Stators TRIZ Cases
- VTOL Stator Stabilization for Rotor Alignment and Low Noise
Active stator field control and damping components keep rotor alignment stable in VTOL maglev flight while reducing noise and inefficiency.
- Die-Cast Aluminum Alloy Composition for Strength and Conductivity
A nickel-iron-titanium aluminum alloy balances yield strength, electrical conductivity, flowability, and hot-tear resistance in die casting.
- Turbine Vane Ring Assembly Using Heated Outer Ring and Radial Jaws
Heating the outer ring and using radial jaws plus axial pressing speeds turbine vane ring assembly while reducing damage risk.
- Vane Ring Assembly Tooling Using Heat Expansion and Press Fit
Heating the outer ring and using expandable jaws plus a press speeds vane ring assembly while reducing damage to press-fitted turbine parts.
- Bladed Stator Welding Tool for Flange Retraction Compensation
A tensile preloading tool elastically offsets weld-induced flange retraction in bladed stators, reducing post-weld machining and vane replacement issues.
- Metal Repair Preform for Brittle CMC Defect Replacement
A metal repair preform replaces damaged CMC sections to cut repair cost and reduce brittle failure in turbine engine components.
- Roll-Welded Cooling Channels for Cast Motor and Battery Housings
Roll-welded sheet channels enable branched cooling paths in cast motor and battery housings while avoiding welding deformation.
- Variable-Pitch Turbine Stator Sector for Passage Section Homogeneity
Variable-pitch stator blades correct sector misalignment to homogenize turbine passage sections and improve turbomachine efficiency over engine life.
- Twin-Scroll Turbine Tongue Layout for Lower Blade Vibration
Different tongue-to-impeller radial distances in a twin-scroll turbine cut excitation force and blade vibration without sacrificing aerodynamic performance.
- Single-Piece Turbomachine Splitter for Low-Loss Deicing
An integrated annular baffle guides hot air to the splitter, cutting heat loss and deicing demand without hurting turbomachine performance.
- Turbine Exhaust Flange Structure for Thermal Stress Relief
A multi-material exhaust flange with ring and tubular sections accommodates thermal expansion and lowers stress at the strut junction.
- Guide Vane Segment Support Ribs to Prevent Machining Cracks
Radial support ribs stiffen gas turbine guide vane support sections, improving force distribution and reducing machining cracks.
- Stator Blade Pitch Variation for Turbine Rotor Pressure Distortion
Non-uniform stator blade pitch matches circumferential pressure distortion to balance rotor flow and reduce stability margin loss.
- Turbine Scroll Assembly for Uniform Axial Turbine Inlet Flow
Scroll stator vanes and an annular collection region smooth rotary-engine exhaust pulsation for more uniform turbine inlet flow and lower stress.
- Low-Pressure Nozzle Ring Clamping Pads for Wear and Corrosion
Replaceable pads between the nozzle ring root and clamp absorb friction and contact corrosion, cutting turbine maintenance cost and downtime.
- Multi-Material Turbine Exhaust Flange for Thermal Deflection
A segmented outer flange in a different material absorbs turbine case thermal deflection and lowers stress concentrations during transients.
- Turbine Scroll Vane Passages for Uniform Inward Gas Flow
Vane passages steer combustion gas inward and tangentially, reducing flow pulsations and nonuniformity at the axial turbine inlet.
- Segmented Variable Outlet Guide Vanes for Fan Incidence Control
Independent tip and hub vane segments adjust fan exit flow to improve operability, stall margin, and incidence control.
- Gas Turbine Bearing Strut Relief Feature for Damage-Free Removal
A machined relief feature creates a collapse path, removing an interference-fit strut without damaging the bearing structure.
- Lightweight Gas Turbine Tierod Assembly for Bearing Compartment Space
Matched nickel-alloy expansion and brazing join the tierod to the bearing ring while enlarging space for cooling and oil routing.
- Single-Piece Gas Turbine Vane Array with Deformable Baffles
Additive manufacturing integrates vanes, mounts, and deformable baffles to simplify assembly and reduce gas turbine engine mass.
