Blade Accessories TRIZ Cases
- Aerofoil Trailing-Edge Hinge for Shear-Resistant Control
A triangular flexible hinge moves the aerofoil trailing edge while resisting vertical shear, reducing buckling, vibration, and control force.
- CMC Turbine Blade Fuse for Predictable Overspeed Shedding
A root limiting section with 90-degree fibers enables controlled blade shedding during overspeed, limiting rotor speed and reducing disk weight.
- TiAl Rotor Blade Alloy Composition for Complex Casting Yield
A tailored TiAl alloy composition improves molten flow in investment casting while preserving impact, high-temperature, and oxidation resistance.
- Bladed Part Mould Assembly for Resin Injection and Shield Co-Moulding
A nested mould and wedge-clamped bell reduce resin leakage and enable metal shield co-moulding for composite turbomachine blades.
- Splittered Compressor Airfoils for Hub Flow Separation Control
Alternating full-height and reduced-height compressor airfoils limit hub flow separation while cutting rotor weight and preserving manufacturability.
- Ribbonized Ceramic Tows for Uniform Pore Distribution in CMC Fabrics
Flattening ceramic tows into ribbonized shapes evens pore distribution in CMC fabrics, improving matrix infiltration and interlaminar strength.
- Composite Environmental Barrier Coating With Dual-Zone Creep Control
A dual-zone rare-earth silicate coating limits surface creep while preserving inner stress relief to prevent cracking in ceramic matrix composite parts.
- Composite Turbomachine Vane Weaving for Crack-Resistant Attachment Lugs
3D woven vane preforms integrate lugs and platforms to align fiber loads, reduce stress concentration, and prevent cracks at attachment points.
