PROJECT REPORT ON LANDING GEAR SYSTEMS
Here, I'm sharing with you the outcome from my team and I's project for Aircraft Subsystem Element class. My team was assigned a task to review the landing gear systems of air transport. The landing gear is one of the critical subsystems of an aircraft or helicopter. It is the undercarriage of an aircraft or spacecraft and may be used for either takeoff or landing. The need to design landing gear with minimum weight, minimum volume, high performance, improve life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheels are typically used but skids, skis, floats or a combination of these and other elements can be deployed depending both on the surface and on whether the craft only operates vertically (VTOL) or is able to taxi along the surface. Faster aircraft usually have retractable undercarriages, which fold away during the flight to reduce air resistance or drag. For launch vehicles and spacecraft landers, the landing gear is typically designed to support the vehicle only post-flight, and are typically not used for takeoff or surface movement. The main purpose of the landing gear is to provide structural support and manoeuvrability of the helicopter for the ground operation. It is also meant to absorb unusual loads incurred during landing and also ground operation.
