Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
Airships are usually the shape of a oval. They look like blimps. Airships are usually filled with helium to keep them afloat.
blimps are oval shaped
Blimps are non-rigid airships with an envelope that maintains their shape, while dirigibles are semi-rigid or rigid airships with a structure inside the envelope to maintain their shape. Dirigibles are typically larger and have more internal structure for support and control.
There are some companies which produce remote controlled blimps. West Coast Blimps & Electronics, Yoshioka Model Factory, DraganFly Innovations Inc., and Model Airships and Blimps produce remote controlled blimps
Blimps are non-rigid airships. Their shape is determined by the design of the envelope (inflatable bag). Most common airships are shaped like a cigar.
Blimps, or airships, were primarily manufactured in various countries, including the United States, Germany, and the United Kingdom. Notable production sites included Goodyear in the U.S., which built many commercial and military airships, and the Zeppelin factories in Germany, known for their iconic designs. In addition, smaller manufacturers and enthusiasts have produced blimps in different regions around the world.
As soon as aircraft (and that includes airships and blimps) were capable of carrying bombs. There were many air raids in WWI.
Size and type of gas contained in the envelope.
Airships are also, and more commonly, known as zeppelins. The term airship is also used to refer to an airplane, but this usage is incorrect, as they have two different meanings. Airships might also be called blimps or dirigibles.
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
An airship without a frame is called a "blimp." Unlike traditional rigid airships, blimps maintain their shape solely through internal pressure from the gas inside, typically helium or hydrogen. This design allows for greater flexibility and lighter weight, but also limits the airship's ability to carry heavy payloads compared to framed airships. Blimps are often used for advertising, surveillance, and recreational purposes.
