Are you involved in an aircraft modification project wherein a device of some sort is fitted to the aircraft nose? (FLIR or movie camera of some sort)
If this is a one-off kind of project, keep it simple - don't get wrapped up in a big CFD analysis. There are several books you can look at that will give you a good feel for the loads involved. That should be sufficient for certification of a simple modification.
