Turbine/Propulsion Engine Cooling TRIZ Cases
- Turbine Blade Cooling via Bifurcating Wall and Coriolis Effect
Bifurcating internal wall directs cooling fluid radially upward along pressure side and downward along suction side to overcome centrifugal forces.
- Turbofan Heat Exchanger Hollow Vanes Airflow Regulation
Flow modulators in hollow vanes actively regulate cooling air to reduce aerodynamic penalties and improve engine performance.
- External Cooling Air Passage for Gas Turbine Rotor
External cooling air passages divert compressor air to turbine vanes and blades, reducing flow loss and structural complexity caused by internal rotor tubes.
- Hybrid Expander Cycle Gas Turbine with Pre-Compression Cooling
Pre-compression cooling reduces compressor discharge temperature, enabling higher pressure ratios and thermal efficiency in high-speed aircraft engines.
- Annular Cooling Flow Passage for Gas Turbine Thermal Management
Dual inlets feed an annular passage where internal walls guide airflow to coalesce, reducing thermal loading on high-pressure turbine components.
- Combined Cycle Plant Bypass Pipe for Reduced Start-Up Time
Bypass pipe warms steam lines concurrently, reducing start-up time while preventing water drop formation in cooling systems.
- Turbine Cooling Air Modulation via Flow Limiter Choking
Modulating cooling air flow through a choked flow limiter reduces compressor stage diversion, enhancing engine efficiency by minimizing energy loss.
- Swirler Tube Bracket Orientation Features for Gas Turbine Cooling
A swirler tube bracket uses asymmetric orientation tabs to direct cooling airflow into a gas turbine rotor cavity.
- Fuel-Cooled Cooling Air System for Gas Turbine Engines
A gas turbine engine uses fuel to cool compressor and turbine air via heat exchangers.
- Gas Turbine Cooling Circuit With Angled Plunged Holes
A gas turbine cooling circuit uses angled plunged holes intersecting a microcircuit to deliver internal convection and external film cooling.
- Hypersonic Power Module Fuel System Integration
Power module system merges auxiliary power unit with scramjet engine fuel supply to generate electrical and hydraulic energy.
- Turbine Cooling Diffuser Section for Heat Transfer Efficiency
A turbine cooling system uses diffuser sections to expand fluid before discharge onto component surfaces.
- Heat Transfer System for Turbofan Engine Ice Prevention
A heat transfer system uses waste gearbox energy to reduce ice buildup on turbofan engine components.
- Closed Gas Power System Electrolysis Recharge
An integrated thermal management system uses electrolysis to decompose waste coolant into reactants, sustaining operation without external fuel sources.
- Turbine Airfoil Cooling Structure with Impingement Insert
A turbine airfoil cooling structure uses a hollow cylindrical insert to direct impingement airflow against the internal surface for enhanced heat transfer.
