AERODYNAMIC MOMENTS CONTROL OF WING MODEL USING PLASMA JET

为考察火花放电等离子体射流控制机翼气动力矩的效果,在NACA0021平直机翼模型上安装火花放电等离子体射流发生器,通过改变射流发生器安装位置、射流角度及加载电参数,研究其控制机翼模型气动力矩的性能及机理。在NACA0021机翼模型近前缘处,布置2个火花放电等离子体射流发生器,采用气动力测量技术,在来流风速为20 m/s时测得,攻角-4°~10°时,滚转力矩系数最大减小了0.0024,攻角为12°~16°时,滚转力矩系数最大增加了0.0021;偏航力矩系数最大减小了0.00097。实验研究结果表明:等离子体射流可改变机翼模型横航向气动力矩,并可通过改变射流角度和加载电压频率调节等离子体射流控制横向气动力矩的效果。To investigate the control effect of Spark Discharge Plasma Jets(SPJs) on the aerodynamic moments of a wing, SPJ generators were used for active flow control experimental study on an NACA0021 straight wing model. The location of SPJ generators along the chord of the airfoil, the jet flow direction relative to the chord, and the driving voltage parameters were changed to research the control effect and mechanism of SPJ generators on the aerodynamic moments of a wing model. The aerodynamic moments were measured with a six-component balance at a wind speed of 20 m/s. Two SPJ generators, arranged near the leading edge, reduced the rolling moment coefficient by a maximum of 0.0024 for angles of attack-4°~10°, but increased the rolling moment coefficient by a maximum of 0.0021 for angles of attack 12°~16°. The yaw moment coefficient was reduced by a maximum of 0.00097. The results show that aerodynamic moments control of wings can be realized using SPJs. The control effect of SPJs on the aerodynamic moments is changeable by adjusting the driving voltage frequency and the jet flow direction relative to the chord.航空科学基金项目(20141368007);; 福建省自然科学基金项目(2010J01014

New Method for Analyzing Raman Spectra of Hydrogen-free Diamond-like Carbon Films

dlC薄膜的拉曼光谱表征主要依靠d峰和g峰的强度比值(Id/Ig)来定性判断SP3含量,但当SP3所占百分比高于20%时,Id/Ig值对SP3含量的变化不敏感,判断的误差很大。采用直流磁控溅射和多弧离子镀制备了一系列无氢dlC薄膜样品,并测量了样品的拉曼光谱和维氏硬度。通过数据分析,发现薄膜硬度和拉曼光谱中的g峰半峰宽具有很好的相关性,因而提出通过g峰半峰宽来定量判断dlC薄膜中SP3含量的拉曼光谱表征新方法。The ratio between intensities of the D peak and the G peak(ID/IG) is used to estimate sp3 content of the DLC films.However,this method has limitations.When sp3 content exceeds 20%,ID/IG has very low correlations with the content of sp3,therefore,estimation of sp3 content using this method could lead to significant error.DC-magnetron sputtering and multiple-arc ion plating are used to deposit a series of hydrogen-free diamond-like carbon samples.Raman spectra and Vickers hardness of samples were measured and analyzed.A strong correlation between the hardness and G-peak's full width at half maximum(FWHM) was discovered.The results show that it's feasible to measure the content of sp3 by using the G-peak's FWHM in Raman spectra.福建省半导体照明工程技术研究中心资助项目(2006H0092
