某型飞机机翼油箱输油仿真研究

研究飞机机翼油箱优化控制问题,燃油系统在飞机上是一个非常庞大而且复杂的系统,传统增压泵输油方案存在重量大、功率需求高的缺点.针对传统方法对燃油系统仿真研究建模复杂、耗时长的缺点,提出了利用油箱间增压压力差向消耗油箱输油的输油方案.利用流体仿真软件FLOWMASTER对燃油系统进行建模.对所建燃油系统模型进行仿真,结果表明,燃油系统各项性能指标能够满足系统需求,验证了所提方案的正确性,为改进和优化燃油系统设计提供了新思路和方法.

Wing Tank Supply System Simulation Study Based by Flowmaster

Fuel system is an enormous and complicated system in an aircraft,and the existence of traditional oil program was heavy and demanded high power.In this paper,a new program was put forward,which used pressure difference between tanks to deliver oil to consumption tank.In order to overcome the disadvantages of traditional method,such as complex fuel system simulation modeling and time-consuming,this paper used fluid simulation software FLOWMASTER to model the fuel system.Through the fuel system model simulation,the performance of fuel systems can satisfy the system requirements and validate the correctness of this program.This research provides a new idea and method to improve and optimize the fuel system design.
