基于叶片飞断的航空发动机机匣包容性试验研究进展
Research Advances in Blade-off Containment Test of Aero-engine Casing
航空发动机机匣包容性设计是保障飞行安全的核心要素。为了保障飞行安全,机匣须具备防止断裂叶片穿透机匣导致二次破坏的能力,包容性试验是检验机匣是否具备良好包容能力的有效途径。从包容性定义和条款要求出发,详细介绍了打靶试验、部件包容性试验以及整机包容性试验研究进展,阐述了部件包容性试验涉及的数值仿真、叶片定速飞脱、温度标定与高速摄像等关键技术的研究现状。归纳总结了当前的研究不足,未来研究应着重构建服役工况下的部件级试验平台和建立科学规范的整机级包容性验证标准,研究对提升航空安全防护水平具有重要工程价值。
Aero-engine casing containment design is a core element of flight safety. To ensure flight safety, the casing must have the ability to prevent secondary damage from broken blades penetrating the casing. The containment testing is an effective way to verify that the casing is well contained. Starting with containment definitions and regulatory requirements, the research advances of ballistic impact test, component containment test and engine containment test were introduced in detail. The current research status of the key technologies involved in the component containment test, such as numerical simulation, blade separation at predetermined speed, temperature calibration and high-speed camera were described. Furthermore, the current research limitations were summarized. The future research should be focused on building component level test platforms under service conditions and establishing scientifically standardized standards for engine containment verification. The study has important engineering value for raising the level of aviation safety protection.
