Falcons could inspire the next generation of aircraft technology as scientists at BAE Systems and City, University of London research the birds of prey.
The technologies contributing to air safety, aerodynamics and fuel efficiency could be applied within the next 20 years.
The scientists have developed several concepts following research into how the peregrine falcon 鈥� the world鈥檚 fastest bird 鈥� is able to stay in control and airborne at speeds of up to 200mph, even in high winds.
The technologies being developed include 鈥榮ensory feathers鈥� – 3D-printed polymer 鈥榟air鈥� filaments which would act like sensors on the body of an aircraft, providing an early warning system if it began to stall.
Similarly, more densely packed passive polymer filaments may also be capable of changing the airflow very close to the surface of the aircraft which could reduce 鈥榙rag鈥� on the aircraft wing-skin. Aerodynamic drag ultimately slows aircraft in flight.
A further technology has been inspired by the falcon鈥檚 ability to stabilise itself after swooping or landing by ruffling its feathers. Small flexible or hinged flaps on an aircraft could allow the wing to manoeuvre quickly and land more safely at lower speeds.
The added safety margin gained using this approach could allow future aircraft of a more compact design or to carry more fuel.
In addition, the research so far has shown that the flaps could potentially lower聽 aircraft noise pollution.
Professor Christoph Bruecker from City鈥檚 Aeronautical Engineering department, said: 鈥淭he peregrine falcon is the world鈥檚 fastest bird, able to dive for prey at incredibly steep angles and high velocities.
鈥淭he research work has been truly fascinating and I am sure it will deliver some real innovation and benefits for the aerospace sector.鈥�
Professor Clyde Warsop, a specialist in Aerodynamic Flow Control at BAE Systems鈥� military aircraft based at Filton in Bristol and Warton in Lancashire added: 鈥淲orking with Professor Christoph Bruecker and his team at City, we鈥檝e investigated how we could apply the unique abilities of the peregrine falcon to aircraft.
鈥淏io-inspiration is not a new concept; many technologies that we use every day are increasingly inspired by animals and nature.鈥�
