Webb(1) Telemetry provides direct in-flight measurement of engine RPM and airspeed. (2) Radar gun and (video) sound measurements were used to quantify model speed and engine RPM under specific flight conditions. These in-flight speed and RPM data were then used to evaluate the propeller performance. Webbspeed of sound is 340.3 m/sec but at an altitude of 15 kilometers where the temperature is down to 216.7 K the speed of sound is only 295.1 m/sec. This difference indicates that an airplane flying at this altitude encounters the speed of sound at a slower speed, and, therefore, comes up against compressibility effects sooner.
