Abstract
The present disclosure provides a negative torsion variable paddle and a control assembly thereof. The paddle includes rigid first paddles and rigid second paddles. When a driver pushes a root railing edge, the first paddle is not flexibly deformed, and the second paddle is torsionally deformed with a laminated elastomer structure between cascades to realize relative rotation at both ends of the second paddle, so that a flexible skin maintains airfoil contours, and the whole torsional degree of the paddle is changed. The present disclosure also provides a rotor craft including the negative torsion variable paddle.
