2008 Senior Engineering Design Projects Wind-Solar Hybrid Energy System Designers: Michael Dell, Jonathan Siemen, William Tanis Sponsors: Messiah College Department of Engineering, Carl Erikson Advisor: Carl Erikson In the global pursuit of cleaner energy, many are turning to the conversion of freely–available wind and sun energies. A wind–solar hybrid energy system uses the availability of both resources in one versatile and convenient package. Small wind and solar systems are quickly gaining popularity and, in combination, present an affordable, clean, and effective solution for household energy needs. Using a small wind turbine and solar array along with batteries for energy storage, the team designed the system to offer consistent power in spite of less–than–ideal wind and sunlight conditions. With a comprehensive, detailed display and custom designs for a barn application, the system is not only practical but user-friendly and easy to maintain.
Designers: Ben Jordan, Nick Kipe, Tyler Thumma Sponsor: The Collaboratory for Strategic Partnerships and Applied Research Advisor: Barbara Ressler In many parts of Africa, the supply of energy is sporadic and unreliable. Due to this and the demanding cost of energy, The Theological College of Zimbabwe and the Collaboratory are working together to more efficiently design solar hot water heaters, which will reduce energy expenses in developing countries. Further developing a project from 2005, our team focused on verifying the existing theoretical model of the solar collector panel. In addition to accurately modeling the output water temperature of the panel, we also focused on building testing prototypes, defining the limits of the model, and tabulating manufacturing techniques.
Alternate Aviation Solutions 2008 Designers: Jeffrey Eng, Nathan Horst, Jonathan Patrick Sponsors: The Collaboratory for Strategic Partnerships and Applied Research, JAARS, Mission Safety International, Mission Aviation Fellowship Advisor: Harold Underwood Small-scale mission aviation departments depend on flight–tracking and communication technologies for the safety of their pilots and the advancement of their ministry. As commercial solutions are rapidly increasing in price, AAS 2008 has sought to provide a low cost alternative in adapting the Automated Flight Following System, developed by JAARS, to interact with the line of Codan radios currently employed by Mission Aviation Fellowship. Built on the dependable backbone of high frequency radio communication, this solution would serve a fleet of 134 aircraft in 51 locations worldwide.
Personal Electronic Math Tutor Designers: Jeremy Ashinghurst, Scott Eshleman, Phil Gilde Sponsor: The Collaboratory for Strategic Partnerships and Applied Research Advisor: David Gray, Angela Hare Through conversations with local teachers on previous service trips to Mahadaga, Burkina Faso, the Collaboratory’s Education Group learned that students in the region are proficient at reciting factual arithmetic but have difficulty applying this to real situations. In an attempt to assist Mahadaga’s teachers with this problem, our team designed and created a handheld personal electronic math tutor suited for the severe West African environment. The tutor teaches visual object recognition and object–based mathematics, such as addition and subtraction, through the use of a keypad and LCD screen.
Village Water Ozonization System Designers: Ian Leslie, Gerald Mwangi Sponsor: The Collaboratory for Strategic Partnerships and Applied Research Advisor: Ariela Vader, Timothy Whitmoyer There is a critical need for clean water in parts of rural Honduras. The VWOS team has
Light Sport Aircraft Engine Integration Designers: Joshua Joyce, Tyler Miller, Jonathan Shenk Sponsors: ROTAMAX, Messiah College Department of Engineering, Messiah College Flying Club Advisor: Donald Pratt For the past few years the Messiah College Flying Club has been designing and building a Light Sport Aircraft (LSA) to provide an inexpensive alternative to currently available production aircraft. This two-seat airplane is designed for applications such as medical missions in remote locations, pilot training, and general utility. Our project incorporated the LSA fuselage with the engine and drive train produced by previous senior projects. Specifically, we developed an appropriate engine mount, cooling system, and exhaust system, as well as engine instruments and engine cockpit controls.
Light Sport Aircraft Control Systems, Landing Gear, and Folding Wings Designers: David Brown, Brian Dahl, Dustin Jefferies Sponsors: Messiah College Flying Club, Messiah College Department of Engineering Advisor: Donald Pratt For the past few years the Messiah College Flying Club has been designing and building a Light Sport Aircraft (LSA) to provide an inexpensive alternative to currently available production aircraft. This two-seat airplane is designed for applications such as medical missions in remote locations, pilot training, and general utility. Our project’s focus was on the creation of the dual control system, landing gear, and wing folding mechanism of the airplane. The priorities in design were low cost, durability, simplicity, and ease of use.
Designers: Joseph Barcelona, Christopher Burd, Robert Effinger Sponsor: The Collaboratory for Strategic Partnerships and Applied Research Advisor: Donald Pratt With an increased demand for alternative means of transportation, electric motors are becoming a more viable and practical power source due to their high efficiencies. Specifically, brushless DC motors have a wide range of applications, each one requiring different motor specifications. Our team developed a motor that allowed us to test various parameters which directly affect torque and RPM performance. From our testing data we then formulated scalability equations which allow motors to be built according to required specifications.
Scalable Brushless DC Motor Controller Designers: Steven Rosenshine, Ben Staudt Sponsor: The Collaboratory for Strategic Partnerships and Applied Research Advisor: Donald Pratt As the use of alternate energy sources is becoming more important, the adoption of electric motors is rapidly increasing. Motor controllers on the market today are either prohibitively expensive for resource limited developers or lack scalable functionality in diverse applications. A scalable controller that serves the needs of the Collaboratory’s electric tricycle project and the electric motorcycle project must be able to adapt for various sizes, power outputs, and configurations of the projects' motors. We have created a scalable motor controller capable of providing the flexibility and functionality of a high-end design with the usability and price of a simple design.
Designers: David Hostetter, Timothy Jones, Lucas Witmer Sponsors: The Collaboratory for Strategic Partnerships and Applied Research, Messiah College Department of Engineering Advisor: Carl Erikson Biodiesel, a renewable petrodiesel equivalent, performs well in unmodified diesel engines. The purpose of the project was to establish a crude palm oil based biodiesel manufacturing process for use in the Democratic Republic of Congo. To this end, the project team modified an existing biodiesel processor to improve safety and efficiency, developed a long-term plan for project sustainability, and developed refinement processes for Congolese palm oil.
