Thank you for your interest in this course. Due to current restrictions regarding in-person events this activity will be postponed whilst we look into the possibility of rescheduling this event or hosting online

OVERVIEW

Aircraft noise has been become a prominent source of media headlines, a subject for green lobbies, and a concern for operators and decision-makers, particularly at a time when further airport expansion is made difficult by land planning and various environmental restrictions. This course will address these wider problems, but it will focus specifically on the engineering aspects of generation, propagation and mitigation of aircraft noise. This course deals with commercial airplanes powered by gas-turbine engines. Unique features of this course include multi-disciplinary analysis of aircraft noise: aerodynamics, propulsion, acoustics, outdoor sound propagation, flight physics, numerical optimisation, system engineering, certification and regulations, and stochastic analysis.

PRACTICAL INFORMATION

The University offers state-of-the-art conference and computer facilities and is conveniently located in the city centre of Manchester, one of the major metropolitan areas in the United Kingdom. For hotel reservation and general information, please contact the MACE Operations team on MACEOps@manchester.ac.uk

TARGET AUDIENCE

This course is addressed to professionals, engineers, scientists, graduate students with interest in the effects of noise emissions from an engineering and technology point of view. Target businesses include commercial airlines, air traffic control, aviation organisations and regulators, aircraft and power plant manufacturers, aircraft designers, policy makers, aviation consultancy businesses, graduate students and academics.

CONTENTS

Session 1: Critical introduction, noise regulations, trends, data, airports, noise certificate, legal aspects

Session 2: Noise metrics: instantaneous, tonal/broadband, time averaged, integral, short- long term

Session 3: Aircraft noise sources

  • Engineering systems and network analysis
  • Airframe noise: sources, characterisation, modelling, prediction
  • Engine noise: as above, specifically: fan system noise, core noise, jet noise
  • Propeller and counter-rotating prop noise: : sources, modelling, prediction methods

Session 4: Aircraft noise propagation

  • Noise propagation models, focus on long-range issues
  • Effects of topography, including ground and background noise
  • Effects of atmospheric winds and humidity

Session 5: Noise measurements

  • Noise measurements at airfields
  • Automatic noise tracking at airfields
  • Noise measurements in laboratory conditions

Session 6: Noise reduction by trajectory optimisation

  • Elements of multi-objective optimisation
  • Trajectory constraints and typical operations (NADP, steep-descent, etc.)

Session 7: Noise footprints, effects of multiple aircraft movements

  • Noise mapping

CASE STUDIES: Commercial airplanes (turbofan and turboprops)

  • Departure aircraft noise
  • Arrival & landing aircraft noise
  • Calculation of noise footprints (single/multiple aircraft operations)
  • Noise sensitivity studies (effects of operation, gross weight, source components)

All computer exercises carried out with in-house code.

DELIVERABLES:

  • Course Notes, Teaching Material, Case Studies
  • A version of the Noise Simulation Software (FLIGHT)

(*course date may be subject to change)

Price: £850

Concessions: (£390 for registered post-graduate students and early-career engineers)
