The Man Who Shrank the Globe – Frank Whittle

Frank Whittle (1907 – 1996)

On August 9, 1996 the British Royal Air Force engineer officer Sir Frank Whittle passed away. He was best known for inventing the turbojet engine for which he received the knighthood in 1948.

Well, that’s what it was bloody well designed to do, wasn’t it? – Frank Whittle

Thanks to Whittle’s father Moses, Frank was able to get an early insight in the field of engineering and mechanics. The family bought a company where Frank could get lots of practical experience. He early developed a huge enthusiasm for engineering, flight, and turbines and decided to become a pilot when he was 15.

After passing the entrance test to the Royal Air Force he has been deeply disappointed, due to his height he did not pass the medical exams and even though he trained hard, he was not given a second chance. His only chance to stay in the RAF was beginning an apprenticeship to become an aircraft mechanic, which he did so. During his courses he was able to take flying lessons and soon became known as an extraordinary engineer as well as a great pilot. After his graduation he worked as a flying instructor, but destroyed two entire airplanes in accidents without getting hurt himself.

Whittle began developing new concepts for engines since working on his thesis and sent his ideas to the Air Ministry in 1929, but claiming that it was too impracticable they rejected it. However, his career went up and until 1934 he became Flight Lieutenant. In the 1930’s, Whittle was finally able to find partners, helping to finance ‘Power Jets Ldt.’ and the first tests on the engines were performed in 1937.

In April 1937 the first test runs could be held, at about the same time as Hans von Ohain‘s demonstration engine was running at Heinkel in Marienehe. The engine proved to be difficult to regulate and was destroyed several times during the test runs. Despite all this, the Air Ministry became aware of this project and supported it with £6,000, after which the test stand was moved to an old factory building in nearby Lutterworth. Finally, in March 1938, a completely satisfactory test run was carried out. The rule problems were overcome. After the outbreak of World War II, the Ministry of Aviation ordered the construction of a jet-powered aircraft in which Whittle’s company was to supply the engine and Gloster the airframe.

Work progressed rapidly and already on May 15, 1941 at 7:40 a.m. local time the experimental aircraft Gloster E.28/39 took off from Cranwell airport. 1½ This was the first flight of a jet propulsion aircraft worldwide with the German He 178, the first flight of a British jet aircraft. The machine was driven by a Whittle Supercharger type W.1 with 3.8 kN thrust. This engine already used kerosene as fuel. During the 17-minute test flight of RAF test pilot Gerry Sayer, the aircraft reached a top speed of 545 km/h. With the improved W.2 engine with 7.6 kN thrust, speeds of up to 724 km/h were later achieved with this aircraft. Convinced of the tests, the Ministry of Aviation ordered a twin-engine fighter, the later Gloster Meteor, from BTH. Whittle went to the United States in 1942 to help General Electric develop its own jet engine. From this program arose the Bell P-59 Airacomet, which had its first flight in autumn 1942. Whittle then returned to England to work for Rolls-Royce. He led the design and development of the engines. Whittles company was nationalized and was called Power Jets from then on. The big success has been globally noticed and Whittle worked in the United States for some months to help constructing the jets, but came back to England to work for Rolls Royce.

Whittle retired from the RAF in 1948 with the rank of Air Commodore and later became a consultant at BOAC. Finally he emigrated to the USA in 1976, where he took over a professorship at the United States Naval Academy in Annapolis. Frank Whittle was honored numerous times, such as receiving the knighthood and the James Watt International Medal. He had invented the jet engine independently and at the same time as German engineer Hans von Ohain.[7] Later in their life in the 1960s both inventors maintained a deep and lifelong friendship.
