7th Grade Engineering Technology

Homework


Mar 23-27: Continue using FoilSim to design an airfoil. Finish Control Surface worksheet. Due Friday.
Continue with presentation, complete with visual aids, that discusses the following:
  1. The three axes of motion for an airplane
  2. The control surface on an airplane that controls motion in each axis (just the major ones)
  3. The overall purpose of an airfoil (Hint: go back to Bernoulli again).
  4. Some groups also need to explain which control in the cockpit controls each of the surfaces mentioned in #2. For example, if the rudder controls yaw, what does the pilot do in the cockpit to move the rudder.
We will present to a 3/4 class on Wednesday morning, April 1st. Rubric is here.

Final Project due at the beginning of class on April 15th, 2015:
Research your chosen airplane (as listed on the class board 3/25/15). Find all specifications, including the weight of the empty airplane and the full capacity weight, wingspan, overall length, etc. You and your partner must determine the pressure difference needed to make the plane fly expressed in pounds per square inch (PSI). Show all work. Load your final project to the wiki (preferred) or turn in a hard copy.

Mar 16-20: Continue using FoilSim to design an airfoil. Begin work on Control Surface worksheet.
Develop a presentation, complete with visual aids, that discusses the following:
  1. The three axes of motion for an airplane
  2. The control surface on an airplane that controls motion in each axis
  3. The overall purpose of an airfoil (Hint: go back to Bernoulli again).


Presentations will be made to third and fourth graders. Rubric for grading will be provided.

Mar 9-13: Begin working FoilSim Lift to Drag ratio worksheet.

Mar 2-6: First rotation: Present to Mrs. Butzin's third and fourth graders. Post a reflection on how you think it went. Second rotation: Begin simulation activities.


Feb 9-13: Begin working on a quality presentation that thoroughly and in detail discusses the following:
  • The forces involved in flight (i.e., thrust, lift, weight, drag). How do they affect flight? What causes them?
  • Overall airfoil shape - Explain Bernoulli's Principle and how it affects the shape of an airfoil. Why is lift created? How is it created? How can this be used in other activities?
  • Shape and size of an airfoil. Why are the different surfaces of the airfoil shaped the way they are? How do the different surface shapes affect lift and drag (i.e., look at the lower surface, is it flat, concave, convex?). How does size (height, length) affect lift and drag?

You will have a total of three class periods to work on this presentation.


Jan 26-30: None
