16 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 -

18 Ricardo, Sir Harry Ralph
[br]b. 26 January 1885 London, Englandd. 18 May 1974 Graffham, Sussex, England[br]English mechanical engineer; researcher, designer and developer of internal combustion engines.[br]Harry Ricardo was the eldest child and only son of Halsey Ricardo (architect) and Catherine Rendel (daughter of Alexander Rendel, senior partner in the firm of consulting civil engineers that later became Rendel, Palmer and Tritton). He was educated at Rugby School and at Cambridge. While still at school, he designed and made a steam engine to drive his bicycle, and by the time he went up to Cambridge in 1903 he was a skilled craftsman. At Cambridge, he made a motor cycle powered by a petrol engine of his own design, and with this he won a fuel-consumption competition by covering almost 40 miles (64 km) on a quart (1.14 1) of petrol. This brought him to the attention of Professor Bertram Hopkinson, who invited him to help with research on turbulence and pre-ignition in internal combustion engines. After leaving Cambridge in 1907, he joined his grandfather's firm and became head of the design department for mechanical equipment used in civil engineering. In 1916 he was asked to help with the problem of loading tanks on to railway trucks. He was then given the task of designing and organizing the manufacture of engines for tanks, and the success of this enterprise encouraged him to set up his own establishment at Shoreham, devoted to research on, and design and development of, internal combustion engines.Leading on from the work with Hopkinson were his discoveries on the suppression of detonation in spark-ignition engines. He noted that the current paraffinic fuels were more prone to detonation than the aromatics, which were being discarded as they did not comply with the existing specifications because of their high specific gravity. He introduced the concepts of "highest useful compression ratio" (HUCR) and "toluene number" for fuel samples burned in a special variable compression-ratio engine. The toluene number was the proportion of toluene in heptane that gave the same HUCR as the fuel sample. Later, toluene was superseded by iso-octane to give the now familiar octane rating. He went on to improve the combustion in side-valve engines by increasing turbulence, shortening the flame path and minimizing the clearance between piston and head by concentrating the combustion space over the valves. By these means, the compression ratio could be increased to that used by overhead-valve engines before detonation intervened. The very hot poppet valve restricted the advancement of all internal combustion engines, so he turned his attention to eliminating it by use of the single sleeve-valve, this being developed with support from the Air Ministry. By the end of the Second World War some 130,000 such aero-engines had been built by Bristol, Napier and Rolls-Royce before the piston aero-engine was superseded by the gas turbine of Whittle. He even contributed to the success of the latter by developing a fuel control system for it.Concurrent with this was work on the diesel engine. He designed and developed the engine that halved the fuel consumption of London buses. He invented and perfected the "Comet" series of combustion chambers for diesel engines, and the Company was consulted by the vast majority of international internal combustion engine manufacturers. He published and lectured widely and fully deserved his many honours; he was elected FRS in 1929, was President of the Institution of Mechanical Engineers in 1944–5 and was knighted in 1948. This shy and modest, though very determined man was highly regarded by all who came into contact with him. It was said that research into internal combustion engines, his family and boats constituted all that he would wish from life.[br]Principal Honours and DistinctionsKnighted 1948. FRS 1929.
