Part I of this complementary article is concerned with the design, development and commissioning of a novel instrumented scaled down test rig to examine the dynamics and containment of a released blade during blade shedding (blade out) incidents in aviation gas turbine engines. The scaled down fully bladed disk is designed using non-dimensional parameters derived using Buckingham’s dimensional analysis technique. These parameters are enforced to ensure dynamic equivalency of the scaled down model and a realistic full size gas turbine engine. The rotor with drive system is encapsulated in a thick protective casing to contain all fragments within the confines of test rig and ensure safety of operation. The test rig is equipped with a high speed camera and numerous sensors interconnected via data acquisition system to two processors for data collection and data management. The purpose is to measure the released blade trajectory, its multiple interactions with the trailing blades, containment within the ring, the stresses resulting from dynamic unbalance and blade impingement, and their effect on engine mount. The successful operation of the newly commissioned test rig is tested under steady state conditions and we were able to demonstrate the applicability of the rig to blade shedding and containment tests in an efficient and cost effective manner.

这篇补充文章的第一部分涉及一种新型的仪器化按比例缩小的测试平台的设计，开发和调试，以检查航空燃气涡轮发动机叶片脱落（叶片掉落）事件期间释放叶片的动力学和密封性。按比例缩小的全刀片磁盘是使用通过白金汉公司的尺寸分析技术得出的非尺寸参数设计的。强制执行这些参数以确保按比例缩小的模型和实际的大型燃气轮机发动机具有动态等效性。带有驱动系统的转子封装在一个厚保护壳中，以将所有碎片包含在测试装置的范围内，并确保操作安全。该测试台配备了高速相机和许多传感器，这些传感器通过数据采集系统与两个处理器互连，以进行数据收集和数据管理。目的是测量释放的叶片轨迹，其与后叶片的多次相互作用，环内的密闭性，动态不平衡和叶片撞击产生的应力以及它们对发动机安装的影响。在稳态条件下测试了新调试的测试装置的成功运行，并且我们能够以有效且具有成本效益的方式证明该装置在叶片脱落和密闭性测试中的适用性。动态不平衡和叶片撞击产生的应力及其对发动机支架的影响。新调试的试验台的成功运行在稳态条件下进行了测试，我们能够证明该试验台以有效且具有成本效益的方式在叶片脱落和密闭性测试中的适用性。动态不平衡和叶片撞击产生的应力及其对发动机支架的影响。在稳态条件下测试了新调试的测试装置的成功运行，并且我们能够以有效且具有成本效益的方式证明该装置在叶片脱落和密闭性测试中的适用性。
