Engine Manufacture TRIZ Cases
- Co-bonded Acoustic Liner with Thermoset Septa Film
A co-bonded acoustic liner uses a thermoset plastic septa film to dampen sound while maintaining structural integrity.
- Modular Winding Core for Variable Rotor Blade Ends
Interchangeable winding core sections vary longitudinal extent and diameter, reducing production costs for variable rotor blades.
- Angled Core Gas Turbine Engine Mounting for Aircraft Survivability
Angled core gas turbine engines mount propulsors at skew angles to prevent fragmentation interference between adjacent units.
- Wind Turbine Pitch Motor Relocation Bracket
A replacement motor mount displaces a wind turbine pitch motor to avoid damaged bearing regions, enabling in-situ repairs without removing the rotor.
- Turbine Diaphragm Mechanical Interference Fit Assembly
Mechanical interference fits join turbine diaphragm components, eliminating welding defects and reducing manufacturing costs.
- Scalloped Turbine Platforms Reducing Vortex Pressure Losses
Scalloped turbine platforms with bulges and bowls redirect flow to reduce secondary vortex strength, lowering pressure losses at blade junctions.
- Turbomachine Nozzle Vane Angular Positioning for Thermal Uniformity
Synchronized nozzle vane angular positioning aligns injector heads with dilution air holes to maintain uniform thermal exposure across the turbine outlet.
- Volute Casing Stiffening Elements for Hydraulic Machine Stress Reduction
Inwardly bent stiffening elements reinforce hydraulic machine volute casing segments to distribute mechanical stress peaks at transition points.
