Description
Summary:Development of an instrument that can provide dynamic flow parameters in supersonic propulsion research resulted in a drag probe. It functions by measuring the drag on a flat cantilever beam exposed transversely to a flowfield. Drag is also measured indirectly with strain gauges attached on opposite sides of the beam's base. Results show that the drag force anemometer can be most useful in supersonic and subsonic flow regimes. Normal shock relations between subsonic and supersonic drag probe results have also been established. They indicate that a subsonically calibrated drag probe is supersonically calibrated as well.
