Intelligent Shims for Aviation Systems

在航空航天工业中，安全至关重要。垫片在推进系统和机体子系统的连接中起着关键的作用。仪表化（智能）传感器可以提供有关接头和部件完整性的信息，这将有助于提高飞机安全性，增加其可靠性并降低运营成本。该项目是Shimco为将智能垫片（IntelliShim）引入航空航天市场而进行的综合开发计划的一部分。这些设备将机械间隙管理、传感和能量收集集成到一个组件中。该项目的具体目标是开发嵌入式垫片传感器，以满足航空航天市场的健康监测需求。微机电系统（MEMS）是满足这一需求的理想技术平台。制造技术是成熟的、稳定的和廉价的。该项目的目标是开发低功耗压电和/或静电垫片嵌入式MEMS力，力矩和温度传感器，可以集成到MEMS中，而不会破坏关节的机械完整性。

Safety is paramount in aerospace industry. Shims play a critical role in joining components of the propulsion and airframe subsysterms. Instrumented (intelligent) shims can provide information about joint and component integrity, valuable insight that will help improve aircraft safety, increase their reliability, and reduce the operation costs. This project is part of an integrated development plan undertaken by Shimco to introduce Intelligent Shims (IntelliShim) to the aerospace market. These devices will integrate mechanical gap management, sensing, and energy harvesting into one component. The specific goal of this project is to develop shim-embedded sensors to serve the health monitoring needs of the aerospace market.Microelectromechanical systems (MEMS) are an ideal technology platform to meet this need. The fabrication technology is well developed, stable, and cheap. The goal of this project is to develop low-power piezoelectric and / or electrostatic shim-embedded MEMS force, moment, and temperature sensors that can be integrated into shims without undermining the joint mechanical integrity.
