Description

Landing gears are intended for static and dynamic loads transmission on AN-140 aircraft structural elements during parking, landing, takeoff, running and aircraft taxiing.

 

The design of the landing gears allows to operate the aircraft both on concrete and dirt runways with the soil strength not lower than 6 kgf/cm2 under all weather conditions.

 

The landing gears are manufactured according to the technical documentation of Antonov company, corrected according to the results of certification tests and approved by the Decision AN-140-005-00 dated 11.12.2000  on the basis of the interdepartmental commission act dated 11.12.2000.

 

Nose landing gear for AN–140

 

The front stanchion is a strut with two non-brake wheels.

 

The fuselage carries the nose landing gear towards to flight direction and is closed by large and small doors.

 

The landing gear elements:

  • shock;
  • rack-and-pinion type steering gears;
  • unit and lever with the axis of the wheels.

 

Main landing gears for AN–140

 

The main landing gear consists of:

  • traverse;
  • shock;
  • lever with the axis of the wheels.

 

All components are connected together pivotally and form a closed structure.

 

Main landing gear strut for AN-140

 

The strut is a compression system of units that react a land reaction and fasten main landing gear to the fuselage.

Key components:

  • lower strut;
  • upper strut;
  • fasteners.

 

Supplied with the main landing gear.
