And in the light rain…
I visited the National Museum of Nature and Science★
It’s comfortable since it’s just one line on the Hibiya Line, but… there are many stations, and beyond Roppongi gets tiring.
They had a special exhibition called “Sky and Space,” so I went to see it.
Anzani air-cooled radial three-cylinder, 25 horsepower
Salmson 9Z water-cooled radial nine-cylinder, 230 horsepower
Lorraine water-cooled V-12, 400 horsepower
Sakae Type 21, Ha-115 engine, 1,000 horsepower
I wondered why they use the term “radial”?
The horsepower contest is won by the engine monster
V2500 turbofan engine★
Wow!
