The Development Process

Project-Process.png

The product development process consists of the following steps:

  1. Gather Requirements
  2. Create a Design
  3. Specify What Will be Built
  4. Describe How to Build It
    1. Bill of Materials with Sources
    2. Fabrication Plan (Diagrams, CAM, CNC, etc)
    3. Assembly Instructions
  5. Prototype
  6. Final Product

The creation of a prototype will often reveal design flaws, hidden assumptions, new requirements, etc. This learning is fed back into the development process to create a new design leading to another prototype. When sufficient quality is reached, the product is released (leading to Marketing Plans, User Documentation, Production Plans, and other considerations).


Progress

  • 2/5/2009 - We are still developing a strategy for building the first steam engine. We have not decided whether we should cast the engine block or approach it by using stock tubing and parts.
  • 4/30/2011 - Project has been re-started based on dialog between Marcin and Mark Norton.
  • 5/3/2011 - Updated design goes into review at SACA.
  • 5/5/2011 - Design review input received from SACA. Bump valve spring issues lead to consideration of a piston valve control.


Unanswered Questions

  • What kind of steam control valve should we use?
  • What will be fabbed vs. bought off-the-shelf?
  • What size bore will we use?
  • Should we enclose the crankshaft for safety and mess-prevention?
  • How do we control oil flow out of the dribbler?


Design Snapshot

The following description is a summary of the current Steam Engine Design. For more details, please see Steam Engine Design.

Two designs are under active consideration with the steam control valves being the main difference:
