Landing gear development history
Oct 09, 2018

On December 17, 1903, for the first time in human history, a powered, manned, sustained, stable, and maneuverable aircraft that was heavier than air successfully flew. This is the "Flighter One" made by the Wright brothers. However, on this plane, there is no shadow of the modern landing gear, but a pair of devices similar to skids. It uses a wheeled trolley to take off on the rails by means of a drop hammer device, as shown on the right.

On the "Aircraft-14BIS" of Santos-Dumont in 1906, there was a modern landing gear. After the wheeled landing gear, the aircraft's movement on the ground, the pre-flight run and landing performance have been greatly improved, as shown on the right.

However, with the gradual success of the aircraft, the aircraft design quality and flight speed continue to increase. Improving the take-off and landing performance of an aircraft has become one of the urgent problems to be solved. The aircraft of the First World War had already had a shock-absorbing landing gear. These landing gears use a rubber cord around the shaft and secure them to the strut for shock absorption. The landing gear at this time entered the role of landing damping.

With the increase in flight speed. Modern aircraft landing gear is required to be retractable to reduce air resistance during flight. Therefore, the structural form of the landing gear has also evolved from a structural type to a pillar type and a rocker type.
