Ground mooring method for large amphibious aircraft

Abstract

The invention provides a novel aircraft ground mooring method for optimizing an open parking mooring scheme of a large amphibious aircraft. According to the invention, a ground mooring method that the nose and the tail are laterally pulled downwards and fixed by using two mooring ropes respectively and a single mooring rope and the ground form a 45-degree angle is adopted, so that the two mooring ropes can generate tensile force exceeding the rated load under the rated load, and the requirement of the large amphibious aircraft for parking and mooring in the open air is met; through a wing buoy support, a large-scale working ladder does not need to be used when wings are moored on the ground, so that the mooring operation height and difficulty of the aircraft are effectively reduced; and the split buoy support is small in operation size, convenient to carry or transport and capable of being delivered to an operation airport in time, so that the maneuvering performance of the large-scale amphibious aircraft is improved, and the large-scale amphibious aircraft is more suitable for urgent requirements of emergency rescue tasks.

Description

Technical field: [0001] The invention belongs to the technical field of maintenance support, and in particular relates to a ground mooring method for a large amphibious aircraft. Background technique: [0002] During the period when the aircraft is parked in the open air (under the approved wind speed limit), under the action of strong winds, the lift force generated may exceed the weight of the aircraft itself, causing the aircraft to slide or roll on the ground and hit other aircraft or objects, causing aircraft ground accidents. [0003] Large amphibious aircraft is an upper monoplane, which has a larger lift coefficient than a lower monoplane. Generally, four-point ground moorings are used, that is, the nose and tail of the aircraft are moored to prevent the aircraft from sliding; Wings are used to prevent the aircraft from rolling. However, due to the structural load and hydrodynamic performance requirements of the wing buoys, there is no ground mooring interface under...

Problems solved by technology

However, due to the structural load and hydrodynamic performance requirements of the wing buoys, there is no ground mooring interface under the wing buoys, so only the wing

[0004] The wings of large amphibious aircraft are relatively high from the ground (generally about 5m), and large working ladders are required for tethered operations, and they are operated at high altitudes, which significantly increases operational difficulty and safety risks, especially for remote emergency rescue missions, which may be due to There is no large working ladder or large hangar at the operating airport, which makes it impossible to park the aircraft, which seriously affects the development of emergency rescue tasks
