开式转子发动机设计与应用浅析

Analysis on design and application of open rotor engine

全球气候正呈现出逐渐变暖的趋势,欧盟航空业需要为降低飞机的温室气体排放和噪音作出努力。由空客公司和斯奈克玛公司带头进行的研究发现,将在2030年推出的装备反向旋转的开式转子发动机的短-中程大型客机在技术上是可行的,而且也将符合国际民航组织的新噪声限值规定,研究表明开放转子发动机是降低燃料消耗和减排的最佳选择。下一步要做的是使该款飞机更加经济,特别是减少飞机将增加的重量,以满足叶片高速安全性要求,增加的重量将对开式转子发动机的燃耗情况产生不利影响。

The global climate is showing a gradual warming trend,the European aviation industry needs to make efforts to reduce greenhouse gas emissions and noise.Spearheaded by Airbus and SNECMA research found that in 2030 to launch equipment reverse rotation with an open rotor engine short - to medium range airliner in technology is feasible,but also would be consistent with the international civil aviation organization the new noise limit value in terms of the Ming open rotor engine is the best choice for fuel consumption and emission reduction.The next step to do is to make the aircraft more economical,especially reduce the aircraft will increase the weight of, to meet the high speed blade safety requirements,increase the weight will be the open rotor engine fuel consumption situation produce adverse effects.
