倾转旋翼机推进系统特点及关键技术分析

Analysis on the Characteristics and Key Technology of Propulsion System of the Tilt-rotor Aircraft

推进系统直接影响倾转旋翼机研制成败,是其设计成功与否的关键。分析国外三种在役和在研的典型倾转旋翼机,结合不同种类倾转旋翼机需求提炼三类推进系统特征和结构特点。在此基础上解析并评价倾转旋翼机推进系统的四类关键技术,提出装备发展和技术研究建议,综合分析认为推进系统技术是中国倾转旋翼机发展的重要瓶颈之一,需要重点研究并予以突破。

Propulsion system directly affects the success or failure of the development of tilt-rotor aircraft,which is the key to the success of its design. Three typical tilt-rotor aircrafts in service or under research abroad are analyzed,and the characteristics and structural features of the three types of propulsion systems are refined combined with the needs of different kinds of tilt-rotor aircraft. On this basis,four key technologies of propulsion system of tilt-rotors are analyzed and evaluated. Suggestions on equipment development and technology research are put forward. The comprehensive analysis shows that the propulsion system technology is one of the important bottlenecks in the development of tilt-rotor aircraft in China,which needs to be studied and broken through.
