Andrienko A. Ya., Chadaev A. I. Principles action of control system by passive returning to the Earth of space vehicles


With reference to a problem of increase of safety of orbital flights control principles by passive returning to the Earth space objects - on the basis terminal control of a flexible (cable) sheaf are analyzed. The offered algorithm of control of a sheaf is based on the minimum information on a current condition of a sheaf (from gauges of force of a tension and length of the part of a cable winded from the coil) and allows to deliver space object to the Earth at comprehensible to weight of a cable and duration of operation of returning.

Keywords: terminal control, safety of orbital flights, passive returning to the Earth, cable connections.



Arbuzov V. P., Larkin S. E., Lukjanovez O. A., Mishina M. A. Measurings chains of capacity sensors with the temporal division of channels


In clause the reasons of occurrence of an error in measuring circuits of capacitor gauges with switching channels are analysed. It is offered to provide an invariance of factors of a negative feedback for indemnification of an error as from nonideality used for transformation of capacity of the gauge to a pressure of the operational amplifier, and presence of capacity of a cable of communication. The calculated value of an error from nonideality the used scheme of comparison in all dynamic range of change of controllable physical parameter has not exceeded 0,045 %.

Keywords: transforming error, correction of error, measuring circuit, temporary division channels.

Polyakov A. V. Measurement of oxygen concentration by fiber-optical recirculation sensor


The design of the quasi-distributed measuring device intended for determine of oxygen concentration is offered. Sensitive elements are section of the optical fiber, rigidly connected with ferromagnetic strips. The measurement principle is based on magnetostriction effect, leading change of length and a refraction index of a fiber, and consequently, to change of recirculation frequency. The control of concentration is carried out in several space points on various wavelengths. The measurement error of concentration amounts units of percent.

Key words: quasi-distributed fiber-optical sensor, oxygen concentration, recirculation frequency, magnetostrictive effect.
