Short Strand Carbon Fiber Reinforced Polylactic Acid Filament For Additive Manufacturing, Dale Chenoweth, Lukas Seggi, Luke Phillips Jan 2024

Short Strand Carbon Fiber Reinforced Polylactic Acid Filament For Additive Manufacturing, Dale Chenoweth, Lukas Seggi, Luke Phillips

Williams Honors College, Honors Research Projects

In this design project, the additive manufacturing filament of short strand carbon fiber (SSCF) reinforced polylactic acid (PLA) composite was developed. The micro-size, precision cut SSCFs were mixed with the PLA pellets through a melting homogenization process. Through this process the composite material block is cut and divided into pieces for ease of pelletizing. The material block pieces are then pelletized to be fed through the single screw extruder to develop the SSCF-PLA composite filament. The SSCF-PLA filaments were manufactured with a varying amount of SSCF ranging from 0.5% to 10% of the material block's weight. Development of a 1% …

Systems Engineering In Zips Aero Design, Benjamin Kemal Sabic, Mathieu Kumiega

Williams Honors College, Honors Research Projects

This research project has the goal of implementing systems engineering in the Zips Aero Design team at the University of Akron at a general member level. The use of systems engineering techniques will be employed to keep every member on track throughout the competition season. The deliverables of this project are the PDR, CDR, AIAA DBF Proposal, AIAA Technical Design Report, the Prototype Aircraft, and the Competition Aircraft.


Integrated Organizational Machine Learning For Aviation Flight Data, Michael J. Pritchard, Austin T. Walden, Paul J. Thomas Jan 2024

Integrated Organizational Machine Learning For Aviation Flight Data, Michael J. Pritchard, Austin T. Walden, Paul J. Thomas

Journal of Aviation/Aerospace Education & Research

Increased availability of data and computing power has allowed organizations to apply machine learning techniques to various fleet monitoring activities. Additionally, our ability to acquire aircraft data has increased due to the miniaturization of small form factor computing machines. Aircraft data collection processes contain many data features in the form of multivariate time series (continuous, discrete, categorical, etc.) which can be used to train machine learning models. Yet, three major challenges still face many flight organizations: 1) integration and automation of data collection frameworks, 2) data cleanup and preparation, and 3) developing an embedded machine learning framework. Data cleanup and …


External Runtime Execution Monitoring Of A Cyber Physical System Via Trace Interfaces, Peter Vaughan Truslow Jan 2024

External Runtime Execution Monitoring Of A Cyber Physical System Via Trace Interfaces, Peter Vaughan Truslow

Theses and Dissertations

In the past two decades, Unmanned Aerial Systems have progressed from expensive military hardware or one-off custom builds, to include off-the-shelf drones that can be purchased for a rather affordable price and flown by nearly anyone. As the technology and performance have improved, the door is opened to applications that require operation in environments where the consequences for failure are high, such as operating in the navigable airspace or in urban environments, or with human passengers. This requires a great deal of trust in the reliability and integrity of the control systems of the aircraft. A method of monitoring the …


Implementation Of Cavity Vortex Generators To Mitigate Stall And Ice Accretion On The Naca 0012, Eric Pernell Jan 2024

Implementation Of Cavity Vortex Generators To Mitigate Stall And Ice Accretion On The Naca 0012, Eric Pernell

College of Graduate Studies: Theses & Dissertations

With the growing environmental concerns of international aviation carbon emissions are driven by the ever-increasing commercial aviation traffic. This study aims to increase the aerodynamic efficiency of the NACA 0012, by implementing cavity vortex generators with the intent to increase the effective stall angle without a substantial increase of drag. This study is performed with Reynolds Averaged Navier-Stokes (RANS) at a low Reynolds of 5.0E+04 with varying cavity depths along the leading edge. The depths study is placed at 10 percent cord at depths of 3, 5, and 10 percent cord. All cavity vortex generators effectively increased the stall angle …
