Zeppelin Mania

This past Tuesday I wrote about the flight of the world’s first airliner — the LZ-7 Deutschland.

That post was a prelude to a series I’ll be writing throughout the rest of the year chronicling the triumphs of the rigid airship. More commonly known as the zeppelin, after Count Ferdinand von Zeppelin who built the first successful rigid airship.

Airship Types

There are three types of airship. Here is a diagram:

The earliest type was non-rigid, what we call a blimp today. There is no framework to maintain the shape of the envelope. The shape is maintained by gas pressure.

The second type of airship is the semi-rigid, like the new Zeppelin NT. The semi-rigid has a frame to maintains the length. Gas pressure maintains the width.

The third type is the rigid airship. The shape of the envelope is held in place by a framework. The lift gas is contained in bags (called cells) within the framework.

Why The Rigid Airship Is Better

The problem with non-rigid and semi-rigid airships is that they cannot be built large enough to be commercially viable. Blimps proved of value in anti-submarine warfare in World War II, but they and semi-rigids can’t carry sufficient cargo to be of large scale commercial use. The new semi-rigid Zeppelin NTs are basically used for advertising and sightseeing excursions.

The rigid airship solves the problem. The frame provides shape and strength and can be scaled up as large as the vessel needs to be. The rigid airship made the dream of long-range strategic bombing and intercontinental flight a reality.

Tomorrow is a double anniversary: the first flight of the first zeppelin and the start of the first east-west crossing of the Atlantic by air and the first round trip trans-Atlantic flight by an aircraft. An auspicious day indeed!

So get a glass of bubbly ready. Tomorrow we party!

Comments are always welcome. Until next time, happy reading!

The Wonderful Machine Age: The Daring Young Men in Their Flying Machines #3

The time period between World War I and World War II was the heyday of the rigid airship. Those two decades were filled with the exploits of what the great airships did and the dreams of what the future might hold for air travel.

1919 was an auspicious year. The war to end all wars was over. The airplane had developed in technological leaps and bounds. The airship as well had been refined. And whereas the airplane was mostly still a toy or of use for short distance flights, the airship was viewed as a machine of great commercial and military value.

On the 6th of March 1919, the British rigid airship, R33, took its first flight. Eight days later, her sister ship, R34, made it’s inaugural flight. Both airships were based on the design of German zeppelins in 1916. It is interesting to note, these were the most successful of any British rigid airship. The R33’s career lasted for nine years before she was scrapped in 1928 due to severe metal fatigue in her frame.

The R34 made the first east to west crossing of the Atlantic by air (the more difficult crossing due to the prevailing westerly winds) in July 1919, flying from England to Canada. Hot meals were even served on board, courtesy of a hotplate welded to an engine exhaust manifold. On the 13th of July 1919, the R34 returned to England; completing the first ever round trip across the Atlantic by air.

The flight of the R34 in 1919 fueled speculation of the possibilities for commercial airship flights across the Atlantic on a grand scale.

August 20, 1919 saw the first flight of the LZ-120, Bodensee, the Zeppelin company’s new commercial airship for the DELAG airline. She flew over 100 flights, carrying 2,322 passengers over 31,000 miles (50,000 km). Unfortunately, the Allied powers forced the Germans to turn over the Bodensee to the Italian government as a war reparations in July 1921. As the Esperia, she made flights for the Italian government, including a 1,500 mile long distance flight, before being scrapped in July 1928.

The Bodensee:

The LZ-121, Nordstern, never served the DELAG and was turned over to France on 13 July 1921 as war reparations. The French Government never made much use of the ship and she was scrapped in 1926.

A substantial book could be written chronicling just the airships of the interwar period. To exemplify The Wonderful Machine Age, I’ll focus on the triumphs and the dreams.

The short two year life of the R100 was a dream come true. The world’s first luxury commercial airship. Her first flight was on 16 December 1929. She and her sister ship, the R101, were, at the time, the largest airships ever built. She was meant to carry 100 passengers in elegance for an envisioned transatlantic passenger service. In 1930, she flew from England to Canada and back again; repeating the R34’s flight and proving once again the feasibility of such a transatlantic service. Below are pictures of the R100:

Unfortunately, with the crash and subsequent fire which destroyed the R101 on 5 October 1930, the R100 was grounded and then scrapped the following year. The British were no longer interested in rigid airships.

This left but three rigid airships flying: the German-built USS Los Angeles, the newly launched USS Akron, built by Goodyear-Zeppelin for the US Navy, and the Zeppelin Company’s LZ-127, Graf Zeppelin.

