From: cs126061@cs.brown.edu (David M. Suarez) I am looking for the types of engines used by the AH-1, OH-58, and OH-6, and/or their manufacturers. I would also appreciate the engines' specs (or some literature on them). Also, I have some helicopter engine questions: 1. Can a turboshaft engine be modelled with the same equations as a turboprop? 2. Would anyone know of any literature on modeling helicopter engine performance? (along the lines of mathematical equations for sfc and thrust, etc) 3. Would anyone know how to calculate pressure losses through the inlet particle separator? I'd appreciate any information. Thanks a lot! \David M. Suarez
