直升机技术发展的若干问题

讨论了直升机技术的发展及现状。首先，简要介绍了直升机技术研究的主要内容，然后讨论了其中的几个方面，包括：旋翼载荷预估、旋翼气动弹性分析、复合材料结构动力学、旋翼噪声预估。讨论着重于分析模型，分析方法和参数敏感性，借以反映当前直升机技术研究的现状，并探索进一步的研究方向。此外，文中还强调了分析预估与试验结果吻合关系分析的重要性。

Some Aspects of Development of Helicopter Technology

Presents the state-of-the-art and the development of helicopter technology.First, the main content of helicopter technological research is introduced in brief. Then some aspects of these,such as prediction of rotor airload,aeroelastic analysis of rotor,composite structure dynamics and rotor noise are discussed with emphasis on analytical models,analytical methods and parameter sensibility analyses in order to predicte the state-of the-art in helicopter technological research and possible research trends. The paper also lays stress on the importance of correlation analysis between analytical prediction and test results in helicopter technological research.
