The SNECMA ATAR is a French axial-flow turbojet engine built by Snecma. It was derived from the German World War II BMW 018 design, and
developed by ex-BMW engineers, among them pioneering Dr Hermann Östrich who participated in the design of the BMW 003 engine, through a
progression of more powerful models. The ATAR name is derived from its original design group, Atelier Technique Aéronautique
de Rickenbach near Lindau within the French Occupation Zone of Germany.
In October 1945, Dr Östrich is invited by French Authorities to come to work in France with SNECMA. Assisted with a good hundred
other engineers, he then started to work on a development of the BMW 003 engine for which the French Government ordered six test
examples. The engine was named ATAR 101, and the targeted thrust was 2000 kgp. The first prototype of the engine (101.V1 or A1)
was tested at 1700 kgp on March 26, 1948, and the second prototype at 2200 kgp on April 15, 1948
