Currently multicopters are facing a continuous growth in terms of recreational uses, and multiple companies focused on these aircrafts to facilitate certain tasks that were nearly inaccessible humans, or otherwise involved great cost. In this context, the drone swarm concept allows us broaden incorporate new, more refined applications which various aircraft coordinate with each other carry out ...

Vertical take-off and landing (VTOL) is a type of unmanned aerial vehicle (UAV) that growing rapidly because its ability to take off land anywhere in tight spaces. One VTOL UAV, the tail-sitter, has best efficiency. However, besides efficiency offered, some challenges must still be overcome, including complexity combining hover like helicopter fly horizontally fixed-wing aircraft. This research...

Most types of Unmanned Aerial Vehicle (UAV, drone) missions requiring Vertical-Take-Off-and-Landing (VTOL) capability could benefit if a drone’s effective range be extended. Example include Search-And-Rescue (SAR) operations, remote inspection distant objects, or parcel delivery. There are numerous research works on multi-rotor drones (e.g., quadcopters), fixed-wing drones, VTOL quadplanes, til...

An approach to the control of a VTOL vehicle equipped with complementary thrusttilting capabilities that nominally yield full actuation of the vehicle’s position and attitude is developed. The particularity and difficulty of the control problem are epitomized by the existence of a maximum tilting angle which forbids complete and decoupled control of the vehicle’s position and attitude in all si...

Tailsitter UAVs with their combined vertical take off and landing (VTOL) and fixed-wing aircraft with full flightspeed regime capability provides a distinct alternative to rotary-wing and ducted fan UAVs (OAVs). ITU-BYU Tailsitter concept aims to obtain the energy efficient regimes across the VTOL and the cruising flight regimes. This paper describes the hybrid propulsion system design approach...

Due to their ability to hover and to fly “low and slow” VTOL UAVs are of extreme strategic importance. The task of control of VTOL UAVs is however complicated as they exhibit highly coupled nonlinear dynamics and inherent instability. These intricacies limit the performance of linear control techniques since a single linearized state space model represents only a limited part of the flight enve...
