Landing Gear Retraction System

Hydraulic or electric actuators that extend and retract the main and nose gear assemblies, with uplocks, downlocks, and emergency free-fall backup.

Multi-disk carbon or steel brakes on main gear wheels, applying friction through hydraulic or electro-hydrostatic actuators.

Electronic system that modulates brake pressure to each wheel independently, preventing tire lockup on wet/contaminated runways.

Hydraulic system providing directional control during taxi via tiller or rudder pedal input.

High-pressure tubeless tires (200+ psi) mounted on forged aluminum or magnesium wheels.

Telescoping strut using compressed nitrogen and hydraulic oil to absorb landing impact energy.

Proximity switch on landing gear strut detecting ground/air transition, arming/disarming critical systems.

Pre-selected automatic braking that activates on touchdown based on deceleration rate setting (LOW/MED/HIGH/MAX).

Full-span spoiler panels that deploy automatically on touchdown to dump wing lift and transfer weight to wheels.

Nose gear towing attachment point, bypass pin provisions, and steering disconnect for ground handling.
