The bagel they save for the regulars. Don't skim, savour.
Summary
This article explores the engineering and materials science behind modern jet engines, focusing on the innovative casting techniques that produce single-crystal turbine blades. These blades can withstand extreme temperatures of up to 2,000 degrees Fahrenheit, enabling jet engines to operate with unprecedented efficiency. The article traces the history of jet engine development from the first flight in 1939 to today's global aviation fleet, explaining how advanced metallurgy and clever manufacturing processes have pushed the boundaries of what's possible in aerospace engineering.
Key quotes
· 4 pulledThe very first flight powered by a jet engine took place in Germany on August 27, 1939.
Now most of the 19,400 airplanes in the global air-transportation fleet are jets, with about 5 million passengers boarding them every day.
On heavily traveled North Atlantic routes between North America and Europe, there are about 800 flights daily; it is possible for a passenger to reach almost any part of the planet within a day.
Clever casting techniques produce jet engines that can withstand 2,000-degree temperatures, allowing unprecedented efficiency.
