landing_gear_imageDue to it´s higher maximum take-off weight the F-15E features an strengthened landing gear system.

This tricicle-type landing gear system consists of one nose landing gear unit and two main landing gear units with Bendix wheels and Michelin AIR-X radial tires. The size of the nose landing gear tire is 22x7.75-9 while the size of the two main landing gear tires is 36x11-18. The bigger size of the main landing gear wheels and tires (compared to those of previous F-15 variants) necessitated a noticable outward bulge in the main landing gear doors. Tire pressure is 21 bar (305 psi) for all three tires.

All units are equipped with oleo-pneumatic shock absorbers by Cleveland Pneumatic Tool Company. Landing gear assemblies and bays are painted FS17875 Gloss White.

Nose Landing Gear

The nose landing gear ( NLG) hydraulically retracts forward into a wheel well under the cockpit and provides a steering system which is automatically activated when the wheel is on the ground. During taxing the steering system allowes 15 degrees of turn while 45 degrees are possible to maneuver the aircraft on the ramp.

The NLG incorporates a small taxi light, which is mounted on the actuator strut, above the larger landing light, and has two gear doors. The larger forward gear door is operated hydraulically and opens only during extension and retraction. On the ground it can be opened manually for servicing. The smaller aft door is linked to the NLG´s leg. It is pushed open when the gear is lowered and pulled into it´s closed position when the gear is retracted.

Main Landing Gear

The main landing gear ( MLG) also retracts forward, fullfilling a 90 degrees turn to lie flat in the wheel wells. They are equipped with carbon heat-sink type brakes by Bendix and an anti-skid system by Hydro-Aire. The brake system features an emergency system that provides hydraulic accumulator pressure to power the brakes in case of a malfunction or loss of the normal hydraulic system. When the emergency system is active the anti-skid system is not available.

Each MLG has three doors. The two forward doors are operated hydraulically and open only during extension and retraction but can be opened manually for maintenance works on the ground. The aft door is mechanically linked to the strut and remains open when the MLG is extended.
