Warfare and wind tunnel: engineers, physicists, and the evolution of combat aircraft 1914-1918

Abstract The British aircraft industry was transformed across the course of the First World War. Annual output grew exponentially, while by 1917-1918 the intensity of wartime research and development saw technologically advanced machines seeking air supremacy in all theatres of operation, most notably the Western Front. Capability had been inhibited by the absence of reliable, high performance power units, but ultimately production and procurement problems were resolved. This heroic narrative warrants qualification given the high ratio of poor to outstanding aircraft and the reality that in August 1914 Britain was by no means wholly unequipped to wage war in the air: the development programmes of the National Physical Laboratory and Royal Aircraft Factory, and the Royal Naval Air Service’s collaboration with science-based companies such as Short Brothers run counter to a popular belief that machines were still crudely built and militarily ineffective. There existed a working partnership between pioneer engineers and designers, schooled in applied science at metropolitan technical colleges, and graduate physicists and mathematicians encouraged by far-sighted dons to join a fledgling but fast-growing industry. That fusion of theory and practice, academic and industrial, was consolidated once British science’s human assets were mobilised to wage ‘industrial war’. Yes, aviation saw huge changes across the War, but the continuity is striking: before 1914 designers and air frame manufacturers were drawn from both the shop floor and the varsity, a wartime infusion of research scientists generated remarkable advances in aeronautics and in consequence a vital extension of Allied air power; and after 1918 companies survived retrenchment thanks to a durable combination of the entrepreneurial engineer and the experimental analyst.
