Abstract

The development of technology on unmanned aerial vehicles is shown by increasingly required in military and civilian field, one of them is in traffic monitoring missions. The mission is in the middle of the city so it is difficult to get the runway to take off. Therefore the UAV V-Sky 14 provides solution with vertical take-off landing (VTOL) innovation. The tail is a flight control part of the aircraft, so the tail structure is important to note. So in this study discuss the analysis of structural strength to determine the maximum stress that occurs and the safety of the tail structure. Geometry data of UAV V-Sky 14 along with tail of UAV V-Sky 14 are modeled by CATIA then input into ANSYS Software for fluida simulation and structure simulation. Fluid flow and structure weight are the load in the UAV V-Sky 14 structure simulation. The loading of V-SKY 14 UAV structure is carried out during cruising conditions with a Load factor of 3.8 and two loading area, namely the horizontal tail and vertical tail. And there are variations in the deflection of the rudder and the elevator is taken at the values of 0o , 5o , 10o and 15o . The results of the analysis get the value of the stress then do the calculation of Margin of Safety. This research has the highest maximum stress in horizontal stringer at 201,16 MPa. It occurs while horizontal tail loading and an elevator deflection angle at 15o . The value of Margin of Safety is 3.31. The largest total deformation is also found in the same conditions with different parts. It is in the horizontal tail at 74,084 mm. The Margin of Safety from simulation results is declared safe, even though it needs reinforcement of structures in certain parts.
