Context: "Sir Frank Whittle, an English engineer, is credited with inventing the jet engine. He patented the design for the turbojet engine in 1930, and his work led to the first operational jet engine in 1937. Independently, Hans von Ohain in Germany developed a similar jet engine, with the first flight powered by his design occurring in 1939. Both are recognized for their pioneering contributions, but Whittle's work laid the foundational concepts."

All modern jet engines are based on Ohain's axial flow design, not Whittle's radial flow one. Ohain's engine first ran in 1937. The Heinkel HE178 was the first flying jet airplane, with Ohain's engine.

The Me262 was the first operational jet fighter, again with Ohain's engine.

I think "Ohain's engine concept" would be more correct.

Ohain worked at Heinkel and developed the HeS 011 engine. However, the Me 262 was equipped with the Junkers Jumo 004, which was based on Ohain's design, but developed without him. The first test flights were actually done in 1942 with two BMW Typ P 3302 turbines (later called BMW 003).

"Granted a patent for his turbojet engine in 1936, Ohain joined the Heinkel Company in Rostock, Germany. By 1937 he had built a factory-tested demonstration engine and, by 1939, a fully operational jet aircraft, the He 178. Soon after, Ohain directed the construction of the He S.3B, the first fully operational centrifugal-flow turbojet engine. This engine was installed in the He 178 airplane, which made the world's first jet-powered aircraft flight on August 27, 1939."

Axial flow made more demands on metallurgy of the time than centrifugal flow. The Viscount was the first turbine powered civil aircraft using RR Darts with two centrifugal compressor stages.

I enjoyed flying on the Viscount. It offered a much nicer passenger experience than the current crop of sardine cans.

Decades later I got in a lot of time flying the simulator that Air Canada donated to a tech school.
