| 摘 要： | 分别运用涡流理论和动量理论对纵列式双旋翼直升机建立了两种飞行动力学非线性数学模型并完成配平计算,这两种方法得到的配平结果和参考的实验数据较吻合,所建模型是后续进行稳定性导数和稳定根计算的基础.

| Abstract: | Two mathematical models for determining the trims of a tandem helicopter using two techniques are built separately in this paper,one among which is based on the momentum theory and the other is based on the rotor vortex theory.And the comparison of trim analysis figures has shown a good agreement with the referenced test results,and the models are the basis of analysis for determining derivatives. |
