中文摘要:
      随着燃料消耗,飞机副油箱内燃油的晃动特性将改变,并影响飞机飞行品质和安全。为准确高效地分析副油箱内燃油晃动行为,通过势流理论和有限元法建立了不同充液高度下燃油晃动的单摆等效力学模型。基于充液高度对单摆等效力学模型的各参数进行插值处理,提出了考虑燃料消耗的燃油晃动等效力学模型建立方法。以俯仰激励和滚转激励为例,对固定充液比和变充液比情形下的单摆等效力学模型进行了验证。结果表明,本文建立的等效力学模型对燃油动力学响应的预测结果与计算流体动力学软件的仿真结果吻合良好。可见,该等效建模方法在飞机副油箱内燃油晃动动力学描述上准确有效。
英文摘要:
      With the fuel consumption, the sloshing characteristics of the fuel in the auxiliary tanks will change, thus affecting the flight quality and safety of the aircraft. In order to analyze the fuel sloshing in the auxiliary tanks accurately and efficiently, the pendulum equivalent mechanical model of fuel sloshing for different filling heights was established by potential flow theory and the finite element method. The parameters of the pendulum equivalent mechanical model were interpolated based on the filling height, and the method of establishing the equivalent mechanical model of fuel sloshing considering fuel consumption was proposed. Taking pitch and roll excitations as examples, the pendulum equivalent mechanical models under the conditions of fixed and variable liquid fill ratio were verified. The results show that the predicted results of the fuel dynamic responses by equivalent mechanical model are in good agreement with the simulation results of computational fluid dynamics software. It can be concluded that the equivalent modeling method is accurate and effective in the description of fuel sloshing dynamics in the aircraft auxiliary tanks.
