Development of a smart wireless networkable sensor for aircraft engine health management

Oceana Sensor Technologies (OST) is working with the Joint Strike Fighter (JSF), DARPA, and the Office of Naval Research (ONR) under a cooperative agreement to develop a new class of networkable, smart sensors for prognostics and health management (PHM) aboard JSF, other aircraft, and industrial applications. We call these devices Intelligent Component Health Monitors or ICHM^TM. The ICHM has been prototyped in relatively large form factors built for normal industrial environments. The effort described herein has several objectives targeted to deliver a class of devices ready to be incorporated into the JSF design. Specifically we will: 1) environmentally harden the ICHM^TM design; 2) incorporate additional self-calibration/test functions; 3) integrate and demonstrate transducer technologies of Stewart Hughes Limited (SHL) with the Intelligent Component Health Monitor (ICHMTM); 4) integrate an ICHM-based engine sensor network; and 5) conduct testing in realistic engine and aircraft environments. This paper describe this development effort
