Re: Engine Indicators, Power, Tuning

This Prony Brake was actually made to find the horsepower of a small uniflow steam engine. It worked very well, but several graduate engineers at a large firm specializing in power plant design, could not find any answer to the stated question! Alright, I'm intrigued. What's the question?

Valvegear Simulation Software

I don't know if this is well known, but I recently found a website (http://www.billp.org/Dockstader/ValveGear.html) with software available for simulation of more or less every valve gear ever used. It's meant for use with the live steam community but it's still been pretty useful for me, hopefully ...

Re: Steam Actuated Inlet Valves?

Skinner of course used two cams running running at the same speed, and adjusted the phase angle between the cams to achieve a wide range of cut-offs, from 5 or 10% to over 50% - necessary since those engines were often used in direct reversing marine service, and reliable reversing is essential.
