The Fiber Optic Pressure Sensor Array and its innovative technology that comes out of Phase I and II are not only applicable to aircraft testing at NASA, but also to many other fields where passive sensors of small size, high accuracy, robustness and networking features are important. Some of these applications are: Flight Testing Aircraft manufacturers use large numbers of sensors (as many as 4,000) to test and qualify aircraft; the networking feature drastically reduces cabling and testing costs. Wind Tunnel Testing - NASA and other international facilities. Airplane and Satellite Monitoring A large number of sensors of different types are used for on-board monitoring. Ship Monitoring There are thousands of sensors on board military and commercial ships
NASA main potential applications are in flight and ground/wind tunnel testing of aircrafts where surface pressure measurements are needed. The proposed Fiber Optic Pressure Array system, for many applications, is a better alternative to the Electronic Scanner Pressure (ESP) system, which are used across NASA wind tunnel facilities and flight test programs such as: 1. Subsonic Facilities Low-Speed Wind Tunnel at GRC Subsonic Tunnel at LaRC Vertical Spin Tunnel at LaRC 2. Transonic Facilities National Transonic Facility at LaRC Unitary Plan Facility at ARC Transonic Dynamics Tunnel at LaRC 3. Supersonic Facilities Supersonic Wind Tunnel at GRC Supersonic Wind Tunnel at ARC Unitary Plan Wind Tunnel (UPWT) at LaRC's Supersonic Wind Tunnel at GRC 4. Flight Loads Laboratory (FLL) at NASA's Dryden Flight Research Center (DFRC). This laboratory is already using fiber optic strain gage systems for structural testing.
