The goal of the Cargo Airplane Challenge is to design and construct an electrically-powered model aircraft to fly a tethered flight of at least one lap without cargo, followed by a second tethered flight of one lap carrying as much cargo as possible. The design is limited only by the specified motor and power supply, and the maximum dimensions of 3 feet.
To meet the requirements of this challenge your team should:
Define the Problem
Read these rules. Pay particular attention to the constraints.
Write a brief synopsis of the task in your engineers notebook.
Ask questions as needed for clarification.
Research the Topic
Attend the lessons concerning the STEM associated with this challenge.
Reseach airplanes and aerodynamics using the internet and other resources.
Now that you have done everything, why not enter the Maryland Engineering Challenges? The Cargo Airplane Challenge will be held on Sunday 8 March 2018.
This challenge involves four main components: the design and construction of the project, a written report, an
oral report, and the performance demonstration.
Design and Contruction (30 Points). Your airplane will be evaluated on the achievement of design specifications, creativity of structural design, quality of construction, and finished enhancements.
Written Report (20 Points). Provide a written report in the Maryland Engineering Challenge format. Be sure and include information is all of the required sections, as well as your design sketches, etc.. The report will be evaluated based on content, organization, style, and presentation (form, format, mechanics, and visuals). A rubric is available.
Oral Report (20 Points). Provide a 5 to 10 minute techncial briefing explaining how your team designed your entry and the underlying scientific principles. In class, you may use a 4 slide PowerPointtm. At the statewide competition the only visual aid that you can use is your airplane.
Performance Demonstration (30 Points). Your performance will be based on the weight of your cargo. The highest cargo weight will receive 30 points. Any airplane that flies will receive at least 18 points (in class).
In class, the tether will be 7 feet long. At the state-wide challenge the tether must be long enough so that the distance from the power pole center point to the plane's centerline is at least 10 feet.
A lap will be considered successful when the plane flies at least 8" high continuously for a complete circle.
No more than two minutes will be allowed for any attempt.
Cargo may not have lift-increasing or drag-reducing properties for the airplane as a whole.
No lighter-than-air devices or commercial kits are permitted.
