Harnessing Landing Power to Cut Noise and Emissions

Funded by the Engineering and Physical Sciences Research Council (EPSRC), a team of engineers from the University of Lincoln have confirmed that future aircraft could harness and store energy produced by landing gear, which could then be used to taxi the aircraft – a necessary, but very fuel-wasting, function of air travel. In addition to the fuel-inefficiency of taxiing aircraft, leader of the research, Professor Paul Stewart, noted that emissions and noise pollution caused by jet engines is a huge problem with airports worldwide. Little wonder then that the Advisory Council for Aeronautics Research in Europe (ACARE) has made engine-less taxiing one of its key objectives for the aviation industry in Europe beyond 2020.

Stewart added that if aircraft produced in the next fifteen to twenty years could incorporate the technology currently being investigated it would be enormously beneficial, particularly for people living in the vicinity of airports. The University of Lincoln’s research is assessing a number of methods of capturing the power generated by a landing airplane. In an interview, Professor Stewart, explained than when an Airbus 320 lands, the combination of its speed and weight produces around three megawatts peak available power. The team of researchers has explored different ways of harnessing that available power, including the interaction between magnets attached to the airplane and copper coils implanted in the runway. To date, many of the ideas have not proven to be feasible, either from a technical point of view or financially, or both. Nonetheless, the study has shown that it’s possible to capture energy in this manner, especially in light of advances being made in developing more-electric, or even all-electric, airplanes.

This collaborative effort between the University of Lincoln and the University of Loughborough is being carried out under the direction of the Airport Energy Technologies Network (AETN) which was established in 2008 by the UK-based Engineering and Physical Sciences Research Council (EPSRC) to facilitate low-carbon research in the field of aviation.
