Introduction and Outline
1. Model of the Wildfire Spacecraft
2. Overview of CAD using Inventor– Parametric Modeling– Advanced Parameter Control
3. Optimization Process– Closing the design loop
1. Model of the Wildfire Spacecraft
The CAD Model serves several purposes:
a) Visualization
b) Determine mass & moments of inertia
c) Geometry for FEA Analysis
d) Final Production Drawings

2. Overview of CAD using Inventor
Inventor is a fully parametric modeling environment
This means that part dimensions can be linked, and made interdependant
2. Overview of CAD using Inventor
This Dimension sets the height of
the truss
Parameterization In Action
Truss in rocket block connecting the solid motor to the primary fuel tank
2. Overview of CAD using Inventor
Parameterization In Action
Changing this dimension modifies
the entire truss.

2. Overview of CAD using Inventor
Advanced Parameters Control:
• AutoDesk Inventor can link all of its parameters to a spreadsheet
• Using excel, a parameter control sheet is created which contains all the dimensions which affect the model
• This sheet, instead of part specific dialog boxes, is where modifications to dimensions are made

3. Optimization Process
• Design optimization is achieved by iteration
• Results from one level of analysis are used to refine the next level.
3. Optimization Process
Main tools in the design process
– Matlab Simulation– Inventor CAD– Ansys FEA Analysis
Integration is achieved by linking the outputs and inputs of these tools using spreadsheets

3. Optimization Process
Closing the Design Loop
• The Forward flow of design parameters ensures consistency
• Adding feedback allows the design to converge to an optimal point
3. Optimization Process
• Current level of Integration :– Feedback between the Simulation and
CAD Model– Direct use of CAD Model in FEA using
Ansys Design Space
• Target Level:– Full Integration
