The leading edge of a sub-orbital, sounding rocket dictates an aerodynamically optimal profile which is difficult to manufacture. The university level offers no current standard to produce rocket nose cones made with pre-impregnated composites. Of particular interest is the molding technique used to fabricate a nose cone. The focus of...
This thesis presents work done to verify the accuracy of a
heuristic method for computing availability percentiles for
cascaded independent systems. Previous work has provided a model
for a single line that will be used as the basis for a simulation
of cascaded and parallel systems of lines. The simulation...
Female sexual promiscuity is a prevalent element of mating systems. One consequence of female sexual
promiscuity is that male‐male competition often continues post‐copulation within the female’s
reproductive tract. According to theory, the number of sperm a male inseminates relative to his rivals
strongly predicts his fertilization success. However, sperm quality...
The Oregon State University (OSU) Experimental Sounding Rocket Association (ESRA) 30k Rocket Team is a student run rocket team that competes in the Intercollegiate Rocket Engineering Competition at Spaceport America. The goal of the competition is to launch a student designed, manufactured, and tested experimental sounding rocket to 30,000 ft...
Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling at a scale functional for management. We used stratified random sampling and generalized linear mixed models to test hypotheses...
The purpose of this thesis was to understand the relation between the actual performance and the design performance of the manufacturing plane which was designed for the 2016 Design/Build/Fly competition. The actual performance was determined using an Arduino Uno based system with data from an accelerometer, gyroscope and pitot tube....
Human body flight is a relatively young sport with a largely undocumented history.
Human body flight is an umbrella term for any sport involving maneuvering one’s body in a
meaningful way through a column of relative wind. Human body flight includes skydiving,
which was the origin of human body flight,...
Some successful products are still developed and produced without the benefit of modern design techniques. One such product is a vibratory conveyor that has been developed largely through prototype iteration. The manufacturer has collaborated with Oregon State University to introduce model-based design into the development process. This research details a...
Unmanned Aerial System (UAS) technology is a rapidly developing technological marketspace. This thesis focuses on micro, tethered, coaxial UASs and the development of an electrically-tethered observation platform (ETOP). The thesis details the current status of the technology as well as current products on the market. Stability considerations, critical when adding...
