HALE (High Altitude Long Endurance) is one of the UAV classifications that has a mission as, among others: surveillance, monitoring, mapping, to pseudo-satellite. To fulfill one of its missions, which is long term flight (Long Endurance), HALE UAV requires quite a lot of energy to be able to maintain the flight. This large amount of energy is fulfilled by installing solar panels as a complement of battery power for days of flight. There are several factors that affect the flow of the air that passes through the HALE UAV due to solar panels, which are the heat generation from absorption of solar radiation and roughness from the surface of the solar panel itself. These factors can have an effect because of the solar panels that mounted on the top surface of the wing, which the wing is the main component for producing lift of the HALE UAV. This heat transfer will affect the flow near the surface which causes changes in air density resulting in changes in air flow. Surface roughness will make the flow of air near the surface unstable causing turbulent tendencies to increase and affect wing performance. Both of these phenomena can be identified by dimensionless numbers: Reynolds Number (Re), Nusselt Number (Nu), and geometry references (Ks/C). Another configuration of the HALE UAV design is that it has a high altitude flight operation, but has a low airspeed. This makes the air flow easily interrupted when passing through the wing. The approach that use for analyzing the changes of these aerodynamic performance is CFD method. This method was chosen because it can produce output values with small errors and does not require a large of cost. This research is expected to be a guideline for the selection of aerodynamic design of HALE UAV or other vehicles that have a design configuration by installing solar panels on its surface.
