摘要
In aviation, a hard lading is an especially rapid or steep descent. The aircraft contacts the ground during landings, its vertical speed is instantly reduced to zero unless provisions are made to slow this vertical speed and cushion the impact of touch down, the fo rce of contact with ground may be so great and load imposed at the instant of touchdown may easily be three or four times the actual weight of the aircraft depending on the severity of contact then it leads to cause the structural damage to the aircraft. After that aircraft has to be inspected in different stages for damages before its next flight. In that one of the inspection stage is to check the radial distortion of the tapered roller bearing outer ring of the wheel hub for Main Landing Gears. In this context a tool concept was developed a nd designed for mandrel to check the radial distortion of wheel hub of LCA Main Landing Gears to eliminate rapid tyre wear and tyre pressure leakage problems.
