The invention relates to a method and a device of whole course uniformly-accelerated
mechanical traction high-speed take-off of a shipboard aircraft and aims at solving the problems that in the prior art, auxiliary take-off power is little, take-off speed is slow, and cost is high. A high-power
winch is utilized for traction of take-off of the shipboard aircraft. The high-power improved
winch arranged at the head of a ship drags, in the forward direction, the shipboard aircraft to take off. A low-power universal
winch arranged at the
tail portion of the ship drags, in a reverse direction, a hook
system or a reciprocating car mactched with the shipboard aircraft to restore to an original position. The high-power improved winch is improved in the following way: some gears of a speed reducing box are eliminated, the rotating speed of a roller is increased, and the roller is changed into a roller with a larger
diameter. According to the device, the high-power winch is arranged under a
deck and drags the hook
system or the reciprocating car through steel wire ropes, and then the hook
system or the reciprocating car drives the shipboard aircraft. Due to adoption of the high-power independent-power winch, high-speed take-off of any heavy-type and large-scale
airplane full of oil, bombs or various materials is ensured, the take-off is high in quality, low in cost, safe, free of
pollution, free of interference, and onboard fuel is saved. The device has the advantages of low cost, little investment,
high energy utilization rate, little
mechanical equipment, and the like, and is far better than an electromagnetic
catapult and a steam
catapult.
