Technical Field

The invention relates to the technical field of aviation equipment, in particular to a traction accessory applied to helicopter traction.

Background

During maintenance and service of a helicopter, it is necessary to achieve traction of the helicopter to ensure safe directional movement of the helicopter over the ground. At present, helicopters of different types can be defined due to their different take-off tonnage, for example, in the international standard, the tonnage of light and ultra-light helicopters is generally 3 tons or less. The takeoff tonnage of the ultra-light skid type undercarriage helicopter is less than 1 ton; and the takeoff tonnage of the light helicopter is between 1 ton and 3 tons; the takeoff tonnage of the small and medium-sized helicopters is between 3 tons and 6 tons. Therefore, different types of helicopter tractors are required to be equipped for different helicopters, and each tractor is different in appearance, size, principle and the like. For example, a typical skid helicopter has a dedicated tractor interface, typically pulled by a human power, or pulled by a small manual tractor, matching a dedicated tractor; in addition, other types of skid helicopters employ a manually propelled or completely different electric tractor to pull and mate with a tow bar that takes up a relatively large amount of space.

In summary, in the prior art, different types of helicopters need to be matched with different traction devices, the traction devices do not have versatility among diversified helicopters, safety and reliability are low, and operation and maintenance costs are high.
