Text 1.Landing Gear

The landing gear or undercarriage is one of the main structural units of the аіrplane. The landing gear provides support for the аіrplane during static and ground manoeuvring conditions. Structurally it reacts to the аіrplane loads in three axes and the component forces that are generated during its motion.

The landing gear usually consists of the main and auxiliary units. The main landing gear is attached near the center of gravity of an аіrplane and forms its principle support. The auxiliary landing gear forms an auxiliary support and as it is far away from the center of gravity of the machine and less loaded it is made comparatively light.

Present day airplanes have a tricycle type landing gear consisting of two main gears and a nose gear. This design has some advantages, namely: it improves visibility during taxiing, reduces the possibility of hose over, makes an аіrplane more stable during landing as the center of gravity is ahead of the main wheels.

Аіфіапе5 having a tricycle type landing gear employ air/oil shock stints Hydraulic power is used for normal gear extension and retraction. In a large number of airplanes the gear may be extended manually. Shock strut compression is used for air/ground sensing control and utilizes solid state sensors as does (he indication and warning system. Nose wheel steering is available for taxing and takeoff and for directional control when the аіrplane is on the ground. A steering wheel gives up to about 78 degrees left and right steering capability.

Brakes are installed on the main gear and may be operated in either manual or automatic mode; an antiskid system is used to increase braking effectiveness.

Landing gear control and indication components include: the landing gear selector lever and indication lights, manual extension handles, parking brake lever and indicator, nose gear steering control wheel, antiskid control switch and inoperative indicator, and the autobrake control switch and disarm indicator.
