Station Probe (Pratt & Whitney)
Pratt and Whitney uses "station probes" to measure pressures and temperatures in the flow path of gas turbine engine subsystems, including the fan, low and high-pressure compressors , combustor, high-pressure turbine, and low-pressure turbine. The principle goal for the modularized probe program is to build a working prototype of a station probe that is wirelessly connected to the data acquisition system. This requires rethinking the probe design to embed the entire signal conditioning hardware into the probe. In addition, the electronic networking and link into the data system will have to be changed. This year's team will focus on the design of the probe-environment control systems and the integration of last year's team's work into a prototype system. The environment control system will ensure the accuracy and precision of the pressure and temperature sensors. A wireless station probe will greatly reduce cost as less effort will be required to interface with the station probes. Tests of the prototype will be done in a Pratt and Whitney high-speed wind tunnel.
