Concerns with original welded design
Perforated skin
Partitions welded to
skin and inner wall
Inner wall
Hollow interior
ERMC solution – partitions machined into thick wall tube
Benefits
- Leakage between partitions
- Irregular rotational balance
- Distortion due to welding
- Eliminated leakage between partitions
- Improved rotational balance with
consistent weight distribution - Eliminated weld distortion
