The analysis of the pilot-induced oscillation is carried out in general by usingthe simulated methods or flying tests. For the need of the design calculations, however, the writer through consulting the related references provides twotheoretical methods, i.e. the frequency response and root-locus methods.At first, the equation of the airplane longitudinal motion, the equation of the control system motion with full-power or no-power, and the related transfer functions are given in this paper.And then, based...

The analysis of the pilot-induced oscillation is carried out in general by usingthe simulated methods or flying tests. For the need of the design calculations, however, the writer through consulting the related references provides twotheoretical methods, i.e. the frequency response and root-locus methods.At first, the equation of the airplane longitudinal motion, the equation of the control system motion with full-power or no-power, and the related transfer functions are given in this paper.And then, based on the closed-lrop dynamic models of the combination of the airplane and control systems, the frequency response of the elevator deflection to stick force input is calculated and the root-locus is plotted. Thus, the tendency of the pilot-induced oscillation may be analylized.In addition, some simplified criterions of the longitudinal pilot-induced oscillation are presented. Some primary influence factors, especially the effect of bobweight in control systems are discussed.

驾驶员诱发振荡问题的分析,一般通过模拟试验或飞行试验进行。但为了设计计算的需要,本文参考有关资料,提出两种理论分析方法,即频率法和根轨迹法。 文中首先给出飞机的纵向运动方程、助力及非助力操纵系统方程以及有关传递函数,然后根据飞机与操纵系统组合的闭环动力学模型,计算舵偏角对杆力输入的频率反应或绘制根轨迹曲线,从而可以分析飞机的诱发振荡趋势。 此外,还介绍了几种纵向驾驶员诱发振荡的简化判据。并对主要影响因素,特别是对操纵系统配重的影响进行了讨论。

Presented in this paper are the experimental results of impingement coolingof two aluminium targets of different sizes with six impingement tubes. The target simulating the leading edge of a turbine airfoil is preheated and cooled by jets of different impingement tubes at various flowrates and distances. The Lumped-Capacity method is used to determine the cooling rate 'of the aluminium target and the mean heat transfer coefficients which are in turn correlated indimensionless parameters. With the aid of...

Presented in this paper are the experimental results of impingement coolingof two aluminium targets of different sizes with six impingement tubes. The target simulating the leading edge of a turbine airfoil is preheated and cooled by jets of different impingement tubes at various flowrates and distances. The Lumped-Capacity method is used to determine the cooling rate 'of the aluminium target and the mean heat transfer coefficients which are in turn correlated indimensionless parameters. With the aid of a computer the relation between Nusselt Numbers and Reynolds Numbers including three dimensionless geometrical parametersis correlated in a generalizd expression Satisfactory results are obtained when the Nussult Numbers calculated from the recommended expression are compared with those by experiments. The recommended expression is further compared with the correlated formula of Arizona State University by Metzger and those of University of Cincinnati by Ravuri and Tabakoff together with the experimental data and it is found that the expression correlated by this paper is more or less reasonable.

本文用六种冲击管对两种尺寸的铝质试验件进行冲击冷却实验。模拟叶片前缘的试验件予先加热,然后由不同的冲击管喷出的射流在不同的流量和距离下对它进行冲击冷却。采用集总热容法来确定铝块的冷却率从而算出冲击平均换热系数,并整理成准则形式。通过计算机的运算得出Nu数与R6数以及三种无因次几何参数的统一的准则关系式。用该式计算出来的Nu数同本文实验测得的Nu数进行了比较,取得比较满意的结果。最后用该式与美国亚利桑那州大学的梅茨格公式和辛辛那提大学的拉维利——塔巴戈夫公式同本文实验数据进行了比较,认为本文整理出来的公式是比较合理的。

In this paper an analysis of the mechanism of condensation about the effects of surface tension is described and two dimensionless quantities β_σ and β_c are proposed to characerize these effeets. Besides, another configuration size factor...

The results of our experiments on the heat transfer coefficient for the condensation of Freon 12 and 113 on four kinds of low-finned tube are quite different from those calculated by the current formula suggested by Katz et al. both quantitatively and qualitatively. In this paper an analysis of the mechanism of condensation about the effects of surface tension is described and two dimensionless quantities β_σ and β_c are proposed to characerize these effeets. Besides, another configuration size factor β_v is also considered. Based on our experiment and the theory of similarity, a new criterial equation of heat transfer for the condensation of Freon vapors on a low-finned horizontal tube is recommended as follows
