2. Engineering Contexts
• We can look at designs of anything in
terms of their context.
• What made these objects the way they
are?
– Roman Aqueducts
– Pyramids of Egypt
– Nintendo DS

3. Things to Consider
• What is going on in history?
• What is the need?
• What problems does the need create?
• What customers will want to buy the
product?
• How much money do they have?
• What technology is needed to make it happen?
• What are the resulting products?

4. Keep Asking “Why?”
• Why do objects look the way they do?
• What made them like that?
Let’s Look at
Aerospace Vehicles

5. Why Would You Use a Seaplane?
• Land on water
– Patrol
– Fishing
– Submarine hunting
• What is unique about these aircraft?
• Why aren’t these components on all aircraft?
• Wouldn’t it be nice to always have the option to
land on water?

6. Why Would You Use a Helicopter?
• Land and take off vertically
– Saving lives
– Delivering supplies
– Maintaining law and order
– Maneuvering into small locations
• What is unique about these aircraft?
• Why can’t all aircraft do this?
• Wouldn’t it be nice to always have the option to
land vertically?

7. Why Would You Use a Sailplane?
• No motor
– Recreation
– Assault (WWII assault gliders)
– Returning space shuttles
• What is unique about these aircraft?
• Why can’t all aircraft do this?

8. Why Would You Use an Airship?
• Lighter-than-air gases are
added to a big bag to provide lift
– Carry large payloads
– Fly quietly
– Advertisements
• What is unique about these
aircraft?
• Why can’t all aircraft do this?

9. Why Would You Use a Rocket?
• High speed and high-power
transportation both within the
Earth’s atmosphere and in space
– Military
– Research
– Launching probes and satellites
– Space travel
• What is unique about these
aircraft?
• Why can’t all aircraft do this?

10. Why Would You Use a
Hot Air Balloon?
• Powered by fire and has a
parachute like design to help it
fly.
- Attraction
- Aircraft
- Photos

11. Why Would You Use an Airplane?
• Fixed-wing aircraft that is
propelled forward by thrust from a
jet engine, propeller, or rocket
engine.
- Transportation
- Fast Travel
- Cargo Transportation

12. Why Would You Use a
Rocket or Space Shuttle?
• a cylindrical projectile that can be
propelled to a great height.
- Space Exploration
- Facilitates Human Spaceflights
- Launch Satellites

13. Why Would You Use an
Unmanned Aerospace Vehicle
(UAV)?
• An aircraft piloted by
remote control or onboard
computers
- Capture Footage
- Entertainment purposes
- Fast
