摘要/Abstract

摘要： 为满足军用飞机座舱光照模拟需求、提高热流模拟的准确性，提出一种大功率辐照式热流模拟系统。该系统可以模拟不同高度下太阳光照环境，并可结合环境模拟舱的低温冷却及气压调节系统，在地面进行军用飞机在飞行过程中的结冰、除冰模拟仿真实验；还可以对驾驶员进行不同光照环境下的视觉负荷实验和视觉功效实验，模拟飞行过程中光照对飞行员的影响。通过设计仿真发现：热流模拟辐照系统辐照范围可达到1 500 mm×3 500 mm；在工作距离1 000 mm内，最大辐射能量可达到1.89 sc（1 sc=1 353 W/m²），辐照均匀性可达到±12.2%. 对实际试验系统进行测量，最大辐照能量可达到1.80 sc，辐照均匀性可达到±13.3%，与仿真结果接近，验证了系统的准确性和可靠性。为满足军用飞机座舱常用需求，对单灯进行了低气压环境试验，试验结果表明：该系统单灯结构可满足低气压环境工作，后续可进一步开展热流模拟辐照系统整体的特殊环境试验，为军用飞机环境控制系统及环境模拟技术奠定基础。

Abstract: The demand for environmental simulation of fighter or military aircraft operation is gradually increasing with the increasing demand for fighters and military aircrafts in China. A high power irradiated heat flow simulation system is proposed to meet the requirements of military aircraft cabin lighting simulation and improve the accuracy of heat flow simulation. The system can simulate the sunlight environment at different altitudes. It can simulate the process of icing and deicing flight together with the use of low temperature cooling and air pressure regulating system in environment simulation cabin. At the same time， the visual load test and visual efficacy test in different lighting environment can be carried out to simulate the impact of lighting on the pilot during flight. Through design and simulation，it is found that the radiation area of heat flux simulation irradiation system is 1 500 mm×3 500 mm， the maximum radiation energy can reach 1.89 sc(1 sc=1 353 W/m²) within the working distance of 1 000 mm， and the radiation uniformity can reach±12.2%. An experimental system was measured. The measured maximum irradiation energy can reach 1.80 sc， and the irradiation uniformity can reach±13.3%，which is close to the simulated results，verifying the accuracy and reliability of the radiation system. In addition，in order to meet the common needs of military aircraft cockpit，the low-pressure environment test of a single lamp was carried out. The test results show that the single lamp structure of system can meet the work in the low-pressure environment. The following special environment test of the whole heat flow simulation irradiation system can be further carried out.
