摘要
根据稳定性理论，对某型高速飞机的惯性耦合进行了初步研究，首先，对飞机的滚转－偏航耦合和滚转－俯仰耦合的机理进行分析。然后，在不影响问题本质的前提下提出了一些假设条件，将研究惯性耦合的六自由度全量方程进行简化，求出急滚稳定性判据。以某型机为例，计算出其惯性耦合特性，用急滚稳定性判据进行了分析，并进行了验证。
Based on the theory of stability,the inertia coupling characteristics of an highspeed aeroplane are studied.An important conclusion is obtained that this type of aeroplanehas not only the roll-yaw coupling in the zones of high altitudes and big Mach number butalso the roll-pitch coupling in the zones of low altitudes and subsonic speeds.Then thecauses of this phenomenon are analysed and calculation is done in order to proved theconclusion.
