Energy Efficient Operational Measures TRIZ Cases
- Aircraft Onboard Electric Drive Motor for Ramp Safety
An onboard electric drive motor powers aircraft wheels for ground movement without main engines, eliminating jet blast hazards and reducing turnaround time.
- Parallel Aircraft Parking with Electric Taxi Drive
Electric taxi drive systems enable automated parallel aircraft parking, eliminating jet blast risks and optimizing terminal space usage.
- Aircraft Autonomous Movement Power System with Parallel Generators
Segmented parallel generators handle autonomous movement needs and recover wheel energy to assist the auxiliary power unit, eliminating heavy storage mass.
- Aircraft Motor Phase Short-Circuiting for Electromotive Force Protection
Short-circuiting electric motor phases during deactivation prevents electromotive force generation.
- Motorized Wheel Suspension Clutch for Shock Isolation
Segmenting the motor block on the suspension strut isolates landing shocks, while a clutch device protects transmission efficiency.
- Aircraft Landing Gear Drive System with Pivotable Pinion
An electric motor drives a pivotable pinion that meshes with a wheel gear, enabling ground taxiing and pre-spinning without engine thrust.
- Aircraft Steering System Using Regenerative Braking Energy
Aircraft steering system recovers braking energy to power motor-generators, eliminating redundant storage devices and reducing fuel consumption.
- Aircraft Undercarriage Telescopic Shaft and Differential Drive
Nesting the telescopic shaft and differential inside the undercarriage protects transmission components from external stone impacts and brake dust.
- Mobile Aircraft Maneuvering Platform with Adaptive Coupling
An adaptive coupling mechanism connects a moving platform to aircraft landing gear, resolving adaptability versus complexity trade-offs.
- Double-Star Motor Landing Gear Actuator Redundancy
Independent control channels in a double-star motor actuator enable safe gravity deployment braking while reducing weight.
- Epicyclic Gearbox External Annulus Input
An epicyclic gearbox uses an external annular gear to transfer power directly to internal sun gears.
- Aircraft Landing Gear Wheel Rim Segmented Ring Gear Design
Segmented blocks on the wheel rim form a lightweight ring gear that engages the drive actuator while accommodating rim deformation under load.
- Aircraft Wheel Rotation Drive Mechanism
Movable rollers transmit torque to aircraft wheels, eliminating permanent meshing safety risks.
- Aircraft Drive Wheel Traction Recovery via Steering and Braking
Coordinated steering and braking apply differential force to release stuck aircraft tires from runway adhesion without increasing wheel size.

Segmented elastic arms accommodate axle deformations to maintain optimal torque transmission without increasing aircraft weight or maintenance complexity.
- Aircraft Self-Propelled Drive Wheel Ground Maneuvering
An electric motor system drives aircraft wheels independently, reducing turnaround time and eliminating jet blast hazards during ramp operations.
- Aircraft Landing Gear Drive System Torque Vibration Control
Compensating gears counteract torque oscillations in aircraft landing gear drives, reducing fuel consumption and brake wear during ground taxiing.
