Helium is sold by the US Government for 1.5 cents per cubic foot; annual production is about 5 million cubic feet. In bulk, it is sold in 2500 psi cylinders, each containing 5600 cubic feet of helium when released. A few industrial-scale users within the US receive helium in tanks 40' long, 4' in diameter, sent four to a flatcar -- each tank contains 200,000 cubic feet of helium. A transatlantic dirigible voyage results in the loss of about 5% of the lifting gas (more or less depending on conditions, construction techniques, and crew skill). Hydrogen is usually produced at airship bases as needed, rather than being stored in large quantities. 


LZ 127 Graf Zeppelin

  •     German hydrogen-filled dirigible, 45 crew + 20 passengers + 12 tons cargo; five 530 HP Maybach engines; cruise 72 mph, endurance 118 hours; length 774', diameter 100', weight (empty) 74 tons; launched 1928; visited America (including a stop in Los Angeles) during 1929 round the world trip. Cost, 7.5 million Marks -- about $1,800,000.


USS Los Angeles ZR-3

  •     American helium-filled dirigible, crew 40 - 45; five Maybach 400 HP engines; top speed 76 mph. Length 658', diameter 90' 8". Originally the German LZ-126, this ship was obtained as war reparations in 1924 and used to test various systems and procedures for the later Akron and Macon, including some that were not used (or not publicly acknowledged), such as glider-landed troops. Decommissioned in June of 1932, it was announced in 1939 that she would be dismantled.


USS Macon ZRS-5

  •     American helium-filled dirigible; eight Maybach engines of 560 HP; top speed 70 mph; length 785', diameter 133'. Carries up to five Sparrowhawk fighter aircraft aboard. Its sister ship USS Akron (ZRS-4) was lost in April of 1933. They cost about $4 million each.



  •     British hydrogen-filled dirigible, 30 to 45 crew + 100 passengers, carried in 3 decks (cabins are two or four berths each, and accomodations include a 56 person dining room); engines six Rolls Royce Condor V-12, 650 HP each; max 131 mph, range about 8,000 miles; length 720', diameter 136', hull weight 59 tons empty, fuel and oil 32 tons, water ballast 21 tons, gross lift 175 tons (mass of airship, cargo, fuel, crew, ballast, etc.); cost $900,000. First flight was on December 16, 1929.

The blimp word of the day is "monometer."
