Embodiment Construction
[0028] Such as figure 1 As shown, the main towing boat 2 and the auxiliary towing boat 4 arrive at the water area where the accident occurred, and the main towing boat 2 is connected to the front towing point of the aircraft 1 through the quick-release joint of the first towing rope 3, which is the front towing point of the front landing gear of the aircraft 1. The tow point on the water that establishes, the length of the first tow rope 3 ropes is 50 meters; The auxiliary tow ship 4 is connected with the tow point after the aircraft 1 by the second tow rope 5 quick-release joints, and the rear tow point is positioned at the two sides of the aircraft 1 fuselage rear. On the skin, the second traction rope 5 is 100 meters long; the auxiliary traction boat 4 maintains a position directly behind the aircraft 1, and the second traction rope 5 remains in a slack state.
[0029] When the towing aircraft is in a tailwind, such as figure 1 As shown, the main towing ship 2 is located d...

The invention belongs to the technical field of emergency rescue, and particularly relates to an unpowered landing method for a large amphibious aircraft. A main traction ship, an auxiliary traction ship, an onshore traction vehicle, a traction rope and the like are used; the course of the aircraft is adjusted in different wind directions, so that further expansion of accidents can be effectivelyprevented, and secondary accidents and accidents endangering the safety of the aircraft are prevented; damage possibly caused to the aircraft body, the engine, the wings and other parts due to unpredictable reasons in the process that the large amphibious aircraft stays on the water surface can be rapidly relieved, economic and property losses are greatly reduced, and national large equipment is protected against unnecessary damage. The unpowered landing method for the large amphibious aircraft not only has excellent practicability, but also has good demonstrativity, and has huge potential economic benefits; the method can be widely applied to the fields of aviation and salvage lifesaving, and has extremely high popularization and application values.
Description
technical field [0001] The patent of the present invention belongs to the field of emergency rescue technology, and specifically relates to the emergency rescue of an aircraft in a powerless state in water. Background technique [0002] Large amphibious aircraft can not only take off and land on land, but also take off and land on water surfaces such as rivers, rivers, lakes, and seas. Landing on water has completely different objective conditions from those on land, so it has its own distinctive characteristics. Due to the external objective environment, such as wind speed, wind direction, swell, sea current, etc., during the take-off and landing of large amphibious aircraft, it is more difficult and more demanding than land take-off and landing, and the aircraft itself is more prone to various unforeseen events. Fault. [0003] Especially when the aircraft power system fails to work normally on the water surface, in order to prevent the aircraft from drifting on the water...
