Objective: To research, brainstorm, design, construct, and test a rubber band glider that will meet the designated challenge(s).
Criteria for Glider:
-Glider must be constructed of multiple parts that fit together to make one
-All parts must fit on a Makerbot Replicator + print tray and print in one sitting
-Minimal amounts of external material can be used (printer paper, masking tape, and paper clips)
-Must have a slot to be launched using a rubber band
With a partner (for this section only), complete the FlipGrid RenneTalk. Go to the website: https://info.flipgrid.com/ and use the code eccd3d to access the directions. Read and complete this activity. You will be submitting more than 1 video. You can use props to help demonstrate concepts if needed. NO PowerPoints, Prezis, or Google Slides. You will be graded the same way as your previous RenneTalk so the more creative and engaging you make it the better it will be!
You can also download the FlipGrid app on your phone and use your phone to record your videos. My computers will not work for this assignment so you will need to use your school issue laptops (or your phones). If you have any issues please let me know ASAP.
Individually sketch 10 different rubber band glider ideas on blank computer paper. Each sketch must include orthographic and isometric views of the glider. It might be a good idea to research airfoils and utilize that information in your designs. I should be able to clearly understand what the design looks like from these sketches. If you want to add any notes or dimensions to help understand the sketches better, feel free to.
A program that you can download and use at home is at the following website: https://www.grc.nasa.gov/www/k-12/airplane/foil3.html - this allows you to simulate airfoils and calculate lift and drag values to see what design works the best. You can download it at home on a personal computer (not the school issued laptop). I will continue to work on making it available in the classroom.
Decision (March 28)
After reviewing your sketches and utilizing the airfoil program, decide on the best design and circle it on your paper to designate that it will be your final.
Design and Construct
In Inventor, create all of the individual parts you will need to construct your glider. Place each part into a template and print it (each sheet should have the front, top, right, and isometric views). Create an assembly drawing of your gilder and place that in a template and print it. Create an exploded drawing of your glider and place that in a template and print it. These drawings should be the exact copies of what you are printing so you might want to do the 3D prints first before printing out all of the parts on templates
Take all parts and convert to STL files for 3D printing. You will be completing 2 prints. The first print will be printing all of your parts at ½ scale. When you are ready to 3D print, see Mrs. Renne and provide her with the estimated time to print all your parts. Upon approval, she will give you the flashdrive for the Rennebots and allow you to start printing. Once all of the parts have printed, construct your glider to ensure that the parts will fit together.
Make adjustments if necessary and resave STL files. The second print will be at full scale. When you are ready to 3D print, see Mrs. Renne and provide her with the estimated time to print all your parts. Upon approval, she will give you the flashdrive for the Rennebots and allow you to start printing. Once all of the parts have printed, construct your glider to ensure that the parts will fit together.
Do a final construction of your glider adding any adhesive or external items allowed (if needed).
Gliders will be launched from the same launch line one at a time using the same rubber bands. Launches will be recorded on the Recording Worksheet and then discussed after each student has completed 2 launches.
