摘　　要：本文初步尝试１＋１对转涡轮设计，试图发现区别于常规涡轮设计存在的问题，探索对转涡轮设计体系的组成和应用策略，对１＋１对转涡轮给出初步评价。A primary design of one counter-rotating turbine is presented. Efforts are devoted to clarifying the differences existed between the design of conventional turbine and counter-rotating tur- bine. The components and strategy involved in the design system of counter-rotating turbine are explored. Initial evaluations about the counter-rotating turbine are obtained. It is concluded that counter-rotating turbine could have higher efficiency than conventional one, and the weight of low pressure turbine vane can be reduced 30 percent. The design system of the conventional turbine is suitable for counter-rotating turbine.
