UK Engineers open flight path to quieter aircraft

21.05.2004


A new international project to reduce aircraft noise is building on pioneering research by UK engineers.



The Cambridge-MIT Institute’s Silent Aircraft Initiative (SAI) aims to design an aircraft that will make much less noise than conventional aeroplanes. To help meet its objectives, the project will use noise-modelling techniques devised by engineers at Cambridge University with funding from the Engineering and Physical Sciences Research Council (EPSRC). As well as Cambridge University, participants in the SAI include the Massachusetts Institute of Technology (MIT) and a number of other organisations.

Noise is a major aviation issue that will become even more pressing in future, with a 300% increase in air traffic forecast by 2020. This could have a major impact on the quality of life of people living close to airports. The SAI represents a response to the problem. It will take an integrated approach to aircraft design and operations, and investigate radically different aircraft configurations that could lead to dramatic reductions in noise.


The SAI will build on results from two EPSRC-funded projects. The first has led to the development of computationally efficient calculations of the noise made by helicopter blades moving at high subsonic speeds. It involved developing innovative but simple computer-based models that can provide a better understanding of how noise is produced during flight.

The second project is looking at jet noise. It aims to develop a prediction capability for jet noise which can be used, for instance, to assess how incorporating serrations or other modifications into jet engines can reduce jet noise at take-off. Achieving this will involve developing a computer model capable of predicting jet noise, improving understanding of noise source mechanisms, and identifying potential ways of modifying these mechanisms.

The Cambridge team involved in these two projects are now harnessing their expertise in a different way. Professor Ann Dowling of Cambridge University, who is leading the SAI, says: “The Initiative is not just about understanding and modelling aircraft noise. It aims to have an impact on the aerospace industry, and people living near airports, by developing designs and operational procedures for a radically different type of aircraft – an aircraft whose noise is almost imperceptible to the surrounding community.”

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
