新材料和新结构的开发使用是航空发动机减重的一个主要技术途径，纤维增强钛基复合材料制备的整体叶环结构具有明显的减重优势。以SiC(f)/TA12整体叶环试验件为例，分别从结构、强度、工艺等方面阐述了整体叶环设计技术。利用ANSYS有限元软件进行数值模拟，并采用最大应力准则和平均周向应力准则评估了整体叶环试验件的破裂转速。通过旋转试验初步验证了整体叶环的减重效果和强度计算方法，并对今后的研究方向进行了展望。
新材料和新結構的開髮使用是航空髮動機減重的一箇主要技術途徑，纖維增彊鈦基複閤材料製備的整體葉環結構具有明顯的減重優勢。以SiC(f)/TA12整體葉環試驗件為例，分彆從結構、彊度、工藝等方麵闡述瞭整體葉環設計技術。利用ANSYS有限元軟件進行數值模擬，併採用最大應力準則和平均週嚮應力準則評估瞭整體葉環試驗件的破裂轉速。通過鏇轉試驗初步驗證瞭整體葉環的減重效果和彊度計算方法，併對今後的研究方嚮進行瞭展望。

Development and application of new materials and new structures in aero-engine is one of the major technical ways to reduce engine weight. The weight advantage of bling structure with continuous fiber reinforced titanium matrix composites has been verified. Taking a SiC(f)/TA12 bling specimen as an exam?ple, the structure design, strength analysis and processing of bling are discussed. A numerical simulation is made by ANSYS. The burst speed of bling has been estimated using maximum stress criterion and circum?ferential average stress criterion. Effects of weight reduction and methods of strength analysis have been ver?ified by rotating tests. The research direction in the future has also been discussed.
