The invention discloses a convolution acceleration taking-off scheme. A fixed wing aircraft carries out a circular motion in a horizontal bar sample mechanical device, convolutes around a horizontal bar just like a gymnast, and is released to take off at a proper position after being accelerated to the required speed. The device is capable of providing fuel oil for the aircraft, so that the aircraft is in a full-oil and full-load state when taking off. When the aircraft takes off on a shaking aircraft carrier, auxiliary equipment is required to counteract a gyroscopic effect generated by high-speed rotation of the aircraft carrier, so that the aircraft takes off safely. The device can be additionally provided with an aircraft engine for boosting, so that the taking-off time is shortened. The mechanical device adopted in the taking-off scheme is simple, convenient in maintenance and small in occupied floor; multiple aircrafts can be matched with the aircraft carrier, so that the total taking-off speed is greater than catapult-assisted take-off speed, and the combating speed and the combating efficiency areimproved.
