"Airlander is a “back to the future technology” capable of disruptively altering logistics and mobility. If COVID-19 has taught humanity anything as we enjoyed clean air first time in a century, it is simply “a smarter, cleaner, safer way of mobility is possible”. Sectors across the globe will be embracing the carbon free Airlander for a variety of transportation needs. Aerospace tends to focus on higher, faster, further - but in 2020 the words efficiency, economy and clean are more relevant. "

"During thirty-six years in Military Intelligence, I saw innumerable initiatives promising to revolutionize the quality of intelligence afforded Army Soldiers and Joint Forces. Almost without exception they delivered, at best, marginal gains at ever-increasing cost. Airlander, backed by an innovative and customer-outcome focused team is a notable exception – world-class capabilities are now available at a fraction of the cost of today’s ISR platforms, addressing essential threats and needs."

Frequently Asked Questions

What is a hybrid aircraft?

A hybrid aircraft derives its lift from a combination of aerodynamic lift (like an aeroplane), lifting gases (like an airship) and vectored thrust (similar to a helicopter). Airlander generates up to 40% of its lift from aerodynamics by the passage of air over the hull and the remainder from buoyant lift from the helium. At lower speed and closer to the ground, vectoring engine power is used to provide additional lift and manoeuvrability for take-off, landing and ground handling.

What makes Airlander green?

One of the biggest challenges for aviation is finding ways to replace energy-dense kerosene (typical aircraft fuel) with environmentally friendly alternatives. Airlander requires significantly less thrust to fly than conventional aircraft, thanks to its helium-filled hull. That makes it possible for us to adopt technologies like hydrogen fuel cells while still delivering large payloads. Even before we adopt electric propulsion, we burn 75% less fuel than other aircraft in comparable passenger-carrying roles - and deliver better than this in many other roles. With our hybrid-electric configuration we achieve 90% reduction in passenger transport, and we have a pathway to all-electric, zero-emission aviation.

What happens in bad weather?

Like any other commercial aircraft, Airlander will be type certified and capable of flying in a wide range of weather conditions. The aircraft can safely take off and land in up to 30 knots of wind. Unlike other large aircraft, Airlander is not cross-wind restricted, as it can simply turn into the wind and take off in any direction. The aircraft will also be capable of withstanding lightning strikes and icing conditions. This is a requirement for all type certified commercial aircraft.

How is Airlander different to the numerous eVTOL companies which are out there?

The biggest difference between Airlander and eVTOLs is scale. Most eVTOLs are for 2-6 passengers, while Airlander will be able to fly with 90 passengers. We have also flown Airlander 10 as a full-scale prototype and are ready to enter production. We have strong, established relationships with regulators, a plan for Type Certification, and both Design and Production Organisation Approvals. These are critical steps on the journey to bringing a new aircraft type to market and will see Airlander 10 available for operation within just a few years. There are some eVTOL aircraft that are in early flight testing now, but most are earlier in their development. Most eVTOLs are intended for use in cities, as “flying taxi” type concepts. Airlander can serve as the connection between two cities. The hybrid-electric Airlander 10 will produce a fraction of the emissions of a comparable fixed-wing airplane. We often think of Airlander as a "fast ferry" in the way that it will provide connections city to city.

How does the aircraft operate in remote locations?

In many operational scenarios there is no need to moor Airlander at a remote location. The aircraft can land, unload and load, and then take off again. However, there may be occasions when mooring at a remote site is needed or desirable. Airlander has an Expeditionary Mooring Mast (EMM) system, which weighs approximately 1000kg, or less than 10% of Airlander 10’s payload capacity. It can be stowed aboard the aircraft with minimal impact to the accommodation or freight area. The EMM is designed to operate in up to 70 knots of wind, so it is as capable from a loading and weather standpoint as our standard Mobile Mooring Mast (MMM). It could be carried on the first flight into a location and left erected for subsequent flights, if that location were to be in frequent use. The MMM is a tracked all-terrain vehicle and is not currently designed to be deployed using Airlander.

Do you plan to make larger variants of Airlander?

Our future plans include larger Airlanders, including Airlander 50 and Airlander 200, with the number approximating to tonnes of lift. These larger aircraft benefit from all of the same efficiency advantages as Airlander 10, but can carry significantly larger payloads. Airlander 50 is in the early stages of design, but we anticipate that we could deliver an all-electric Airlander 50 in the early 2030s. This aircraft, with approximately 50 tonnes of point-to-point lift capability and a range of 4,000 nautical miles, will be the future of heavy lift freight transport. The aircraft’s ability to operate without a conventional runway avoids intermodal hubs and delays, as well as opening up inaccessible or hard to reach locations.

What is the fastest speed Airlander can travel and what is the longest duration it can stay in the air?

Airlander 10 has a top speed of 130kph and can stay airborne for up to 5 days. For our customers, speed is not Airlander’s most important feature. In communications & surveillance applications, the key feature is the ability to stay in the air for long periods of time. This provides continuity of coverage that no other aircraft can currently provide. In luxury ecotravel, travelling slowly allows passengers to enjoy the landscape beneath the aircraft. It also makes the flight much more comfortable. In mobility, Airlander can fly point-to-point rather than relying on traditional transport infrastructure. This makes total journey time for shorter routes competitive against other options. Importantly, Airlander will do these journeys with very low carbon footprint. In logistics, Airlander is more efficient than air freight and faster than sea freight. Airlander’s ability to operate without traditional fixed infrastructure also provides an advantage, making remote operations possible.

How can Airlander avoid detection during its surveillance roles and how secure is it in respect to attack from the ground?

Aircraft using lighter-than-air technology like Airlander have been in use in defence applications for decades. Airlander’s construction results in a relatively low radar return and a low heat signature. The aircraft is very durable and can in fact fly on just one of its four engines. Helium leaks very slowly from the hull, so the aircraft can stay airborne even after being punctured by a projectile. More information can be found on our website. The aircraft can fly at up to 20,000 feet and typically operates at altitudes above the range of small arms fire and most man-portable air defence systems. In practice, missions will be specifically designed to make use of the aircraft’s strengths and protect it from potential enemy engagement, which is true of all aircraft. Airlander’s ability to carry and maintain large sensor payloads for long periods of time is a significant advantage. During 2018, Airlander was modelled in a NATO trial, the results of which showed just how transformative it can be.
