The invention relates to a blade for a rotorcraft and the rotorcraft, the blade of the rotorcraft sequentially comprises a blade inner side section, a blade outer side section and a blade tip section along the spanwise direction, and the blade is distributed in a trend of increasing and then decreasing from the blade inner side section to the blade tip section relative to the chord length; and the relative chord length of the maximum blade is within the range. According to the technical scheme, the rotorcraft can have a small attitude angle in a high-speed forward flying state, and the ability of the rotorcraft to work on airborne equipment and transport goods is improved.

    本公开涉及一种用于旋翼飞行器的桨叶及旋翼飞行器,其中旋翼飞行器的桨叶沿展向依次包括桨叶内侧段、桨叶外侧段和桨尖段,桨叶相对弦长自所述桨叶内侧段向所述桨尖段呈先增大后减小的趋势分布,且最大桨叶相对弦长位于的范围内。通过上述技术方案,旋翼飞行器能够在大速度前飞状态下具有较小的姿态角,提高了旋翼飞行器对机载设备工作以及货物运输的能力。
