This paper presents the computational aerodynamics analysis of a complete EAV(Electric Aerial Vehicle) configuration propeller rotating effect is applied. EAV-2H, being developed by KARI(Korea Aerospace Research Institute) is a technology demonstrator for HALE(High Altitude Long Endurance), solar energy and secondary battery is used to power this aircraft. Also it has been applied for long-endurance, high aspect ratio, low Reynolds airfoil. Computational analysis predicts the performance of the propeller and cruise power and it was verified by wind tunnel and flight tests.

Aerodynamic design of the vane type multi-function probe was tried by using CFD and wind tunnel test for the MALE UAV and small business jets. The present multi-function probe con measure total pressure, static pressure and angle of attack by using rotating vane. Therefore, major performances are determined by aerodynamic characteristics of vane. In oder to design the sensor compatible to the requirement, aerodynamic characteristics of sensors was investigated by using CFD and dynamic response analysis was also performed for transient performance. The final aerodynamic performance was measured by the wind tunnel test at Aerosonic and the results are compared with the present design. The results showed that the aerodynamic design using the CFD can be successfully used for the design of vane type multi-function air data sensor.
