The CHAIRMAN, in introducing the lecturer, said that they were fortunate in having an extremely topical lecture The subject of gas turbines and their application to helicopters was currently taking a great deal of attention from designers and industry, and the Association were happy to have it in the programme so early in the session

Mr BROWN had been educated at the City Boys Secondary Grammar School, Leicester, and was a State Scholar and a College Exhibitioner at Jesus College, Cambridge He had taken an Honours degree in the Mechamcal Sciences Tripos, and in 1944 joined Power Jets (Research and Development) Ltd, remaining when it became the National Gas Turbine Estabhshment He had been engaged as a research and development engineer on combustion processes and was now employed as a Senior Scientific Officer at the N G T E, being engaged on the examination of gas turbine projects and their thermodynamic performance

Introducing the lecturer, the Chairman said that like other learned societies they naturally had many papers on learned subjects, on the theory of this or that and the future of this or that It was a good thing from time to time for them all to realise that they were all engaged in building or using an actual vehicle which brought many problems with it It was only right and proper therefore, that from time to time they should come down to earth and face those problems

Mr BOULGER, of the Westland Aircraft Company, would speak on the problems associated with helicopter production He had been apprenticed at the R A E, had gone to the drawing office at Westlands, and had thence graduated to the design office For a time he had been with Messrs Normalair, an associated company, and then had returned to the Westland side of the family, where he had become Chief Planning Engineer It was from his work as Chief Planning Engineer that his intimate knowledge of the production problems arose He was now Contracts Manager of the Company
