<P>PROBLEM TO BE SOLVED: To provide main rotor maintenance equipment that enables an assembly with the inclination of an internal constituent component (yoke) corrected and is able to preclude trouble that a main rotor blade cannot be folded because in disassembly and assembly maintenance working of the main rotor that has a folding mechanism for the main rotor blade of a helicopter, during the maintenance assembly time, the main rotor blade is removed, accordingly, weight is not exerted to cause that inclination. <P>SOLUTION: During an assembly time, a dummy blade 8 is mounted on a yoke 5 of a main rotor to enable a load having the same weight as a main rotor blade to be exerted on the dummy blade 8 by means of load generation equipment. In addition, on this maintenance equipment, folding/unfolding operation confirmation of the main rotor blade can be performed. According to this, simulating the state in which the main rotor blade is mounted enables the exact correction of inclination of the internal constituent component (yoke 5) which occurs during the assembly time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
