摘要: 研究了机场保障装备与其工作环境背景的红外对比度特性,重点对装备车头部分进行红外伪装设计,经过结构、材料优化设计和热物性实验测试,最终研制出由2层3 mm厚陶瓷纤维夹一层3 mm厚相变石蜡胶囊中间层组成的新型隔热毯。为检验该新型隔热毯的防热红外伪装效果,使用了热红外成像仪进行实测,并结合ANSYS进行数值模拟。研究结果表明,使用该隔热毯后,机场保障装备与背景的温差可得到有效控制,满足机场保障装备红外伪装要求。研究了机场保障装备与其工作环境背景的红外对比度特性,重点对装备车头部分进行红外伪装设计,经过结构、材料优化设计和热物性实验测试,最终研制出由2层3 mm厚陶瓷纤维夹一层3 mm厚相变石蜡胶囊中间层组成的新型隔热毯。为检验该新型隔热毯的防热红外伪装效果,使用了热红外成像仪进行实测,并结合ANSYS进行数值模拟。研究结果表明,使用该隔热毯后,机场保障装备与背景的温差可得到有效控制,满足机场保障装备红外伪装要求。

Abstract: The infrared contrast between airport support equipment and its working background is studied, and an infrared camouflage scheme for the front part of a car is made. After a series of experiment on structure and materials, a new kind of heat insulation blanket is developed, which comprises two 3 mm thick ceramic fiber layers and a 3 mm thick phase-change paraffin wax capsule layer sandwiched in them. To verify its camouflage effect, field experiment is conducted with a thermal imager, and numerical simulation is made by using ANSYS. It turns out that this heat insulation blanket can be used effectively to control the temperature of equipment and background, which meets the infrared radiation camouflage specifications.
