Embodiment 1
[0036] This embodiment provides an unmanned helicopter rotor retractable device. When working, first open the tail boom clamping part 1, and install the rotor retractable device to the tail boom as a whole. The position is the front end of the tail boom, the tail boom The rear end face of the clamping piece is in contact with the front end face of the diagonal brace installation sleeve. Put the upper and lower parts of the tail beam clamp together, so that the tail servo cable and GPS cable at the lower part of the tail beam are placed in the reserved slot of the tail beam lower clamp. Manually tighten the rubber head nut 10, and press the lower end plane of the rubber head nut 10 against the inclined plane of the clamping part on the tail beam through the "T" shaped shaft 9;
[0037] The rotor clamping part 8 on the upper part of the rotor retractable device is fully opened, so that the upper part of the rotor clamping part 8 is freely suspended;
[0038] Rotate the two-blad...

Description
technical field [0001] The invention relates to a rotor retractable device, in particular to an unmanned helicopter rotor retractable device. Background technique [0002] As the lifting surface and control surface of the helicopter, the rotor is the most important key component in the helicopter system. Helicopter rotor blades are made of composite materials. When the blades are subjected to large instantaneous loads, internal delamination of composite materials and cracks between composite materials may occur. This kind of internal damage is generally difficult to find in the naked eye inspection. If the blade with such internal damage is applied to the flight of a helicopter, it will cause a major accident. [0003] Therefore, in order to ensure the safety of the rotor blades and reduce the transient load on the rotor blades during helicopter transportation, the traditional method is to separate the rotor blades from the hub and store the rotor blades separately in the b...
