Blimps are essentially non-rigid structures, that is they are generally mainly composed
of a single large, flexible gas-bag supporting a gondola with controls and an engine.
The gas-bag is filled with gas, usually helium, to attain flight. This gas can be vented
or increased to change altitude. The Goodyear blimps are a very good example of this
type of aircraft.
=================================
All of the gas-filled flying things ... blimps, zeppelins, dirigibles, hot-air balloons,
party balloons, etc. ... are called "lighter-than-air" craft, and that should be your
first clue. Each of them is lighter than the same volume of air. It floats in air for the
same reason that a lighter-than-water object floats in water ... by being lighter than
an equal volume of whatever substance it's floating in. That's a less scary way of saying
that its aggregate density is less than the density of the surrounding fluid. Any object
surrounded by fluid is held up by a force equal to the weight of the fluid that it pushes
out of the way. If it pushes aside enough fluid to weigh more than the object itself does,
then the object rises, as sure as a beach-ball pops up from the bottom of the pool.

What is buoyancy and how does it affect a blimp?
buoyancy is a measure of how well an object will float in a given medium, eg: a boat in water. similarly for a blimp, the blimp is the object, the air is the medium. if it is not buoyant enough, it will not 'float' in the air, aka fly
What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Why do things float in the air?
things float in air because of density
Why do hot air balloons float in the air?
Hot air rises and the fire in the hot air balloon wants to go up and float in the air and since it's can't escape the balloon the fire just brings the balloon with it to float in the air
How does a flame enable a hot air balloon to float?
Because it heats the air and of course the hot air will rise above the cold air causing it to float!

Is it true to float in air a blimp could be filled with helium?
Yes
Can a blimp filled with helium float in the air?
Yes, it can. Just as helium balloon will.
Is it true or false that to float in air a blimp could be filled with helium?
False
How does a blimp stay up in the air?
Helium Buoyancy--- This is the same thing that allows boats to float on water. The boat displaces a volume of Water and if the weight of the Boat is lighter than the weight of the displace water, then it floats. This is same with Blimps or Dirigibles. The Blimp is filled with Helium. The volume of the helium inside the blimp is lighter than the weight of the voume of air that it displaces so it rises. When the blimp reaches the higher altitude where the air is thinner (and therefore lighter) then the blimp will stop rising. At this altitude the weight of the blimp EQUALS the weight of the air it displaces.
How does blimp fly?
A blimp is a version of a dirigible, it is non-rigid and is kept in shape only by the hydrogen or helium inside it. those are the only gases lighter than air, so they float through a high-oxygen atmosphere. a blimp is usually propelled through the air by a large fan.
Are aircrafts the same as ships?
No, ships float on the sea, aircraft fly in the air. NO similarity.
Why are all airplanes aircraft but not all aircraft are airplanes?
An aircraft is any vehicle made for air transportation: plane, blimp, balloon, etc.An airplane is one of many types of aircraft, one that uses a plane (wing, airfoil) to get its lift. Therefore, all airplanes are aircraft, but not all aircraft are airplanes.
What has more mass a hot air balloon or a blimp?
blimp
What best describes the force of atmospheric pressure on a blimp?
An air compressor blowing gasses into the blimp is what causes the air pressure in the blimp. These gases are lighter than air.
Can a blimp filled with carbon dioxide float?
It can, if you fill the balloon with air and let it float on the carbon dioxide. We used to do this with soap bubbles to illustrate certain effects of surface tension (for example, the fact that bubbles of the same size form a planar interface, but the interface between bubbles of different sizes bulges towards the larger bubble, proving the pressure in the smaller one is higher... it's much easier to see this when the bubble isn't actively falling towards the floor as you're trying to observe it). Put a piece of dry ice in the bottom of a large bath jar, and allow the bubbles to float on the denser carbon dioxide layer in the jar. Filling a balloon with carbon dioxide, though, will not cause it to float, as carbon dioxide is denser than air.
Do you need any special training or a license to drive a blimp or any other lighter-than-air aircraft?
The rules are basically the same for any kind of aircraft, except if you're flying a balloon you don't need a medical certificate. You have to train for a certain amount of hours in the kind of aircraft you are seeking a certificate to fly, and you need to bring a working example of that kind of aircraft to your FAA practical test. As far as WHERE you get the training...it's pretty much on-the-job training. If you want to fly the Goodyear Blimp you need to come in with an Air Transport Pilot certificate and thousands of hours in multiengine aircraft before they'll look at you.
