Introduction to the AIAA Educator Academy Electric Cargo Airplane Module

Tom Milnesthomas.milnes@jhuapl.edu

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– http://www.thebmi.org/page/maryland_engineering_challenges

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

2nd Place Winners!

1st Place Winners

Costs – Reusable Items

• Reusable Items – 1 per teacher Power Pole

– Kelvin 851508 - $199.95 – www.kelvin.com 16V DC Transformer

– Kelvin 841051 - $125 – www.kelvin.com

• Potential funding with AIAA Educator Grant Program Currently $250 per teacher, 2 teachers per school per year

– https://www.aiaa.org/Secondary.aspx?id=4184 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 1

• 1 - 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 2

• 3 - 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 3

• 7 - Build a Model or Prototype

Curriculum Module – Week 4

• Fly With Cargo Use leader board to build excitement

Curriculum Module – Week 5

• 8 - 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!
