Propellers TRIZ Cases
- Rotor Blade Actuator Lubrication System Design
A rotor blade actuator uses a tip-mounted sump and pump to deliver lubricant to the bearing.
- Anodized Aluminum Propeller Coating Abrasion Resistance
Hard anodized aluminum oxide layers protect propeller blades from chipping and plastic deformation in abrasive sandy waters.
- Rotating Filament Insect Repeller for 360-Degree Air Disruption
A portable apparatus uses a rotating filament to generate dynamic air disturbances that disrupt insect flight patterns.
- Propeller Pitch Control via Onboard Electrical Generation
Onboard electrical generation eliminates complex hydraulic systems for propeller pitch control, reducing maintenance needs and system weight.
- Radial Shaft Pitch Control for Unducted Fan Hub Ratio Reduction
External mounting of a common radial control shaft reduces hub ratio constraints, enabling smaller hubs and lower fuel consumption in unducted fan engines.
- Propulsor Hub Weight Balance Using Tungsten Rings
Tungsten balance rings attach to propulsor hub rims to counteract rotational forces, reducing rotor assembly weight while maintaining stability.
- Turbine Airfoil Cooling Apertures via Segmented Aperture Panel
Segmented aperture panel enables efficient manufacturing of complex cooling patterns without drilling through the airfoil structure.
- Inflight Propeller Balancing via Accelerometer Vibration Filtering
Accelerometers capture propeller vibration during flight, filtering data to detect imbalance trends and trigger maintenance alerts.
