FIELD: machine building.
SUBSTANCE: bearing support for retention of the shaft in a jet turbine engine in the required direction includes an annular part made from material with shape memory effect, which maintains the original form when the imposed load remains below the threshold value and which is deformed after energy absorption when the imposed load becomes equal at least to the threshold value; at that, the annular part is capable of taking again at least approximately its original form when imposed load becomes lower than threshold value.
EFFECT: providing the possibility of performing repeated shaft alignment after disconnection of guide bearings from low pressure compressor shaft after the jet turbine engine is set to autorotation mode so that destruction of the other guide bearing can be avoided and jet turbine engine structure can be maintained.
