М = К • Ек,
где М - масса кольцевого обода с фланцами;
Ек - величина энергетического воздействия, Дж;
К - коэффициент пропорциональности, равный 30 • 10-6...50 • 10-6 кг/Дж,
а толщина стенки корпуса над лопатками турбомашины соответствует соотношению:
где Т - толщина стенки корпуса, мм;
Ек - величина энергетического воздействия, Дж;
G - прочность материала при статическом изгибе, МПа;
К1 - коэффициент пропорциональности, равный 0,8...1,3 (МПа • мм)/Дж;
f - расчетный запас прочности, равный 1,2.A device for holding fragments of a rotor of a turbomachine, comprising a hollow body located in the rotor bearings, comprising at least one disk with blades, the body being provided with an annular rim above the rotor blades and covered by a casing, characterized in that the annular rim is provided with two inner flanges made with a rim in the form of a single monolithic part, and fastened to the housing along two annular belts, one of the flanges is located in front of the entrance of the rotor blades, and the other behind their exit, the radial wall thickness of the body Ca above the rotor blades does not exceed the radial thickness of the rim wall, and the radial removal of the rim from the housing is made within 1.0 - 1.8 of the height of the rotor blades, while the mass of the annular rim with flanges corresponds to the magnitude of the energy impact of the rotor fragments:
M = K • Ek,
