Grounded aerial futures : humanism + the city in the aerial age
New technologies directly related, and tangentially linked to airport services and functions will drastically change the airport infrastructure typology including city connectivity, space allocation, environmental circumstances and security. With this change, there will be a need for cities to …

Soft Aerial Manipulation
… fully exploits the advantages of softness in aerial manipulation. Manipulation and grasping with unmanned aerial vehicles (UAVs) currently require accurate positioning and are often executed at reduced speed to ensure successful grasps. This is because modern aerial manipulation platforms …

Modeling Aerial Refueling Operations
Aerial Refueling: AR) is the act of offloading fuel from one aircraft: the tanker) to another aircraft: the receiver) in mid flight. Meetings between tanker and receiver aircraft are referred to as AR events and are scheduled to: escort one or more receivers across a large body of water; refuel one …

Dynamic Stability and Handling Qualities of Small Unmanned-Aerial-Vehicles UNMANNED-AERIAL-VEHICLES
<p>General aircraft dynamic stability theory was used to predict the natural frequencies, damping ratios and time constants of the dynamic modes for three specific small UAVs with wingspans on the scale from 0.6 meters to 1.2 meters. Using USAF DatCom methods, a spreadsheet program for predicting …

RF Fingerprinting Unmanned Aerial Vehicles
<p>As unmanned aerial vehicles (UAVs) continue to become more readily available, their use in civil, military, and commercial applications is growing significantly. From aerial surveillance to search-and-rescue to package delivery the use cases of UAVs are accelerating. This accelerating popularity …

Aerial manipulation for indoor applications
… presents the design and control of a small aerial manipulator operating in indoor environments. The critical challenges of functioning effectively in such environments are (i) maximizing workspace in constrained spaces like narrow corridors or tight corners, and (ii) achieving stable flight …

Large-scale probabilistic aerial reconstruction
While much emphasis has been placed on large-scale 3D scene reconstruction from a single data source such as images or distance sensors, models that jointly utilize multiple data types remain largely unexplored. In this work, we will present a Bayesian formulation of scene reconstruction from …

Trusted Unmanned Aerial System Operations
Proving the correctness of autonomous systems is challenged by the use of non-deterministic artificial intelligence algorithms and ever-increasing lines of code. While correctness is conventionally determined through analysis and testing, it is impossible to train and test the system for all …

Control of cooperative unmanned aerial vehicles
… small cooperative unmanned autonomous quadrotor aerial vehicles. A new approach is proposed, for the modeling of the system’s dynamics using linearized Piecewise AffineModels. The Piecewise Affine dynamic–models cover a large part of the quadrotor’s flight envelope while also taking into account …
