My favorite, and not just because I worked for a (completely unrelated)
division of Rockwell, is the hydrogen fuel turbopump for the Shuttle
Main Engines. It's considerably more expensive than a Jetta, and far
less useful in commuting, but it's very impressive.
Not much larger than a car engine, it develops 69,040 horsepower. IIRC,
that's done with 122 titanium turbine blades, each weighing about an
ounce. That's about 565 HP each. And it goes from 0 to 37,000 RPM, and
from a few degrees above absolute zero to around 600 degrees C in about
a second. The discharge pressure is enough for 36 miles of 'head', at
least for liquid hydrogen.
Cheers,
Wayne
Got me under pressure.
