Study Notes
Introduction to Fuel and Lubricants
- Aviation fuel is crucial for aircraft engine performance and development, paralleling other technological advancements in aviation.
- Pioneering efforts in aviation fuel began in the 1930s, led by influential figures recognized for their contributions in research and development.
History of Fuel
- Fuel usage dates back 2 million years with Homo Erectus using sticks and wood for fire.
- 3,500 BC: Evidence of charcoal usage as fuel discovered in Southern Europe and the Middle East.
- 2,500 BC: Coal burning documented in China for cooking and heating purposes.
- 2,000 BC: Charcoal became widely used in British bronze production, reaching temperatures over 1000°C.
- 1 AD: Crude oil was first collected and refined in China for lamps.
- 1600-1700s: British innovate by cooking coal into coke, a significant fuel source for industries in subsequent centuries.
Key Figures in Aviation Fuel Development
- Major Jimmie Doolittle was instrumental in advocating for aviation fuel advancements before WWII.
- Advocated for high-octane aviation gas, leading to the creation of 100-octane fuel, known as Aviation Gasoline (AvGas).
- Doolittle's efforts ensured the U.S. had sufficient high-quality fuel at the onset of WWII, enhancing aircraft performance over German counterparts.
Octane Ratings and Fuel Efficiency
- Fuel rating is based on the octane level; higher octane ensures efficient combustion in piston engines.
- Before Doolittle's advocacy, most gasoline had an 87 octane rating, inadequate for powerful piston engines used in military aircraft.
- The development of high-performance fuels spurred advancements in aircraft engine technology.
Learning Outcomes
- Recognize the historical context and technological advancements related to aviation fuels.
- Understand the significance of individual contributions to fuel development in aviation.
Enrichment Activity
- Assess the historical timeline of fuel invention and notable contributors to aviation gas developments through structured writing.
Essay Rubric Overview
- Evaluates organization, content, critical thinking, development, and grammar, highlighting levels from inadequate to exemplary in scholarly writing.
