The invention discloses a method for determining the optimal efficiency of a water-based propulsion system based on multi-target optimization. The method comprises the following steps: setting independent variable parameters related to the scale of the water-based propulsion system; distributing volumes of a hydrogen cylinder and an oxygen cylinder according to an electrolysis principle; obtainingthe mass and maneuvering interval time of a propellant (water) required to be carried by the water-based propulsion system under the same load weight and speed increment as those of a traditional chemical propulsion system according to the parameters of the water-based propulsion system; solving an optimal solution set of the gas cylinder volume and the electrolytic tank power of the water-basedpropulsion system by taking the system weight and the maneuvering interval time saved by the water-based propulsion system as targets and utilizing a multi-target optimization method; and selecting proper parameters from the optimal solution set according to task requirements, and calculating the performance which can be provided under the scale. The optimal efficiency design of the water-based propulsion system is realized through the multi-objective optimization method, and the problem of mutual restriction between the efficiency and resources of the water-based propulsion system is solved.
