To provide a negative torsion variable blade which improves flight performance and a rotor craft.SOLUTION: The present invention discloses a negative torsion variable blade and a control assembly thereof. A blade 100 includes rigid first blades 5 and flexible second blades 6. When a driver pushes a root railing edge of the blade, the first blade is not flexibly deformed, and the second blade is torsionally deformed with a laminated elastomer structure between blade gratings to realize relative rotation deformation at both ends of the second blade, so that a flexible skin maintains airfoil contours, and the whole torsional degree of the blade is changed. The present invention also provides a rotor craft including the negative torsion variable blade.SELECTED DRAWING: Figure 1

    【課題】飛行性能を向上させる可変負ねじれブレード、および回転翼航空機を提供する。【解決手段】本発明は、可変負ねじれブレード及びその操縦アセンブリを開示する。ブレード100は、剛性の第1のブレード5及び柔軟な第2のブレード6を含む。駆動装置がブレードの翼根後縁を駆動すると、第1のブレードには柔軟な変形はなく、第2のブレードにはブレード格子間の積層弾性体構造を利用してねじれ変形し、第2のブレードの両端で相対回転変形を生じることで柔軟な外皮は翼型の外形を維持し、ブレード全体のねじれの程度を変化させる。本発明はまた、上記可変負ねじれブレードを含む回転翼航空機を提供する。【選択図】図1