The USS Los Angeles was the US Navy’s most successful airship. She was a sturdy vessel, logging 4398 hours of flight time and flying 172,400 nautical miles (319,300 km) with no major incidents. She was a testimony to the superior engineering and craftsmanship of the Zeppelin Company. She was decommissioned in 1932, returned to service briefly after the crash of the USS Akron in 1933, and then once again mothballed. She was scrapped in 1940.

The greatest airship of all was the LZ-127 Graf Zeppelin. She was an experimental ship. To avoid valving off lift gas to compensate for fuel usage, the Graf’s engines burned Blau gas, which weighed about the same as air. This successfully innovative feature was not duplicated in any other airship.

The Graf was small compared to the R100 and R101. She only had room for 20 passengers. And while accommodations were pleasant, they were not sumptuous.

The Graf Zeppelin‘s career from 1928 to 1932 primarily involved experimental and demonstration flights displaying the airship’s capabilities. These flights included a round trip across the Atlantic in 1928, the round the world flight in 1929, the Europe-Pan American flight of 1930 (Germany to South America to North America and back to Germany), the 1931 polar expedition, two round trips to the Middle East, and a variety of other European flights.

The round the world flight set a world record. The Graf completed the circumnavigation in 21 days and could have made an even faster flight, except part of the purpose was a goodwill tour which involved spending extra time in Japan.

You can read more about her polar flight at airships.net.

Beginning in 1932 until she was retired in 1937 after the Hindenburg tragedy, the Graf provided regular passenger, mail, and freight service between Germany and Brazil. Below is my favorite picture of the Graf Zeppelin coming flying into Rio de Janeiro.

Zeppelin,Baia_de_Guanabara,25-5-1930

The Graf Zeppelin was the first aircraft to fly over 1,000,000 miles (1,056,000). She made 590 flights, 144 transoceanic crossings, carried 13,110 passengers, and logged 17,177 hours of flying time. She did this without a single injury to passenger or crew. Keep in mind, her lift gas was hydrogen. Which I think proves beyond a shadow of a doubt, with the proper precautions, hydrogen is safe. She was scrapped in 1940.

The Hindenburg is well known and I won’t cover her story here. Her sister ship, the LZ-130 Graf Zeppelin (II) took her first flight on 14 September 1938. Like the Hindenburg, she was designed to fly using helium as her lift gas. However, the US government reneged on its promise to deliver helium to the Germans and the Graf Zeppelin II was inflated with hydrogen. She never entered commercial service and made but 30 flights. On 20 August 1939 she made her last flight. When she landed at 9:38 PM, the era of rigid airship flight came to an end.

The rigid airships were the largest aircraft to fly. The success of the R33 and R34, the Graf Zeppelin, the USS Los Angeles, and the R100 excited the depression beleaguered public that good things were coming. Science and technology would make life better.

Lester Dent’s Zeppelin Tales and the fictional Doc Savage’s use of an airship were exciting fantasies reflective of this new hope that better times were coming.

The May 1930 issue of Modern Mechanics featured an airship with pontoons (to help cut hangar costs) and the July 1929 issue of Modern Mechanix, featuring an airship with wings and boat hull (to combine the best features of airships and seaplanes), were further examples of the possibilities that airships provided to improve intercontinental transportation.

There were even thoughts of an airship tuberculosis hospital. See airships.net for the article.

The airship has and continues to excite our imaginations as no other flying machine. Is it any wonder our retro-futurist fiction continues to make our dreams reality, even if only within the realities of our imaginations.

8 Sentence Sunday on Dieselpunks #11

Today’s snippet picks up from last Sunday’s. Inquiring minds wanted to know what Dru and Dunyasha were going to do with their pistols. Today we find out. The Argo, which is the former USS Los Angeles, is under attack by a pair of Soviet built biplanes. The airship is inflated with hydrogen, which makes for a potentially dangerous situation. But as Dru points out, it is difficult to shoot down a hydrogen filled airship. Everything has to be just right.

So here is today’s snippet. Once again, Dru and Dunyasha are in the thick of the action.

A second biplane appeared and opened fire, the bullets hitting above us.
“They’re going for the gas cells,” I said.
“Operation Barbecue,” Dunyasha shot back.
“Probably not. It’s pretty difficult to shoot down an airship. Even one filled with hydrogen.”
I took careful aim and, as the plane banked to avoid hitting us, emptied the magazine of the Sauer. Dunyasha did likewise with her Luger. A futile attempt.
