The paper considers the operation of electrical filter with settling electrode. To improve the operation efficiency, settling electrode is executed in the form of continuously rotating endless belt. The mathematical model of electrical filter with rotatory settling electrode is performed. The virtual model of electrical filter was made in Blender program. It will enable to visualize the process of the settlement of the particles, charged from the corona-forming plates to settle them at the electrode.

Traditionally, on the initial design stage of rocket and artillery systems are used simplified analytical techniques for the aerodynamic calculations with the adjustment of the drag-function standard for form factor or the calculation with using algebraic formulas proposed by Dorodnitsin, Krasnov and etc. However, these techniques, adapted for ranges of transonic and supersonic speeds, are give unreasonably low accuracy for the subsonic range. We have studied the possibility of using existing software packages for example, ANSYS CFX to the modeling of aerodynamics differential equations in partial derivatives in finite difference form. On the test case – the American standard form ARROW shown that the calculations in ANSYS CFX were generally in line with those ARROW using the theory of turbulence k-ε. The discrepancy at M < 0.4 is extremely small and does not exceed one percent. In the range of M = 0.4...1.0 discrepancy increases, but also does not exceed 5...10%, due to the need to select other add-ons ANSYS to calculate the wave resistance. For comparison, the function cx (M) is calculated on the existing analytical dependencies. Error calculation increases of M and reaches several hundred percent! Probably, this effect is associated with problems of application for the low-velocity of Dorodnitsin's formula for calculating resistance.
