A blimp is a type of non-rigid airship that is kept afloat by internal pressure rather than by a rigid frame or chassis. The blimp’s distinctive shape is maintained by the pressure of the gas inside, which inflates the envelope or sac and gives it its characteristic rounded form.

Unlike a traditional airship, which relies on a rigid frame to provide structural support, the blimp is able to flex and bend in the air. This allows it to be more maneuverable and adaptable to changing weather conditions than a traditional airship.

Blimps have been used for a variety of purposes throughout history, including military surveillance, advertising, and scientific research. They are particularly useful for low-altitude flights, as they are able to operate at much lower speeds than other aircraft and can stay aloft for longer periods of time.

Today, blimps are still used for a wide variety of purposes, from providing aerial coverage of sporting events to conducting scientific research in remote or hard-to-reach areas. While they may not be as common as they once were, blimps remain an important part of aviation history and continue to play an important role in modern aviation.
