5 Griffith, Alan Arnold
[br]b. 13 June 1893 London, Englandd. 13 October 1963 Farnborough, England[br]English research engineer responsible for many original ideas, including jet-lift aircraft.[br]Griffith was very much a "boffin", for he was a quiet, thoughtful man who shunned public appearances, yet he produced many revolutionary ideas. During the First World War he worked at the Royal Aircraft Factory, Farnborough, where he carried out research into structural analysis. Because of his use of soap films in solving torsion problems, he was nicknamed "Soap-bubble".During the 1920s Griffith carried out research into gas-turbine design at the Royal Aircraft Establishment (RAE; as the Royal Aircraft Factory had become). In 1929 he made proposals for a gas turbine driving a propeller (a turboprop), but the idea was shelved. In the 1930s he was head of the Engine Department of the RAE and developed multi-stage axial compressors, which were later used in jet engines. This work attracted the attention of E.W. (later Lord) Hives of Rolls-Royce who persuaded Griffith to join Rolls-Royce in 1939. His first major project was a "contra-flow" jet engine, which was a good idea but a practical failure. However, Griffith's axial-flow compressor experience played an important part in the success of Rolls-Royce jet engines from the Avon onwards. He also proposed the bypass principle used for the Conway.Griffith experimented with suction to control the boundary layer on wings, but his main interest in the 1950s centred on vertical-take-off and -landing aircraft. He developed the remarkable "flying bedstead", which consisted of a framework (the bedstead) in which two jet engines were mounted with their jets pointing downwards, thus lifting the machine vertically. It first flew in 1954 and provided much valuable data. The Short SC1 aircraft followed, with four small jets providing lift for vertical take-off and one conventional jet to provide forward propulsion. This flew successfully in the late 1950s and early 1960s. Griffith proposed an airliner with lifting engines, but the weight of the lifting engines when not in use would have been a serious handicap. He retired in 1960.[br]Principal Honours and DistinctionsCBE 1948. FRS 1941. Royal Aeronautical Society Silver Medal 1955; Blériot Medal 1962.BibliographyGriffith produced many technical papers in his early days; for example: 1926, Aerodynamic Theory of Turbine Design, Farnborough.Further ReadingD.Eyre, 1966, "Dr A.A.Griffith, CBE, FRS", Journal of the Royal Aeronautical Society (June) (a detailed obituary).F.W.Armstrong, 1976, "The aero engine and its progress: fifty years after Griffith", Aeronautical Journal (December).O.Stewart, 1966, Aviation: The Creative Ideas, London (provides brief descriptions of Griffith's many projects).JDS -
6 Gurney, Sir Goldsworthy
SUBJECT AREA: Automotive engineering, Land transport, Mining and extraction technology, Steam and internal combustion engines[br]b. 14 February 1793 Treator, near Padstow, Cornwall, Englandd. 28 February 1875 Reeds, near Bude, Cornwall, England[br]English pioneer of steam road transport.[br]Educated at Truro Grammar School, he then studied under Dr Avery at Wadebridge to become a doctor of medicine. He settled as a surgeon in Wadebridge, spending his leisure time in building an organ and in the study of chemistry and mechanical science. He married Elizabeth Symons in 1814, and in 1820 moved with his wife to London. He delivered a course of lectures at the Surrey Institution on the elements of chemical science, attended by, amongst others, the young Michael Faraday. While there, Gurney made his first invention, the oxyhydrogen blowpipe. For this he received the Gold Medal of the Society of Arts. He experimented with lime and magnesia for the production of an illuminant for lighthouses with some success. He invented a musical instrument of glasses played like a piano.In 1823 he started experiments related to steam and locomotion which necessitated taking a partner in to his medical practice, from which he resigned shortly after. His objective was to produce a steam-driven vehicle to run on common roads. His invention of the steam-jet of blast greatly improved the performance of the steam engine. In 1827 he took his steam carriage to Cyfarthfa at the request of Mr Crawshaw, and while there applied his steam-jet to the blast furnaces, greatly improving their performance in the manufacture of iron. Much of the success of George Stephenson's steam engine, the Rocket was due to Gurney's steam blast.In July 1829 Gurney made a historic trip with his road locomotive. This was from London to Bath and back, which was accomplished at a speed of 18 mph (29 km/h) and was made at the instigation of the Quartermaster-General of the Army. So successful was the carriage that Sir Charles Dance started to run a regular service with it between Gloucester and Cheltenham. This ran for three months without accident, until Parliament introduced prohibitive taxation on all self-propelled vehicles. A House of Commons committee proposed that these should be abolished as inhibiting progress, but this was not done. Sir Goldsworthy petitioned Parliament on the harm being done to him, but nothing was done and the coming of the railways put the matter beyond consideration. He devoted his time to finding other uses for the steam-jet: it was used for extinguishing fires in coal-mines, some of which had been burning for many years; he developed a stove for the production of gas from oil and other fatty substances, intended for lighthouses; he was responsible for the heating and the lighting of both the old and the new Houses of Parliament. His evidence after a colliery explosion resulted in an Act of Parliament requiring all mines to have two shafts. He was knighted in 1863, the same year that he suffered a stroke which incapacitated him. He retired to his house at Reeds, near Bude, where he was looked after by his daughter, Anna.[br]Principal Honours and DistinctionsKnighted 1863.
