title: Aerodynamic Design of Modern Gyroplane Main Rotors
author: Stalewski, Wienczyslaw
comment: The popular 8H12 airfoil is perhaps not the last word in autogyro rotor design. Here is an investigation of other profiles, using (of course) computational fluid dynamics. The chaps who do that stuff in my company come up with some really amazing results. This group from Poland has also conducted flight tests which showed a considerable improvement. Further tests are planned to take place soon. There is a very nice plot showing the driving and driven regions of a blade around the disk.
