Dynamic Aircraft Wing Adjustment for Quieter and More Fuel-Efficient Landings

transportPrototypeTRL 3

Imagine if a plane's wings could adjust their shape smoothly like a sliding dimmer switch instead of clicking into a few fixed settings. This allows planes to descend at a steeper angle, staying higher for longer to keep noise away from houses on the ground. It prevents the plane from wasting fuel or struggling to slow down during the final approach to the runway.

The business problem

What needed solving

Aircraft using steep descent angles to reduce ground noise often struggle to slow down, forcing pilots to deploy flaps too early. This leads to higher fuel consumption and inefficient energy management during landing.

The solution

What was built

The project is building optimization algorithms and a conceptual stepless automatic high-lift system to dynamically adjust wing configurations.

Business applications

Who can put this to work

Aerospace Manufacturing
enterprise
Target: Airframe and Wing Manufacturer

If you are a wing manufacturer dealing with rigid high-lift settings that limit descent flexibility — this project developed a stepless automatic high-lift system that adapts to wind and aircraft mass. This allows for steeper glidepaths without increasing fuel consumption.

Aviation Electronics
enterprise
Target: Avionics Systems Provider

If you are an electronics provider dealing with the need for better pilot-ATC coordination during approach — this project developed optimization algorithms that help pilots follow speed assignments more accurately. This improves traffic flow within the Terminal Manoeuvring Area.

Airport Operations
enterprise
Target: Airport Authority

If you are an airport operator dealing with noise complaints from residents near the runway — this project developed a method to increase glideslope angles safely. This reduces noise perception on the ground while maintaining fuel efficiency for arriving flights.
