Why Does a Blimp Rise?
A blimp is a small, balloon like airship, especially one used for observation or as a barrage balloon. A blimp rises because it is filled with a gas that is lighter than the air around it.
It depends on the pressure of the gas inside to keep it inflated to its normal shape. A blimp has engines to move it through the sky and controls for steering.
A control car holds the pilot and carries six passengers. The only blimps that fly regularly today are three blimps owned by the Goodyear Rubber Company. There are currently two blimps (non-rigid airships) and one semi-rigid airship in Goodyear’s U.S. airship fleet:
• Spirit of America (N10A), a blimp/non-rigid airship (model GZ-20A), based in Carson, California
• Spirit of Innovation (N2A), a blimp/non-rigid airship (model GZ-20A), based in Pompano Beach, Florida
• Wingfoot One (N1A), a semi-rigid airship (model LZ N07-101), based in Suffield Township, Ohio
They are filled with helium, and are used for advertising. You can’t help noticing a blimp when it cruises the sky.
