| Abstract: |
| ObjectiveTo get the correct boundary conditions for thermal design of aerial camera.MethodsThermal environments of aerial camera pod were analyzed systematically.ResultsAccording to the analysis, calculation methods for radiative heat transfer should consider atmospheric transparency and ground conditions, convective heat transfer especially on the leeward side can be calculated by experience expression developed by Hilbert, aero-dynamic heat transfer can be estimated using the reference enthalpy method developed by Eckert, and ice accretion of outside surfaces and fogging on the view-port window were concluded. In addition, thermal control methods of anti-icing and anti-condensing were also discussed.ConclusionThe analysis results can be used as boundary conditions of aerial camera thermal design and such a research can be used for thermal analysis of other aerial camera pods. |
