Isolation System: Fundamental Requirements
- Locate and support powertrain mass
- React external and internal forces without interference
- Isolate external and internal forces
- Must perform under severe conditions and provide fail safe
- Manufacturability
- Robustness
- Assembly/maintainability
- Weight and cost must meet program objectives
Defense-Specific Engine Mounting Challenges
- Power Dense Engine = Higher Forces reacted through less mass
- Tight deflection envelope
- Limited freedom/flexibility for isolator placement
- Substantial mobility, transportation and shock requirements
- Structural rigidity?
- Hardware delivery while design is still in-flux
- Aggressive exterior acoustic requirement, interior must be inhabitable
