A flight test method was developed for a quarter-scale model aircraft with minimum onboard instrumentation for the determination of the Drag Polar, the Thrust Required curve and the Power Required curve. The test included a wind tunnel test for propeller efficiencies and thrust coefficients, a torque test for engine shaft horsepower, and a flight test for flight speeds at measured operating conditions. The only additional onboard instrumentation besides that for radio control was a small cassette recorder. Two methods are described for data manipulation and an error analysis is provided for each method.http://archive.org/details/flighttestmethod00bamiCaptain, Hellenic Air ForceApproved for public release; distribution is unlimited
