Rationale:

MGHS’s Aeronautical Velocity Challenge focusses on engaging students with Science Technology, Engineering and Mathematics. It involves aeronautical design, flight, testing, racing and DESCTRUCTION. Students compete in teams of three to five students to design, produce, test and evaluate their prototypes. Teams are required to justify their design and engineering decisions. In addition students will produce individual engineering design portfolios of their work.

Learning Activities:

Students will complete a range of activities including;

  1. Forming small groups and organising management of the project
  2. Researchinga wide range of aeronautical concepts
  3. Producing a standard Skylap plane design, testing and modifying.
  4. Designing and producing an innovative Skylap plane which will fly the fastest and highest
  5. Producing an individual engineering design portfolio
  6. Testing, racing and dog fighting a custom madebalsa Skylap plane.

Assessment Activities:

A)Team

  1. Form teams of three to five members, mixed gender teams are encouraged.
  2. Research as many aspects of aerodynamics, flight, aircraft design, as possible in order to be able to design a model Skylap aircraft made from balsa. Concepts could include:
  • Bernouli’s principle
  • Venturi Effect
  • Newton’s Third law
  • Lift, thrust, weight and drag
  • Lift to drag ratio
  • Angle of attack
  • Angle of incidence
  • Control surfaces
  • Wing tip vortices
  • Wingtips
  1. Produce a standard Skylap plane design using the instructions provided. Test the plane, make multiple modifications in order to produce a plane which is fast and will fly the highest.
  2. Your team will then design and construct a new plane using only the materials originally provided.
  3. The finalSkylap plane should be tested and results of which used to improve the overall performance of the plane.
  4. In your testing you need to record speed and distance over five laps. Also record maximum height obtaining.
  5. The Skylap plane will be assessed for the quality of its engineering, manufacture and for technical merit.
  6. Finally you will complete a dog fight where you need to chase other planes with a ribbon attached to its tail. The first plane to touch the other teams ribbon will be the winner. Several heats will be conducted in order to decide the overall winner.

B)Individual

  1. Produce an engineering design portfolio with no more than 20 printed pages (including cover pages). The portfolio should include information on the following;
  • A title page
  • Scope of the Profession
  • The nature and range of work completed by aeronautical engineers
  • The training required to become an aeronautical engineer
  • What job opportunities are there for aeronautical engineers in Australia
  • Aeronautical Engineering Concepts:- see above for examples
  • Idea Generation – e.g drawings of Skylap design concepts, with annotations
  • Evidence of testing: what did you find, what did you modify and how did it work
  • Calculations/Graphing: students are to determine speed, distance travelled, height achieved during various tests. These results should be presented in a series of graphs and tables
  • Evaluation: design ideas and final solutions
  • Bibliography
