使用金属材料的设计需要应对较重的重量、过度浪费和制造效率等挑战。并且随着飞机制造商越来越关注通过减轻材料的重量以及缩短上市时间来提高燃料效率以及降低整体成本，使得使用金属作为原材饱受诟病。而基于聚芳醚酮（PAEK）的复合材料已经在应对这些挑战中初显成效。
不断增强的聚芳醚酮基复合材料能够减轻最高70%的材料重量，并具有较强的抗化学腐蚀性，同时具有高于金属材料5倍的机械性能。《混合模塑技术为聚合物结构部件提供支持》介绍了一种新的基于聚芳醚酮的聚合物以及复合材料混合模塑成型技术。
旋翼直升飞机的安全性需要多个重要的流体系统、组件和进程一起工作。极端温度下的保护以及减震等问题必须在旋翼直升机离开地面之前解决。除冰和冰冻保护技术、温度阀门和加热器、线型和旋转制动器以及流体阀门等等，只有解决了这些问题，才能够提高旋翼直升机部件的使用寿命和可靠性。详情请见《旋翼直升飞机的关键部件》一文。
现代数控磨削机床都设计能够避免机器的振动,并使用先进的软件对一些可能影响生产制造的因素比如动态和静态的强度进行评估。尽管在设备的设计方面有了很大的进步，但是在航空航天业的应用中研磨加工还是变得越来越困难。
在对高镍合金、陶瓷基复合材料（CMC）和金属基复合材料（MMC）等材料进行加工时，高标准的公差率和严格的材料损耗率（MMR），将加工设备的能力推向了极限，并提高了设备振动产生的可能性。请见本期《精密磨削机床的振动测量》。
