Always wondered.......despite an established and well researched "single main rotor + tail rotor" config ...what was N I Kamov's inspration behind the seemingly complex and untreaded "Coaxial " territory.
Starting this thread to discuss concrete results on
1.==> Performance advantages
2.==> Handling qualities (Stability and manoeuverability)
3.==>Other factors
Performance
A 10 to 16% advantage in terms of useful load has been cited by the Coaxial helicopters in various books/research papers/ claims.
Q. Whats the explanation for this ?
Handling Qualities
How do the longitudinat / lateral / directional stability compare with a conventional configuration helicopter?
Coments on the manoeuverability and comparison.
Please pitch in and lets all get enlightened.
For starters I found a sort of compendium of all research on Coaxial helicopters....

Quiet a few point of views and gets confusing on the results.
