The trajectory consists of line segments and circular arcs.
      
"Extremal" nozzles designed by variational methods in the absence/presence of internal shocks (I), so-called "truncated" nozzles with a uniform characteristic (II), and nozzles designed by the method of conjugate circular arcs (III) are considered.
      
The thrust characteristics of nozzles designed by the method of conjugate circular arcs for both inviscid and viscous flow are inferior to those of extremal nozzles by 0.7-1%.
      
The end field is formed with the help of wire sections in the form of straight lines and circular arcs, which permits an accurate control of geometrical dimensions.

In tab. 4 and 5 are given the deflection formulas of circular beam (with one end fixed) under the action of centrifugal inertia load during rotation. Proofs of fundamental equations are given in appendix. The formulas are directly used to calculate the deflection of flyer leg in rotation. The formulas may also be applied to statically indeterminate problems such as the determination of the stresses in a card cylinder lying flat on ground.

In writing the equations of motion of the railway vehicles,the relatingequations of the coordinates of a wheelset and the expressions of thegeometric contact parameters are required.The forms of the publishedformulas are numerous,and some them appear to be incorrect.In thiswork,the exact formulas were derived first,then approximate ones.For the the symmetric wheelsets with conical tires,it performed withoutgreat difficulties.For the wheelsets with circular wheel prefiles,thoughthe simultaneous equations in the general case are presented,the explicitsolutions for rolling and for yawing are derived separately.

在建立铁路车辆的运动微分方程时,需要用到轮对各个坐标之间的关系及各个几何接触参数。原有的文献公式形式众多,有些看来是错的。本文先推导精确公式,然后得出近似公式。对于对称锥形轮对,问题可以完全解决。对于圆弧踏面轮对,本文列出了一般情况下的联立方程,但只得出了仅有侧滚及仅有摇头角位移时的显式解。算例表明,只有圆锥踏面轮对对于侧摆位移的各个几何接触量的线性公式才与精确公式比较接近。所有的等效斜度,重力刚度和其它情况下的几何接触量的原有文献近似公式大都有比较明显的误差。
