Frank Whittle

By Lin Yue

Frank Whittle was twenty-two, a Royal Air Force cadet, when he wrote the thesis that contained the future. The 1928 paper, 'Future Developments in Aircraft Design,' argued that piston engines and propellers had reached their limit, and that flight at high altitude and high speed would require a turbine driven by its own exhaust, compressing air, burning fuel in it, and blasting it out the back. The idea had been sketched before, but Whittle worked out the thermodynamics and, in January 1930, patented the turbojet. Born in Coventry in 1907, the son of a mechanic, Whittle talked his way into the RAF as an apprentice, earned a cadetship at Cranwell, and became both a pilot and an engineering officer. The Air Ministry read his patent and filed it away. Private investors did not. In 1936, with two former RAF officers, he founded Power Jets, and in a borrowed foundry in Rugby his team built the first Whittle engine, the WU. On April 12, 1937, it ran for the first time, screaming on its test bed; Whittle, watching the turbine hold together, wept. The Air Ministry, belatedly alarmed by German work on the same principle, finally funded him. On May 15, 1941, the Gloster E.28/39, powered by a Whittle W.1, took off from Cranwell and flew for seventeen minutes, the first flight of a British jet aircraft. Germany's Hans von Ohain had flown nine months earlier, independently, but it was Whittle's patents and engines, shared with America, that powered the Allied jet program: the Gloster Meteor, the first Allied operational jet fighter, and, through General Electric's licensed copies, the first American jets. Whittle was knighted, promoted to air commodore, and then slowly sidelined by the bureaucracy he had forced into the jet age. He emigrated to the United States in 1976, became a professor at the Naval Academy, and died in Maryland in 1996. Every airliner in the sky is a descendant of the engine that screamed in a Rugby foundry. The war gave Whittle's engine its proving ground. The Gloster Meteor entered service in 1944 and was used against the German V-1 flying bombs, the first jet-versus-jet-era combat in history, though the Meteors never met their German counterparts in battle. Power Jets was nationalized in 1944, and Whittle, exhausted and increasingly at odds with the bureaucracy, resigned from the RAF in 1948 with the rank of air commodore. A grateful nation voted him 100,000 pounds through the Royal Commission on Awards to Inventors, and he was knighted the same year. But the jet age he had created moved on without him, and he watched from the sidelines as the industry commercialized his invention. In 1976 he emigrated to the United States, where he became a research professor at the Naval Academy in Annapolis, finally treated as the founding figure he was. American engineers, who had built their jet industry on his shared patents, honored him more readily than his own country had. He died in Maryland in 1996, having lived to see the turbojet's descendants, the high-bypass turbofans, carry hundreds of millions of passengers a year. The parallel story belongs to Hans von Ohain in Germany, who flew first but whose designs led nowhere after the war; it was Whittle's patents, freely shared with the Allies, that became the foundation of the global jet industry.

Impact on civilization

The turbojet collapsed distance. Before it, crossing an ocean took days by propeller airliner or weeks by ship; after it, continents became commutable, and the global economy reorganized itself around the assumption that people and high-value goods could be anywhere on earth within a day. Commercial aviation, air freight, the tourist industry, the military doctrine of air power, the gas turbines that now generate a significant share of the world's electricity, all descend from Whittle's compressor-turbine loop. His career is also a case study in institutional blindness: the invention that defined the second half of the twentieth century was patented by a twenty-two-year-old, ignored by his own air force for a decade, and built with private money in a borrowed workshop. The jet engine's second-order effects reach far beyond aviation. The gas turbine, Whittle's compressor-turbine loop adapted for stationary use, now generates a large share of the world's electricity and powers naval vessels and pipeline compressors. The engine also compressed military geography: air power became global power, and the strategic map of the Cold War was drawn in the range circles of jet bombers and tankers. Commercially, it created the hub-and-spoke airline system, the package-tour industry, and the expectation that distance is a minor inconvenience, assumptions now so embedded in the world economy that their inventor is invisible.
