What are the different types of helicopter landing gear?

What are the different types of helicopter landing gear?

When it comes to landing gear, helicopters have two basic types: skids and wheels. Skid gear is always fixed and wheels can be fixed or retractable.

What are the differences between aircraft wheels which are designed for tube and tubeless tires?

The inner sidewall of a tire is covered by the tire inner liner. A tube-type tire has a thin rubber liner adhered to the inner surface to prevent the tube from chafing on the carcass plies. Tubeless tires are lined with a thicker, less permeable rubber.

What is the exterior lip that holds the tire in place?

The (B) RIM FLANGE is the exterior lip that holds the tire in place.

What is tyre creep?

For tyres fitted with an inner tube, tyre creep damages the valve by forcing it against its seating in the wheel. If such damage goes undetected, it can result in a tyre burst, with potentially disastrous consequences during take-off or landing.

What is one major disadvantage to the tail wheel design?

DISAVANTAGES. Taildragger aircraft possess a small number of disadvantages compared to nosewheel aircraft. The tailwheel can drop into holes in the ground, especially on soft fields. Main tires can also drop in holes, and thus potentially nose over and strike the propeller.

Why are aircraft wheels referred to as tyres?

Tires withstand extreme heat and stress until the aircraft is safely stopped. Few aircraft components take more daily abuse than the tire and wheel assembly. Readers outside of North America likely prefer the spelling “tyre” when referring to the rubber portion of an aircraft wheel.

Which is the correct spelling tyre or tire?

Few aircraft components take more daily abuse than the tire and wheel assembly. Readers outside of North America likely prefer the spelling “tyre” when referring to the rubber portion of an aircraft wheel. Please bear with me as I use the spelling common in my neighborhood.

What is the pressure of an aircraft tire?

Large aircraft tire pressures are ridiculously high. A Boeing 767-300 main wheel is inflated to 205 psi. The high pressure supports the tire’s maximum rated load of 51,000 lbs. Aircraft wheels incorporate safety devices to protect the aircraft and personnel working nearby.

Where are the chines on an aircraft wheel?

Chines are sometimes found on the nose wheels of aircraft with fuselage mounted engines. The edges of the tire sidewalls have a curved protrusion (chine) that deflects standing water outward to reduce water ingestion into the engines. The Boeing 727 uses chined nose wheel tires as well as several other aircraft with fuselage mounted engines.
