摘要:

为探索跨声速转子叶片在不同条件下的表面积冰和冰脱落特性规律,获得冰脱落位置和断面结构,以跨声速风扇转子叶片为研究对象,基于自然低温的冰风洞试验系统,在典型结冰条件下,开展转子叶片的积冰与脱落研究。结果表明:跨声速风扇转子叶片吸力面和压力面均有积冰生成,积冰脱落从叶片两面同时开始。随着来流温度降低,叶片表面的积冰冰形经历由明冰到混合冰再到霜冰的过程。冰脱落受叶片转速、升转速率和来流温度影响,不同条件下冰脱落所需要的时间和脱落程度均不同。来流温度不变的情况下,叶片积冰转速增高,脱冰转速单调递增,而脱冰时间单调递减,叶片压力面和吸力面脱冰量均随叶片转速增加而增大。随着升转速率增大,叶片表面的积冰脱落程度单调递增而积冰脱落时间单调递减。不同温度下脱冰,随着温度降低,积冰脱落程度减小,积冰从叶片表面脱落的时间增长。在一定范围内,基于试验数据所建立的脱冰转速预测模型能够较好地预测不同工况下的脱冰转速。

Abstract:

To investigate the laws of surface ice accretion and ice shedding characteristics of transonic rotor blades under different conditions, and to obtain the ice shedding position and cross-sectional structure, study takes transonic fan rotor blades as the resea -rch object. Based on an ice wind tunnel system with natural low temperature,test studies on ice accretion and shedding of rotor blades were carried out under typical icing conditions. The results show that ice accretion occurs on both the suction surf-ace and pressure surface of the transonic fan rotor blades, and ice shedding starts simultaneously from both surfaces of the blades. As the ambient temperature decreases, the ice shape on the blade surface changes from glaze ice to mixed ice, and then to rime ice. Ice shedding is affected by blade rotational speed, rotational acceleration rate, and ambient temperature; the time required for ice shedding and the degree of ice shedding vary under different conditions. When the ambient temperature is constant, as the ice-accreting rotational speed of the blade increases, the ice-shedding rotational speed increases monotonically, while the ice-shedding time decreases monotonically. Meanwhile, the ice shedding amount on both the pressure surface and suction surface of the blade increases with the increase of blade rotational speed. When ice shedding is conducted by increasing the rotational acceleration rate, as the rotational acceleration rate increases, the degree of ice shedding on the blade surface increases monotonically, while the ice shedding time decreases monotonically. For ice shedding under different temperatures, as the temperature decreases, the degree of ice shedding decreases, and the time requirde for ice to shed from the blade surface is extended.Within a certain range, the prediction model for ice shedding rotational speed established based on test data canaccurately predict the ice shedding rotational speed under different operating conditions.
