We describe the wind-tunnel testing of a scale model gyroplane in the 3-m Low-Speed Wind Tunnel at the Aeronautical Research and Test Institute, Prague. These tests were conducted by the University of Glasgow as part of a U.K. Civil Aviation Authority funded research program into gyroplane airworthiness and flight safety. The wind-tunnel test program had two distinct aims. The first was to provide basic aerodynamic data on the effects of configurational characteristics of a gyroplane with a view to assessing the degree to which specific design features such as cowlings and tailplanes are beneficial to gyroplane performance. Secondly, it was intended to provide aerodynamic data for input to mathematical models to validate parametric studies of static and dynamic stability carried out as part of the overall research program
