Aircraft preliminary design stage Inertia load distribution optimization

Inertia load calculation is an important part of design of aircraft flight loads, the key is how to meet the requirements of weight and center of gravity is equipment to achieve rapid distribution to optimize the quality, paper established a mathematical model of inertia load distribution, through the permutations and combinations algorithm, determine three-dimensional scatter tetrahedron and Point location algorithm in tetrahedron,achieving and screening of effective combination of tetrahedral nodes, apply a Gaussian algorithm for solving the equivalent equations, that using quality cumulative method of node to achieve the optimal mass distribution successfully. Finally, an example proves the feasibility and effectiveness of the method.
