Calibration Systems and Turbine-Type Flow Transducers for Cryogenic Flow Measurements
In rocket engine development, it is not unusual to require accuracies or precisions beyond the capabilities of existing measurement techniques. This need for improved measurements has been the underlying motive for the development of various cryogenic flow calibration systems. This paper will discuss the Pratt’& Whitney Aircraft liquid-hydrogen and liquid-oxygen flow calibration systems and will review performance characteristics of the turbine-type flowmeters that have been tested.
