Air Supremacy, The Enabler Of Close Air Support Operations – An Evaluation Of Past, Present, And Future Air Campaigns., Owen Topolnicki Dec 2024

Air Supremacy, The Enabler Of Close Air Support Operations – An Evaluation Of Past, Present, And Future Air Campaigns., Owen Topolnicki

Senior Honors Theses

The achievement of gaining aerial supremacy, or lack thereof, is the hinge upon which Close Air Support (CAS) swings. The attainment of it enables CAS specialist aircraft, not unlike the Ju-87 Stuka or A-10 Thunderbolt II, to be exceptionally effective in their operating environment. While the lack of it, forces aircrews to pioneer new solutions either in the form of multi-role aircraft (capable of self-defense), or other innovative solutions similar to unmanned aerial systems (UAS’s), as aptly seen in the ongoing Russo-Ukrainian conflict. Thus, the ability of an air force to gain air supremacy and to do so quickly, …

A System Architecture For Phased Development Of Remote Suas Operation, Eric Ashley Mar 2020

A System Architecture For Phased Development Of Remote Suas Operation, Eric Ashley

Master's Theses

Current airspace regulations require the remote pilot-in-command of an unmanned aircraft systems (UAS) to maintain visual line of sight with the vehicle for situational awareness. The future of UAS will not have these constraints as technology improves and regulations are changed. An operational model for the future of UAS is proposed where a remote operator will monitor remote vehicles with the capability to intervene if needed. One challenge facing this future operational concept is the ability for a flight data system to effectively communicate flight status to the remote operator. A system architecture has been developed to facilitate the implementation …

Uas For Public Safety Operations: A Comparison Of Uas Point Clouds To Terrestrial Lidar Point Cloud Data Using A Faro Scanner, Joseph S. Cerreta, Scott S. Burgess, Jeremy Coleman Jan 2020

Uas For Public Safety Operations: A Comparison Of Uas Point Clouds To Terrestrial Lidar Point Cloud Data Using A Faro Scanner, Joseph S. Cerreta, Scott S. Burgess, Jeremy Coleman

International Journal of Aviation, Aeronautics, and Aerospace

Unmanned Aircraft Systems (UAS) can be useful tools for public safety agencies during crime or vehicle accident scene investigations if it can provide value to the resource-constrained agency. The speed of data collection, while minimizing first responder risk, while sustaining an acceptable level of accuracy and precision compared to other tools is where the agency may find value. During a recent homicide investigation in Florida, a UAS provided saved 81% in law enforcement labor hours with an acceptable level of accuracy compared to traditional methods. The purpose of this research was to compare UAS to determine if there were differences …

Urban Flow And Small Unmanned Aerial System Operations In The Built Environment, Kevin A. Adkins Jan 2019

Urban Flow And Small Unmanned Aerial System Operations In The Built Environment, Kevin A. Adkins

International Journal of Aviation, Aeronautics, and Aerospace

The Federal Aviation Administration (FAA) has put forth a set of regulations (Part 107) that govern small unmanned aerial system (sUAS) operations. These regulations restrict unmanned aircraft (UA) from flying over people and their operation to within visual line of sight (VLOS). However, as new applications for unmanned aerial systems (UAS) are discovered, their capabilities improve, and regulations evolve, there is an increasing desire to undertake urban operations, such as urban air mobility, package delivery, infrastructure inspection, and surveillance. This built environment poses new weather hazards that include enhanced wind shear and turbulence. The smaller physical dimensions, lower mass and …

Assessment Of Asymmetric Flight On Solar Uas, Eric Belfield Dec 2016

Assessment Of Asymmetric Flight On Solar Uas, Eric Belfield

Master's Theses

An investigation was conducted into the feasibility of using an unconventional flight technique, asymmetric flight, to improve overall efficiency of solar aircraft. In this study, asymmetric flight is defined as steady level flight in a non-wings-level state in- tended to improve solar incidence angle. By manipulating aircraft orientation through roll angle, solar energy collection is improved but aerodynamic efficiency is worsened due to the introduction of additional trim drag. A point performance model was devel- oped to investigate the trade-off between improvement in solar energy collection and additional drag associated with asymmetric flight. A mission model with a focus on …

A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender Oct 2016

A Bioinspired Modification For Uas Propeller/Rotor Noise Reduction, Mark N. Callender

ASA Multidisciplinary Research Symposium

This projects presents a bioinspired modification to UAS propellers/rotors for noise reduction. Sound pressure levels (SPL) and thrust for modified propellers were compared to a baseline propeller. The bioinspired modification yielded lower SPL with a requisite increase in rpm in order to maintain a chosen level of thrust.

Thinking Rather Than Panicking About The Current Drone Threat, Tom Foley, Tyrone Groh Jan 2015

Thinking Rather Than Panicking About The Current Drone Threat, Tom Foley, Tyrone Groh

Aviation / Aeronautics / Aerospace International Research Conference

Originally titled "UAS Threats in Sport Venues," the authors opted to expand their focus to better to all threats from UASs, and to encourage better preparation for and responses to such threats. Foley and Groh discuss different strategies.
