The end of runways? Watch the incredible 'perching plane' that can land like a bird

  • Algorithm taught drone how to perform perched landings like birds
  • Researchers used a fixed wing drone because it can reshape while flying
  • Part of the wing tilts up to create more drag and the other keeps control of flight 

Drone makers have pulled inspiration from nature for their latest design – a drone that makes perched landings like a bird.

Researchers combined a morphing wing drone and machine learning algorithms to create a system that lets the machine perform perched landings on the ground.

The fixed wing aircraft also has the ability to land in small or confined places, which could be used to deliver aid in humanitarian disasters.

Researchers from the University of Bristol and BMT Defence Services set out to transform traditional fixed wing unmanned aerial vehicle (UAV) by adding morphing wing structures inspired by those found in birds.

The team chose a morphing wing drone, as it can reshape itself in mid flight.

This is the opposite of current UAVs, as these have fixed and rigid wings, which reduces the flexibility in how they can fly.

The wings let the drone swoop in for a perched landing - it lifts its wing just like a bird swooping in to land on the ground.

To control these complex wing structures, BMT utilized machine learning algorithms to learn a flight controller using inspiration from nature.

'Innovation is at the heart of everything we do at BMT and R&D projects provide us with the opportunity to work with our partners to develop cutting edge capabilities that have the potential to revolutionize the way we gather information,' said Simon Luck, Head of Information Services and Information Assurance at BMT Defence Services.

The drone has been tested in the field to demonstrate the team's new approach and researcher have been working on developing a system that can perform a repeatable ground landing.

'The application of these new machine learning methods to nonlinear flight dynamics and control will allow us to create highly maneuverable and agile unmanned vehicles,' said Dr Tom Richardson, Senior Lecturer in Flight Mechanics in the Department of Aerospace Engineering at the University of Bristol.

'I am really excited about the potential safety and operational performance benefits that these new methods offer.'

The 18-month research project was delivered as part of the Defence Science and Technology Laboratory's (Dstl) Autonomous Systems Underpinning Research (ASUR) program.

Last month, researchers from the Laboratory of Intelligent Systems was also inspired while watching birds in flight and created a drone that can spread or close its wings while flying, making it easier to manoeuvre and more resistant in high winds.

Because of its ability to adapt to its surroundings, researchers believe the feathered drone will prove successful in city landscapes where winds change rapidly.

We were inspired by birds: they can radically transform the size and shape of their wings because they have an articulated skeleton that is controlled by muscles and covered in feathers that overlap when the wings are folded,' explained Matteo di Luca.

'The drone also has feathers that it can fold and overlap like a fan.'

This inspiration gave them the idea to build an energy-efficient winged drone capable of changing its wingspan, flying at high speed and moving through tight spaces – an aerial vehicle that would fare well in urban environments.
