A main issue in high precision navigation grade accelerometers development is a provision of a zero signal and a scale factor stability and repeatability. A development and research experience for Q-flex and Si-flex compensating accelerometers allows

The paper is devoted to azimuth correction system of an inclinometer used for well drilling in high latitude areas. In these areas, ordinary types of navigation equipment (gyroscopic and magnetic sensors) are ineffective because of small horizontal c

The paper considers methods and equipment developed for measuring driving pile displacements. Traditional accelerometers and inertial techniques cannot be used because of extremely large shock loads and vibrations, and also due to economic considerat

An approach to the numerical study of three-dimensional flow past a high-speed electric train is considered, including the case of turbulent boundary layer separation. The method of viscous-inviscid interaction is used to compute the aerodynamic char
