The Cyclogyro or Paddle Wheel Aircraft continues to intrigue inventors. The rotating wing on this concept does not form a disc but a cylinder. In forward flight, each blade traces out a cycloid in the side view. Compared to the conventional rotor, it has the advantage that each blade element is operating at the same velocity
11 Feb 2014 The picture above describes the cyclogyro principle better than I could: I hope it is readable. The lowest part of the diagram shows (possibly rather optimistically) how a cyclogyro suffering engine failure could still glide to a forced landing. Personally, I think it would have glided like a grand-piano.

cyclogyro/PECyT propulsion system: Helicopter, Fixed Wing, Dirigible and an unconventional aircraft design. More details about the design, performance and viability of such concepts were given in D2.8, D2.9. Mathematical modelling. Several mathematical models were developed by the consortium partners (see D2.5 for
The cyclogyro, or cyclocopter, is an aircraft design that uses cyclorotors as the principal source of lift, propulsion, and control. In principle, cyclogyros are capable of vertical take off and landing and hovering performance like a helicopter, while potentially benefiting from higher forward speed, lower noise and vibration levels,
Abstract. The investigation on analysis of a cyclogyro using Unsteady Vortex Lattice Method (UVLM) is presented in this paper. There exists many simplified method for cyclogyro design analysis, but they are quite crude and do not fully deal with problems with complex configurations and motion patterns. By solving N-S
Request (PDF) | Cyclogyro thrust vec | This work discusses the possibility to use the cycloidal rotor technology to provide anti-torque to otherwise conventional helicopter designs. A simple analytical model of cycloidal rotor aeromechanics is provided to support its sizing. The analytical model is validated using other

Request (PDF) | Review of Historic a | This paper summarizes the state of knowledge of cyclogyro theory and development in order to aid those working on researching and designing cyclogyros. A cyclogyro is a horizontal- axis rotary-wing aircraft. While no cyclogyros have ever been successfully flown, the concept offers
Abstract. The investigation over several possible coclogyo designs was performed in the paper. The concept of cyclogyro has existed almost 100 years, but still more research are needed. The effects of taper ratio, aspect ratio and winglets are investigated in this paper. The comparison between different designs shows that
