Die LA Times hat einen langen, ausführlichen Artikel über die Saturn V-Trägerrakete und ihre Konstrukteure, die Buzz Aldrin, Neil Armstrong und Michael Collins auf den Mond schoß, und der ist voller purem Rocketporn.
The Saturn V design called for five first-stage F-1s to burn kerosene for 2.5 minutes, after which five second-stage J-2 rockets, using a brand-new fuel, liquid hydrogen, would propel the spacecraft to 15,600 miles an hour and an altitude of 109 miles.
The third stage, consisting of a single J-2 engine, was to burn for 2.5 minutes, placing the craft in a parking orbit around the Earth. Several hours later, the engine would ignite again and burn for six more minutes, setting the linked command and lunar modules on course for the moon at 25,000 miles an hour.
Everything about the Saturn V was big, including its appetite. Fueling it required 89 truckloads of liquid oxygen, 28 trailer-loads of liquid hydrogen, and 27 rail cars full of kerosene.
But envisioning a monster like the Saturn V and making it work were two different things. The greatest challenge was the biggest engine, the F-1. Eighteen feet tall and weighing 9 tons, it was designed to be 10 times as powerful as any previous rocket.
"A 10% upgrade is significant in engineering terms," said Biggs, a bearish, bespectacled man of 75. "A factor of 10 puts it in a whole new universe."
