Background Information
Most of Boeing design aircrafts are affected by
corrosion.
How do they prevent corrosion?
Process of preventing corrosion- sealing and
curing.
The two current approaches of sealant are
known as “traditional” and “lean” methods.
Advantages and disadvantages of each method.
Traditional Method
•Advantages:― Hold many parts.
― Has humidity control.
•Disadvantages: ― Large Size, costly to move.
― Hardwired/Plumbed.
― Inefficient flow control
Lean Method
• Advantages:― Proper size and
flow.
― Not hardwired.
― Apply 120v AC
•Disadvantages
: ― No humidity
control.
― Plumbed.
MISSION STATEMENT
• Design a device which can embrace the
advantages of the two current methods together to
produce a highly efficient curing oven.
• Equip the current oven with a non-corrosive,
humidity control and maintain a lightweight design.
• Design oven will have on board water supply.

Technical Risk Management
Scope Definition:
• A “scope control process” will be maintained
throughout the lifetime of the project.
Performance:
• Performance of each team member will influence
directly to the success of the product.
Reliability:
• The product must be reliable since it utilizes on a daily
basics. Identify the design’s weaknesses and eliminate
or minimize their effects.
