This paper investigates aerodynamic performance improvements of formation flight at transonic speeds for a medium size Unmanned Aerial Vehicle (UAV). The metric for assessing the aerodynamic improvement of formation flight is the computed drag. The total drag for each formation configuration is compared with a single UAV, where a final drag reduction percentage is estimated. The evaluation of the...
This paper proposes a guidance algorithm of a UAV for multiple targets tracking, considering physical constraints of the platform and its sensor. The on-board sensor used for target tracking is a camera. To relax the need of a gimbal system and provide flexibility in utilisation of the vision sensor, a new rotorcraft type of UAV is developed. The main focus in designing tracking guidance is to develop...
We propose a task allocation approach that combines the task's priority with a two-stage coalition formation algorithm in the context of multiple UAVs attacking multiple tasks. During the stage of forming a coalition for a task, the resource constraint of the coalition and resource depletion of a UAV are taken into consideration. When multiple UAVs are assigned to attack a complex task, it is reasonable...
