航空发动机叶片 meaning in English
blade of aviation engine
Examples
- The blade inner channel cooling is very important in the design of turbine blade , with the ever - increasing inlet temperature , the new heat transfer enhancement structures of higher performance are demanded . because of the complexity of the flow and heat transfer of the blade inner channel cooling , the numerical modulation is superior to the experiment . this thesis studied the blade inner channel cooling with the method of numerical modulation
叶片内部通道冷却在航空发动机叶片的设计中占有重要的位置，航空发动机进口温度的增高对其提出了更高的要求。由于叶片内部通道冷却的流动与传热的复杂性，数值模拟较实验的研究方法有其优越性，本文利用数值模拟的方法对叶片内部通道冷却进行了研究。 - Directionally solidified refractory metal matrix eutectic in - suit composites possess excellent mechanical and physical properties such as low density , high enduring temperatures , good room - temperature fracture - toughness and high elevated - temperature strength , therefore are expected to be used as a new type of ultra - high temperature structural materials
定向凝固难熔金属基共晶自生复合材料由于具有密度低、承温能力高、室温断裂韧性好、高温强度高和高温持久寿命长等性能优势，有望成为新一代航空发动机叶片用超高温结构材料。 - At first , the model about information requirement in manufacturability evaluation is set up . based on the feature technology and object - oriented mechanism , the manufacture - oriented part model with three levels ( namely part , feature and geometry ) and the resource model is build ; secondly , the evaluation guidelines on the basis of evaluation strategy of fining with levels is constituted ; thirdly , an evaluation method according the evaluation guidelines is put forward , which is the rule - based and fuzzy evaluation - based method associated with resources . fourthly , a manufacturing - oriented evaluation system for machining blade part is built
以特征技术为基础，面向对象的编程机制为手段，建立了面向制造的三层次(即零件层、特征层、几何层)零件模型，同时进行了面向制造的资源建模；第二，采用分层逐步细化的评价策略，建立可制造性评价指标；第三，以评价指标为基础，采用基于约束规则和模糊综合评判的加工可行性评价方法；第四，以ug为开发平台， vc6 . 0为编程工具，航空发动机叶片为应用对象，初步构建了面向制造的叶片类零件的可制造性评价系统。
