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

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

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!
