微射流技术的原理及其应用

介绍了微射流技术的原理及其初步应用。基于非线性系统的演化对初始条件具有敏感依赖这个事实发展起来的微射流技术，由于与常规持续喷射射流控制方式相比具有许多优点，因而在流动和换热控制应用方面取得明显的效果。并指出，随着研究工作的深入，该项技术还可望用于高马赫数飞行体表面气体流动控制、火箭发动机推力方向控制等。

PRINCIPLE AND APPLICATIONS OF MICROJET TECHNOLOGY

The principle and initial applications of the microjet technology are introduced. Based on the sensitive dependence of nonlinear system's evolvement on its initial conditions, the microjet technology has been developed. Compared with the conventional control mode of steady jet, this technology has more advantages. In the fields of aerodynamic flow and heat transfer controls, it has been applied and obtained distinct effects. Along with the deep development of study, the microjet technology will be possibly applied to control the aerodynamic flow of the high speed aircraft surface and the thrust vector of rocket engine.
