Why was weight a primary factor in the Wright Flyer's design?
Why was weight a primary factor in the Wright Flyer's design?
- Lightweight materials were easier to source and work with given the limited technology available.
- Heavier materials were more expensive at the time, making lightweight options more cost-effective.
- Lightweight materials allowed for greater speed and maneuverability, crucial for early flight experiments. (correct)
- The focus on lightweight materials was primarily for aesthetic reasons, as the Wright brothers prioritized appearance.
What was the main purpose of applying oils and finishes to the early woven fabric coverings of aircraft?
What was the main purpose of applying oils and finishes to the early woven fabric coverings of aircraft?
- To protect the fabric from the elements and prevent sagging. (correct)
- To increase the fabric's flexibility for easier manipulation during construction.
- To enhance the fabric's color and provide a more appealing visual appearance.
- To reduce the fabric's weight, further improving the aircraft's performance.
What was the primary advantage of using nitrate dope on aircraft fabric in 1916?
What was the primary advantage of using nitrate dope on aircraft fabric in 1916?
- Enhanced ability to repel water and prevent mildew growth.
- Reduced weight compared to earlier fabric treatments.
- Improved fabric adhesion, tautness, and protection. (correct)
- Increased resistance to impacts and tears during flight.
Why was butyrate dope eventually combined with nitrate dope for aircraft fabric treatment?

Study Notes
- The Wright flyer used a fabric-covered wood frame.
- Using fabric provides the advantage of light weight.
- The disadvantages of using fabric are poor durability and flammability.
- Finely woven organic fabrics, like Irish linen, tended to sag, exposing the structure to the elements.
- Builders started using oils and finishes to protect the fabric.
- In 1916, nitrite dope became available to make fabric adhere, taut, and protect it.
- However, nitrite dopes had the extreme flammability.
- Butyrate dope was determined to be less flammable
- This second type of dope did not adhere well.
- Eventually the two dopes were combined.
- First nitrate was applied then butyrate.

Description
The Wright flyer used fabric-covered wood, chosen for its light weight. Fabric has issues like poor durability, flammability and sagging. Protective oils and finishes were adopted, and later, nitrite dope was used for adhering and protection, but this was extremely flammable.
