2. What is engineering?
Engineering - The branch of science and technology concerned with the design, building, and use of engines, machines, and structures.
2. Engineering - the discipline dealing with the art or science of applying scientific knowledge to practical problems
Discuss what it means to be an engineer and what might be expected on an engineer.

3. Different Types of Engineering
Aerospace Engineering
Mechanical Engineering
Material Engineering
Environmental Engineering
Computer Engineering
Civil Engineering
…ETC

5. Aviation Design
How does it tie into engineering?

6. Aviation Design
Teaches real principles and practices used in modern engineering
Utilizes up to date software to design and draft aircraft
Experiences reviews from professionals in the field.
Learn hands on techniques of construction that can be universally applied.
Receive direct feedback from student driven education

7. Jobs!!
Everyone wants a jobs. Why else go to school for 5 years?….(plug in for swep, inroads, career services )
Everyone wants a job why else go to school for five years? You want to make the big money? Well I just went over what I consider the sales rep for this class, now lets discuses what you’ll really be getting.
Make budget ….. Give price of all there supplies so only really budgeted item is wood…. (possibly allow advantages such as carbon fiber rods to thrifty teams)
Talk about why its good to talk to faculty (let of recommendation, research , job opportunitys)

8. Perks Extra curricular activity
Experience working in groups to accomplish a goal
Possibly leadership experience.
Experience in a competitive setting
Practical use of a CAD software of choice (solidworks or ProE)
Drafting experience

Drafting experience
Experience making a build of materials (BOM)
Experience with a budget
Potentially a plaque in the engineering building
Recognition my facility

10. Even More Perks! Experience making a build of materials (BOM)
Experience with a budget
Potentially a plaque in the engineering building
Recognition by facility

11. Basic Overview of Class Layout
Students will split into groups of 3-4 and work together.
Each group will be assigned a number. They will then be responsible for picking a team caption. (group names are optional, but encouraged if witty)
Each group will be allowed to compete in two out of three missions listed on the syllabus
To complete missions groups will be responsible for designing, drafting and constructing a model aircraft that is capable!

12. Your Missions Mission 1 - Ferry Flight
A test of your planes speed and maneuverability
Mission 2 - Passenger Flight
A test of your planes ability to carry passengers safely while maintaining weight efficiency
Mission 3 – Payload drop
An optional third mission with a High reward but drastic consequences in terms of points if failed.
See page 2 of syllabus for complete listing of rules

13. Overview of what will be covered in today's class
How an Aircraft Flies
Lift
Thrust
Drag
Airfoil Terminology
Induced drag
Total drag
Drag curve
Start teaching here but do not form groups untill second class…..

14. How a Plane Flys
Fight between four forces shown. Thrust from engine…lift from pressure difference…drag …..weight due to gravity

15. Lift
Lift is generated as air flows over wing….due to farther distance draveled and viscuse affects lift is generated ….(research more)…..not always up from ground….

16. Thrust

17. Drag Induced Vs parasite wing over surface Induced
Drag is caused by friction on surface….viscuseness of air….. Bigger surface more friction….always opposite direction motion…. Two kinds…. Parasitic and induced.

18. Drag
Drag is caused by friction on surface….viscuseness of air….. Bigger surface more friction….always opposite direction motion…. Two kinds…. Parasitic and induced.

19. How an Airplane Moves

20. Aircraft Terminology
Give quiz at end of class….make sure they have access to these two pictures or handbook.

21. Examples ….elevator up
Plane of motion?
How has the plane reacted?

22. Examples ….rudder left
Plane of motion?
How has the plane reacted?

23. Example ….left aileron up
Plane of motion?
How has the plane reacted?

24. Aircraft Airfoil Terminology
The camber line is a curve starting and ending at the same points as the chord, but where each single point is equidistant from both the top and bottom surface

25. Engineering challenge !
Work in groups of four and come up with a solution to the following problem
At this point students will form groups of four and come up with what they believe to be the best solution.

26. Overview of today's class
Center of Pressure
Center of gravity
Determining the center of gravity
Mean aerodynamic cord
Wing Design
Low wing
Mid-wing
High aspect ratio
Low aspect ratio
Straight wings
Swept wings
Forward swept
Back swept

27. Center of Gravity
Total weight is assumed to be where the lift vector is…if CG moves forward or back? Flat spin stall

28. How to find CG
Work equation on bored. Then make several other examples to check understanding of students. Afterwards explain methods used in field post construction to get CG

29. Wing Design Wing design follows these general steps:
1. Estimate the aircraft’s weight.
2. Select a wing loading based on performance goals.
3. Calculate wing area based off of wing loading.
4. Select an aspect ratio based on performance goals.
5. Determine wing span.
6. Choose a wing planform.
7. Determine chord lengths.
8. Choose a dihedral angle and calculated tip height.
9. Select an airfoil section.

30. 1. Estimate the Aircraft’s Weight
Take an estimate of all the required components for the aircraft to fly
E.X. Cargo, fuel, landing gear, engine, fuselage weight…etc
See excel sheet in dropbox labeled list of parts

31. 2. Select a wing loading based on performance goals
Wing loading is the amount of force per area
Most R.C. planes range between .75 lb/ft^2 to 1.5 lb/ft^2 or 12 oz/ ft^2 to 24 oz/ ft^2

32. 3. Calculate Wing Area Based off of Wing Loading
Can be calculated by; W/S= Wing Loading
Where;
W= weight
S= surface area

33. 4. Select an Aspect Ratio Based on Performance Goals.
Higher aspect ratios result in long thin wings
Lower aspect ratios result in short stubby wings
Typical aspect ratios for RC airplanes are between 5 and 8

34. 5. Determine wing span
Can be calculated by AR = b2/S using previously determined AR

35. 6. Choose a wing planform

36. 7. Determine chord lengths
Various kinds as shown to left
Elliptical
Constant
Tapered

37. 8. Choose a dihedral angle and calculated tip height.
Typical dihedral for RC airplanes are between 0 and 6 degrees

38. 9. Select an airfoil section
See excel sheet in dropbox labeled Equations sheet when picking airfoil

39. Engineering challenge !
Work in groups of four and come up with a solution to the following problem
Original design
Easier new design
Again have groups form in teams of two and begin the Engineering challenge…. These will be the teams that will compete.
What’s wrong with the new design?
