The Importance of Thermal Modes of Astrophysical Instruments in Solving Problems of Extra-Atmospheric Astronomy
Autor: N. P. Semena
Publikováno v: Cosmic Research. 56:293-305
An analytical review of the systems for ensuring the thermal mode of current and prospective space astrophysical instruments has been performed, which showed that, in order to solve most of the current important problems of extra-atmospheric astronom

The use of scale models in ground tests reproducing heat transfer in space
Autor: N. P. Semena
Publikováno v: Thermophysics and Aeromechanics. 21:45-55
It is suggested to use the method of experimental investigation of temperature conditions at the spacecraft with application of their reduced thermal models based on the similarity criteria formulated under the assumption of the mathematical nodal mo

The features of application of thermoelectric converters in spacecraft systems of temperature control
Autor: N. P. Semena
Publikováno v: Thermophysics and Aeromechanics. 20:211-222
Modelling results on characteristics of the cooling system, which combines the Peltier element with the radiatoremitter, are presented in the paper. Despite wide application of Peltier elements, characteristics of this system are hardly studied since

Determination of spacecraft orientation by the temperature field analysis of its outer surface
Autor: N. P. Semena
Publikováno v: Thermophysics and Aeromechanics. 16:129-140
It was demonstrated that by analysing temperature field of the outer surface of the spacecraft it is possible to determine its orientation — directions to the principal heat sources within the Solar system, including the Sun and the nearest planets

Methods for creating the self-regulating mechanisms of passive systems for ensuring thermal regime of devices for space application
Autor: A. A. Konovalov, N. P. Semena
Publikováno v: Thermophysics and Aeromechanics. 14:81-91
The passive systems for ensuring the thermal regime of space objects, which are in current use, can preserve the temperature at the same level only under a certain orientation of spacecraft and at a constant heat release of the equipment. At a variab

Using PCB layout for maintenance of a thermal mode in very large-scale integrated circuits of space-application electronic blocks
Autor: N. P. Semena, A. A. Konovalov
Publikováno v: Thermophysics and Aeromechanics. 13:103-110
The paper deals with a problem of using modern very large-scale integration circuits developed for space applications and penalized with a high heat power. The method was developed for integration of cooling elements into printed fiberglass boards fo
