Introduction to the AIAA Educator Academy Electric Cargo Airplane Module Tom Milnes

Webinar Overview The Engineering Challenge of Tethered Flight Costs and Financing Curriculum Module AIAA Workshops Available Capstone Event

Goals and Objectives Today’s Webinar will: Introduce you to the concept and utility of a tethered flight engineering challenge  Design, Build, and Fly for HS and MS students Convince you that materials are available to excite students about STEM via this challenge Convince you there is available training for you to execute the concept in the classroom / after school Inform you about resources for putting together a Capstone Competition

Genesis Module stems from the Maryland Engineering Challenges Electric Cargo Challenge  Run by AIAA Mid-Atlantic Section for almost 2 decades at the Baltimore Museum of Industry –  Middle School and High School Levels of Competition Key Aspect  Designed to be run indoors without expensive Radio Controlled equipment

Tethered Flight Concept Tether Power Pole Power Supply Packing Tape

Challenge Plane flies empty 1 lap at least 8” off ground Plane then flies with weight added 1 lap at least 8” off ground Cargo Weight = Plane with Cargo – Plane Empty Plane that carries the most weight wins the performance component  Scores scale by weight

Challenge Components Performance – 30 points Written Report – 30 points Oral Interview – 20 points Design Evaluation – 20 points

2 nd Place Winners!

1 st Place Winners

Costs – Reusable Items Reusable Items – 1 per teacher  Power Pole –Kelvin $ –  16V DC Transformer –Kelvin $125 – Potential funding with AIAA Educator Grant Program  Currently $250 per teacher, 2 teachers per school per year –  Should also contact your local AIAA section for support

Cost – Consumable Items Cost per plane for a proven foam wing design is < $10  With team of 4 student < $2.50 a student

Curriculum Module Contains a 5 week lesson unit plan for the classroom to prepare for  An in-class competition  An external competition

Curriculum Module – National Standards Correlation to National Standards  Science Standards K-8,9-12  National Education Technology Standards for Students (NETS·S)  National Math Standards K-12  National Languages Arts Standard K-12

Curriculum Module – Glossary of Airplane Terms Airplane Terms  aileron, airfoil shape, airspeed, angle of attack, area, aspect ratio, balance, chord, coefficient of lift, density, drag, elevator, empennage, flaps, fuselage, horizontal stabilizer, landing gear, lift, motor, planform, quarter chord point, rudder, span, stall, swept back angle, stall, taper ratio, thrust, vertical stabilizer, weight, wing

Curriculum Module – Background Information for Educators Historical Perspective on Flight Uses NASA Engineering Design Process for Secondary Students

Curriculum Module – Week Identifying the Problem 2 - Identifying Criteria and Constraints Learning the STEM Content  History of flight  Parts of an airplane  Forces on an airplane –Lift, Weight, Thrust, Drag  Basic airfoils  Angle of attack and stall  Wing geometry (span, chord, area, aspect ratio, taper ratio) for rectangular, elliptical, and trapezoidal planforms.

Curriculum Module – Week Brainstorm possible solutions 4 - Generate ideas 5 - Explore possibilities 6 - Select an approach Design Aspects  Main Wing – Most Important  Fuselage and landing gear – consider stock solution  Empennage (Tail) – consider stock solution

Curriculum Module – Week Build a Model or Prototype

Curriculum Module – Week 4 Fly With Cargo  Use leader board to build excitement

Curriculum Module – Week Refine The Design  Adding cargo weight and attempting to fly with the new cargo  Modifying their wing (e.g., reshape or add flaps)  Designing and constructing an entirely new wing  Modifying the fuselage/landing gear/empennage assembly  Trying a different propeller –Gear motor for greater torque with larger propelor Communicate Your Results!  Written Report  Oral Presentation

Cracking The Code Not all teachers will feel comfortable with all aspects of an Engineering Challenge  Science and Math Teachers will understand the STEM Content but not how to build airplanes  Tech Teachers may know how to build airplanes but not feel comfortable with STEM Content  Some after school programs are run by dedicated but overwhelmed Liberal Arts teachers A workshop demonstrating the module in practice is highly helpful!
