Undercarriages TRIZ Cases
- Adjustable Nose Landing Gear for Low-Speed Takeoff
An adjustable nose landing gear reduces takeoff speed by hiking the shock strut, then automatically de-hikes to minimize stowage space and landing forces.
- Landing Gear Actuator Sequence to Eliminate Force Fight
Sequential hydraulic pressure application releases the uplock before deploying the landing gear, eliminating force fight and loud thump during deployment.
- Aircraft Landing Gear Breaker Strut with Adjustable Hinges
Adjustable breaker strut hinges and phase-shifted dual slider-crank mechanisms reduce retraction torque while minimizing landing gear compartment volume.
- Aircraft Landing Gear Cavity Baffles for Drag Reduction
Vertical baffles and a curved aft fairing guide airflow through exposed landing gear cavities, reducing drag by 56% compared to previous designs.
- Aircraft Landing Gear Bracing Lock Lever Mechanism
Curved slot geometry constrains spring extension, reducing stress and extending lifespan.
- Landing Gear Bay Door Roller Slot Mechanism
A roller slot mechanism controls aircraft landing gear bay doors through a drive rod and crank assembly.
- Fuselage Landing Gear Retracting via Four-Bar Linkage
A fuselage-mounted landing gear system moves the wheel assembly between deployed and stowed positions using a pivoting trunnion brace.
- Aircraft Landing Gear Gravity Deployment Linkage
Dynamic retraction linkage enables rapid gravity-driven landing gear deployment, reducing aero-acoustic noise duration during approach.
