| Abstract: |
| 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. |
