航空燃油离心泵参数化设计方法研究综述

Fuel centrifugal pump is a core component of aeroengine control system. Combined with the current technical development and design needs of aeroengine fuel centrifugal pump，this paper presents a review of the parametric design methods and optimization design strategies for the centrifugal pump. Four parametric design methods and optimization design strategies are first examined，together with comparative investigations on their advantages and deficiencies. To cope with the randomness and blindness during the traditional design processes，this paper then introduces three optimization methods for centrifugal pump design，which includes the global optimization methods based on heuristic algorithm，the optimization design methods based on gradient，as well as the optimization design method based on agent model. This is followed by clear addressment of the scientific and technical problems to be fixed for the three optimization design methods. By studying the state-of-the-art developments of fuel centrifugal pump in aeroengine developed countries，the technical challenges，the problems and the technical development direction of aeroengine fuel centrifugal pump are pointed out for our country. Finally，based on the domestic design capabilities of our country，some fundamental research problems to be addressed for enhancing the design ability of fuel centrifugal pump for our country are summarized.
