This National Technical Committee is managed by the Aerospace and Defence Knowledge Transfer Network.

The objectives of the UK Environmental Technology National Technical Committee ¨C Noise (ETNTC)?network are similar to those of the UK X-Noise Network in Aeroacoustics, therefore for most of the practical aspects (communications, strategies, roadmaps, etc.) they are treated as a single network.

The main objectives of the ETNTC are:

• Ensure stakeholders have a shared understanding of applied research needs and priorities, in order to maintain and enhance UK competitiveness.
• Maintain Technology Route Map in key topics that reflect both opportunities and requirements.
• Manage a portfolio of research to deliver the Technology Route Map.
• Disseminate information across industry, academia and the supply chain.

The ETNTC will cover research of advanced concepts in the areas of:

• Technologies and design approaches to meet the ACARE 2020 goals for civil aircraft (baseline ¨C year 2000 operations):
  
  1. 50% reduction in CO2 emissions per passenger km.
  2. Half current perceived average noise levels.
  3. 80% reduction in NOx.
• Technologies for minimising the effects of smoke and noise emissions from military aircraft including small-scale particulate emissions.
• Step-change developments in both powerplant (combustor temperature control, component / system efficiency) and airframe design (drag reduction, noise attenuation, turbulence control).
• Improving local air quality and noise near airports, for passengers and cabin crew within the aircraft and for support staff on the ground.
• Reducing dependence on scarce minerals and compounds and increasing sustainability.

The programme will engage industry, supply chain, universities and funding partners. The nominated industry lead company is Rolls-Royce plc. The main contact for the ETNTC ¨C Noise is Dr Andrew Kempton [Rolls-Royce, andrew.j.kempton@rolls-royce.com ].

Note that the ETNTC was formerly called the Environmental Technology Aerospace Innovation Network.
