Worksheet and Rubric PDF

Objectives

  1. Create a nose cone for a paper/tape rocket
  2. Hypothesize about how your nosecone will make your rocket fly
  3. Modify your design, as necessary meet manufacturing needs

shapes

Deliverables:

  1. (6) Brainstormed designs
  2. (1) Inventor .ipt file
  3. (1) .stl 3D Mesh File
  4. (1) “A” sized drawing sheets showing the three sides and isometric views of the nosecone.
  5. (1) paper and tape rocket with your nose cone attached
  6. (1) altitude testing worksheet
  7. (3) reflections one for each section

Constraints:

  1. Base of the nosecone should be a cylinder ∅21.33mm x 5mm tall
  2. Maximum bounding cylinder is ∅25mm x 60 mm tall
  3. Minimum wall thickness is 1mm

   

steps

Steps of nose cone creation Inventor:

  1. Create the ∅21.33mm circle and extrude it 5mm:

    step 1
  2. Create a sketch of the profile of your nose cone:

    step 2
  3. Revolve Profile to complete shape:

    step 3

Consider the following and respond accordingly, you may hand write this or type it on separate sheet:

Brainstorming & Exploring Reflection Prompts

  1. What types of jets/rockets did you look at, how did they influence your design?
  2. What is the story of one of your artistic ideas, where did it come from or what did you try and mimic?
  3. Please describe your rockets first flight/what is your prediction for how it fly?

Protyping Reflection Prompts

  1. What were 2 challenges you had in creating your nose cone?
  2. Why is it important to follow the constraints? If you don’t follow them, what can happen when your design is printed/flown?

Refine Reflection Prompts

  1. What changes did you need to make to your design before/due to manufacturing (3D printing)?
  2. Was your hypotheses about your flight correct? If not please describe how it was different.
  3. What changes would you make to your design if you were to repeat this exercise?
