are an important component of a landing gear system. With tires mounted upon them, they support the entire weight of the aircraft during taxi, takeoff, and landingAircraft Wheels
The typical aircraft wheel is lightweight, strong, and made fromAluminum Alloy
refers to the outer surface of the tire that comes into contact with the runway or landing surface during takeoff, landing, and taxiing.Tread
It refers to the patterned indentations or channels on the surface of an aircraft tire's tread. Grooves
One of the primary functions of grooves is to help disperse water on wet runways.Water Drainage
Depending on the specific tread design, grooves can improve traction on various types of surfaces, including snow, ice, and loose gravel.Enhanced Traction
During the landing and braking process, aircraft tires generate a significant amount of heat due to friction.Heat Dissipation
Grooves also aid in clearing debris, such as small rocks or foreign objects, from the tire's contact area.Debris Clearance
provides structural support to the tire, helping it maintain its shape and strength, especially when the tire is subjected to heavy loads, such as during landing, takeoff, or taxiing. It helps distribute the load and maintain the tire's integritySidewall
The sidewall needs to be flexible to some extent to allow for deformation and compression of the tire as it contacts the runway surface. Flexibility
Aircraft tire sidewalls often contain important information, such as tire size, load rating, speed rating, and manufacturing details. This information is crucial for maintenance personnel and ensures that the correct tires are installed on an aircraft.Tire Identification
Some aircraft tires may have sidewall markings for branding and aesthetic purposes, which can include the manufacturer’s logo or tire brandingAesthetic and Branding
refer to layers of fabric or material that make up the structural body of the tire, often called the tire casing or carcass. Casing Plies
play a critical role in maintaining the structural integrity of the tire and ensuring that it remains securely attached to the wheel during various phases of flight and ground operations.Wire Beads
Wire beads are used to anchor the tire to the wheel rim.
They provide a secure and tight fit, preventing the tire from slipping or rotating on the rim during high-stress maneuvers, such as takeoff, landing, and taxiing.Tire Mounting
Wire beads also help create an airtight seal between the tire and the wheel rim.
This seal is essential for maintaining tire pressure and preventing air from escaping, ensuring that the tire remains properly inflated during flight operations.Sealing
These discs rotate with the wheels and are essential for generating the necessary friction for braking.Brake Discs
also referred to as linings, are attached to the brake calipers and come into contact with the rotating brake discs.Brake Pads
house the brake pads and facilitate their movement. Brake Calipers
The (blank blank blank) is responsible for transmitting the input from the pilot's foot pedals to the brake components. Brake Actuation System
It is a safety feature designed to prevent the wheels from skidding or sliding during braking, especially on slippery or uneven surfaces.Anti-Skid System
are mechanisms that redirect engine thrust forward during landing to assist in deceleration.
They can complement the conventional braking system.Thrust Reversers
Braking is accomplished by applying friction to both sides of the disc from a non-rotating caliper bolted to the landing gear axle flange.
Single Disc Brakes
are used on aircraft where a single disc on each wheel does not supply sufficient braking friction.
Two discs are keyed to the wheel instead of one. A center carrier is located between the two discsDual-Disc Brakes
are heavy duty brakes designed for use with power brake control valves or power boost master cylinders.Multiple-Disc Brakes
typically houses the brake assembly and is connected to the aircraft's landing gear.Inner Wheel Half
usually includes the tire and is exposed to the runway surface during landing.Outer Wheel Half
It is a circular metal plate that attaches to the hub of the wheel and provides a surface for the brake pads to clamp onto when the brakes are applied. Wheel Disc
form a critical part of the wheel bearing assembly, allowing for the smooth and efficient rotation of wheels and other rotating components.Bearing Cup and Cone
helps maintain proper lubrication within the wheel assembly, reducing friction and wear on moving parts. By creating a barrier, it also protects the wheel bearings from environmental elements, contributing to the longevity and performance of the entire wheel system.Grease Seal Ring
are circular metal rings with a small gap, allowing them to be snapped into a groove or recess on a shaft or inside a bore.Snap Rings
is a circular sealing ring made of resilient material, such as synthetic rubber, designed to create a secure and leakproof seal between the components of an aircraft wheel assembly, preventing the escape of fluids or gases.O-Ring
