摘　　要：现代飞机设计变化 ,增大了喷气战斗机出现惯性交感的可能性 ,致使某些飞机在高滚转速率下完全失稳。这种现象的数学分析通常是相当困难的。为此 ,本文利用简化线性分析法研究了惯性交感的影响因素和灵敏度 。As a reasult of the design changes of modern aircraft, the possibility of inertial cross-coupling for the jet fighter increases, Some aircraft are completely unstable at high roll rates.A mathematical analysis of this phenomenon would generally be considered quite difficult. For the purpose, In this paper, using the simplified linear analysis to study the effect factors on inertial cross-coupling and the susceptibility of the aircraft to inertial cross-coupling. Also from the computer simulation was determined the aircraft parameters that affect stability and was provided the inertial cross-coupling control system by adding yaw and pith rate feedback to artificially stabilize aircraft.
