Energy Efficient Operational Measures TRIZ Cases
- Preconditioned air unit with variable frequency driving
See how variable frequency drivers adjust compressor capacity in ground-based aircraft cooling
- Aircraft Landing Gear In-Wheel Motor for Fuel-Efficient Taxiing
An in-wheel stator-rotor landing gear drives aircraft taxiing and regenerative braking to cut fuel use, towing loads, and airport dependence.
- Landing Gear Brake Cooling With Brushless DC Fan Drive
Brushless DC fan cooling cuts landing gear brake heat without heavy AC overspeed protection, improving aircraft turnaround.
- Aircraft Wheel Motor With Concentric Rings for Landing Gear Retrofit
A concentric stator-rotor wheel motor fits existing landing gear axles, enabling electric taxiing without major structural changes.
- Compact Biwheel Suspension and Torque Control Against Gerbiling
Leaf-spring wheel support, in-wheel electric drive, and attitude control curb biwheel gerbiling while preserving cockpit access and ride comfort.
- Aircraft Brake Pressure Control for Single-Engine Taxi Yaw
Automatic brake pressure scaling counters single-engine taxi yaw, helping aircraft hold a straight path with less pilot input and fuel burn.
- Passive Maglev Guide Assembly for Lateral Stability Across Speeds
Spring-biased wheels and magnetic repulsion keep a maglev vehicle centered against guide walls from low to high speeds without active control.
