: Rely entirely on internal gas pressure to maintain their shape.

The choice of gas determines the lift capacity and safety profile of the craft: lighter-than-air craft

: Use a partial keel or frame to support the envelope and distribute weight. 2. Lifting Agents : Rely entirely on internal gas pressure to

Lighter-than-air (LTA) craft, also known as , operate on the principle of buoyancy—displacing a volume of air with a gas that is less dense, thereby creating upward lift. Unlike airplanes, which rely on aerodynamic lift generated by movement through the air, LTA craft can remain aloft while stationary. 1. Types of LTA Craft also known as
