dissymmetry of lift मीनिंग इन हिंदी

उदाहरण वाक्य

1. 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.
2. 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.
3. "' Flap back "'or " blowback " is a phenomenon affecting the rotor of a helicopter as it overcomes dissymmetry of lift through flapping.
4. 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.
5. 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.
6. 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.
7. The advantage of the coaxial rotor is that, in forward flight, the lift provided by the advancing halves of each rotor compensates for the retreating half of the other, eliminating one of the key effects of dissymmetry of lift : retreating blade stall.
8. Because the advancing blade has higher airspeed than the retreating blade and generates a dissymmetry of lift, rotor blades are designed to " flap "  lift and twist in such a way that the advancing blade flaps up and develops a smaller angle of attack.
9. In this case, dissymmetry of lift and blade flapping could cause the rotor disc to tilt aft . With full forward cyclic control already applied, the rotor disc might not be able to be lowered, resulting in possible loss of control, or the rotor blades striking the tail boom.
10. A helicopter with a conventional rotor layout has a theoretical top speed of, after which it suffers from dissymmetry of lift . Some designs have successfully created hovering and high-speed aircraft, including the Bell Boeing V-22 Osprey tiltrotor that can fly at and the Sikorsky X2 compound helicopter that flew at, but both made significant aerodynamic compromises to hovering efficiency or range.
