Aircraft Engine Gas Pipe Damper Segment for Vibration Absorption

The pipe is divided into multiple segments (rigid sections and flexible damper sections) that can be independently designed and assembled. The rigid segments provide structural strength while the flexible segments reduce weight and manage vibrations, allowing each segment to be optimized for its specific function rather than the entire pipe being uniformly rigid

The flexible damper section uses a thin-walled cylindrical structure with circumferential ridges that provides flexibility and vibration damping while maintaining sufficient structural resistance. This thin-walled design significantly reduces weight compared to a fully rigid pipe while still accommodating thermal expansion and pressure variations

The pipe transitions from a static rigid structure to a dynamic system with flexible damper sections that can adapt to thermal expansion, pressure variations, and vibrations. The flexible section's circumferential ridges allow controlled deformation and movement, enabling the pipe to accommodate thermal growth and dynamic effects while maintaining pressure containment

By segmenting the pipe into rigid and flexible sections, the rigid segments maintain pressure resistance while the flexible segments provide adaptability to thermal expansion and dynamic effects, allowing the system to simultaneously achieve both strength and adaptability

The vibration damping function is merged into the pipe structure itself through the flexible damper section with circumferential ridges, rather than adding separate external damping components. This integration reduces overall device complexity while still achieving effective vibration control

The flexible thin-walled cylindrical section with circumferential ridges acts as an inherent vibration damper, absorbing and dissipating vibrational energy through its flexible structure without requiring additional damping components, thus controlling vibrations while maintaining relatively simple construction
