Airship — what is it, how does it work, and why is it needed
In the age of supersonic aircraft and spacecraft, airships may seem like a relic of the past. Yet these giant “flying ships” have not only survived — they are making a comeback. In this article, we explain in plain language what an airship is, how it is built, what it’s for, and why modern engineers are paying renewed attention to it.
What is an airship in simple terms
Definition
An airship is a controllable, lighter‑than‑air aircraft that can move in any direction thanks to its own powerplant (typically propellers) and control system. Unlike balloons, it does not simply drift with the wind; it flies purposefully wherever the pilot needs it to go.
Why it flies but isn’t an airplane
An airplane stays aloft thanks to lift generated by its wings as it moves forward. An airship does not need speed to fly — it rises because it is filled with a gas lighter than air (for example, helium). This makes it a fundamentally different type of aircraft.
How an airship differs from an aerostat and a balloon
A balloon is an uncontrolled craft that depends on the wind.
An aerostat is usually used for observation, can be tethered, and also has no engine of its own.
An airship has engines, control surfaces, and a control system, allowing it to fly autonomously and purposefully.
The history of airships: from first flights to today
The first airships and their inventors
The history of airships began in the 19th century. The first controllable airship was built by French engineer Henri Giffard in 1852. His craft, powered by a steam engine and a propeller, completed the world’s first flight over a distance of about 27 km. Later, in the early 20th century, Count Ferdinand von Zeppelin created rigid airships that became symbols of the era — the creator of the zeppelin laid the foundations of an entire industry.
The peak of popularity and the Hindenburg disaster
In the 1920s–1930s, airships were used for passenger travel between continents. The most famous of them was the Hindenburg — a giant German airship that exploded while landing in the United States in 1937. The Hindenburg disaster proved a turning point: the world lost confidence in such craft, especially because of the use of hydrogen, which is highly flammable.
Why airships disappeared — and why they are returning
With the development of aviation, airplanes turned out to be faster, more reliable, and cheaper to operate. Why did airships disappear? The main reasons were accidents, high costs, vulnerability to weather, and the emergence of more efficient technologies.
Today, however, airships continue to evolve and are experiencing a new chapter: modern materials, safe gases (helium), environmental benefits, and unique capabilities are making them sought after in new fields.
How an airship is built and how it flies
Design: envelope, gas, propellers
Core components:
Envelope — an airtight “skin” that contains the lifting gas.
Gas — usually helium, which is safe and lighter than air.
Gondola — a cabin for the crew and passengers.
Engines and propellers — provide propulsion and maneuverability.
Principle of lift and control
An airship rises due to the density difference between the gas inside and the surrounding air. Control is provided by elevators and rudders, as well as by varying engine thrust. This makes it a propeller‑driven aircraft capable of free flight.
Key point: designs and shapes of airships can vary, but all are based on the “lighter‑than‑air” principle.
Types of airships
Rigid — have an internal framework (as in Zeppelins). The envelope does not carry load.
Semi‑rigid — supported partly by a framework and partly by internal gas pressure.
Non‑rigid — the shape is maintained solely by the overpressure of the gas inside.
Modern models are most often non‑rigid or semi‑rigid, as they are simpler to manufacture and service.
Airship performance: speed, altitude, capabilities
How fast an airship flies
The average cruising speed of an airship is 70–130 km/h. That is slower than an airplane, but sufficient for many tasks — especially when efficiency and payload matter more than speed.
How high airships fly
Airships typically fly at 300–3,000 meters. The maximum flight altitude depends on the model but rarely exceeds 4 km — above that, the thin air makes control difficult.
What airships are for — then and now
Historical uses
Military purposes: reconnaissance, bombing.
Passenger transport: transatlantic flights.
Advertising: bright envelopes served as flying billboards.
Modern uses
Logistics: transporting heavy and oversized cargo to hard‑to‑reach regions.
Environmental benefits: low noise and zero CO₂ emissions.
Tourism: exclusive aerial excursions.
Observation: monitoring forests, seas, and borders.
What is an airship good for today? It is an ideal compromise between a helicopter and a truck: quiet, capacious, and environmentally friendly.
Modern airships: who is building them and why
In the 21st century, airships are experiencing a rebirth. Among real‑world projects:
Airlander 10 (United Kingdom) — a hybrid of an airship and an airplane capable of transporting 10 tons of cargo.
Lockheed Martin LMH‑1 — developed for cargo delivery in the Arctic.
Russian and Chinese companies are also developing new models for monitoring, tourism, and logistics.
Modern airships are used in agriculture, geology, rescue operations, and even as platforms for providing internet access in remote areas.
Advantages and disadvantages of airships
Pros
Environmental benefits: do not burn large volumes of fuel.
Payload: can lift tens of tons.
Safety: slow descent in emergencies, no risk of explosion (when using helium).
Cost efficiency: low energy consumption.
Cons
Lower speed compared to airplanes.
Weather dependence: strong winds or storms can halt a flight.
Limited infrastructure: few dedicated airship bases.
Even so, what an airship can do makes it indispensable for niche yet important missions.
Interesting facts
The word “airship” comes from the French dirigeable — “steerable.”
Yes, airships were very real — and not just in the movies. In the 1930s they regularly crossed the Atlantic.
Do airships fly today? Yes. Dozens of commercial and research models operate worldwide.
The future of airships and their role in the world
The world is once again turning to airships. As demands for sustainability, accessibility, and safety increase, the airship of the future could become a key element of sustainable logistics and monitoring.
Is a “renaissance” possible? Absolutely — especially under climate change and the need to deliver cargo where there are no roads.
