Seymourpowell introduces the Aircruise - a clipper in the clouds

jueves, 18 de febrero de 2010

 
Leading design and innovation company Seymourpowell is today unveiling full details of its visionary transportation concept, Aircruise - a giant, vertical airship powered by natural energy and designed to carry travellers in style and luxury.

Originally a self-generated project, Seymourpowell's Aircruise is the concept design for a hotel in the sky, with low passenger numbers and huge internal spaces offering room for living, dining and relaxing, as well as scope for dramatic and inspirational public spaces. The initial design proposes a bar/lounge zone, four duplex apartments, a penthouse and five smaller apartments.

The concept subsequently captured the imagination of Korean giant Samsung Construction and Trading (C&T). Driven by its interest in new materials for building, Samsung C&T appointed Seymourpowell to refine the idea and produce a detailed computer animation of the proposed experience to illustrate this visionary approach to the future. The video can be viewed here:

Seymourpowell's Aircruise concept presents an alternative take on the future, suggesting 'slow is the new fast'. Nick Talbot, design director at Seymourpowell explains, "The Aircruise concept questions whether the future of luxury travel should be based around space-constrained, resource hungry, and all too often stressful airline travel. A more serene transport experience will appeal to people looking for a more reflective journey, where the experience of travel itself is more important than getting from A to B quickly."

On Aircruise, it is the very abundance of time and space that defines the luxury experience. In a world where speed is an almost universal obsession, the idea of making a leisurely journey in comfort is a welcome contrast. Talbot explains, "The physics of the airship requires a gigantic volume of lifting gas, yet simultaneously demands a relatively limited amount of weight. This allows for a potentially large amount of space with relatively few people onboard - a luxury for any traveller."

Talbot added, "It's a world cruise not limited to the ocean, offering instead the dream-like quality and absolute freedom of flight. Passengers can choose to dine thousands of feet above a city, or take in the view whilst moving through the air over the ocean or a national landmark."

Lifted by hydrogen and powered by solar energy, the Aircruise concept also has obvious environmental benefits. Seung Min Kim, design director at Samsung C&T commented, "This was a dream concept project for us, helping to realise a future of sustainable buildings combined with innovative and luxury lifestyle. In an age when environmental impact is a key consideration for architecture, we are keen to extend this vision of the future by searching for solutions that can be realised by 2015 - the year that many futurologists foresee as the turning point for the future."

Although only a conceptual proposal, the transportation design team at Seymourpowell developed a detailed and achievable technical specification for the craft. See below for further technical details.

Proposed conceptual specifications for Aircruise as follows:

From the docking rig at the base to the tip, the ship is 265 metres tall. Hydrogen, the lightest gas, is used as the lifting gas, and is capable of lifting around 1.2Kg per cubic metre of volume. Large PEM hydrogen fuel cells will provide on board power and some drinking water.

The volume of the main envelope in the ship is calculated at 330,000 cubic metres, which equals 396,000 Kg of available lift at sea level (1,000Kg = 1 Tonne (t)).

Estimated weights:

Primary structure, envelope and systems 270t (reference - around the same weight as an airbus A380 super jumbo, empty weight)
Consumables, water, ballast etc. 20t  
People (estimate max 100 people on board) 15t  
Control deck and staff (20 staff) 6t  
Bar/Lounge/communal zone fit out 15t  
4 Duplex apartments at 5t each 20t  
Penthouse apartment 12t  
5 smaller apartments at 4t each 20t  
Total load factor 378t  

Available lift excess is therefore 18-20t or 20,000kg of lift.

Part of the renewed interest in airships derives from advances in materials, structures, stabilisation and clean propulsion technologies. Utilising composite frames and fabrications, lightweight semi flexible structures can be built at large scales. Although large, this is nevertheless a semi rigid ship, the primary tensioned structure consisting of 8 vertical composite lattices supporting four main flexible envelopes, which contain 330,000 cubic metres of hydrogen gas. Lower decks are 'hung' off these primary supports.

Each of the 4 external envelopes contains modular self-sealing lifting bags, minimising the incidence of bag rupture and ensuring safe flight even with a major external skin rupture.

Automatic stability thrusters and altitude control using automatic adjustment of the gas density ensures a smooth ride compared to previous airships. Although still susceptible to storms and very poor weather, advanced weather radar and weather prediction systems allow the ship to route around major problems.

Despite the perceived risks, hydrogen is used for its inherent lifting efficiency and as a power source. Flexible photovoltaic (solar panel) cells cover the upper part of the envelope, augmenting the primary power generation, in this case from fuel cells. Large surface area PEM fuel cells generate the primary power for on board systems and turn low speed compressors located in the mid section of the ship. This compressed gas is ducted to provide directional thrust and auto stabilisation. Compressed hydrogen stored in parts of the main structure provides fuel for longer ranges and by venting to the envelope or re-compressing these volumes, altitude stability is achieved.

By combining the lifting gas and the fuel for thrust the overall weight of the ship can be minimised, whilst ensuring a silent, pollution free passage. Water vapour is harnessed to augment on board potable water.

The service ceiling is limited to 12,000 feet, given the attenuation of the atmosphere (the hotel is not pressurised) and the limits of gas expansion within the envelope. If however, there are specific locations of interest en route, the ship can drop down to within a few hundred feet of the ground.

Cruising speed without tail or headwind is 100 - 150 Km/hr. This equates to journey times that are appropriate to the cruise experience: London to New York in 37 hours; Los Angeles to Shanghai in 90 hours.

Six-flight crew will include two flight engineers, and will fly the ship in shifts, given the likely cruise durations. 14 support staff will run the hotel experience for the guest passengers.

Aircruise: nuevo concepto que revolucionaría el transporte, un crucero – dirigible

 
Con una peculiar forma de cometa, este proyecto a futuro se desplazaría en total silencio y sin contaminar: esta singular nave, que reuniría la funcionalidad de un crucero con la de un hotel flotante, combinaría la energía solar con hidrógeno para alcanzar una velocidad de crucero de alrededor de 180 kilómetros por hora sin emitir prácticamente tóxicos a la atmósfera.
 
 
El zepelín se elevará hasta 3 kilómetros y medio de altitud gracias a los 330.000 metros cúbicos de hidrógeno que lleva en su interior. A bordo de este crucero, con capacidad para 100 pasajeros, podremos ir de Londres a Nueva York en 37 horas, o de los Ángeles a Shanghái en 90 horas. Y en su interior, una piscina con fondo transparente nos permitirá nadar "sobre las nubes", literalmente
 
 
Flying to New York? Then why not go by luxury airship (but it will take you 37 hours)
Aircruise was created as the antithesis of a hurried, crowded passenger jet. London-based design and innovation company Seymourpowell wanted to rethink transport - on the premise 'slow is the new fast'. It could ferry 100 people from London to New York in a leisurely 37 hours as opposed to the seven it takes now by airplane
