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.
