Graviman,
The project is moving ahead, but it is no small undertaking, particularly for one person. It calls upon so many disciplines, and the only interesting one is rotor aerodynamics. Below are a couple of pictures. One shows some of the components for the CNC workstation and the other shows the development of the workstation's controller.
It is coming together, slowly. If the prototype and concept eventually shows promise then outside parties might be interested in accelerating the development.
Delta3,
Very little development work has been done on Reverse Velocity. Perhaps, if over the past sixty years the majority of helicopters had been built with two main rotors, there would have been twice as much incentive to pursue this field of research.
The only work, which I know of, that might be close to your project is a thesis done in 2003 and entitled 'Investigation of Increased Forward Flight Velocities of Helicopters Using Higher Harmonic Stall Control and Reverse Velocity Rotor Concept'. He has modified the basic JANRAD computer program to included the above. This booklet has a 78-page appendix that lists his coding to modify the basic program.
