摘　　要：根据倾转旋翼机的布局特点,建立了包含旋翼、机翼、垂尾、平尾(含舵面)和机身的气动模型及全机飞行力学模型。对不同重心位置模型进行配平分析,在配平的基础上进行了线性模型的提取和分析,给出倾转旋翼机重心包线的计算方法。最后以XV15倾转旋翼机为算例进行不同重心位置的配平、稳定性分析和重心包线计算。结果表明该方法合理有效。According to the features of the layout of tilt rotor aircraft, this paper established flight dynamics model includes rotor, wing, fin and tail plane （including elevator） and fuselage dynamic model. Trim analysis was carried out on the model, extraction and analysis of linear model was cartied out on the trim, the center of gravity envelop calculation method of the tilt rotor aircraft was given. Finally, the trim, stability analysis and center of gravity envelope calculation was carried out with the example of the xv15 tilting rotary rotor aircraft. The results show that the method is reasonable and effective.
