With the slowly diminishing supply of fossil fuels across the world and the heightened risk of carbon dioxide pollution leading to global warming, a shift towards renewable energy is gaining momentum. Recent advances in wind and solar power technology have increased the power density of alternative sources while decreasing the cost per kilowatt-hour, but the technology has not become advanced enough yet for large scale deployment. Combined Power Cooperative has developed a revolutionary design for a concentrated solar power plant that utilizes Fresnel reflectors and a large body of water in which to install them. In addition to being low-cost, …

Engine Simulation And Diagnostic Test Bed: Final Design Report, Jeff Lewis, Cody Scott, Todd Smith

Mechanical Engineering

The San Luis Obispo High School Automotive Technology Shop has a 1991 Buick V-6 Engine which uses the OBD-I (On-Board Diagnostics, generation one) standard for diagnostic testing and troubleshooting. In order to expand the capabilities of the Automotive Technology program and allow students to gain first-hand experience troubleshooting older OBD-I engines, the shop has a need for this engine to become part of a diagnostic and troubleshooting test bed. Some of the diagnostic tests the students will perform include checking cylinder pressure, monitoring coolant system temperatures, interpreting error codes from the OBD-I system, and conducting enhanced smog testing. All of …

Mechanical Engineering

Mission Statement

The purpose of this project is to design, build, and test a thrust-vectoring rocket nozzle which will aid in controlling the trajectory of a solid-booster rocket. The system prototype must meet the requirements set forth by the sponsoring enterprise.

The Enterprise

Stellar Exploration is a small space systems technology company located in San Luis Obispo, CA. Stellar Exploration is currently seeking a thrust-vectoring system for its Silver Sword rocket.

Project Scope

The design and analysis portion of this project accounted for a system that would be mounted on to a rocket for operational flight. Therefore, this team has …

Rayleigh Test Apparatus Design Report, Josef Duller, Owen Raybould, James Nicovich

Mechanical Engineering

The Rayleigh Test Apparatus is a device that will be used to test the thermodynamic properties of Nitrous Oxide to assess the feasibility of using this fluid as a coolant for a hybrid rocket aero spike. The aero spike is intended to redirect the propulsion flow as it leaves the engine to create a more efficient flow pattern at low and high altitudes. However, there are issues of overheating which leads to melting of the aero spike. For this reason, the use of nitrous oxide (N2O) as a coolant is being explored. N20 is being considered because it is already …
