Modernized Steam Engine Project Plan

Please delete this once you read it, so his email is not on the wiki without permission - thx

Analysis of alternatives:
- Researched bump valve reliability, researching alternative solutions
- Need to discuss condensation issue and air compression issue on the return stroke (sending note to M. Norton)
- Power vs pressure: The higher the pressure, the smaller and lighter the engine (weight to power ration)...optimum pressure for SWAP requirements?? Include risk analysis (higher pressure/heat = higher safety risks), probable effect on cost. Continue researching.
Reviewing Green Steam Engine products; available at http://greensteamengine.com/products.htm The 2 cylinder product provides 10 hp at 125 psi, 1500 rpms; drawings/instructions/hard to find parts available for purchase. Other products available via COTS: http://greensteamengine.com/

Updated project plan general requirements/specs and better defined FMECA process
Continued researching alternatives to issues with OSE Arrow Head Engine
Explored differences in V-shaped layout/feasibility; assessing

Contacted Mark Norton; directed to https://sites.google.com/site/phase3project/projects/steam-engine/engine-designs/ose-arrow-head-engine
Began researching the following issues with the OSE Arrow Head Engine:
- Water might condense in the cylinder chamber resulting in a blow-out condition
- Power output will be low unless operated at high speed and high steam pressures
- Bump valves are subject to wear and breakage
- Air is compressed on the return stroke, losing valuable work
- Horizontal layout leads to excessive wear on parts (piston rings, etc).

Re-baselined project focus to include work performed by Mark Norton
- Reviewed OSE Modern Steam Engine documentation and requirements, incorporated into project plan
