The invention relates to the technical field of propellers, and discloses a propeller and a turboprop engine. A mounting section is formed at one end of the paddle, and the paddle is rotatably inserted into the mounting hole through the mounting section of the paddle; the variable-pitch assembly is matched with the mounting section; the counterweight structure is arranged outside the propeller hub and is assembled and connected with the mounting section; the measuring assembly comprises a measuring piece and an elastic piece, the measuring piece is movably arranged outside the propeller hub through the elastic piece, the measuring assembly is arranged outside the propeller hub, the measuring piece is in direct contact fit with the balance weight structure outside, and the elastic piece can press the measuring piece on the outer wall of the balance weight structure; the counter weight structure can directly push the measuring piece to move through the gradually changing outer wall of the counter weight structure during rotation, and the rotation position of the blade at the moment can be directly and effectively reflected through the detection end of the measuring piece, so that the measuring assembly can directly obtain the current pitch angle of the blade, and the control precision of the propeller can be effectively improved.
本发明涉及螺旋桨技术领域,公开了螺旋桨及涡桨发动机,螺旋桨包括:桨毂;桨叶,一端形成安装段,桨叶通过自身的安装段可转动的插设于安装孔中;变距组件,与安装段配合;配重结构,设置于桨毂的外部且与安装段装配连接;测量组件,包括测量件和弹性件,测量件通过弹性件可移动的设置于桨毂的外部,本发明在桨毂的外部设置测量组件,测量件在外部直接与配重结构接触配合,弹性件可将测量件压紧在配重结构的外壁上,配重结构在转动时通过自身逐渐变化的外壁可直接推动测量件移动,通过测量件的检测端即可直接有效的反应出此时桨叶的转动位置,使测量组件可直接获取桨叶当前的桨距角,能够有效提升螺旋桨的控制精度。
