An airship is a type of lighter-than-air aircraft with propulsion and steering systems, it is used to carry passengers and cargo. It obtains its buoyancy from the presence of a lighter-than-air gas such as hydrogen or helium. The first airship was developed by the French, called a ballon dirigible, it could be steered and could also be flown against the wind.
TYPES OF AIRSHIP
Two basic types of airship have been developed: the rigid airship, the shape of which is fixed by its internal structure; and the nonrigid blimp, which depends on the pressure created by a series of air diaphragms inside its gas space to maintain the shape of its fabric hull. Inventors sought to combine the best features of these models in a semirigid type, but it met with only limited success. Today only the nonrigid airship is used.
The rigid airship\'s structure resembled a cage that enclosed a series of balloons called gas cells. These cells were tailored to fit the cylindrical space and were secured in place by a netting that transmitted the lifting force of their gas to the structure. Each gas cell had two or more valves, which operated automatically to relieve pressure when the gas expanded with altitude, the valves could also be operated manually so that the pilot could release gas whenever desired.
Also on board was a ballast system that used water as ballast. On the ground this ballast served to make the airship heavier than air. When part of it was released, the airship ascended to a cruising altitude where the engines supplied propulsion, and further ballast could be released to gain more altitude. As fuel was consumed, the airship became lighter and tended to climb. This was countered in hydrogen-inflated airships by simply releasing gas into the atmosphere.
The method was uneconomical, however, with helium-inflated airships, and they were therefore equipped with ballast generators, apparatuses that condensed moisture out of the engines\' exhaust gases to compensate for fuel that was consumed. But this ballast-generating equipment was expensive, complex, heavy, and difficult to maintain and was thus one of the most serious disadvantages of airships filled with the safer but more expensive helium.
In contrast to the rigid airship, the nonrigid blimp has no internal structure to maintain the shape of its hull envelope, which is made of two or three plies of cotton, nylon, or dacron impregnated with rubber for gas tightness. Inside the gas space of the hull are two or more air diaphragms called ballonets that are kept under slight pressure, either by blowers or by air that is forced through scoops as a result of the forward motion (ram effect). The ballonets in turn exert pressure upon the gas, which fills the envelope, and this pressure in turn serves to stiffen the shape of the envelope and create a smooth flying surface. On takeoff the ballonets are almost fully inflated, but as the airship gains altitude and the gas expands, air is bled from the ballonets while a constant pressure is maintained throughout the envelope. When the gas contracts upon descent, air is pumped back into the ballonets.
HISTORY OF RIGID AIRSHIPS
The German company Luftschiffbau Zeppelin had the most success in building rigid airships. The first Zeppelin was flown on July 2, 1900; it was 419 ft long, 38 ft in diameter, contained 338,410 cu ft of hydrogen gas in 16 cells, and was powered by two 16-hp engines. Its range and payload were negligible. The last Zeppelin was the Graf Zeppelin II, which was first flown on Sept. 14, 1938; it was 803 ft long, 135 ft at maximum diameter, contained 7,062,100 cu ft of hydrogen, and was powered by four 1,050-hp Daimler Benz diesel engines. It could carry loads of 30 tons over transoceanic distances. It was scrapped in May 1940.
A total of 119 Zeppelins were built, most of them during World War I, when 103 airships were delivered to the military. The most famous Zeppelin was the original GRAF ZEPPELIN, which during 1928-37 made flights to the United States, the Arctic, the Middle East, and South America; it also made one

World War I Powers World War I Powers During World War I many different types of weapons were utilized by both the Allied and Central powers. Some were variations on older models of weaponry, and others were totally new inventions created to aid in the wartime effort. Most of the new weapons were used as killing machines in trench warfare, which was practiced during World War I, while others were employed as tools of espionage, scouting land areas, or air and sea warfare. Communication also played a major role in
The History of The Airship The History of The Airship Airships. In the early years of War, these beasts were known for their majestic presence in the sky and were icons of a country's power and prestige. They reigned mostly as reconnaissance and transport utility aircraft but there was something about this lighter-than-air ship that made it far more than a mere utility workhorse. In this essay, I will discuss the ever-popular and ever- living king of the sky; the Airship. Airships, or dirigibles, were developed from th

LZ-130 LZ-130 a.k.a. Graf Zeppelin II The Graf zeppelin II was the last of the airships to be built for the great German fleet. The Graf Zeppelin IIs size and shape were almost no different than her sister, the Hindenburg. The only noticeable difference were the Graf zeppelin IIs forward facing propellers. Most Zeppelins around the time of the Graf Zeppelin II had backward facing propellers used for pushing. The LZ-130 had propellers made for pulling. Even though The Hindenburg and the Graf zeppelin
WWII Strategic BombingWWII Strategic Bombing This essay will argue the success of the Allied strategic bombing campaign in World War II. In doing so this essay will argue that the initial inability of the Allied bombers, due to technical problems and a failure to dominate Germanys airspace, to deliver a bombing attack with precision on an enemies vital war making industries resulted in an initial failure of the strategic bombing tactic. Furthermore this essay will analyse the complete failure of the British strategy
World War I World War I Twenty-seven countries on five continents were involved in World War I. This war was also called the Great War or The War to End All Wars. World War I was the bloodiest and most costly of all the previous wars. The total casualties numbered thirteen million with another thirteen million wounded. The cost of this war was estimated to be more than $337 billion (Young World Book 364). World War I was different from previous wars because of the new types of weapons and methods used on t
History of Rock and Roll History of Rock and Roll In the early 50s, at the end of the big band swing era, came a form of music that, like others, parents would reject and their children would love. This type of music is known as Rock and Roll. Rock and Roll is defined as a popular type of music played on electric instruments and characterized by a strong beat and much repetition. Simply this means music that kids like, music that parents hate, and in some places banned from schools. Although there are many different t

BombsBombs A bomb is a container filled with an explosive, incendiary matter, or gas that can be dropped, hurled, or set in place to be detonated by an attached exploding device. It may range in design from a homemade device used by terrorists, assassins, or clandestine raiders to a sophisticated weapon of war. The original bomb, an ancestor of the hand-thrown GRENADE, was a simple container filled with black powder (see GUNPOWDER), which was set off by a fuse lit by the thrower. In the 16th century,
