  1. Tin Can Turbine SHS Technology Engineering Design Course – Fall 2012 ACTION PLANS Students will be given a solid introduction to Engineering Design Process before building the turbine. Students will be given lecture on the principles of turbine engines including handouts showing applications of gas turbines. Students will observe 3D animations of turbine engine functions and operation. Students will freehand draw their turbine design and then use CAD software to refine their design and create part dimensions. Students will use their CAD designs to locate, dimension, and obtain lab supplies to begin turbine construction. Students will measure all components and fit according to their CAD design. Students will create and assemble the turbine housing, turbine shaft, the turbofans. Students will create and install fuel injection system and starter system; Students will create a blast shield to protect them in the event of catastrophic turbine event. Students will do a web quest to find POH engine start, engine abort start, and engine shutdown from commercial turbine manufacturer (e.g. Rolls Royce, GE, Pratt and Whitney) to create their own turbine operators manual. Students will use the checklist to start the engine, operate it for 3 to 5 seconds and use the checklist to shut down safely after taking temperature measurements at the intake compressor, hot section, and tail pipe. Students will monitor interturbine temperatures (ITT) with a Vernier thermocouple while simultaneously recording audio and video of turbine operation with tablet computer. Using a rudimentary thrust measuring tool (Vernier anemometer) and vary fuels (LPG, LNG, Propane, Butane, etc) to determine which fuel produces maximized thrust at minimized ITT. (time permitting) STUDENT OUTCOMES Students will learn the concepts of turbine power. Students will identify the raw materials and structures required to build a gas turbine. Students will learn how to use measuring tools and instruments. Students will learn how to safely use basic hand tools. Students will learn how to safely use power tools. Students will learn how to use CAD software to create the parts of a gas turbine. Students will learn how to use CAD software to create a gas turbine assembly. Students will learn how to create the parts necessary to construct a functional small scale gas turbine. Students will learn how to assemble the parts of a functional small scale gas turbine. Students will learn how to safely start and operate a small scale gas turbine. Students will learn turbine monitoring and turbine management principles. Students will construct a functional gas turbine engine. TARGET TEAM ACTION Students will design, build, and operate a gas turbine using materials provided. CONTEXT Sixteen special needs students (language processing issues) enrolled in Technology, Engineering Design course that meets 68 minutes per period four times per week. No academic performance data will be available before class begins. This is a companion project that pairs with the EDP portion of the planned curriculum. This project will begin during the first academic quarter and continue until finished. This project will be the first exposure to shop tools and shop materials for most students. The project will be constructed from common household items and ordinary shop materials. These students will form the first cohort that will be tracked to take the Technology/Engineering MCAS (instead of the Biology MCAS) as part of their high school graduation requirements. BARRIERS The relevant IEP data will not be available prior to first day of class. Accordingly, there is no way to plan any important accommodations until the project is underway. Final approval of this projects rests with administration after reviewing safety criteria. Project will be evaluated on the following accomplishments: Creation of a turbine housing; Creation of a turbine shaft and shaft mounts; Creation of several turbofans with shaft attachments; Creation of fuel injection mechanism; Creation of a fuel ignition systems; Creation of a throttle mechanism; Creation of a starter mechanism; Creation of a turbine operator manual; and Creation of a gas turbine that runs for at least 3 seconds Issues that prevent reaching goal. LESSONS LEARNED The benefit of using the EDP to organize a project. The benefit of using CAD applications to refine the design process and to source materials and components. How to work in teams to design a subassembly. How turbines work. How to organize teams to create discrete components that function when assembled.
