In addition to systems for inspecting rotationally symmetric cylindrical parts, flux leakage inspection has been applied to very irregular components, such as helicopter rotor blade D-spars, gear teeth, and artillery projectiles. Several of these special-purpose applications have involved only laboratory investigations, but in some cases specialized instrumentation systems have been developed and fabricated for factory use. These systems are uniquely adapted to the particular application involved, and in most cases only one or at most several instrumentation systems have been built. Even in the case of laboratory investigations, special-purpose detection probe and magnetizing arrangements have been developed for specific applications. Charlie Chong/ Fion Zhang
