Efficient Propulsion Technologies TRIZ Cases
- Translating Cowl Thrust Reverser Efflux Management
A translating cowl thrust reverser system uses segmented turning vanes to redirect exhaust airflow vertically away from the aircraft fuselage.
- Stepped Acoustic Structure for Multi-Degree Impedance Control
A stepped acoustic structure anchors septum caps at uniform depth while varying cell cross-sectional area to tune acoustic impedance.
- Wing Fold Latch Pin Cam Mechanism for Airport Infrastructure
Interdependent latch pins and cams constrain wing movement to enable folding transitions between flight and ground configurations.
- Airfoil Module Segmentation for Thermal Stress Relief
Segmented airfoil modules accommodate thermal expansion via movable ring assemblies, reducing stress and strain on turbine components.
- Thermal Blanket Transparent Window for Gas Turbine Inspection
A thermal blanket integrates a fused silica glass window into its non-transparent portion to shield engine components from heat.
- Turbofan Thrust Reverser With Segmented Cowl And Vane Arrangement
A turbofan thrust reverser uses a segmented cowl and vane arrangement to redirect airflow for reverse thrust.
- Turbofan Fan Case Supports for Thrust Reversal Weight Reduction
Shoes and skirts on the fan case exterior wall support mobile thrust reversal sliders, reducing structural weight while maintaining rear edge stability.
- Aircraft Engine Anti-Icing Barrier Assembly Slip Joint
Welding supply ducts to the engine inlet eliminates high-temperature seals, reducing assembly weight and maintenance time for aircraft engines.
- Multi-Stream Nozzle Supersonic Ejector Thrust Control
A multi-stream nozzle merges a third bypass stream with the primary exhaust flow using a supersonic ejector to adjust effective area ratios.
- Electric Torque Arm Helicopter Autorotation Safety Landing
Coaxial motor alignment eliminates tail rotor complexity while torque arm propellers hinge open for safe autorotation.
- Mixer Duct Shell Acoustic Lining for Turbofan Exhaust Noise
A mixer duct shell with a honeycomb core structure absorbs sound waves and dissipates heat from fan exhaust gases, reducing community disturbance.
- Hybrid Rocket Thruster Motor Fuel System
External fluid fuel storage reduces onboard volume, increasing payload capacity while maintaining sustained thrust.
- Mid-Turbine Frame Thermal Radiation Shield Design
A thermal radiation shield blocks line of sight between hot and cold fluid flow paths in gas turbine engines.
- CMC Shroud Support System Load Spreading Design
Shroud support system with load spreading reduces stress concentrations in ceramic matrix composite segments.
