Nick, I think you just slipped on your own bar of soap.
Excerpts from previous threads, which you participated in;
In opposition to the western perspective ~ " .... the single-rotor helicopter's tail rotor power consumption accounts for 10-12% of total power." ~ Eduard Petrosyan, Deputy Chief Designer of the Kamov Company
Nick, are you putting a little western spin on your percentages? ........
Would you agree that the torque of the main rotor must be offset in both hover and forward flight? In forward flight the 'angular drag' of the vertical stabilizer 'takes over' for the tail rotor?
.... In addition, the latest aerodynamic text (year 2000), by Leishman (University of Maryland) concurs with Kamov's position.
Graviman,
This is my 'top down'. Others may differ.
Top level; The Configuration.
- Future commercial and military VTOL craft may involve concepts that are currently no more than dreams.
- Rotorcraft is subset of VTOL. Rotorcraft's near term future WILL be twin counterrotating main-rotors (w/o tail-rotor).
- The intermeshing, the interleaving, the side-by-side, or all of them may be part of the future. IMO, the intermeshing is probably the best prospect for small, high performance rotorcraft.
Next level; The Rotor.
- The rotor is the essence of rotorcraft. Therefore, my current project is to develop and build the blade.
- This blade, with minor modifications, should be applicable to all of the above twin main-rotor configurations.
- In addition, If the current blade design does not work, the production methodology and equipment is still appropriate for the three alternative blade designs.
