It might be Helium.....symbol He. But I'm not sure.
abosolutley nothing. Bacon. Blimp. Cheese. And riding around!!
The duration for which a blimp's envelope stays inflated can vary depending on factors such as the quality of the materials used, maintenance practices, and environmental conditions. Typically, modern blimps are designed to retain their inflation for several days to weeks before requiring additional helium or air. Regular inspections and repairs are essential to ensure the envelope remains airtight and operational for extended periods.
Lieutenant Jean Baptiste Marie Meusnier (1754--93) of the French Army came up with the idea. It's been through a lot of changes and improvements leading to rigid airships (Zeppelins after Count Von Zeppelin their most famous builder) and the modern "Blimps" non-rigid airships. Albert Caquot's R-Type Balloon is probably the forerunner of the classic blimp shape - used by basically every army for allsorts of stuff.
Hot air balloons were primarily used for entertainment, scientific experiments, and military reconnaissance in the 1700s and 1800s. They were not very practical for transportation because of their limited control and reliance on favorable wind conditions.
Both, a balloon and a blimp, are considered aircraft, and fall under the category of "Lighter Than Air Aircraft" as regulated by the F.A.A. They both have a huge bag of some sort of gas that is lighter than the air around it, and therefore creates lift. Since the Hindenburg, Helium has been the lifting gas of choice, as it is an inert gas, therefore safe and manageable. Some balloons use hot air for lift for shorter, less expensive flights. Suspended from this bag, called the "Envelope", is the passenger compartment. This "Gondola" or "Car" also houses the Pilot, and controls for the aircraft. That is where the similarity of the two part ways. To simplify the big difference, balloons climb quite readily, but have no means of propulsion, therefore primarily drift in the ambient air. Their path and destination are determined by how the Pilot uses the existing winds. Most times the winds travel at different directions in different altitudes and your Pilot will navigate using these variations to the destination. Truly, an artform. However, if the entire air mass is moving to the east, guess what? You are going east. On the other hand, a blimp has engines and propellers, and therefore is steerable, even against the wind, to the destination. Blimps almost always land at airports, whereas, balloons almost never do. In other words, blimps operate like other aircraft for point-to-point navigation, only slower, and lower. With balloons, you are blissfully and romantically casting your fate to the wind. A finer, more elegant, adventure is hard to find.
The element that is used in the Goodyear blimp and other dirigibles is helium. This gas is lighter than air and causes the blimp to rise.
Helium
Helium, a lighter than air gas, is used for buoyancy in the Goodyear Blimp. Hydrogen has not been used for many decades because of the explosive danger.
In 1925, the first commercially available blimp was built, the Goodyear Pilgrim. It was also the first to be used for public relations. This blimp started the Goodyear Santa Claus Express program where each December the company would decorate it to celebrate the season.The first Goodyear Blimp, the Pilgrim, was first flown in 1927.
Helium is the answer if you don't believe me go on Wikipedia and search blimp.
Several blimps (Goodyear and Fuji) are used at sporting events and can be seen either live or on TV.
I think It is either helium or air Ans 2 = Blimps were made of rubberised fabric, a true blimp had no frame. Framed airships, also called 'dirigibles' had a light metal frame and 'gas bags' of rubberised fabric within the frame . Almost all of both kinds used helium as a lifting medium
Dirigibles were not used in Ww2 London. Barrage balloons however were. See Related Links below.
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.
No. All three are so-called "lighter than air" machines, because they're filled with gases that make tham buoyant in normal atmosphere. But the gases are different. The Hindenburg was filled with hydrogen, and was destroyed in 1937, in a catastrophe so deadly and so graphic that hydrogen was never again used to float airships. Blimps today, including the Goodyears, are floated with helium. And hot-air balloons, as the name implies, are floated with . . . . .
Only at GoodYear locations
So the blimp will stay aloft/still adn will float.
