Jet Source Inc. history

In 1917, at a time when there was a general lack of interest in superchargers, Sanford Moss pioneered the development of a turbo supercharger, a turbine that utilized the waste gases in the engine exhaust, a concept first advanced by the Frenchman Auguste Rateau.

In 1930 the piston engine was the only powerplant available to aircraft designers.

Hans von Ohain worked on a similar design in 1935.

His first engine was up and running in April 1937.

One of the important reports issued by the NACA in 1939 concerned a method for predicting how much engine temperatures would fluctuate as the ambient air temperature changed.

In 1940 the sections within Langley's Power Plants Division reflected the conventional, incremental approach to the reciprocating engine.

In June 1942, Vannevar Bush raised doubts about the wisdom of exclusive reliance on the axial compressor.

Classification of the Whittle project was downgraded from "supersecret" to "secret" in summer 1943.
