Structural Design and Finite Element Analysis of a Vortex Jet Power Vehicle

Based on the existing unmanned aerial vehicles, this paper designs an unmanned aerial vehicle driven by turbojet power. According to the shortcomings of short endurance and low load capacity of motor-driven aircraft at present. With fuel as power source and micro-turbojet engine as driving force, the structure of aircraft is optimized through rational layout of micro-turbojet engine to achieve high power density ratio power output of aircraft. According to the designed aircraft structure, the finite element software ANSYS Workbench is used to carry out structural static analysis and modal analysis of the aircraft. The displacement nephogram, stress nephogram and safety factor nephogram of the flight structure are obtained under the condition of full load of the aircraft, which can guide the optimal design of the aircraft.
