A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874 and developed in detail in 1893. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word zeppelin came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins as bombers and as scouts, killing over 500 people in bombing raids in Britain.
An airship, dirigible balloon or blimp is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air.
R101 was one of a pair of British rigid airships completed in 1929 as part of a British government programme to develop civil airships capable of service on long-distance routes within the British Empire. It was designed and built by an Air Ministry–appointed team and was effectively in competition with the government-funded but privately designed and built R100. When built, it was the world's largest flying craft at 731 ft (223 m) in length, and it was not surpassed by another hydrogen-filled rigid airship until the Hindenburg flew seven years later.
The R.38 class of rigid airships was designed for Britain's Royal Navy during the final months of the First World War, intended for long-range patrol duties over the North Sea. Four similar airships were originally ordered by the Admiralty, but orders for three of these were cancelled after the armistice with Germany and R.38, the lead ship of the class, was sold to the United States Navy in October 1919 before completion. On 24 August 1921, R.38 was destroyed by a structural failure while in flight over the city of Hull. It crashed into the Humber Estuary, killing 44 out of the 49 crew aboard. At the time of its first flight it was the world's largest airship. Its destruction was the first of the great airship disasters, followed by the Italian-built US semi-rigid airship Roma in 1922, the French Dixmude in 1923, the British R101 in 1930, the USS Akron in 1933, the USS Macon in 1935, and the German Hindenburg in 1937.
His Majesty's Airship R100 was a privately designed and built British rigid airship made as part of a two-ship competition to develop a commercial airship service for use on British Empire routes as part of the Imperial Airship Scheme. The other airship, the R101, was built by the British Air Ministry, but both airships were funded by the Government.
R.36 was a British airship designed during World War I, but not completed until after the war. When she first flew in 1921, it was not in her originally intended role as a patrol aircraft for the Royal Navy, but as an airliner, the first airship to carry a civil registration (G-FAAF).
The R.33 class of British rigid airships were built for the Royal Naval Air Service during the First World War, but were not completed until after the end of hostilities, by which time the RNAS had become part of the Royal Air Force. The lead ship, R.33, served successfully for ten years and survived one of the most alarming and heroic incidents in airship history when she was torn from her mooring mast in a gale. She was called a "Pulham Pig" by the locals, as the blimps based there had been, and is immortalised in the village sign for Pulham St Mary. The only other airship in the class, R.34, became the first aircraft to make an east to west transatlantic flight in July 1919 and, with the return flight made the first two-way crossing. It was decommissioned two years later, after being damaged during a storm. The crew nicknamed her "Tiny".
The R.80 was a British rigid airship, first flown on 19 July 1920 and the first fully streamlined airship to be built in Britain. Originally a military project for the British Admiralty, it was completed for commercial passenger-carrying purposes. R.80 proved too small for this role and after being used briefly to train the United States Navy personnel who were to crew the ill-fated ZR-2 airship, R.80 was retired and eventually scrapped in 1925.
A rigid airship is a type of airship in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company.
The 23 class were rigid airships produced in the United Kingdom during the First World War. Development of the 23 class began in August 1915 when Vickers was asked to improve the 9r design by increasing its gas capacity by adding a bay and increasing the capacity of the bow and stern gas cells. The 23-class was designed by H.B. Pratt and Barnes Wallis of Vickers. Vickers built the first and last of the four ships. The other two were built by William Beardmore and Company and Armstrong-Whitworth. While the 23 class airships were never used in combat, the four ships provided many hours of valuable training and experimental data for British airship crews and designers. Although a total of 17 of these ships were contemplated at one time, only four were ever built. The 23 class was found to be significantly overweight, leading to its cancellation in favour of the more-refined R23X class.
Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellors for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965.
The British Imperial Airship Scheme was a 1920s project to improve communication between Britain and the distant countries of the British Empire by establishing air routes using airships. The first phase was the construction of two large and technically advanced airships, the R100 and the R101; the R100 made a successful transatlantic crossing to Canada in 1930 in 78 hours. The scheme was terminated in 1931 following the crash in France of R101 in October 1930, while attempting its first flight to India.
The DN-1 was the US Navy's first airship. Captain Mark L. Bristol, the second Director of Naval Aviation, supported the development of the dirigible in the anti-submarine role. Victor Herbster, Holden Richardson and LCDR Frank McCrary drew up the specifications for the DN-1. The contract was awarded on 1 June 1915 to the Connecticut Aircraft Company of New Haven, CT. The U.S. Navy had no experience with airships and it seems neither had any of the principals of Connecticut Aircraft Company. They were a lawyer who was the financial backer, an amusement park owner who acted as manager; the technical staff was an Austrian, Hans Otto Stagel, who claimed to be a dirigible pilot and a German engineer and mechanic, who claimed to be Zeppelin experts. Jerome Clarke Hunsaker of MIT and his assistant Donald Wills Douglas, later founder of the Douglas Aircraft Company, aided the Connecticut Aircraft Company in the design of DN-1. The Chief Engineer was James F. Boyle and the Production Manager was J.J. DeLunay. The civilian inspector was Thomas Scott Baldwin and the resident Navy inspector was Frank M. McCrary.
The Zeppelin LZ 1 was the first truly successful experimental rigid airship. It was first flown from a floating hangar on Lake Constance, near Friedrichshafen in southern Germany on 2 July 1900. "LZ" stood for Luftschiff Zeppelin, or "Airship Zeppelin"
His Majesty's Airship No. 1 was designed and built by Vickers, Sons and Maxim at their works in Barrow-in-Furness, Lancashire, England, as an aerial scout airship for the Royal Navy. It was the first British rigid airship to be built, and was constructed in a direct attempt to compete with the German airship programme. Often referred to as "Mayfly", a nickname given to it by the lower deck, in public records it is designated ‘HMA Hermione’ because the naval contingent at Barrow were attached to HMS Hermione, a cruiser moored locally preparing to act as its tender.
The British R.23X class of rigid airships were developed during World War I using the experiences gained from the 23 class, but only two of the planned four R.23X class were built: R.27 and R.29. Both were completed mid-1918, but just two-and-a-half months after entering service R.27 was destroyed by fire in a hangar; while R.29 went on to become the most successful British wartime rigid airship, being the only one to meet enemy action, as well as the only one to sink a submarine.
LZ 18 was the second Zeppelin airship to be bought by the Imperial German Navy. It caught fire and crashed with the loss of all aboard on 17 October 1913 before entering service.
The Zeppelin P Class was the first Zeppelin airship type to be produced in quantity after the outbreak of the First World War. 22 of the type were built as well as 12 of a lengthened version, the Q Class . They were used for many of the airship bombing raids on the United Kingdom in 1915-16, for naval patrol work over the North Sea and Baltic and were also deployed on the eastern and south-eastern fronts.
The Zeppelin R Class was a type of rigid airship developed by Zeppelin Luftschiffbau in 1916 for use by the Imperial German Navy and the German Army for bombing and naval patrol work. Introduced in July 1916 at a time when British air defences were becoming increasingly capable, several were lost in the first months of operation, leading the Germans to reconsider their technical requirements and eventually to develop airships capable of bombing from a greater height. Most surviving examples were modified to meet these requirements, by reducing weight at the expense of performance. A total of 17 were built.
