A Technique to Determine Lift and Drag Polars in Flight,

Abstract

Performance trials of the European combat aircraft TORNADO have concentrated on the systematic measurement of lift and drag polars. Such polars have been successfully measured by means of well-adapted test instrumentation, a data reduction system, and a high calibration standard of the aircraft and engines. The use of a certain combination of steady-state and dynamic test maneuvers has resulted in a drastic reduction in the amount of flight time required to obtain sufficient data for the determination of the zero lift drag, induced drag characteristics and drag increments due to aircraft configuration changes. Flight test results are presented which demonstrate the advantage of the test technique used and the high data quality achieved.
