§ 41. Mr. Gresham Cookeasked the Minister of Supply whether he will take steps to assist British aircraft manufacturers to acquire the silencer for jet aircraft produced by the Boeing Airplane Company; and if he will make a statement.
§ The Parliamentary Secretary to the Ministry of Supply (Mr. F. J. Erroll)So far as I am aware, the Boeing silencer follows the design of a silencer developed by Rolls-Royce under contract with the Ministry of Supply. Flight tests of the Rolls-Royce silencer will start shortly; meanwhile, details of the Rolls-Royce design have been made available to other firms in the British aircraft industry.
§ Mr. Gresham CookeWhile I thank my hon. Friend for his Answer, may I ask him to encourage manufacturers of jet aircraft to fit the Rolls-Royce silencer, as that will give a great deal of satisfaction to those who live around London Airport?
§ Mr. ErrollIt is a complicated design matter, but all firms are fully aware of the importance of trying to reduce the noise of aircraft by every means at their disposal.
