 engine, and calculated that big improvements could be made to their efficiency. His recommendations were put into the production line for newer versions, notably the Merlin 45, improving its power by approximately 30%, and then the Merlin 61.

The Merlin 45 went into the Spitfire Mk V

 in October 1940, which was produced in the greatest number of any Spitfire variant. The two-stage supercharged Merlin 61 went into the Spitfire Mk IX, the second most-produced variant, which went into service in July 1942. The Merlin 61 arrived in time to give the Spitfire a desperately needed advantage in rate of climb and service ceiling over the Focke-Wulf Fw 190

The Focke-Wulf Fw 190 Würger was a German Second World War single-seat, single-engine fighter aircraft designed by Kurt Tank in the late 1930s. Powered by a radial engine, the 190 had ample power and was able to lift larger loads than its well-known counterpart, the Messerschmitt Bf 109...

. This variant of the Merlin was also to become the powerplant of the North American P-51 Mustang, and its efficiency enabled the Mustang to fly all the way to Berlin, attack the defending German fighters, and return home; this engine and the laminar flow Mustang wing was the secret of its success. Lee Atwood of North American Aviation made it clear that the Meredith Effect

 had more influence on the performance of the Mustang than its laminar flow wing. The Meredith Effect used the heat of the engine to produce thrust through its sophisticated radiator system.

The mathematics involved in optimising the efficiency of a supercharger, which Hooker developed, were the basis of the mathematics needed to make a gas turbine run efficiently. All jet engines, except for turbineless ones such as ram-jets, are based upon the equations used to develop the Merlin.

In 1940 Hooker was introduced to Frank Whittle

Rover was no happier with the state of affairs than Whittle. In 1942 Maurice Wilkes of Rover met Hives and Hooker in a pub. Wilkes and Hives eventually came to an agreement whereby Rover would take over production of the Rolls-Royce Meteor tank engine factory in Nottingham

On his return to England he decided that Rolls should recapture the power lead, and in 1944 the team started development of a larger version of the Derwent that was delivered as the 5500 lbf (24,465.2 N) Nene

. This did not turn out well at first, and Hooker felt he was being blamed for its problems. At the same time Rolls decided that their existing piston engines were a dead end, and moved all future jet work from Barnoldswick to Derby, their main engine site. This reduced Hooker's role in the company, and after an emotional falling-out with Hives, he left.

Bristol

In January 1949 Hooker went to work at the Bristol Aero Engine

in February 1954 due to a spur gear failure prompted a telephone call from his old boss Hives, who subsequently sent his top team of Rolls-Royce jet engineers, composed of Elliott, Rubbra, Lovesey, Lombard, Howarth and Davies, to give Hooker some desperately needed help. Sadly this was the last communication between the two great men.

The Proteus was soon in production, but did not see widespread use, and only a small number of Britannias were built. Hooker also worked on finishing the Olympus, developing later versions that would be used on the Avro Vulcan

In 1966 Bristol Siddeley was itself bought by the now cash-flush Rolls, with the result that there was only one engine company in England. After a brief period, Hooker retired in 1967, staying on as a consultant only. In 1970 he retired fully, and was upset that after almost 30 years in the industry he had never become director of engine development.

Return to Rolls-Royce

In 1971 Rolls-Royce was bankrupted by its hugely expensive RB.211 project. While trying to save the company and the project, Kenneth Keith, the new chairman who had been put in to rescue the company, persuaded Hooker to return to Rolls full-time. As technical director he led a team of other retirees to rectify the problems, and soon the RB.211 was in production. Its first application was for Lockheed's L-1011 Tri-Star

During his return to Rolls-Royce, Sir Stanley was part of several high-level trade missions to China. These led to him becoming Honorary Professor of Aeronautical Engineering at Beijing University.

In 1984, Hooker published his autobiography, Not Much Of An Engineer, referring to a quip Hives had made soon after they met.
