A Rational Approach to Comparing the Performance of Coaxial and Conventional Rotors [PDF]

Journal of the American Helicopter Society, 2010
The merit, in terms of its efficiency and performance, of the twin, contrarotating coaxial rotor configuration over the more conventional single rotor system has long been a point of contention. Previously published comparisons yield seemingly inconsistent and conflicting conclusions. In this paper, the basis for a fair, like-for-like comparison of the
