Continuous Combustion Chamber TRIZ Cases
- Dome-Deflector Joint Cooling for Gas Turbine Bolt Head Protection
Cooling air routed from the dome-deflector cavity protects gas turbine bolt heads from combustion heat, extending bolt life and reducing replacements.
- Combustor Tile Retention Using a Thermally Shielded Fastener Compartment
A heatshielded compartment isolates combustor tile fasteners from combustion heat, extending retention life and reducing assembly complexity.
- Self-Pressurized Ammonia Fuel Supply for Stable Turbine Combustion
Heating liquid ammonia in the supply tank builds vapor pressure to feed a gas turbine combustor without pumps, reducing bubbles and cost.
- Multi-Circuit Fuel Injector for Gas Turbine Power Tuning
Three discrete fuel circuits tune atomization and distribution across power settings to improve combustion and cut NOx, smoke, and tones.
- Ceramic Matrix Composite Interface Coating for Oxidation Resistance
Multi-layer carbon and boron nitride fiber coatings block oxidant ingress and crack growth in high-temperature ceramic matrix composites.
- Hydrogen Gas Turbine Combustor Sizing for Low-NOx Combustion
Combustor sizing rules cut hydrogen residence time and improve fuel-air mixing to lower NOx while maintaining stable gas turbine combustion.
- Retractable Fuel Injector for High-Altitude Fuel Atomization
A retractable valve body varies injector orifices to raise delta pressure, improving ignition, atomization, and smoke control at altitude.
- Hydrogen Injector Fairing and Annular Passage for Uniform Mixing
A fairing-defined annular passage in a convergent-divergent injector improves hydrogen-air mixing and helps prevent flame propagation in gas turbines.
- Gas Turbine Fuel Circuit Zoning for Safe Alternative-Fuel Start
Separate start and main fuel circuits stage injection by combustor zone to keep startup mixtures below flammability limits and reduce deflagration risk.
- Cryogenic Fuel Startup Heating for Low-Energy Engine Vaporization
A two-stage startup sequence preheats part of the cryogenic fuel, then amplifies heating to vaporize the main flow with lower start energy.
- Hydrogen Turbine Combustor Size Rating for NOx Residence Time
A combustor size rating linked to core airflow cuts hydrogen flame residence time to meet NOx targets without added diluents.
- Cooling Panel Segment With Integrated Distribution Channels
Integrated circumferential channels replace separate pipes in turbomachine casing cooling, cutting parts, assembly effort, and stress.
- Hydrogen Fuel Conditioning for Air-Breathing Engines Without Chamber Heat
Pressurized liquid hydrogen is heated and partially combusted to create oxygen-free fuel gas without using combustion chamber heat.
- Cryogenic Fuel Startup Using Two-Stage Thermal Vaporization
A two-stage thermal sequence vaporizes cryogenic fuel for gas turbine start-up, reducing external heating demand before engine heat recovery begins.
- High-Shear Fuel Injector Swirler for Stable Gas Turbine Mixing
A multi-segment high-shear swirler thins the fuel film to improve gas turbine mixing and reduce combustor dynamics and tones.
- Steam Ejector Injector for Turbine Combustion Flow Modulation
Steam flow through an injector modulates fuel and compressed-air delivery in a turbine combustor, improving combustion efficiency with hydrogen-capable operation.
