本文介绍了美国国家航空和宇宙航行局（NASA）在系统水平上为商用和军用运输机开发生产成本估算关系（CER）和重量估算关系（WER）的研究结果。所考虑的系统对应于军用标准1374中定义的标准重量组，并列出。这些系统构成了一架不包括发动机的完整飞机。每个系统的CER（或在某些情况下的CER）都将重量作为关键参数。重量可根据详细的重量说明（如有）确定，或使用基于初步设计期间通常可用的技术和性能特征而制定的WER确定。所开发的CER为初步估算飞机的生产成本提供了非常有用的工具。同样，WER也提供了一个非常有用的工具，用于根据概念设计信息对飞机重量进行初步估算。
The results of a NASA study to develop production cost estimating relationships (CERs) and weight estimating relationships (WERs) for commercial and military transport aircraft at the system level are presented. The systems considered correspond to the standard weight groups defined in Military Standard 1374 and are listed. These systems make up a complete aircraft exclusive of engines. The CER for each system (or CERs in several cases) utilize weight as the key parameter. Weights may be determined from detailed weight statements, if available, or by using the WERs developed, which are based on technical and performance characteristics generally available during preliminary design. The CERs that were developed provide a very useful tool for making preliminary estimates of the production cost of an aircraft. Likewise, the WERs provide a very useful tool for making preliminary estimates of the weight of aircraft based on conceptual design information.
