Researchers from the University of Lincoln, UK, have completed a three year investigation into stratospheric passenger airships as part of a multi-national engineering project designed to provide a future sustainable air transport network.

A group of academics from the University's School of Engineering have been members of a pan European research team that believes airships may be the 'green' answer to the future growth of aviation.

The Multibody Advanced Airship for Transport (MAAT) project aims to position airships as the solution for future air transportation that is safe, efficient, cheap and environmentally friendly.

As engineering projects go, a plan to reintroduce airships as a cheap and energy-efficient means for mass transportation of people and goods might be the definition of blue sky thinking but there is a need for a mid-range transport system that efficiently trades speed for fuel consumption.

It is therefore rather fitting that approximately 85 years after Barnes Wallis of the Airship Guarantee Company, a subsidiary of Vickers-Armstrongs, based in Howden designed and successfully tested the R100 the first of the Imperial Airships that we should be now be reconsidering airships as a green alternative for future passenger and freight use.

The MAAT project, made up of eight nations and led by the Universita di Modena e Reggio Emilia in Italy, envisages the design of a cruiser which can travel across the globe on a set route. Smaller feeder ships carrying people and goods would then be able to dock onto the cruiser while it is still moving.

The primary energy source for the MAAT is through harvesting sunlight from photovoltaic arrays mounted on the upper airship surface to provide sufficient electric power during the day to operate the airship's systems, and provide life support, propulsion and control, while also producing sufficient excess energy that can be stored to facilitate continuous MAAT operation at night.

The University of Lincoln team's research has focused on how to make the most efficient use of energy generated by the photovoltaic cells on the airships and its subsequent use in the electrical power systems, energy storage and the propulsive power requirements. It is hoped that with the introduction of innovative propulsion systems that the limitations of traditional propellers at high altitudes will be overcome resulting in an efficient propulsive system.

A paper detailing the Lincoln group's initial findings was previously published in the Journal of Aerospace Engineering.

It described the energy systems and presented various design options that could be adopted for airships, particularly highlighting the issues of day/night operation and its impact on the on-board energy storage systems.

The project has moved on significantly since then with a revised approach to the energy harvesting, distribution and storage utilising a modular approach to simplify future scaling and address system integrity under failure conditions.

Tim Smith, Senior Research Fellow at the Lincoln School of Engineering, said: "While the concept of a feeder-cruiser arrangement for airships is not entirely novel, the projected scale and operating altitude of the proposed MAAT is unprecedented. Operation is based on a large-scale 'cruiser' ship at high altitudes of around 15km, at airspeeds of up to 200km/h for extended periods, on pan European routes along which there exist exchange points where VTOL 'feeder' airships operate from ground stations rendezvousing and docking with the cruiser in order to exchange passengers and freight. The underlying concept is to have multiple feeders docking with the cruiser."

It is forecast that by 2020 the number of aircraft passengers will reach 400 million. The movement of freight by air is expected to increase by more than 340 per cent over the next 20 years. During the same period congestion at many of the UK's airports will squeeze out cargo operations because of economic and environmental reasons. Consequently if the market demand for air freight is to be met, either there will have to be significant investment in new airport infrastructure or alternative transport forms need to be considered.

MAAT would present lower costs of transportation than any other current transport system, as it does not require fuelling and its vertical take-offs would reduce delivery times and free-up runway space across the globe. Also, silent landing and take-off operations would reduce the environmental impact of air travel allowing 24-hour operation within busy cities.

While MAAT (and other airship concepts) are not intended to replace conventional aircraft or other forms of transport, they are expected to provide a much needed alternative that do not require the large infrastructure investments typical of new airports, railways and roads.

Tim Smith added: "The design of an all-electric airship is demanding, as by its very nature it is unforgiving as increasing efficiency invariably increases weight which impacts the size, which impacts drag and so on. The greatest challenge has been managing the electrical systems efficiency and weight, thus preventing the spiral -- this will be a continuing challenge."
