DatPWG - Design of the Data Acquisition for a New Large Scale Facility for Aerodynamics and Heat Transfer Measurements on a Turbine Platform

Kurzfassung

For an internship at DLR in Göttingen a LabView program has been written that will control a new facility at which aerodynamic and heat transfer measurements will be done on a turbine platform. Involved in this program were the measurement systems PSI 8400, Keithley, step motor and a RPT pressure reference box. The step motor and RPT programming has not been done because these two systems were not available yet at the time of programming. The step motor needs a critically damped control mechanism to measure the direction of ejection flow at the facility. Futher the program has to be thoroughly tested when the construction of the new facility is completed in 2002. Within this report the already existing Straight Cascade wind tunnel as well as the used measurement techniques are described and a short explanation of the LabView program is given.
