Alan Arnold Griffith was much a "boffin", for he was a quiet, thoughtful man who shunned public appearances, yet he produced revolutionary ideas. During World War I he worked at the Royal Aircraft Factory, Farnborough, where he carried out research into structural analysis. Because of his use of soap film 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 in Farnborough. In 1929 he made proposals for a gas turbine driving propeller - a turboprop, but the idea was shelved. In the 1930s he was head of the RAE Engine Department and developed multi-stage axial compressors, which were later used in jet-engines. This work attracted the attention of Rolls-Royce who persuaded Griffith to join in 1939. His first project was a "contra-flow" jet engine, which was a good idea but a practical failure.

Griffith experimented with suction to control the boundary layer of wings, but his main interest in the 1950s centered on vertical-take-off and -landing aircraft. He developed the remarkable "flying bedstead" consisting of a framework in which two jet engines were mounted with their jets pointing downwards, thus lifting the machine vertically. It first flew in 1954 and provided valuable data. The Short SC 1 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. Griffith proposed an airliner with lifting engines, but the weight of the lifting engines when not in use would have been a serious handicap. Griffith retired in 1960. He was awarded the CBE title in 1948, was elected a Fellow of the Royal Society in 1941; he received the Silver Medal from the Aeronautical Society in 1955, and the Blériot Medal in 1962.
