Blade-Off Assessment Checklist
Checklist for blade-off structural and containment assessment covering imbalance, casing response and containment.
Imbalance
- Imbalance force computed (m * omega^2 * r_cg)
- Transient bearing loads assessed
- Shaft dynamic response from rotordynamics
Casing and mount
- Casing stress from transient bearing loads
- Mount loads within support capacity
Containment
- Fragment energy computed
- Explicit FEA of blade impact on casing
- No penetration (containment confirmed)
- Test correlation available or planned
