LEVIATHANS of the Air (Oct, 1930)


Germany, forbidden to construct military planes, has turned her attention to commercial craft. The world had no sooner recovered its breath from viewing the Dornier “DO. X” than Junkers announced a plane which would carry 175 tons.

    Hmm. That Dornier D.O.X sort of reminds me of the airplane in the movie Non-stop New York, made in 1937. Check it out here: http://www.archive.org/…

    Private cabins. More or less like a small ship in the air!

    D.O.X. looks like an inflated version of the china clipper. But for the time why 12 motors of only 500hp??? Wasn’t there better available?

    Why does the flying wing look like it’s going backwards?

    David Johnson: Because it’s meant to be flying away from you like the other 3 planes illustrated. Note the contrails of the trailing edge of the wings which also hold the ailerons. The elevator function is handled by the canard wing extending in front of the crew cabin.

    The DO X did indeed have 12 engine sof 524 hp each but these were later replaced by 610 hp engines

    TomLR: Enjoyed the movie. See what you mean. From recent taxing and runway problems with the growing size of planes, next generation larger airports are demanded. Also more reliance upon existing technology will replace functions done by human controlling minds that tend to sleep between the arrivals of fewer planes since these giants transport more in less trips.

    TomLR, thanks for the link. I watched it all the way through, and it was fascinating, not in the least because it assumed that this airliner had as much space as an ocean liner! Loved the observation deck with a low railing for safety in 150 mph breezes.

    The takeoff on water was so smooth that the female lead had to inform the male protagonist that they were taking off, since he hadn’t noticed as they wandered about the stateroom.

    WW II was a major reality in 1938, but not in this film!

    Mcubstead: Engine outputs stayed pretty low until the advent of high-octane fuel in WWII. You couldn’t use the kinds of high compression ratios needed to get high horsepower without the engine destroying itself in short order due to detonation. Back then gasoline was what we now call “white gas” and had an octane rating of about 50!

    Tetra-Ethyl-Lead entered wide spread use in 1924 as an octane booster and anti-knock agent. The Allison V-1710 engine was introduced in 1930, the model of 1931 could produce 1000 horse power on 100 octane gasoline.
