Wing vibrations to power future aircraft?

The work is part of a wider £1million project led by BAE Systems called En-come, which aims to develop aircraft that can stay in the air for longer periods of time without having to re-fuel. Principal investigator Professor Jianqiao Ye, of Lancaster University's Engineering Department, said: "Our role is to look at saving the power used to support the monitoring system. There needs to be frequent communication between the aircraft and earth and power is needed to send huge constant quantities of data as well as receiving instructions from a communications centre." The Lancaster research will look at how mechanical energy generated by the vibration of the aircraft's wings can be transferred, stored and used to support the communications system. Sensors constructed from special spatial material are adhered to the surface of the aircraft wing panels. Vibration from the wings is then transferred to and collected by the sensor to generate electricity and, therefore, maximising the energy generated by the craft. The Lancaster researchers will examine the actual structure of the aircraft and estimate the amount of energy that can be 'harvested' in this manner by looking at the location, geometry of the sensor and the distribution of the energy. The consortium will also look to see how the process could be improved and built on from, for example, a design perspective and using wireless connections to reduce weight. Professor Ye added: "This is a very exciting project involving fundamental research and industrial impact national and internationally. "There are many potential applications of this technology – not just for the aerospace industry but for others including offshore activity – and the potential for a commercial development. It is the integration of different aspects of sensors, structure design, signals and software support – a full package of technology. We are very excited."
