Turbines TRIZ Cases

Laser-clad epitaxial MCrAlY and abrasive layers protect single-crystal blade tips from wear and oxidation while reducing leakage losses.

Radial bore holes and threaded pins repair cracked wind turbine blade roots, stop crack growth, and avoid full blade replacement.

Laser-etched hydrophilic patterns guide condensed moisture toward extraction openings, reducing steam turbine erosion and aerodynamic loss.

Rounded joint contours between outer walls and intermediate pieces cut stress concentration and inner-cavity vortices in turbomachine components.

A low-energy beam sinters a skull layer before melting, reducing powder-bed turbulence, powder loss, and porosity in metal additive manufacturing.

FAST joins cast turbine blade sections under load and current to bond different alloys while limiting thermal expansion mismatch.

Hot shot peening between deposited metal layers relieves residual stress, removes oxides, and improves microstructure uniformity.

Discrete metal portions create conductive bridges in high-viscosity sealants and adhesives, improving resistance weldability without losing strength.

Pre-sintered support structures and low-melt braze form repairable cooling channels in gas turbine hot-section components.

Repairs internal gas turbine defects through access ports using liquid metal or powder filler, avoiding engine removal and cutting downtime.

Annular support members reinforce reduced cross-sections during inertia welding to balance loads and prevent weld stress, distortion, and rupture.

A shaft-driven gear pump keeps the wind turbine main bearing lubricated during operation, avoiding electric power loss shutdowns.

Preplaced braze fills heat-treatment cracks in additively manufactured nickel superalloy parts, preserving turbine component integrity and cutting repair steps.

Detachable workpiece support, NC feed, and laser-based position sensing help robot drilling cut vibration and improve borehole accuracy.

Single-cavity impulse body modules cut gas turbine blade detuning complexity while maintaining impact-based vibration reduction.

Separate cooling and lubrication ducts route oil around a turbomachine bearing to lower temperature while avoiding excess flow and energy loss.

Adjusting sweep length to match faying-length differences spreads frictional heat evenly, preventing cold corners and edge detachment.

A set-back flat support on additively manufactured turbine blade preforms keeps polishing off the leading or trailing edge, reducing defects and rework.

Chemical analysis of filtered engine lubricating fluid quantifies volcanic ash contamination to predict wear and guide maintenance.

A seed crystal in electron beam melting controls superalloy microstructure for complex shapes while improving ductility and creep resistance.

Narrow-gap welded high-strength rings reinforce corrosion-stressed blade slot regions while avoiding full-shaft use of costly materials.

Scalloped flange openings align weld beads with hollow portions, cutting electron beam penetration layers to improve exhaust casing weld stability and quality.

A widening annular flow path spins turbine oil to collect debris before the main filter, cutting particulate load and maintenance.

Shrouds define blade tip cladding edges during laser deposition, cutting post-machining while preserving thermal loading resistance.
