On February 6, India's domestic light fighter LCA "Brilliance" and MiG-29K carrier aircraft took off and landed on its domestic aircraft carrier "Vikram" for the first time, and once again entered the public view. Times have changed, which does not prevent the author from recalling that a few years ago, there was a "famous scene" of tractor towing carrier aircraft on the last generation of Indian aircraft carrier "Virat". Is it feasible for the tractor to tow the carrier aircraft? Is it a cost-effective innovation? Or a farce? This matter has to start with the important role of the aircraft carrier - the deck tractor. If we say that the carrier aircraft is the "spotlight protagonist" on the aircraft carrier stage, the deck tractor is an unknown and indispensable "behind-the-scenes porter". Its daily work is to transfer the carrier aircraft to the takeoff position, and then to the parking position after landing. This work should not be looked down upon. Although the carrier aircraft is equipped with wheels, it has no "support" from the tractor, and it is almost "impossible to move" on the deck. It is even more difficult to make a carrier-based aircraft turn by itself and perform a "reverse parking" or "side parking". Moreover, the carrier-based aircraft parked on the aircraft carrier is directly related to the combat effectiveness, so it has high requirements for scheduling. Affected by the working environment, the deck tractor should ensure that it can travel smoothly between all types of fighter planes when sailing at sea. It requires not only sufficient power, small size, flexible scheduling, but also materials and manufacturing technology that can adapt to the severe environment such as high temperature, high humidity, high salt fog and sea water erosion, and take into account the properties of radiation resistance and electromagnetic compatibility. Nowadays, few countries have the ability to independently develop aircraft carrier tractors. Because the tractor is difficult to manufacture and expensive, the Indian Navy has not equipped this special equipment for a long time. In order to solve the problem of shipborne aircraft traction, they looked at the tractor. The carrier-based aircraft on the Indian aircraft carrier are mainly light fighters such as Harrier fighter and MiG-29K. The tractor power can really pull the carrier-based aircraft, and the price is low, so it is not a solution. However, using tractors as tractors has some defects that cannot be ignored. Regardless of whether the tractor will damage the deck, its power is always limited, and it can only be "helpless" in the face of heavy shipborne aircraft. Due to its large volume and large turning radius, it is difficult to achieve high precision in traction, and it may even bruise the wings and other components of other shipborne aircraft around, which are all its fatal weaknesses. The efficiency in wartime is naturally far less efficient than the tractor with a turning radius of 0 and small size. Not only that, because of the height of the aircraft, there is more upward force when towing the aircraft, and a slight carelessness may damage the landing gear and other important parts, while the special deck tractor is mostly hydraulic transmission, which can realize stepless speed change and avoid a large impact on the aircraft. It is difficult to predict the wind and cloud at sea. If a huge wave causes the tractor to slip or roll over, it may also bring greater safety hazards, and the gains outweigh the losses. After the aircraft carrier "Wickland" was put into service, the author has not seen any report on tractor tractor tractor yet, followed by the MOTOTOK aircraft tractor imported from Germany, a civil electric remote control aircraft tractor. Because of its compact appearance, it is also called "electric flat panel". Small size, but not small tractive force. The civil model with the largest tractive force can even drag 1
