Elastic Straps for Stator Position Retention

The stator assembly incorporates elastic straps that allow dynamic adjustment of stator position. The elastic material enables the stator to move slightly in response to vibration and thermal expansion while maintaining controlled clearance, transforming the rigid fixed-tolerance system into a dynamically adaptable one.

The elastic straps change their mechanical properties (flexibility, tension) in response to operating conditions. As temperature and vibration levels change, the elastic material adjusts its deformation characteristics, allowing the stator position to adapt while maintaining manufacturing precision within acceptable ranges.

The elastic straps provide dynamic clearance control that adjusts the gap between stators and rotor blades based on operating conditions. During vibration and thermal expansion, the elastic material deforms to maintain optimal clearance, preventing excessive gaps that would cause air leakage while allowing sufficient movement range.

The elastic straps are pre-tensioned to continuously push the stators toward their optimal position, counteracting the tendency for gaps to open up during operation. This preliminary active force prevents air leakage by maintaining contact or near-contact between stators and rotor blades even as thermal expansion and vibration occur.

The elastic straps utilize flexible elastic material to provide the necessary adaptability and vibration damping. This flexible element approach achieves complex functionality (clearance control, vibration isolation, position retention) without requiring complex mechanical mechanisms, multi-component assemblies, or sophisticated control systems.

The elastic straps perform multiple functions simultaneously: they provide vibration damping, maintain stator position retention, control clearance gaps, and accommodate thermal expansion. This multi-functionality reduces overall device complexity by consolidating what would otherwise require separate components for each function.
