一种飞机试验保温系统及其参数优化方法
技术领域
本发明涉及飞机测试技术领域,具体为一种飞机试验保温系统及其参数优化方法。
背景技术
飞机气候实验室作为装备环境试验的大型承载设施,其需要容纳全尺寸飞机、特种车辆等装备,能提供全天候、不受时间限制的高温、低温、淋雨、降雪等实验环境条件,这就要求飞机气候实验室具有最基本的保温功能,飞机气候实验室保温功能主要依靠实验四周维护结构壁板、地坪以及天棚板的隔热实现,实验室四周围护结构一般采用标准尺寸的保温壁板拼接组成;为了保证飞机实验室的保温密封功能尽可能的良好,实验室围护结构应避免开口;但实验室无论是平时的检查维护工作,还是试验时人员、设备进出实验室,或检查被试装备性能、功能等工作,均要求实验室四周维护结构上设置必要数量的开口以便人员通行、设备穿越等,因此保温壁板开口包边的处理做法优劣直接关系到保温壁板的保温功能是否良好。
