KT135A / KT135A.000

Installation of KT135A on main landing gear

The KT135A wheel assembly is installed on the main landing gear struts. In the Mi-24 / Mi-35 landing gear context, the assembly is used on the left and right main struts, not on the nose landing gear. The unit carries static load while the aircraft is parked and absorbs dynamic loads during touchdown, landing rollout and taxiing. Applicability should be confirmed through the aircraft parts catalogue, landing gear documentation and wheel-brake assembly records before supply or installation.

KT135A.010 wheel body in the assembly

The wheel section of the assembly is KT135A.010. It is a split-rim magnesium wheel body designed for a 720 × 320 mm tube-type aircraft tire, with 15A / 15AM tire models referenced in the source context. The wheel has internal splines / grooves that engage with the rotating brake discs. The split construction allows tire and tube replacement during maintenance. The wheel section may be requested separately from the complete KT135A.000 assembly, so the exact supply scope should be clarified before ordering.

KT135A-030 pneumatic brake block

The brake section of the KT135A assembly is KT135A-030. It is a pneumatic disc brake actuated by compressed air from the aircraft onboard system. When air pressure is supplied to the brake block, the pistons compress the friction disc pack and produce braking torque. The brake provides deceleration after landing, assists ground maneuvering and holds the aircraft in place during parking or engine run-up. Its operation depends on correct air pressure, sealing condition, disc condition and proper installation inside the wheel.

Ground control and parking function

KT135A supports both braking and ground maneuvering. On helicopters, differential braking of the left and right main wheels can assist turning and ground control during taxiing. The brake also provides parking hold, keeping the aircraft stationary during ground operations, including engine start and testing. Because the assembly combines the wheel, tire, pneumatic brake and friction disc pack, inspection should include the wheel rim, bolts, tire and tube, bearings, brake discs, pneumatic seals and related hardware.

Identification and ordering of KT135A

Before ordering KT135A / KT135A.000, it is important to confirm whether the requirement is for the complete wheel with brake, the KT135A.010 wheel only, the KT135A-030 brake only, or additional tire and tube equipment. Related items may include 720 × 320 aircraft tires, inner tubes, valves, KT135.050 rotating brake discs, stationary brake discs, pressure / support disc, fasteners, bearings and rubber technical parts. Documentation requirements, condition category, passport availability and quantity should be agreed before shipment.
