Contra-rotating rotors like on Sikorsky X2 solve the problem of lift dissymmetry by having both left and right sides provide near equal lift with less flapping.
12.
The rotors would still experience flapping as they rotate due to dissymmetry of lift between the two sides of the vehicle, but Carter Aviation claims this is manageable.
13.
Early rotor winged flight suffered failures primarily associated with the unbalanced rolling movement generated when attempting take-off, due to dissymmetry of lift between the advancing and retreating blades.
14.
"' Flap back "'or " blowback " is a phenomenon affecting the rotor of a helicopter as it overcomes dissymmetry of lift through flapping.
15.
Before this could be satisfactorily achieved, De la Cierva experienced several failures primarily associated with the unbalanced rolling movement generated when attempting take-off, due to dissymmetry of lift between the advancing and retreating blades.
16.
In addition, it was shown that CPL dissymmetry factors can be predicted computationally over a diverse sampling of known luminophore architectures, validating a new and facile tool for directing synthetic efforts in the search for anisotropic emitters.
17.
It also made the body of the condemned man the place where the vengeance of the sovereign was applied, the anchoring point for a manifestation of power, an opportunity of affirming the dissymmetry of forces . ""
18.
This is because the low airspeed of the retreating rotor blade would cause retreating blade stall, whilst the advancing rotor blade would be traveling at twice the speed of the aircraft, producing uncontrollable flight due to dissymmetry of lift.
19.
The failures of De la Cierva's previous designs, the C . 3, had led him to understand that he needed to overcome the problem of dissymmetry of lift in order to get an autogyro to fly without rolling over.
20.
Capable of measuring dissymmetry factors of even weakly luminescent materials to within a reported error as small as 10 " 6, the home-built CPL spectrometer created and used by the Bernhard lab is more sensitive than any previously demonstrated CPL spectrometer.
