Annotation: The paper deals with the advantages and peculiarities of operation of a device for soft separation of spacecraft from launch vehicle.

Annotation: The description of the program and its work on the part of the user is given as well as a description of the software automation solution from the programmer’s side. The introduction of an automated program has significantly accelerated the process of attestation of climatic chambers.

Annotation: The analysis is presented of measurement uncertainties components by A and B types during metrological certification of measuring instrumentation. The example is presented of the evaluation of measurement uncertainties of pressure measurement channel. Introduction of the methodology under consideration will ensure compliance of the metrological characteristics determined with the regulations of international normative documents.

Annotation: The method not used before to measure discontinuity of working fluid using video recorders is considered. To ensure the uniformity of measurements when reducing this method to practice, the methodology of its certification experimental investigations is proposed for the purpose of determination of its applicability limits.

Annotation: Example of the estimate of the measurement error of the linear accelerations during the free fall of the kinematic model is considered. It was concluded that experiments on error measurements can be replaced with calculations for those parameters which have sufficient initial data on metrological performance of the applied instrumentation.

Annotation: Applicable documents on metrological assurance regulate the estimation of measurement uncertainty. In Ukraine there is no regulative methodology for uncertainty calculation when certificating test equipment that causes the necessity of its definition. This article offers the methodology for uncertainty calculation when certificating a centrifugal machine that is used to reproduce precisely the given value of linear acceleration that permanently acts on a tested unit spinning together with a rotor. The offered methodology for uncertainty calculation is applicable to centrifugal machines, for which numerical values of reproducible linear acceleration are determined by results of calculations of the centrifugal machine’s rotor angular velocity and radial distance from rotor’s longitudinal axis to the given point of the tested unit. Initial data used were results of observation obtained after multiple reproductions of the given values of linear acceleration as well as numerical values of errors and measurement uncertainties of measuring equipment that was used when monitoring the rotary angular velocity and radial distance considering the contribution of each measurable parameter to a certain value of linear acceleration. The calculation given in the article estimates the limit of linear accelerations that can be attributed with established probability to the given value of linear acceleration reproduced when certificating the centrifugal machine. The design formulae are given to estimate the uncertainty components of the reproducible values of linear accelerations and the recommendations are given to present the uncertainty budget.
