随着现代战争形势的变化,飞机性能不断提高,飞行员所处的环境也越来越严酷,航空供氧装备所应达到的技术要求也越来越高。为了满足飞行员供氧的需求,供氧调节器必须满足大流量、低吸气阻力、快速响应等性能指标。本文在分析肺式氧调器吸气活门结构和物理运动特性的前提下,建立了吸气活门的静态和动态数学模型,并运用数值模拟的方法对吸气活门进行了静态模拟,根据计算结果,对吸气流量、吸气阻力和活门开度的关系进行了分析。本文研究的内容对于氧调器吸气活门的优化具有重要的意义。
With the changes in the modern warfare situation, aircraft performance continues to improve, the pilots in which the environment is also more and more harsh, aviation oxygen equipment should meet the technical requirements are also getting higher and higher. In order to meet the pilot’s oxygen demand, oxygen regulator must meet the large flow, low suction resistance, rapid response and other performance indicators. In this paper, under the premise of analyzing the structure and physical movement characteristics of inspiratory valve, the static and dynamic mathematical models of inspiratory valve were established and the inspiratory valve was simulated by numerical simulation. According to the calculation results , The relationship between inspiratory flow, inspiratory resistance and valve opening was analyzed. The content of this paper is of great significance for the optimization of the inspiratory valve of the oxygenator.
