondly, taking twin plane loop as an example, it points out the distinctive phenomenon that formation distance becomes nearer and farther while flying up and down lies in the complex aerobatics subjects in the twin plane formation and then it explains the forming reason of this phenomenon as well as its character. Thirdly, it emphatically make a deep survey on controlling methods keeping twin plane loop formation distance, basic principles and specific revising formula. Lastly, in order to ensure the safety of flight, it analyses easily appearing main deviations, particular conditions as well as its revising methods in the twin plane loop and furthermore it put forward some noticeable problems in the twin plane loop. The paper lays a emphasis on the introduction and analysis of the practical controlling character, besides it also has some certain theoretical guiding function to the complex twin plane aerobatics safety of flight.
