Hi group:

This question is regarding the horsepower rating of the Walter = engine(s). The published take-off horsepower rating for = the 601E is=20 751 shaft horsepower (SHP). This can be found at the water web = site www.walterengines.com . My = understanding=20 of turboprop engines is that they generate their power primarily in = the=20 form of torque applied to the propeller. This is referred to shaft = horse=20 power (SHP). In addition to this, power is generated by the = jet=20 exhaust from those bent pipes near the front (which is really = the=20 back) of our engines. These two ratings are added together = and=20 referred to as "equivalent shaft horsepower" (ESHP). This can = be seen=20 in the Pratt & Whitney web site in reference to the PT6=20 engines which are rated "580 to 920 ... ESHP" = or equivalent shaft=20 horsepower www.pwc.ca . My=20 question: Are the horsepower ratings for the Walter engines = "SHP" or=20 "ESHP"?
