KT159-030 / KT159.030-1 nose aircraft disc brake

KT159-030, also written as KT159.030-1, is an aircraft nose disc brake used on the Il-76 front landing gear wheel-brake system. The brake is installed in the KT159-010 nose wheel assembly when the aircraft configuration includes braking of the nose landing gear. The unit assists the main wheel brakes during landing rollout and ground operation, helping reduce aircraft stopping distance under demanding operating conditions. It is a hydraulic multi-disc brake and works as part of the aircraft landing gear and braking system.

Function of KT159-030 on the Il-76 nose landing gear

The KT159-030 brake is intended to provide additional braking force through the nose landing gear. In normal aircraft braking, the main braking load is carried by the main wheel brakes, but the nose brake can assist in reducing the landing rollout distance and improving braking efficiency. This is especially relevant in source context for shortened landing or operation on unpaved / field airfields. The brake must be considered together with the nose wheel, hydraulic system, brake control logic and aircraft configuration.

Installation with KT159-010 nose wheels

KT159-030 is associated with the KT159-010 nose wheel used on the front landing gear of Il-76 aircraft. The brake is installed inside the nose wheel assembly where the corresponding modification provides for nose wheel braking. Since KT159-010 may also be described as a nose, generally non-braked wheel in some contexts, the actual requirement should be checked carefully. Before supply, it is important to confirm whether the customer needs the brake assembly, wheel only, wheel with tire, or a complete nose wheel-brake set.

Multi-disc hydraulic design of KT159-030

KT159-030 is a compact multi-disc hydraulic aircraft brake. Its design is similar in principle to the main wheel brakes but smaller, corresponding to the nose wheel and tire size. During braking, hydraulic pressure acts on the cylinder block pistons and compresses the brake disc pack. The friction between rotating and stationary discs produces braking torque. The brake operates with aviation hydraulic fluid and must be inspected for disc wear, piston condition, seal condition, hydraulic leakage and correct installation inside the wheel assembly.

Disc pack components of KT159-030

The KT159-030 brake includes a set of related disc-pack elements. KT159-040 is referenced as the support disc that receives piston force from the cylinder block. KT159-120 is referenced as a rotating metal-ceramic disc, engaging with the splines of the KT159-010 nose wheel rim. Stationary bimetallic discs are fixed on the non-rotating side of the nose landing gear brake assembly. The exact disc composition, quantity and allowable wear limits should be verified by the aircraft maintenance documentation and brake passport.

Identification and ordering of KT159-030

Before ordering KT159-030 / KT159.030-1, the aircraft modification, nose landing gear configuration, required quantity, condition and documentation set should be confirmed. It is also necessary to clarify whether the request concerns the complete brake assembly or separate components, such as cylinder block, KT159-040 support disc, KT159-120 rotating discs, stationary discs, seals or rubber technical parts kit. The item may be required for front landing gear repair, wheel-brake system overhaul, operational replacement or spare parts stock for Il-76 aircraft.
