Career at Supermarine


Early career and promotion

In 1916, Mitchell joined the Supermarine Aviation Works at

, producing its first aircraft, the Pemberton-Billing P.B.1, in 1914. During the First World War, Supermarine was taken over by the British Government, and during this period the company produced the first British single-seat flying boat fighter, the Supermarine Baby. On joining the company, Mitchell was given the opportunity to develop skills in a number of roles, so as to gain experience of the aircraft industry. His basic engineering training would have helped him to become established, as he adjusted from working with locomotives to understanding aeroplanes. A competent mathematician, Mitchell's ability to think creatively and use his intuition when looking at a design was soon recognised. The earliest record of his work at Supermarine is as a

, and was renamed the Supermarine Sea Lion. In 1918, Mitchell was promoted to become the works manager's assistant. When Supermarine’s chief designer William Hargreaves left the company in the summer of 1919, he was replaced by Mitchell, who took up his new duties later that year, leading a team that had in 1918 consisted of six draughtsmen and a secretary. Following his promotion, the 19-year-old returned to Staffordshire and married his fiancé Florence Dayson, an infant school headmistress, who was 11 years his senior. By 1921 he had become Supermarine's chief engineer. Following the departure of Scott-Paine in November 1923, Mitchell was able to negotiate a new contract, which led to greater influence in the company. The 10-year contract was a sign of his indispensability to Supermarine. It is unclear how Mitchell came about to become so quickly promoted when he was still a young man, as few documents relating to his early career have survived. However, his early promotion was not usual at that time; other men of Mitchell's age held similar positions in other aircraft companies. Decades after his death, when approached for information about him, those surviving Supermarine colleagues who had known Mitchell were reluctant to recall their personal memories.


1920s civilian and military aircraft designs

Between 1920 and 1936, Mitchell designed 24 aeroplanes. His early projects often involved adapting Supermarine's earlier aircraft; in June 1920 the Air Ministry announced a civilian aircraft competition, and Supermarine's entry for the competition was the Commercial Amphibian, an adaptation by Mitchell of the company's Supermarine Channel. The Amphibian finished second, but was judged the best of the three entrants in terms of design and reliability. His redesigned Supermarine Baby, renamed the

. The Southampton was one of the most successful flying boats of the between-war period, and established Britain as a leading developer of maritime aircraft. It was used to equip six RAF  squadrons up to 1936. In 1926, the Air Ministry issued specification 21/26 as a way to address the need for new fighter aircraft, and Mitchell's design team, which he had re-organised that year into separate drawing and technical offices, responded with a number of designs, including the Single Seat Fighter. By this time, Supermarine was moving away from wooden

, and a new design, the Southampton X (not related to other planes with the same name), was ordered in June 1928. Mitchell dispensed with the complicated curved surfaces for the wings and the hulls of the Air Yacht and the Southampton X, and as a result these aircraft appeared "boxy". Specification R.6/28, issued in 1928, resulted in a series of designs by Supermarine for a six-engined flying boat, with one of designs being a radical departure for Mitchell—it had a newly-designed

with a large surface area and cross section. The aircraft was never built. From 1929 to 1931, he continued to design aircraft based on the Southampton and the Southampton X, such as the Supermarine Sea Hawk and its variant the Sea Hawk II, the Type 179, the Nanok and the Seamew.


New designs, production orders and patents (19291934)

, produced in April 1934, which was never put up for tender. During the early 1930s, many of Mitchell's ideas never went past the early design stages. Attempts by the company to sell a 5-engined flying boat failed when a contract was cancelled in early 1932, leading to job losses and wage cuts at Supermarine. However in 1933 the company's fortunes were revived when it received an order for 12 Scarpas (previously the Southampton IV) under the specification R.19/33, the first contract for a new design by Mitchell since 1924. This order was followed by orders for the

, Lady Houston, who donated after the British Government decided not to enter an RAF team for the 1931 contest. Mitchell opted to design an improved version of the S.6, whilst making as few changes as possible. The improvements that were made included a more powerful engine, and provision was made for such effects as the increase in engine-produced heat and extra torque, and the greater quantities of cooling oil and fuel required. The S.6B was a larger seaplane than the S.6, and had to be given a more efficient cooling system, and a stronger frame. The S.6B competed the course successfully, and won the 1931 race. As the Schneider Trophy rules included the stipulation that the contest would end when any one country managed to win the trophy three times in five years, the S.6B's victory won the contest outright for Britain. The aircraft went on to break the world air speed record when it reached a speed of that year. Mitchell was awarded the Commander of the Most Excellent Order of the British Empire (CBE) on 29 December 1931 for services in connection with the Schneider Trophy contest.


Type 224

In 1930, specification F7/30 was issued for a fighter aircraft able to be used by both day and night squadrons. Mitchell's proposed design, the Type 224, was one of three monoplane designs made into prototypes for the Air Ministry. The final design incorporated an open cockpit, four

engine, along with a fixed undercarriage. Also included was an inverted gull wing, needed due to the demands of the engine's cooling system. The wing lacked flaps, a requirement for the aircraft to land at safe speeds. Unofficially named the Spitfire, the Type 224 first flew on February 1934. The aircraft looked clumsy, and was inefficient, in part because the cooling system failed to prevent the engine from overheating. The RAF decided that the Type 224's performance was unsatisfactory, and selected the

engine, and by making use of an innovative new cooling system—the latter being an example of his willingness to accept ideas from other people. For a short period, design work continued using private funding, but in December 1934 the Air Ministry contracted Supermarine to construct a prototype that was based on Mitchell's design. Mitchell objected to the Air Ministry's insistence that the Spitfire be modified to have a

Mitchell's achievement lay in the merger of these different influences into a single design, originating from his "unparalleled expertise in high-speed flight... and a brilliant practical engineering ability, exemplified in this instance by the incorporation of vital lessons learned from Supermarine's unsuccessful type 224 fighter". The quality of the design enabled the Spitfire to be continually improved throughout World War II.

Personality

Mitchell was by nature a reserved and modest man. He was a reticent public speaker who disliked presenting papers. According to one member of his department, "he said nothing unless there was something worth saying". He avoided publicity, and was not widely known to the general public until after his death. According to his son Gordon, Mitchell was resentful of authority being imposed on him or of the routines of the workplace, and was short-tempered and "a difficult man to live with sometimes". Often given full scope at Supermarine, he was a strict taskmaster who nevertheless struggled with the level of organisation needed for a company such as Supermarine. When the engineer

was employed to improve the efficiency of Mitchell's department in 1930, Wallis had to be recalled after their personalities clashed. The ''ODNB'' describes Mitchell as being highly gifted and intelligent, but someone who was "often stern and irascible towards those less gifted than himself". He was devoted to his staff at Supermarine, to whom he showed kindness and humanity, and they in turn repaid him with loyalty and affection.
