摘　　要：目的为电子吊舱热管理系统设计提供实测数据支撑。方法在电子吊舱内部不同位置部署高精度温度传感器,并配套具有统一时标的参数采集设备,采集不同季节、不同飞行工况下电子吊舱内部的温度数据,获取舱内温度环境参数。结果当飞行工况稳定时,电子吊舱内部环境温度的稳定时间约为1200 s,稳定值与当地大气总温的差别小于3℃。在不同飞行工况下稳定飞行时,舱内温度高于当地大气静温。以高空(11 km)飞行工况为例,当地大气静温为-50~-60℃,由于舱体蒙皮受气动加热影响,舱内环境温度仍维持在-40℃以上。结论飞行工况不同,吊舱内部环境温度有显著差别,随飞行工况变化,吊舱内部环境温度的变化相对滞后,其响应速度与材料导热能力正相关。To support the design of electronic pod thermal management system,a survey analysis of ambient temperature inside a electronic pod has been conducted.The electronic pod is carried by aircraft platform,and multiple high-precision temperature sensors are deployed inside the electronic pod,and they are equipped with parameter acquisition equipment with unified time scale.The cabin temperature is collected under different flight conditions in different seasons,and the results are as follows:Response of ambient temperature inside electronic pod lags far behind of the change of flight conditions,and positive correlation has been found between the response speeds and thermal conductivity of materials.When flight condition remains stable,the ambient temperature inside electronic pod,which is higher than the local atmospheric static temperature,becomes stable in 1200 seconds.Taking high altitude flight conditions(11km)as an example,the local atmospheric static temperature range is(-50~-60)centigrade,but the ambient temperature inside electronic pod remains above -40 centigrade,because the pod’s skin is affected by aerodynamic heating.The conclusion of this paper is that there are significant differences of the ambient temperatures inside the pod under different flight conditions.When flight condition remains stable,the ambient temperature inside electronic pod,which is close to the total temperature of local atmosphere,becomes stable in 1200 seconds.
