Engine Manufacture TRIZ Cases
- Segmented Wind Turbine Rotor Blade Dovetail Joint Assembly
A dovetail joint assembly secures segmented wind turbine rotor blades, reducing manufacturing complexity and easing field assembly without specialized equipment.
- Geometrically Segmented Thermal-Insulation Coating Against Spallation
Surface features create through-coating faults that dissipate thermal stress, improving strain tolerance and limiting topcoat spallation.
- Thrust Reverser Inner-Wall Cooling With Isogrid Air Channels
An isogrid panel, air plenum, and vented airflow path cool a thrust reverser inner wall to limit heat exposure and thermal degradation.
- Wind Turbine Blade Spar Cap Bonding With Heat-Activated Silane Primer
Moisture-reactive primers and grinding can limit wind turbine blade bonding; heat-activated silane treatment improves spar cap adhesion during resin co-infusion.
- Aircraft Turbomachine Flow Guide for Low-Loss Heat Recovery
A downstream flow guide redirects turbine exhaust radially to the heat exchanger, reducing thermal and pressure losses during steam generation.
- Aircraft Heat Exchanger Curved-Tube Layout for Stress Relief
Curved tube paths and downstream-offset manifold locations accommodate thermal expansion and aerodynamic loads, reducing stress and strain.
- Thrust Reverser Inner-Wall Cooling With an Integrated Air Plenum
An air plenum between the isogrid panel and inner heat shield uses vented cool air to protect the thrust reverser inner wall from thermal degradation.
- Geometrically Segmented Insulating Topcoat for Spallation Control
Vertical faults let the insulating topcoat accommodate thermal expansion, dissipate stress, and resist spallation in engine service.
- Variable-Geometry Aircraft Air Inlet With Rack-and-Pinion Actuation
A rack-and-pinion drive translates the movable upstream portion of an aircraft propulsion air inlet, reducing actuator size and synchronization complexity.
- Wind Turbine Blade Leading Edge Repair With UAV Robotics
A hovering UAV moves a robotic maintenance device onto the blade, enabling precise leading-edge repairs while the turbine stays assembled.
- CMC Airfoil Cavity Ply Thickening for Stress Management
A localized pressure-side ply thickening reinforces a gas-turbine CMC airfoil where stress is highest while limiting excess material.
- Gas Turbine Thrust Reverser Nozzle With Oval Flow Area
An oval cross-section expands thrust reverser flow area within limited nozzle length while preserving circular inlet and exit sections.
- Airfoil Serpentine Cooling Passages for Turbine Blade Heat Dissipation
Serpentine passages extend cooling-fluid paths through the airfoil, increasing heat absorption time for high-temperature turbine blades.
- CMC Blade Outer Air Seal Assembly for Thermal Stress Control
A segmented CMC seal uses wedge seals and spring clips to manage thermal gradients while maintaining blade-tip sealing integrity.
- Wind Turbine Tower Bolt Lifting Aid for Ergonomic Assembly
Bolts weighing over 15 kg are handled with a mast, lifting shoe, and actuator that support ergonomic wind turbine tower assembly.
- Wind Turbine Blade With Multiple Spar Caps for Fibre Alignment
Separate spar caps and a variable-width recess help align fibre-reinforced layers and reduce defects in large wind turbine blades.
- Axial-Cavity-Free Pen-Type Bushing Securing for Wind Blades
Axial-cavity methods do not fit pen-type bushings; rod-guided compound flow and sealing protect threads during blade-root replacement.
