Abstract: Aiming at the issue that the branch pipe layout for aero-engine is poor at present, an automatic branch pipe layout method for aero-engine based on Steiner minimum tree and improved multi-objective firefly algorithm is proposed. In the method, based on Steiner minimum tree theory, a multi-objective optimization mathematical model for aero-engine branch pipe layout is firstly built, which takes the shortest pipe length, the least number of elbows and the least number of branch points as optimization objectives. Then, combining with the hybrid update strategy and elite strategy, an improved multi-objective firefly algorithm for aero-engine branch pipe layout is proposed based on Steiner minimum tree property, constraint violation theory and crowding degree theory, which realizes the automatic layout of aero-engine branch pipe. Finally, the feasibility and effectiveness of the proposed method are verified by standard test function and case study.
