FIELD: testing equipment. SUBSTANCE: process consists in measurement of action of jet engine on primary converter. Action is transferred to primary converter with the help of intermediate member. Action is recorded in pressure chamber where several engines are placed at same time. Cone in which jet engine installation flame is positioned is found in advance and then jet engine installations are so placed that their flame cones do not cross. Then each jet engine installation is switched on in turn, readings of each pickup are recorded in this process. Conclusion on operation of each jet engine installation is made with allowance for errors induced by operation of neighboring jet engine installations. Proposed bench includes support 1, force measuring pickups 2, intermediate member 5 to transfer force linked to recorder. Jet engine installations 4 are positioned in pressure chamber along spiral 7. Force measuring pickups 2 are mounted on support 1 and along spiral 7. EFFECT: expanded functional capabilities. 2 cl, 2 dwg
