The invention discloses a speed-following self-adaptive jet drag reduction method and system and application, and belongs to the technical field of underwater drag reduction. The drag reduction method comprises the following specific steps: arranging a data acquisition module on an aircraft; the data acquisition module is used for acquiring the real-time navigation speed of the vehicle and the flow value of high polymer injection; the control module receives and analyzes the information acquired by the data acquisition module, obtains an injection rate calculated value corresponding to the measured navigational speed by comparing the mapping relation between the navigational speed and the injection rate, and then outputs a control instruction to the driving module until the actual value of the high polymer injection rate is adjusted to be equal to the calculated value; a high polymer solution in the liquid storage module is sucked to a high polymer spraying outlet to be sprayed out by the driving module, and passes through the voltage stabilizing module; and the pressure fluctuation in the high polymer spraying state is absorbed through the pressure stabilizing module. The defects that in the prior art, the injection pressure of an underwater vehicle fluctuates, and the high polymer injection efficiency is low are overcome.
