The invention provides a catapult-assisted take-off device of an aircraft and an aircraft carrier. The catapult-assisted take-off device comprises an elastic rope, a working wheel and a main power device. The elastic rope is used for dragging the aircraft, the working wheel comprises a gear flywheel and a working wheel body connected with the gear flywheel through a rotary shaft, and the gear flywheel and the working wheel body can rotate around the axis of the rotary shaft. A spiral groove is formed in the periphery of the working wheel, a spiral line body is formed by the central line of the spiral groove in a surrounding manner, and the spiral line body sequentially comprises a first cylindrical part and a second conical part along a rotary axis. When the working wheel rotates, the elastic rope is wound in the spiral groove and is dragged along with rotation of the working wheel. The catapult-assisted take-off device can achieve dynamic balance of the rope and the aircraft in the catapult-assisted take-off process. Energy needed by catapulting of the catapult-assisted take-off device of the aircraft is stable in source, the operating conditions of the aircraft carrier are not influenced, it can be guaranteed that the aircraft takes off with constant acceleration in a catapulting manner, and catapulting efficiency can be above 90%. Therefore, faster takt time can be achieved, and the catapult-assisted take-off device can be applied to ski-jump decks.
