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
