Turbines TRIZ Cases
- Combustor Inspection Port for Sacrificial Support Verification
An engine casing inspection port enables direct viewing of sacrificial combustor supports, reducing disassembly effort and assembly checks.
- Low-Carbon René 77 Powder for High-Temperature Creep Resistance
Controlling René 77 powder carbon to 200 ppm or less enables grain growth during heat treatment and extends creep life above 800°C.
- Hollow-Blade Turbomolecular Rotor for High-Temperature Vacuum Pumping
Hollow rotor blades and high-density alloys raise turbomolecular pump temperature and pumping rate without increasing pump volume.
- Segmented Rotor Protection Casing for Transport Damage Prevention
Spring-biased segmented casing secures thin-vane gas turbine rotors during transport and handling, reducing deformation risk before post-processing.
- Gas Turbine Cooling Segment With Helical Twist Flow Paths
Helical intersecting flow paths increase heat exchange area in a gas turbine cooling segment without sacrificing structural rigidity.
- Locking Cavity Plug for Clean Additive Part Removal
A locking cavity plug seals internal openings before build-plate removal, blocking debris entry and reducing post-processing.
- Partial-Shroud Impeller Structure for Blade Rub Control
A partial shroud integrated with full and splitter blades limits casing rub while preserving compressor performance and reducing weight.
- Thin Titanium Porous Sheet Debinding for Compression and Permeability
Inverted debinding removes binder before sintering, helping thin titanium porous sheets resist compression without wrinkles that block flow.
- Hybrid Alloy Isogrid Engine Case for Thermal Expansion Control
Dissimilar-alloy hollow ribs on a titanium wall control thermal expansion, reduce stress concentrations, and maintain engine case clearance.
- Turbine Engine Wall Cooling Apertures via Zoned AM Energy Control
Zoned energy input in powder-bed additive manufacturing improves small turbine wall cooling aperture uniformity and reduces defects.
- Distortion Mitigation Structure for Hybrid AM Boss Deposition
Radiating heat-dissipation structures let hybrid LPBF and DED build larger bosses on thin walls with less distortion and fewer build failures.
- Flexible Electrode Electropolishing for Complex Internal Passageways
A shuttle-guided flexible electrode electropolishes rough internal passageways, improving finish uniformity and reducing electrolyte stagnation.
- Branched Rotor Support Structure for Lightweight Air Compressors
A branched additively manufactured rotor support cuts weight while improving stress distribution, compressor efficiency, and rotor life.
- Annular Bearing Chamber Oil Distributor Without Separate Nozzles
An integrated annular manifold and strut flow channels replace fastened nozzles, reducing part count while preserving bearing chamber lubrication and cooling.
- Curved Acoustic Liner Honeycomb Forming From Flat AM Cores
Flat-printed honeycomb cores use corrugated wall edges and heated mold forming to create curved acoustic liners with less support material and smoother surfaces.
