In the fields of Lighter-than-air-craft a growing global interest and quite ambitious activity in developing large high-tech airships for specific promising applications (e.g. cargo lifting) and Zeppelin NT can be observed nowadays.
But what exactly is a lighter-than-air craft and how does it work? This paper gives an overview about all LTA-concepts and their pros and cons.

Chapter Summaries
- Introduction: This chapter provides an overview of lighter-than-air concepts, highlighting their historical significance, contemporary use, and the underlying principles of buoyancy. The author emphasizes the distinction between balloons and airships.
- Hot Air Balloons: This chapter focuses on hot air balloons, exploring their origins, basic components, operating principles, and current applications. It discusses their role in leisure, tourism, and sport, while acknowledging the limitations of hot air for large-scale airships due to its low lift and high heating costs.
- Lighter-than-air crafts: This chapter introduces the concept of airships as powered LTA crafts capable of controlled direction. It classifies airships into three main types: rigid, semi-rigid, and non-rigid (blimps). The chapter details the essential components of all airships, including their lifting gas systems, gondolas, and propulsion mechanisms.

What is a lighter-than-air (LTA) craft?
An LTA craft is a vehicle that stays airborne by using a gas that is less dense than the surrounding atmosphere, creating buoyancy.
What are the three main types of airships?
Airships are classified as rigid (with an internal frame), semi-rigid (with a partial keel), and non-rigid (blimps, which maintain shape through gas pressure).
How do hot air balloons differ from airships?
Balloons are generally unpowered and drift with the wind, while airships are powered and can be steered in a specific direction.
What gases are commonly used in LTA crafts?
Helium is the most common gas today due to its safety, while hydrogen was used historically for its superior lift but is highly flammable.
What are the advantages of modern airships?
They are highly fuel-efficient, can stay airborne for long periods, and are capable of lifting heavy cargo to remote areas without runways.
What is the "Zeppelin NT"?
The Zeppelin NT is a modern semi-rigid airship used for tourism and scientific research, representing a high-tech revival of the classic Zeppelin concept.
