Propellers TRIZ Cases

Woven internal airflow channels in composite propeller blades redirect slipstream from root to trailing edge, mitigating intake distortion and pressure drop.

Cross-connecting clutch engages dual hybrid propulsion systems to drive propellers and manage torque distribution.

Segmented sensors and preliminary trajectory calculations enable safe propeller parking control during electric aircraft transitions.

A trunconical bellows with an O-ring seals connecting rods in rotating oil chambers.

Asymmetric fastback turbulators prevent flow stagnation and dust accumulation in gas turbine engines while maintaining high heat transfer efficiency.

Internal ribs in the tip shroud cavity distribute coolant flow, lowering metal temperatures and mechanical stress on the structure.

A spring-loaded lock pin engages a rotating aperture to secure ram air turbine blades during stowage.

A hybrid-electric engine adjusts the rotational force ratio between electric and thermal components to reduce noise during takeoff.

Acoustic sensors detect tonal noise emissions in wind turbines to trigger control units that adjust operating parameters.

Rotating leading edge structure shifts foil contour via sliding skin edges, reducing mechanical complexity and drag forces compared to traditional flaps.

Feedback swashplate assembly adjusts blade pitch via linear actuators to resolve stability and complexity trade-offs during flight mode transitions.

Rim-mounted airfoil blades create an airflow gap that reduces rotational resistance and minimizes bird collision risks.
