§ Mr. Critchleyasked the Secretary of State for Trade and Industry what arrangements have been made for representatives of bodies concerned with air- 96W craft noise to see the work being undertaken to quieten aircraft engines at the National Gas Turbine Establishment Pyestock.
§ Mr. OnslowOf 17 representatives of airport consultative committees and other bodies invited to visit the National Gas Turbine Establishment at Pyestock on 31st August, 11 were able to accept. They were shown the research being carried out into the fundamental causes of noise generation in jet aircraft engines and into the engineering problems involved in eliminating and reducing the level of such noise. They also saw the new noise testing installation now under construction which will make Pyestock one of the best equipped centres for this kind of work in the world. A further visit is planned for those who, because of other commitments, were unable to attend on 31st August.
