Barrett, R. (author), McMurtry, R. (author), Vos, R. (author), Tiso, P. (author), De Breuker, R. (author)This paper describes a new class of flight control actuators using Post-Buckled Precompressed (PBP) piezoelectric elements. These actuators are designed to produce significantly higher deflection and force levels than conventional piezoelectric actuator elements. Classical laminate plate theory (CLPT) models are shown to work very well in...conference paper 2005

Vos, R. (author), Barrett, R. (author), Krakers, L. (author), Van Tooren, M. (author)This paper presents the use of a new class of flight control actuators employing Post-Buckled Precompressed (PBP) piezoelectric elements in morphing wing Uninhabited Aerial Vehicles (UAVs). The new actuator relieson axial compression to amplify deflections and control forces simultaneously. Two designs employing morphingwing panels based on PBP...conference paper 2006

Tadema, J. (author), Koeners, J. (author), Theunissen, E. (author)In the past fifteen years, several research programs have demonstrated potential advantages of synthetic vision technology for manned aviation. More recently, some research programs have focused on integrating synthetic vision technology into control stations for remotely controlled aircraft. The contribution of synthetic vision can be divided...conference paper 2006

Barrett, R. (author), Vos, R. (author), De Breuker, R. (author)This paper describes a new class of flight control actuators using Post-Buckled Precompressed (PBP) piezoelectric elements to provide much improved actuator performance. These PBP actuator elements are modeled using basic large deflection Euler-beam estimations accounting for laminated plate effects. The deflection estimations are then coupled...conference paper 2007

Tadema, J. (author), Theunissen, E. (author), Koeners, J. (author)The guidance information that is available to the UAV operator typically suffers from limitations of data update rate and system latency. Even when using a flight director command display, the manual control task is considerably more difficult compared to piloting a manned aircraft. Results from earlier research into perspective guidance...conference paper 2007

Tadema, J. (author), Theunissen, E. (author)For Unmanned Aerial Vehicles (UAVs), autonomous forms of autoland are being pursued that do not depend on special, deployability restraining, ground-based equipment for the generation of the reference path to the runway. Typically, these forms of autoland use runway location data from an onboard database to generate the reference path to the...conference paper 2008

Lam, T.M. (author)In the teleoperation of an uninhabited aerial vehicle (UAV), the human operator is physically separated from the vehicle and lacks various multiple-sensory information such as sound, motions, and vibrations of the airframe. The operator is usually only provided with visual information, e.g., from camera images with limited resolution and field...doctoral thesis 2009

Wortel, T.P. (author)Due to changing contract forms in road construction, contractors feel the need for accurate and fast quantity measurement methods. UAV Photogrammetry is a potential answer for contractors. Photogrammetric measurement processing should be automated in order to reach its full potential in speed and obtainability. Automatic extraction of reliable...master thesis 2009

Van Zomeren, M. (author)The current way of communicating situation awareness through sketches has been found not sufficient as is seen during exercises of usar.nl. The proposed solution RubbleViewer presents the personnel with a 3d map where they can annotate information on. This map of a collapsed building is calculated by running photogrammetric algorithms on an...master thesis 2009

Stam, J. (author)With the advent of Unmanned Aerial Vehicles, it becomes possible to use these vehicles to acquire photogrammetric images in a more cheap and flexible way compared with conventional photogrammetry from a full-sized airplane. A big factor in costs and resources in conventional photogrammetry is signalling and measuring ground control points, which...master thesis 2011

Hummelink, B.A. (author)Today, there is an increase in the use of Unmanned Aerial Vehicles (UAV's), for applications that can be considered dull, dirty or dangerous when compared to those applications of conventional aircraft or helicopters. To further increase the use of UAV's, their navigation filters must be robust and reliable. The trend in current autopilot...master thesis 2011

Duives, D.C. (author)Several pedestrian crowd events that became disasters occurred in the last decade. Most of these events were either religious festivals, sport or music events. Even though these events are organized frequently, not a lot is known about pedestrian crowd movements. One of the key problems in the analysis is the lack of crowd movement data....master thesis 2012

Van der Spek, I.T. (author), Voorsluys, M.H. (author)In this thesis first a study is conducted on which position determination method should be used in a UAV and especially in the Parrot AR.Drone. Then an autonomous control for the AR.Drone is designed. The best position determination method in this case appeared to be a combination of a GPS sensor and a barometer. The autonomous control is...bachelor thesis 2012

Veerman, H.C.M. (author)Unmanned vehicles are important when it comes to performing a desired task in a dangerous or inaccessible environment. Unmanned robots, have been successfully used for many years. More recently, a growing interest in Unmanned Aircraft Systems (UASs) has arisen. In the past few years the development of sensors, microprocessors and propulsion...master thesis 2012

Homulle, H.A.R. (author), Zimmerling, J.T. (author)An embedded electronic camera system for unmanned aerial vehicles (UAV) was developed in the scope of the final bachelor project at the TU Delft in 2012. The aim of the project was to develop a prototype for a new UAV competition. The electronic system of the prototype had to able to track an object, make a picture of it and send it to a ground...bachelor thesis 2012
