This Small Business Innovation Research Phase I project will address the development of algorithms for active control of blade vibration and engine stability (stall and surge) using the General Dynamics Advanced Technology Systems (GDATS) eddy current sensor (ECS) array. The increased demand for aircraft maneuverability and efficiency drive the engine designers to produce lighter engines that will have to operate in the presence of increased levels of steady-state and dynamic engine-face distortion. Such engines demand active control systems for safe operation. Working closely with GDATS, the proposer has been actively involved in the development of signal analysis and diagnostic tools for the detection of engine faults. We shall leverage this ongoing development of diagnostics tools for the ECS in the development of active control algorithms. Current ECS diagnostic tools are already able to provide tip clearance profiles, as well as vibration and stall indicators. We propose to extend the functionality of the ECS system beyond diagnostics to active and automatic real-time control of gas turbine engines. From this project we expect to develop algorithms for active control of gas turbine engine blade vibration and stability that make use of the GDATS ECS array. The GDATS ECS array is currently the favored sensor system for installation on the Joint Strike Fighter. A software system upgrade capable of using ECS data to compute the necessary indicators and estimate the disturbances needed for active vibration and engine stability control will be highly desirable. If this can be accomplished it will reduce the number of new sensors needed for active control, thus potentially saving millions of dollars.

该小型企业创新研究第一阶段项目将使用通用动力先进技术系统（GDATS）涡流传感器（ECS）阵列开发叶片振动和发动机稳定性（失速和喘振）主动控制算法。对飞机机动性和效率要求的提高促使发动机设计者生产更轻的发动机，这些发动机必须在稳态和动态发动机面畸变水平增加的情况下工作。这样的发动机需要主动控制系统来安全操作。与GDATS密切合作，提案人一直积极参与开发用于检测发动机故障的信号分析和诊断工具。我们将在开发主动控制算法时利用ECS诊断工具的持续开发。 目前的ECS诊断工具已经能够提供叶尖间隙轮廓以及振动和失速指示器。我们建议将ECS系统的功能扩展到诊断之外，以主动和自动实时控制燃气涡轮机发动机。 从这个项目中，我们希望开发算法的主动控制的燃气涡轮机发动机叶片的振动和稳定性，利用GDATS ECS阵列。GDATS ECS阵列是目前最受欢迎的安装在联合攻击战斗机上的传感器系统。一个软件系统的升级，能够使用ECS数据计算必要的指标和估计所需的主动振动和发动机稳定性控制的干扰将是非常可取的。如果能够实现这一目标，将减少主动控制所需的新传感器数量，从而可能节省数百万美元。
