Initial Research Pathway:

  1. The team was looking for the top produced commercial Aircraft in history.
  2. The team used Goggle to find out more about commercial aircraft.
  3. The team utilized Wikipedia to understand the overview of commercial aircraft.
  4. The team used ChatGPT to find out on the people choice of commercial aircraft with the prompt best commercial aircraft in the market.
  5. The team selected the Boeing 787 Dreamliner.
  6. The team utilized ChatGPT to find out the features and function of Boeing 787 with the prompt list out the features and function of Boeing 787 Dreamliner
  7. The team utilized Google search engine to understand Boeing 787 different model. 
  8. The team went through the Boeing website to find out more about the specifications of the Boeing 787 dreamliner. https://www.boeing.com/commercial/787
  9. I looked up 

1. Used ChatGPT to better understand the Boeing 787-8’s wing design and its key features.

  • Search Output: Learned about the aerodynamic design of the Boeing 787-8, including its raked wingtips, high aspect ratio, and the use of carbon fiber reinforced plastic (CFRP) for weight reduction. ChatGPT also provided insights into the fuel efficiency benefits and challenges in manufacturing CFRP wings.
  • Keyword Search: “Boeing 787-8 wing design overview,” “features of Boeing 787-8 wing,” “Boeing 787-8 CFRP advantages and challenges.”

2. Searched Google Scholar for more academic information on the Boeing 787-8’s aerodynamic efficiency.

  • Search Output: Found academic papers discussing how the 787-8's raked wingtips and high aspect ratio wings contribute to reduced drag and improved fuel efficiency. These sources highlighted that the use of CFRP in the wing structure offers weight savings of around 20% compared to traditional aluminum, leading to a significant reduction in fuel consumption.
  • Keyword Search: “Boeing 787-8 fuel efficiency,” “raked wingtips aerodynamic efficiency,” “CFRP wing materials aviation.”

3. Decided to focus on a comparative analysis of the Boeing 787-8 and Airbus A350, with an emphasis on long-haul performance and aerodynamic innovations.

  • Search Output: Looked at comparative studies that highlight the fixed raked wingtips of the Boeing 787-8, which provide a better lift-to-drag ratio and improved performance at higher altitudes over long distances. In contrast, the Airbus A350’s adaptive winglets are better suited for varied flight conditions but may not be as efficient on extended long-haul routes.
  • Keyword Search: “Boeing 787-8 vs Airbus A350 aerodynamic comparison,” “Airbus A350 adaptive winglets performance,” “long-haul aircraft wing efficiency.”

4. Explored manufacturing and maintenance challenges related to the Boeing 787-8’s composite wings.

  • Search Output: Reviewed reports on the challenges of using CFRP materials in wing construction. Found details on the higher production costs (estimated to be 10-15% more than traditional wings) and the specialized techniques required for CFRP maintenance and repairs, which involve advanced tools and processes.
  • Keyword Search: “Boeing 787-8 composite wing manufacturing challenges,” “cost of CFRP in aircraft wings,” “CFRP maintenance and repair aviation.”

5. Searched for case studies on fuel savings and operational cost benefits linked to the Boeing 787-8’s wing design.

  • Search Output: Discovered case studies showing that the Boeing 787-8’s wing design reduces fuel consumption by around 20%, contributing to substantial long-term operational savings for airlines. These studies also discussed how the reduced carbon emissions associated with the 787-8’s aerodynamic efficiency enhance its value for environmentally-conscious airlines.
  • Keyword Search: “Boeing 787-8 fuel savings long-haul routes,” “environmental impact of Boeing 787-8,” “Boeing 787-8 operational cost savings.”

6. Reviewed online sources on turbulence reduction and passenger comfort improvements due to the Boeing 787-8’s flexible wings.

  • Search Output: Found online articles and studies explaining how the Boeing 787-8’s flexible wings, enabled by CFRP materials, absorb up to 30% of turbulence, leading to smoother flights and improved passenger comfort. This was compared to the Airbus A350, which also uses composite materials but lacks the same level of wing flexibility for turbulence reduction.
  • Keyword Search: “Boeing 787-8 flexible wings turbulence reduction,” “passenger comfort Boeing 787-8 vs Airbus A350,” “Boeing 787-8 wing flexibility.”
