The invention relates to a water forced landing test system and a test method. The test system comprises an ejection device for ejecting an aircraft scaling model, a water pool for the scaling model to perform a dampening test, and a first data acquisition module for acquiring motion characteristic information of the scaling model in a dampening process, the second data acquisition module is used for acquiring the stress characteristic information of the scaling model in the dampening process; the data processing module is used for analyzing the change relation between the motion characteristic information and the stress characteristic information; the ejection device comprises an ejection sliding rail, an ejection trolley in sliding fit with the ejection sliding rail, a locking and releasing mechanism and an ejection action mechanism. The ejection action mechanism comprises a driving assembly and an intercepting assembly, wherein the driving assembly applies different ejection forces to the ejection trolley at different speeds, and the intercepting assembly is used for intercepting the ejection trolley so that the scale model can be ejected and separated. According to the invention, the relation among the motion characteristic, the fluid dynamic characteristic and the strength characteristic of the aircraft in the landing process can be tested and analyzed.
