Abstract/Summary
This document outlines the final design phase for the Solar Turbines Variable Damper project, aiming to enhance the safety and serviceability of gas turbines enclosure ventilation system. The primary focus of this project is to address the challenge of maintaining optimal internal pressure within the gas generator enclosures while enabling remote control of the damper position.
In this report, the full system design is described in detail. Then, the part procurement, manufacturing, and assembly of the variable damper and test stand is provided to outline the steps and processes taken to complete the final prototype. After discussing the final prototype, the design specifications, completed tests, and final results are detailed to highlight the design validation process. Lastly, there is a discussion and recommendations section where the team outlines the final results and discusses the next steps for the project.
The team has gone through extensive iteration and prototyping to justify our design. We have specified an actuator that meets our torque requirements and provides protection from the environment. The team has also developed a schedule logic that we believe will best control the enclosure pressure while minimizing the cycles on the shaft. Through our fatigue and strength analyses, we are confident that the design meets the engineering specifications regarding strength and reliability. Through our testing, we validated that the actuator we selected is appropriate for the system, we proved that the schedule logic could be implemented to control enclosure pressure, and we set out a schedule bucket tuning process.
As a formal agreement, this document signifies the final design for the variable damper project, presenting critical test results and ensuring alignment among project stakeholders prior to completing this project.
