Static Stability Analysis on Twin Tail Boom UAV Using Numerical Method

The development of Unmanned Aerial Vehicle (UAV) technology in both developing and developing countries is ac celerating. In particular, UAV technology innovation for maritime affairs. The Aviation Technology Center has developed several UAVs used for the Maritime Surveillance System (MSS), which are marine surveillance and operations systems based on the use of UAV technology. Until now, several UAV variants have been developed, one of which is being developed is the LSU 05-NG. The main target of the design of the LSU 05-NG is to get a UAV as a lightweight utility platform and can operate in the marine environment and near the sea. Therefore it is necessary to do a static and dynamic analysis to determine the performance of the LSU 05-NG flight. In this paper using the numerical method VLM, CFD and DATCOM to analyze the aerodynamic characteristics of LSU 05-NG. Based on the results of the analysis of the values of CL, CD, CM, Cn,and Cl, it can be concluded that LSU 05-NG has static stability. Because the values CMα < 0,Clβ < 0 and Cnβ > 0.
