Description
technical field [0001] The application belongs to the technical field of helicopter connection structures, and in particular relates to a rotary blade clamping device. Background technique [0002] When the helicopter is stored on the ship deck or in the hangar, in order to reduce the space occupied by the helicopter, the helicopter rotor needs to have a folding function. When the ship is sailing at sea, affected by the waves, there will be a large shaking phenomenon, which will cause the shaking of the helicopter blades. [0003] After the blade shakes, it is easy to collide with the body structure, causing damage to the blade and the body structure. In order to avoid damage to the blade and the body structure due to collision, it is necessary to clamp and fix the folded blade. [0004] Therefore, it is desirable to have a technical solution to overcome or at least alleviate at least one of the above-mentioned drawbacks of the prior art. Contents of the invention [00...
