随着发动机工作范围的不断扩大,采用相似理论、即建立一种能考虑外界条件广泛变化的通用特性、已是必然趋势、因此在设计发动机调节系统时,首先就要根据相似理论定出换算参数、确定发动机的动态特性,再根据调节规律得到调节工作线。然后就可进行调节器设计。但如何选择参数组合、建立函数关系,又是设计中遇到的主要问题。 本文对此设计步骤作了简要的归纳和分析,并结合状态调节和加速调节,举例说明了调节器的实现问题。但要将理论付诸实现,其中还有不少实际问题需要解决。文中着重对我国新引进的某型涡扇发动机的调节系统作了详尽的分析,用以阐明在具体设计调节器时是如何解决这些实际问题的。
With the continuous expansion of the working range of engines, it is an inevitable trend to adopt a similar theory, that is, to establish a universal characteristic that can take into account the wide variation of external conditions. Therefore, when designing an engine regulating system, the conversion parameters must be determined according to the similarity theory , Determine the dynamic characteristics of the engine, and then adjust the line of work according to regulation. Then the regulator can be designed. But how to choose the parameter combination and establish the function relationship is the main problem in the design. This article made a brief summary of the design steps and analysis, combined with the state adjustment and acceleration adjustment, an example of the realization of the regulator. But to put theory into practice, there are still many practical problems to be solved. This paper focuses on the introduction of a new type of turbofan engine regulation system made a detailed analysis to illustrate the specific design of the regulator is how to solve these practical problems.
