PREDICTED FLIGHT PERFORMANCE OF THE WRIGHT 'FLYER' BASED ON FULL-SCALE TUNNEL DATA

An analysis of the flight performance of the Wright 1903 ‘Flyer’ is presented, based on recently available data for aerodynamic and propeller characteristics, together with a mix of historical and contemporary data for the engine, weather conditions, weights, and dimensions. It is shown that the flight performance was marginal, that the 'Flyer' may have been limited to operation in ground effect, and that take-off from a 60 foot launch rail was impractical without a stiff headwind. Further, it is shown that commonly accepted values for engine power and in-flight propeller RPM may be underestimates. The analysis highlights the systems integration prowess of the Wrights, whereby successful flight was achieved with very little margin for error.
