Desain Dan Analisis Struktur Wahana Terbang Quadrotor Fixed Wing Hybrid Uav (Qfhuav) Dengan Kemampuan Vertical Take-Off And Landing (Vtol)
Quadrotor Fixed Wing Hybrid UAV (QFHUAV) is a type of UAV that has vertical take-off and landing capabilities by combining the concepts of fixed wing and quadrotor types. From existing research, there is still a shortage of QFHUAV vehicles, namely minimal flight time. This study aims to develop a QFHUAV vehicle that has aerodynamic characteristics and has better power efficiency and an airframe construction that meets the safety factor. The process in designing the vehicle model uses the Solidworks 2019 software. Then the QFHUAV vehicle is calculated using the ANSYS Fluent software during the cruise phase to produce a lift coefficient of 0.6024 and a drag force of 0.0540. And the simulation of structural strength using ANSYS Static Structural software produces a deflection value of 10.47 mm in the design of the wing structure with a maximum stress of 17.512 MPa on the wing spar. The lowest safety factor value in the wing design obtained is 4.0057. Simulation of structural strength in the wing design produces a maximum deflection of 15.352 mm and the fuselage design produces a maximum deflection of 3.2618 mm. The maximum stress value obtained on the wing structure is 29.256 Mpa and the fuselage produces a maximum stress value of 39.189 Mpa. The lowest safety factor value produced is 1.569 on the wing and 1.7835 on the fuselage. The power needed to carry out the mission is 1125,018 watts for the take-off phase, 669,2710 watts for the cruise phase, and 712,5950 watts for the landing phase. With a cruise phase battery life of 33.5 minutes.
