Maintenance Path Planning for Aircraft Virtual Maintenance

We present a path planning algorithm for virtual maintenance of aircraft components. Component disassembly is a troublesome challenge of aircraft maintenance due to contact collision happened inevitably in disassembly process, which makes maintenance work difficult and inefficient. We study component disassembly in virtual environment: first a hierarchical and associative relation model is constructed through component analysis. Relation model contains connection information for components in any level. We adopt matrix representation for relation model that makes it convenient for computation. Finally, dijkstras algorithm is used to find the optimum disassembly path. The test on full-size model of Osprey airplane motor propeller shows our algorithm is effective and efficient.
