Open Architecture Fiber Optic Engine Monitoring System

Luna Innovations Incorporated proposes to develop a flight hardened, universal, fiber optic sensor system for the measurement of multiple physical parameters of interest. The purpose of this system is to provide an open architecture that will universally accept fiber optic sensors including those based on Extrinsic Fabry-Perot Interferometers (EFPIs) and Fiber Bragg Gratings (FBGs). Fiber optic sensors are completely EMI-immune and are an enabling technology for emerging fly-by-light flight systems. The system will be optimized for weight, volume, and power consumption appropriate to a flight environment. Special emphasis will be placed on developing the system to work with a broad range of fiber optic sensor types such that various sensors can be monitored using a single system. Part of the project will focus on developing a smart network which will minimize interconnect volume, while providing seamless network interconnectivity. During Phase I, a prototype system will be designed and a wide range of sensor variables tested with an existing development system. Sensor testing will focus on developing robust algorithms and calibration data protocols which will enhance versatility. During Phase II, Luna will work with engine and airframe OEM partners to design a system and network that is ready for flight qualification.
