Sensitive elements of basic direction «East - West» with oscillating mass for a gravitational-inertial compass

Manufacturing of devices for tool orientation based on action of Koriolis force on mass which oscillates along the vertical of a place is considered. Possibility of technical realization of sensitive elements of a gravitational-inertial compass on the basis of the orientation mechanism of alive organisms is shown

The principle of gravity-inertial orientation

The important problem of gyrocompass without drift creation is considered in this article. The designing device allows to define the accurate information about mobile and stationary objects orientation in the case of long-term (months, years) absence of the determining the cardinal direction possibility. This article focuses on the idea of gyrocompass without drift creation, which works on the principle of gravity-inertial orientation at the theoretical level

Integrated approach of the dynamic characteristics optimization for spacecraft’s technical systems on the exploratory tests

Integrated approach is the process connecting various project, theoretical and testing procedures. It is provided by the specific series-parallel combination of the mentioned operations. This paper shows that using results of the previous procedures on the further algorithm stages of exploratory tests and product verification is expedient. At that, the necessary correcting of engineering solutions in corresponding procedures is conducted simultaneously. Then, results of each procedure are used in the fixed sequence. It provides maximum attainable optimality of the designed system

Comparative physical-tribological properties of anti-friction ion-plasma Ti-C-Mo-S coating on VT6 alloy or 20X13 and 40X steels

Results of comparative tests mechanical and tribological properties of solid antifriction Ti-C-Mo-S coating, deposited by magnetron-plasma combined sputtering method on substrates of VT6 titanium alloy, 40X and 20X13 hardened steels are provided. Coating is sputtered using the same conditions and technological regimes on substrates of different materials. However, the friction tests results showed significant difference in tribological characteristics of coating depending on type of material used for substrate, first of all by wear-resistance ability. Authors suppose that this is due to difference between physical properties such as composition and structure of substrate materials that determines hardness and coating adhesion to surface
