Stuart Davies (engineer)

Stuart Duncan Davies CBE FEng FRAeS (5 December 1906 – 22 January 1995) was a British aerospace engineer who was in charge of the design of the Avro Vulcan. He was also responsible for converting the unsuccessful two-engined Avro Manchester into the four-engined Avro Lancaster.

Early life

He was the son of William Davies and Alice Duncan. He attended Westminster grammar school in central London from 1918 to 1923.

Career

Vauxhall

His career began at Vauxhall Motors where he worked for two years from the age of 16.

Vickers

Avro Lancaster

He worked at Vickers as a junior technical assistant from 1925 and gained an external BSc degree in Engineering at Northampton Polytechnic (now City University London) awarded by the University of London. At Vickers he worked in the wind tunnel at Brooklands, and on the Virginia biplane bomber, converting it from a wooden to metal structure.

Hawker

In 1931 he moved to Hawker Aircraft at Kingston upon Thames. He worked in the stress office, in a team of seven. There he worked on the Hart and Fury biplanes; the RAF's main fighter planes in the 1930s. In 1933 he began work on what would become the Hawker Hurricane, then known as the Fury Monoplane.

Avro

Hawker Siddeley was formed in 1935, and in the group it included A.V.Roe & Company of Manchester. In January 1938 he moved to Avro, becoming assistant to the chief designer. Aged 33, he was promoted to be the company's experimental manager in April 1940. In 1940 he became responsible for converting the Manchester into the Lancaster. 7,377 Lancasters would be built in the UK and Canada, having first flown at Woodford on 8 January 1941.

Change in shape of the Vulcan's wing

From 1944 he was in charge of the Avro York transport plane, and later worked on the Avro Lincoln.

In 1947 he became the technical director at Avro, with responsibility for producing the Avro Vulcan (Avro 698), which first flew on 30 August 1952. He was Chief Designer from 1945–55, and was succeeded by Roy Ewans. Five Avro 707 aircraft were produced before the Vulcan. They were used for experimental work on the delta wing.

He also designed the Avro Athena advanced single-engined trainer.

Proposed Avro Atlantic airliner: perhaps Concorde started life here

The Avro Atlantic was an early-1950s proposed 94-seat airliner version of the Vulcan, with delta wings and Olympus engines, which was never built.

Later career

He left Avro in June 1955 for Dowty Rotol,^[1] becoming Managing Director of Dowty Fuel Systems in Cheltenham, and returned to Hawker Siddeley Aviation from 1958-64. He left aviation for general engineering.^[2] He was President from 1971-2 of the Royal Aeronautical Society. In 1958 he received the RAeS Gold Medal. He became an FEng in 1977. He was an honorary Fellow of the RAeS.
