本文叙述了对用于火箭、直升机、运输机的燃气涡轮发动机及船用高速柴油机增压器的锻、铸造耐热合金、高强度铝合金的不同结构轮盘转子破裂准则所作的预先确定;在旋转试验台上进行的轮盘转子破裂试验。成功地证明了几种破裂准则(包括K1c 准则)对不同材料和结构,的轮盘转子的适用性。
This paper describes the pre-determination of rotor rupture criteria for different structures of forged and cast heat-resistant alloys and high-strength aluminum alloys for gas turbine engines used in rockets, helicopters and transport aircraft and marine high-speed diesel superchargers. In rotation tests Drum rotor rupture test on stage. Successfully proved the applicability of several fracture criteria (including the K1c criterion) to the rotor of different materials and structures.
