Increasing The Submerged Endurance Of a Naval Submaring Using A Synthetic Atmosphere Diesel

At spasmodic intervals since the turn of the century attempts have been made to develop Synthetic Atmosphere Diesels(SAD) for underwater use. Until recently these attempts have not been successful. However, technical breakthroughs over the last ten years have enabled SAD systems to be once again developed for use in submarines. In this Paper the design of such engines is described; a brief development review is presented and the potential benefits in terms of enhanced submerged to be gained from SAD use are outlined
