航空發動機是飛機的「心髒」，也被譽為「工業皇冠上的明珠」，其制造集成了現代工業中的很多尖端技術，涉及材料、機械加工、熱力學等多個領域。有人說，如果把工科學科統統算上，大部分都要把最高成就獻給航發。而隨著各個國家對發動機性能的要求越來越高，處於研發、應用中的新結構、新技術、新工藝等依然在不斷挑戰現代工業的高峰。而其中一個對提高航空發動機推重比起到重要作用的，就是整體葉盤。
The aircraft engine is the "heart" of the aircraft and is also known as the "crown jewel of industry". Its manufacturing integrates many cutting-edge technologies in modern industry, involving materials, mechanical processing, thermodynamics and other fields. Some people say that if all engineering disciplines are counted, most of them will dedicate their highest achievements to aircraft engines. As countries have higher and higher requirements for engine performance, new structures, new technologies, and new processes in research and development and application are still constantly challenging the peak of modern industry. One of the important factors in improving the thrust-to-weight ratio of aircraft engines is the integral blade disk.
