Abstract�� The algorithm of modeling civil airliner gasoline tanks and modifying the attitude error of tank volume sensors was provided. Tank surface was generated with triangle mesh based on two-dimensional Delaunay triangulation and interpolation. Using the wrong result of gasoline volume sensors, current attitude error and surface triangle mesh, logical prisms and tetrahedrons were generated. The correct volume was calculated with total volume of prisms and tetrahedrons. The algorithm was compared with the current slice algorithm in efficiency and applicability. Solving the three-dimensional modeling of civil airliner tank and the modification of attitude error of tank volume sensors with that finished model, this algorithm is more effective and efficient than slice algorithm.
Keywords�� civil aviation   fuel tank   attitude error   triangulation nets
