SNAP Integration Model V. S14 About this Model
The current model has evolved in response to the project design flow. In its present form it
• Provides a real-time snapshot of our combined thinking.
• Becomes a Test-bed for detailed Trade studies.
• Reveals immediate system interactions.
• Brings all subsystems and mission objectives into one, tangible workspace.
SNAP Integration Model V. S14 How it works
Weekly Engineering meetings hosted by Pankow at SSL or Lafever at LBNL.
The Intent:
• All systems are represented.
• Designs and Studies are initiated, teams form, effort goes off-line.
• Results from earlier studies are reported, changes adopted, production goes off-line.
• “Hot” concerns get focused attention first.
The Effect:
• Technical studies get tested as soon as they can be articulated.
• Model updates and studies are iterated on a 1 to 3 week cycle.Detail is sacrificed for speed.
• Detailed studies are iterated on a 1 to 3 week cycle and incorporated into the model. Speed is sacrificed for detail.
• Multiple ‘Fitup’ models can tolerate simultaneous development.
• Integration models can be assembled at any time !

SNAP Integration Model V. S14 Deliverables
The ModelsThe Assembly presented here, along with tooling, fiducials, and variations are available as 3d CAD models, and can be exported in a variety of formats. (earlier studies have been carried to NASA-IMDC and back, for example)FEA models are also available
The GraphicsScreen shots, and Hi-res graphics are packaged as Web-available files in a variety of formats that feed directly into ongoing presentations, such as this one.
Engineering modelsLow cost study models are already in the worksMock-ups and study models, and exemplars exist alreadyAnd, John Bercovitz and Chris Bebek have examples of the REAL thing ! A “get yer hands in it !” scale mockup of the Optical Bench, andRapid Prototype detail models are being developed right now.
