涡扇加力和多功能推力矢量装置

从加力燃烧室的技术现状、发展需求和制约条件等三方面与主燃烧室进行对比并作全面分析，同时，从来流的温度和压力条件阐述了隐身技术和高膨胀比可调喷管、推力矢量控制的需求。中指出在未来看得见的时间内，加力部件不仅不会取消，而且还会在功能上有新的发展。加力部件上出现新技术是不可避免的，其中常规双层加力、游流加以及采用射流控制或其他新的控制方法的多功能推力矢量装置将很可能出现。本分析可供预先研究作参考。

Turbofan Afterburner and Multi-function Thrust Vectoring System

This paper compares afterburner with combustor by three aspects: state-of-the-art, development requirements and restrict factors, offering an overall analysis. According to flow temperature and pressure condition, it expounds stealth technology and requirements of high - expansion - ratio adjustable nozzle and thrust vectoring control. It is foreseeable that new technologies and functions of afterburner components will be obviously evolved, which possibly include fan mixing afterburner, swirling afterburner and multi - function thrust vectoring system using jet control and some other new control methods. The results of this analysis can be used in advanced researches.
