民用涡轴发动机部件级效能评估模型研究

Research on Component Level Effectiveness Evaluation Model of Civil Turboshaft Engine

效费分析是科学策划航空发动机研制工作的重要前提,是对航空发动机效能与费用的系统性、权衡性分析。效能评估是效费分析的基础,也是难点之一,目前国内没有对航空发动机效能评估的直接测量或精确计算方法。通过结合国外成熟理论方法以及国内专家的经验,建立了一套民用涡轴发动机典型部件的效能评估模型,为民用涡轴发动机部件的效能评估提供参考。

Cost effectiveness analysis is an important prerequisite for scientific planning of aeroengine development. It is a systematic and trade-off analysis of aeroengine efficiency and cost. Efficiency evaluation is the basis of cost-effectiveness analysis and one of the difficulties. At present, there is no direct measurement or accurate calculation method for aero-engine efficiency evaluation in China. Based on the mature theories and methods of foreign countries and the experience of domestic experts, this paper establishes a set of efficiency evaluation model of typical components of civil turboshaft engine, which provides a reference for the efficiency evaluation of civil turboshaft engine components.
