History
The company Price Induction was founded by Jean and Bernard Etcheparre who created and developed the companies Lectra Systèmes et Brigantine Aircraft. In 1996 and 1997 the design of an engine intended for light jets appeared to be a particularly promising subject and analytical studies were started. After three years of preparation which ended with the birth of the DGEN concept, it was decided to launch a development program based on it.
