Hello. I will keep it short. I trying to find sources for a school engineering project on the S62 Engine. I am trying to findpre information on the history of the engine and the people involved when it was designed and created. Im also trying to find techincal specs. Does anyone know where I can find some good sources that arent just wikipedia.
