I am supporting the integration of new avionics in a fighter aircraft. My company developed cooling devices for the new avionics equipment and performed some steady state and transient FEA modeling. To further define operating parameters of the new avionics, more steady state analysis is required on the cooling capability of the cooling devices. The task involves heat soaking the aircraft in a hangar by using heat lamps to do so, as this will provide a better control, as compared to the environmental variables of performing this task outside in a real sun soaked environment. The intent is to heat the area around a compartment located in the aircraft's lower rudder section. I understand the aircraft will act as a big heat sink, posing error, but the real goal here is too determine/approximate compartment temperature and how quickly the cooling devices can vacate the heated air once the devices are turned on. The question - finally, is based on the intensity of the heat lamps (which I do not know yet) what distance from the aircraft's skin should the lamps be located to somehow represent a sun induced heat soak condition? I know the question has many variables, so if anyone has past experience in testing and or mimicking a heat soak condition as I mentioned will be valuable. I would want the lamps positioned so the temperature would stabilize, but not be too hot or too cold, but somewhat equivalent to a sun soaked condition. Hope I explained this enough.
