Timeline of Jet Power - 1939, Flight

1939, Flight

• Arkhip Mikhailovich Lyulka develops early turbofan engine at Kharkov Aviation Institute.
• A stationary gas turbine is installed in a new electrical generating plant in Neuchâtel, Switzerland.
• A 2,200 horsepower (1,600 kW) gas turbine is built by Asea Brown Boveri and used to power an experimental train in Switzerland.
• BMW's team led by Hermann Östrich tests their axial-flow design.
• Bramo starts work on two axial-flow designs, the P.3301 and P.3302. The P.3301 is similar to Griffith's contrarotating designs, the P.3302 using a simpler compressor/stator system.
• Bramo is bought out by BMW, who abandon their own jet project under Östrich, placing him in charge of Bramo's efforts.
• Summer: Jumo is awarded a contract to develop an axial-flow engine, starting work under Anselm Franz. Müller decamps with half the team to Heinkel.
• Frank Whittle's patent drawing for his engine is published in the German magazine Flugsport.

• August: Heinkel He 178 V1, the first jet-powered aircraft, flies for the first time, powered by the HeS 3B.
• September: A team from the Air Ministry visits Power Jets once again, but this time Frank Whittle demonstrates a jet engine at full power for a continuous 20-minute run. They are extremely impressed, and immediately offer contracts to Whittle to develop a flyable design, and production contracts are offered to practically every engine company in England. These companies also set up their own design efforts, making the possibility of financial rewards for Power Jets slim.
• September: The Air Ministry also contracts Gloster to build an experimental airframe for testing Whittle's engines, the Gloster E.28/39
• After hearing of Whittle's successful demonstration, Hayne Constant realizes that exhaust thrust is practical. The Metrovick efforts are immediately reworked into a turbojet design, the Metrovick F.2.
• November: Müller's team restarts work on their axial-flow design at Heinkel, now known as the Heinkel HeS 30.
• René Anxionnaz of France's Rateau company received a patent on an advanced jet design incorporating bypass.
• Leist joins Dailmer-Benz and starts work on an advanced contra-rotating turbofan design, the DB 6001
• A shakeup at the RLM's engine division places Helmut Schelp in control, and results in development contracts for all existing engine designs. The designs are also given consistent naming, the Heinkel HeS 8 becoming the 109-001, the HeS 30 the -006, BMW's efforts the -002 and -003, and Jumo's the -004. Porsche's project becomes the -005, although work never starts on it. DB gets -007. Numbers starting in the 20s are saved for turboprops, and 500 and up for rockets.
