Double wavelength speckle interferometer for the research of static deformations of gas turbine engine parts

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
Two coherent radiation sources with the wavelength of 532 nm and 632.8 nm are used in a speckle interferometer optical arrangement with combined beams and speckle-modulated background wave. The reference beam is formed with the help of a diffuser located

A robust computational approach for Zakharov-Kuznetsov equations of ion-acoustic waves in a magnetized plasma via the Shehu transform

Journal of Ocean Engineering and Science, 2023
The application of the q-homotopy analysis Shehu transform method (q-HAShTM) to discover the estimated solution of fractional Zakharov-Kuznetsov equations is investigated in this study.

Modified homotopy methods for generalized fractional perturbed Zakharov–Kuznetsov equation in dusty plasma

, 2021
We propose a new modification of homotopy perturbation method (HPM) called the δ -homotopy perturbation transform method ( δ -HPTM). This modification consists of the Laplace transform method, HPM, and a control parameter δ .

Symmetry analysis and conservation laws of a further modified 3D Zakharov-Kuznetsov equation

Results in Physics, 2020
We study a further modified (3 + 1)-dimensional(3D) Zakharov-Kuznetsov equation. The classical Lie symmetry method will be employed to obtain solutions of a further modified 3D Zakharov-Kuznetsov equation.

Using signals from the gas-turbine engine shaft speed sensor in the diagnosis of the technical condition of its reduction gearbox

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2020
It is shown that analyzing the signals from standard sensors of gas-turbine engine shaft speed we can resolve some issues of diagnostics of the technical condition of the reduction gearbox without installing any additional vibration transducers.

On the One Class of Hyperbolic Systems [PDF]

, 2006
The classification problem is solved for some type of nonlinear lattices. These lattices are closely related to the lattices of Ruijsenaars-Toda type and define the Backlund auto-transformations for the class of two-component hyperbolic systems.Comment ...

Reduced Differential Transform Method for (2+1) Dimensional type of the Zakharov-Kuznetsov ZK(n,n) Equations

, 2014
In this paper, reduced differential transform method (RDTM) is employed to approximate the solutions of (2+1) dimensional type of the Zakharov-Kuznetsov partial differential equations. We apply these method to two examples.
