1. 1 Composite Generator Enclosure PROJECT 99.12 New Castle Design Associates

2. 2 Composite Generator Enclosure Team 12 Justin Schaffer Tom Winward Noel Goldstein Jeremy Freeman Members: Customer:Center for Composite Materials Advisor:Dr. Michael Keefe Mission: It is our goal to design and construct a prototype portable generator enclosure made from composite materials that successfully satisfies all the wants and constraints defined by our customers, and to have a prototype built by April 1999. Approach: We will first identify customers and their wants. We will also attempt to find all current technology in the field in order to have a basis for comparison with our project. Then concepts will be generated using information gained from our benchmarks. By comparing our concepts with customer wants and constraints, we will determine the best design. We will then begin a process of prototype design and evaluation, culminating with the production of a prototype part.

3. 3 Background Army needs portable generator for use in remote locations D-Star Engineering designing lightweight diesel engine CCM contracted to build enclosure

4. 4 Needs Being Met Need for a highly portable generator Need for sound reduction of engine Need for highly durable enclosure

5. 5 Benefits of a Solution Increased safety to troops using generator due to lower noise level More pleasant operating atmosphere Less human resources required to transport it Long-run monetary savings
