Rigid dirigibles have a framework that contains gasbags, usually 3-5 , these provide the 'lift' . The outer skin is just for streamlining. They usually have 2-4 aircraft motors powering propellers to move them in the air.
Count Ferdinand von Zeppelin invented the first practical dirigibles in the late 1800's but he didn't fly the first ones till about 1910. There were previous balloons called dirigibles, but they did not have a frame.

Yes, helicopters are not airplanes. I think hot air balloons are considered flying. Also, people fly on hang gliders. Dirigibles are not airplanes.
No, airplanes need wings for lift. - Now having said that, aircraft can fly without wings, as they include helicopters, dirigibles and balloons which have alternate ways of gaining lift.
Dirigibles is pronounced as "dir-i-juh-buhls" with the emphasis on the second syllable.
What are the two famous dirigibles
Dirigibles are lighter-than-air aircraft that can be maneuvered by their own power. There are different kinds of dirigibles, such as blimps and airships, but all are distinguished from other lighter-than-air craft, such as balloons, which do not have their own steering and power sources.
Dirigibles typically use helium as the gas for buoyancy because it is less flammable than hydrogen, which was used in the past. Helium is a non-reactive, safe, and abundant gas that allows dirigibles to achieve lift.
Today, dirigibles are commonly referred to as airships. This term encompasses various types of lighter-than-air aircraft, including blimps and zeppelins, which are characterized by their buoyancy and ability to navigate through the air. Airships are used for various purposes, such as advertising, surveillance, and tourism, due to their ability to fly slowly and at lower altitudes.
All three are types of lighter-than-air aircraft that rely on buoyancy to fly. They also have a balloon-like structure filled with a gas that is less dense than the surrounding air. However, hot air balloons specifically use heated air to generate lift, while blimps and dirigibles are powered by engines for propulsion.
Dirigibles were not used in Ww2 London. Barrage balloons however were. See Related Links below.
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.
