Recent Results Obtained with a New Method for Measuring Aircraft Power and Drag in Flight
Progress is reported in the development of a method to extract thrust horsepower and drag simultaneously from accelerated flight maneuvers. Although the flight data still is not as self-compatible as desired, the extracted drag and power obtained from a pullup-pushover agree reasonably well with the results from steady flight determinations for drag and wind tunnel tests for power. In the level flight acceleration only the extracted CDO value agrees closely. Further work is necessary to define the proper power model and to make the level flight acceleration data more self-compatible.
