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 …

2015-2016 Eraudb Aiaa Design/Build/Fly Technical Report, Trevor W. Perrott

Student Works

The economic potential of small unmanned aerial vehicles (SUAVs) has been well documented and reported. According to the Association for Unmanned Vehicle Systems International (AUVSI), there is an associated economic impact from the growth of the UAV industry. The goal of the American Institute of Aeronautics and Astronautics Design/Build/Fly Competition Research Program (AIAA DBF CRP) is to investigate design and manufacturing methods for application to SUAVs within the scope of the AIAA DBF Competition.

Students were engaged in the application of aerospace engineering knowledge for the production of a dual-aircraft system. Through the use of Computational Fluid Dynamics (CFD), Computer …

Development Of A "Multi-Cut" Payload For Use In Stratospheric Ballooning Missions, James Flaten, Joey Habeck, Noah Biniek, Steven Smeaton, Austin Langford, Jordan Diers, Isaac Krieger

2017 Academic High Altitude Conference

The ability to cut strings (AKA lines) during stratospheric ballooning missions has a wide variety of uses including, but not limited to, (a) flight termination (i.e. cutting payloads away from the main balloon), (b) cutting away excess lift balloon(s) to slow ascent rate (and possibly achieve float), (c) cutting away ballast weights to slow descent rate or increase ascent rate, (d) cutting away burst balloon(s) on descent to avoid parachute entanglement, and (e) cutting away payloads which are intended to return to the ground independently, for experimental purposes. We report on the development of a “multi-cut” payload box that uses …

Risk-Based Approach To Assessment Of Advanced Technologies For Conceptual Design, Adipratnia Asmady

Master's Theses

The conceptual design phase of an aerospace system development program is typically characterized by short duration and relatively limited resources, yet design decisions are made that have critical implications on program risk. To address the more aggressive requirements, one of these decisions is the selection of advanced technologies. System developers need to assess advanced technologies early on, but are faced with uncertainties surrounding the potential net benefits. The concept introduced in this study is uncertainty characterization as a way to better understand the associated risk. A framework was developed to guide the interaction between the technology developer and the system …

Tilt-Rotor Drone, Benjamin Stone, Zachary Crandall

Electrical Engineering

A drone is defined a "an unmanned aircraft that can fly autonomously[2]." In the year 2016, there exist many applications for small scale drones. Drones, having had primarily military applications, now have use in hobby robotics, photography, and even in surveying. But drones have not yet been perfected and still have room for much improvement. Several problems with drones come in the form of battery life, stability, and size. Large drones can fit many sensors and probes, but are heavy and have less flight time. For autonomous drones, stability can be an issue even though there exist many stable drones. …

Uav As A Service: Providing On-Demand Access And On-The-Fly Retasking Of Multi-Tenant Uavs Using Cloud Services, Justin Yapp

Doctoral Dissertations and Master's Theses

As commercial roles for Unmanned Aerial Vehicles (UAVs) become more well-defined and demand for the services provided by them increases, UAVs rely more on new cloud computing services and co-operative coordination to provide mission planning, control, tracking and data processing. We present UAV as a Service (UAVaaS) framework, which brings features commonly found in traditional cloud services, such as Infrastructure, Platform, and Software as a Service, to the domain of UAVs. Our work aims to conceptualize and design UAVaaS for commercial applications. Specifically, a cloud-provided orchestration framework that allows multi-tenant UAVs to easily serve multiple heterogenous clients at once and …

2d Aeroacoustic Analysis Of Flow In The Flame Trench, Meghan Pokorski

Doctoral Dissertations and Master's Theses

We present here a methodology for using the commercial software ANSYSFLUENT to predict the acoustic field associated with Space-Launch System (SLS). We consider a two-dimensional model of flame deflector, and flame trench. The ANSYS code is then used to simulate the internal flow. Both the steady state case is considered along with other cases where the inflow has a harmonic component. A Ffowcs-Williams Hawking (FWH) surface is then constructed within the computational domain to use the computed flow fluctuations to obtain the acoustic field. The acoustic data was then compared to the experimental data.

When using the ANSYS code for …

High Power Rocket Design Report, Laura E. Calcara, Monica Fernandez, Chris Green, Trent Hosokawa

Honors Thesis

Highpower rockets are extremely sensitive systems that require precise planning, testing, and analysis in order to yield accurate results. Under the guidance of project advisor, Dan Larson, a highpower rocket was designed and built to reach an apogee of 3000 feet. Additionally, means of dual deployment was used in order to aid in the safe descent and recovery of the rocket. In order to meet this expectation, two parachutes were used in conjunction with black powder ejection charges. Compliance with the safety standards of NAR and NFPA was met for the ejection system used in dual deployment. To ensure that …

Examining American Attitudes On The Use Of Military Drones, Todd Brandon

Political Science Theses and Capstones

Recent polls have revealed that Americans of both the political left and right support the use of military drones. This statement stands true among groups who traditionally do not support the use of military force. I hypothesize that people of a more liberal persuasion will be more concerned with whether or not the drone program endangers innocent civilians, while those of a more conservative view will be more concerned with the legality of conducting military drone strikes. I analyze data obtained from the Pew Research Center to examine people's attitudes on military drone strikes via framing theory. My hypothesis has …
