Remote Pilot Situational Awareness With Augmented Reality Glasses: An Observational Field Study, Jeffery Coleman, David Thirtyacre

International Journal of Aviation, Aeronautics, and Aerospace

With the use of small unmanned aerial systems (sUAS) proliferating throughout industry and public safety, it is imperative to ensure safety of flight. The Federal Aviation Administration (FAA) published regulations for commercial use of sUAS in 2016 and included the requirement to maintain visual line-of-sight with the aircraft at all times. However, due to the nature of the sUAS ground control stations (GCS), remote pilots time-share between observing the aircraft and interacting with the display on the GCS. Time-sharing between the aircraft and GCS can be seen as similar to the cross-check a pilot uses when flying a manned aircraft ...

Unauthorized operation of a UAV may present privacy or security risks. A software-defined radio (SDR) or other receiver can be used to monitor a specified range of frequencies to provide detection of wireless communication signals suspected of relating to UAV operation. A protocol detector corresponding to a trained classifier can be applied to data packets demodulated by the SDR. A transmitter can then be triggered to provide warnings by injecting warning data into a video channel in response to the detected protocol. Control of the UAV can be established by transmitting simulated control commands that overwhelm the signals received from ...


Cooperative Aerial Search And Localization Using Lissajous Patterns, Josiah Steckenrider, Spencer Leamy, Tomonari Furukawa 2020 United States Military Academy

Cooperative Aerial Search And Localization Using Lissajous Patterns, Josiah Steckenrider, Spencer Leamy, Tomonari Furukawa

West Point Research Papers

This paper presents a cooperative aerial search-and-localization framework for applications where knowledge about the target of concern is minimal. The proposed framework leverages the sweeping oscillatory properties of Lissajous curves to improve an agent's chances of encountering a target. To accurately estimate the states of cooperative search drones, a discrete-time linear Lissajous motion model approximation is presented in such a way that uncertainty in physical model parameters can be accounted for. These uncertainties are propagated through estimation formulas to improve both agent and target localization relative to a static base station. Numerous experiments conducted in a physics-driven simulation environment ...

The maintenance cost of a commercial aircraft comprises airframe, components, and engines. The most expensive of them are engines, which may represent up to 60% of an aircraft cost, and therefore will have a significant impact on any airline finance. As a result, engine fleet maintenance management is crucial for any airline sustainability. Apart from heavy maintenance where life-limited parts are replaced and its performance restored, aircraft engines are often required to come off wing for light repair due to operational issues like foreign object damage, high oil consumption, and vibration issues. In other cases, even though being operational, engines ...
