Market Overview of the Vertical Take-Off and Landing Vehicles
Vertical Take-Off and Landing (VTOL) vehicles is a special class of Unmanned Aerial Vehicles (UAVs). This paper summarizes the current stage of VTOL design and market, and discusses VTOL growth and technical performance comparison. A database is presented to provide information concerning VTOL technical characteristics (maximum speed, payload, range, endurance, propulsion configurations), and V...
متن کاملCoordinated trajectory tracking of multiple vertical take-off and landing UAVs
This paper investigates the coordinated trajectory tracking problem of multiple vertical takeooff and landing (VTOL) unmanned aerial vehicles (UAVs). The case of unidirectional information flow is considered and the objective is to drive all the follower VTOL UAVs to accurately track the trajectory of the leader. Firstly, a novel distributed estimator is developed for each VTOL UAV to obtain th...
متن کاملAn automatic stabilization system for quadrotors with applications to vertical take-off and landing
In the last decade many studies have been conducted in the technological framework of Unmanned Aerial Vehicles (UAVs). There is great interest in developing autonomous UAVs, in particular, unmanned vertical take-off and landing (UVTOL) aircraft, because of their ability to conduct search and rescue missions in remote dangerous areas, without endangering human operators. The highly complicated f...
متن کاملLanding, perching and taking off from vertical surfaces
An approach is presented whereby small, unmanned aircraft can land on walls. The approach is demonstrated with a plane that uses an ultrasonic sensor to initiate a pitch-up maneuver as it flies toward a wall. The plane contacts the wall with spines that engage asperities on the surface. A non-linear suspension absorbs the kinetic energy while keeping the spines attached. A planar dynamic model ...
متن کاملAutomatic Take Off, Tracking and Landing of a Miniature UAV on a Moving Carrier Vehicle
We present a system consisting of a miniature unmanned aerial vehicle (UAV) and a small carrier vehicle, in which the UAV is capable of autonomously starting from the moving ground vehicle, tracking it at a constant distance and landing on a platform on the carrier in motion. Our visual tracking approach differs from other methods by using low-cost, lightweight commodity consumer hardware. As m...
