【摘要】 介绍了风机气垫防磨叶片表面压力的实验研究结果 ,给出了实验方法和实验结果 ,并对该结果进行了详细分析。通过实验研究了主流速度为 10m/s时 ,不同开孔方向、不同射流速度对空心叶片表面压力的影响。实验结果表明 ,叶片表面吹入合适的射流后 ,表面压力比无射流时高更多还原

【Abstract】 The experimental study of aerodynamic characteristics of the air cushion anti erosion fan aero foil is introduced in this paper.Detailed Measurements are made under the conditions of the different jet velocity and te different angle of incidence of jet on the aero foil.Results show that,the pressure distribution in the case of air cushion established is higher than that of no air cushion.
