摘　　要：粉末高温合金涡轮盘是高推重比航空发动机研制的关键。由于粉末高温合金材料的特殊性,为了保证粉末高温合金轮盘的可靠性,需要修正传统轮盘强度和低循环疲劳寿命设计技术并进行验证。本文设计了亚尺寸结构的粉末高温合金轮盘,并对其进行了计算及分析,最后在试验器上进行了试验验证。该亚尺寸轮盘研制成功对高推重比涡轮盘的研制有重要意义。FGH96 P/M superalloy turbine disk is an important technology of aeroengine with high thrust/ weight ratio. Considering the features of P/M superalloy, the traditional strength and LCF life design must be modified and validated to ensure the reliability of P/M superalloy turbine disk. In this paper, we designed a sub-scale P/M superalloy turbine disk, it had been Calculated and analyzed, and finally an experimental investigation was made on a test rig. The achievements on sub-scale P/M superalloy turbine disk have importance to turbine disk with high thrust/weight ratio.
