航空发动机研制费用测算方法分析

针对航空发动机研制阶段的费用测算进行研究,费用测算应遵循基本的原则并按照一定的流程开展工作.发动机研制费用测算包括工程和财务2种模式,需按照研制所开展的工作种类及等级建立费用分解结构.在不同的发动机研制阶段,研制费用测算的方法可采用专家论证法、自上而下法、比较法和参数化法等.在进行费用测算时需要考虑费用的时间价值及技术、经济、资源和管理等环境因素对费用的影响,可作为航空发动机研制立项及过程管理中费用测算参考.

Calculation Method of Aeroengine Development Cost

The calculation of aeroengine development cost was studied according to the basic principle and working process. It was engineering and finance modes in the aeroengine development cost, which in accordance with the type and level of development of the work to established the cost breakdown structure. The calculation method was adopted by expert demonstration, top-down and comparative law and parameterized methods in different stage of aeroengine development. The effect of time value, technology, economy, resources and management on the cost calculation was considered, which take reference to the cost calculation of aeroengine development and process management
