[0003] The airport ground equipment and facilities are supported by steel frames and placed in designated positions. The design purpose is to support as heavy navigation facility equipment as possible with as light as possible easy-to-fold rods. However, when subjected to unexpected impact in any direction, the easy-to-fold rods should be easy to fold and break to minimize structural damage to the aircraft. When colliding, the easy-to-fold rods must break, bend or yield, and not entangle the aircraft to prevent limiting the safety maneuverability of the aircraft.

[0004] For the easy-to-fold rods that may collide with the aircraft sliding on the ground, they must be easy to fold and break when subjected to a 3000kg aircraft impact at a speed of 50km / h. When colliding, the force exerted by the easy-to-fold rods on the aircraft should be no more than 45KN; the maximum energy exerted by the easy-to-fold rods on the aircraft should be no more than 55KJ in the instant (about 100ms) of the aircraft colliding with the easy-to-fold rods.

[0005] Most of the existing equipment supports are made of steel structure welded or assembled, and the product material itself is relatively hard, which can cause penetration damage to the aircraft. In addition, if the existing easy-to-fold and easy-to-break materials are directly used to form the supports by assembling components, the structure is simple and the stability is not strong.
