Exploration of the Potential of Civil Unmanned Aerial Vehicles Powered by Micro Gas Turbine Propulsion System

Civil Unmanned Aerial Vehicles (UAVs) are outnumbered compared to the military equivalents. They could however be of great value to various organizations, companies and the general public. They currently seem to be on the verge of a breakthrough. An interesting technology that could help increase the flight performance of civil UAVs is the micro...

An exploration into the potential of microturbine based propulsion systems for civil Unmanned Aerial Vehicles

A Master Thesis Research has been undertaken with the goal of investigating the potential of micro gas turbines as propulsion system of choice for small Unmanned Aerial Vehicle (UAV) used in civil applications. The UAV market is likely to develop great economic and technological importance on a near future because of the wide variety of...

Haptic Interface for UAV Teleoperation: Changing Haptic Control Device Stiffness based on Environmental Constraints

Unmanned Aerial Vehicle (UAV) teleoperators suffer from a reduced situational awareness, contributing to a high UAV accident rate. The implementation of a haptic interface is a way to provide them with more information about obstacles in the environment in order to compensate for this. Research focused on systems that actively help the...

Preliminary multi-mission UAS design

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...

Fixed-Wing UAV Integrated Navigation with Low-Cost IMU/GPS

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...

Accuracy Assesment of direct sensor orientation in UAV Photogrammetry

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...

Automating quantity surveying in road construction using UAV Videogrammetry

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...
