民用航空发动机进气道防冰系统设计方法研究

Civil Aero-engine Inlet Anti-icing System Power Requirement Definition Methodology Investigation

民用航空发动机进气道防冰系统为发动机在结冰条件下运行提供了安全保障,中国民航总局颁布的适航条款中对民用航空发动机在结冰环境中的运行也提出了安全性要求,但国内针对进气道防冰系统设计工作开展的研究较少,本文针对民用航空发动机进气道笛形管防冰系统的设计,介绍了国内外热气防冰系统的研究进展,阐述了进气道防冰系统的设计依据、设计方法、优化方法及试验验证方法,为民用航空发动机进气道防冰系统设计相关工作提供参考。

The civil aero-engine inlet anti-icing system provide the guarantee to the engine operation safe in the icing condition. The Civil Aviation Administration of China published the regulation to the civil aero-engine op-eration in the icing condition. However, there is less relevant research work about anti-icing system design. In this paper, the research progress for inlet piccolo anti-icing system in recent years is introduces. The design re-quirement, design methods, optimization methods and test verification methods are described which provide a reference to the design of the civil aero-engine inlet piccolo anti-icing system.
