| 中文摘要: |
| 针对在立项论证阶段对航空发动机项目经费进行快速并有效的估算的问题，基于中国航空发动机的研制现状和型号数据的积累情况，分析了发动机研制经费估算工作的重点与难点以及相应的解决途径，并采用偏最小二乘法建立了航空发动机研制经费估算模型。计算结果表明：该发动机模型精度较高，已经应用于国产某型涡扇发动机的经费测算工作中，并可用于中国未来航空发动机型号的研制经费估算。 |
| 英文摘要: |
| Aiming at estimating the project funds quickly and effectively in the demonstration phase， the emphasis, difficulty and solutions of areoengine development cost estimation were analyzed based on the development status and the accumulated data. The engine development cost estimation model was established by the partial least squares. The calculation results show that the model has higher precision and has been used for a turbofan engine funds predication. It can be used for the development cost estimation of future aeroengine. |
