Design and Simulation of LALE Vertical Take-off & Landing Aircraft

This paper presents the designing of low altitude long endurance (LALE) VTOL UAV aircraft for particularly given mission requirements. To fulfil the mission requirements of VTOL UAV, an analytical methodology is established. The analytical design and performance calculation is achieved by MATLAB(version 2020). On behalf of the designed value, the VTOL UAV aircraft is replicated into X-Plane software. The designed X-Plane VTOL UAV aircraft is used for the detailed simulation and validation of the calculated performance. In X-plane, detailed modeling of individual components is done, and flight tests are performed in different environments for endurance benchmark. A VTOL has five primary flight regimes, namely, take-off, forward transition, cruise, reverse transition, and landing; for all these flight regimes, the state of the charge of the battery is studied. Paper also has the interface of simulation strategy to control the fixed-wing VTOL UAV aircraft in manual simulation.
