Craft - Lighter-than-air

The choice of gas determines the lift capacity and safety profile of the craft:

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 lighter-than-air craft

LTA vehicles are broadly categorized into unpowered and powered versions: The choice of gas determines the lift capacity

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

: Use a partial keel or frame to support the envelope and distribute weight. 2. Lifting Agents
