The invention relates to the technical field of engine case containment study, in particular to an engine case containment test device. The test device comprises a ground test bed, a driving mechanismwith a driving shaft, a driving shaft flange, an adapter shaft, a test rotor, a case fixing plate, a case, a flange bracelet, a flange protective cover and a protective cone-shaped cylinder, whereinthe driving shaft flange is coaxially arranged on the driving shaft; the adapter shaft is fixed at the bottom end of the driving shaft flange; the test rotor is fixed at the bottom end of the adaptershaft and is provided with blades; the case fixing plate is fixed on the bottom face of an upper cover of the test bed; the case sleeves the outer side of the test rotor; the flange bracelet sleeves the outer side of the driving shaft flange; the flange protective cover sleeves the outer side of the flange bracelet and is fixedly connected with the case fixing plate; and the protective cone-shapedcylinder coaxially sleeves the outer sides of the flange protective cover and driving shaft flange. The engine case containment test device has the advantages that containment test can be carried outon the engine case, through the limitation of the flange bracelet, flange protective cover and other structures, the blades and the case can be prevented from rubbing, and it is limited that the driving shaft bends and deforms.
