Abstract
A time-saving approach to perform technical calculations of thermal conditions of orbital motion of 3U CubeSat nanosatellite was applied, which made it possible to make the thermal calculations of a satellite with simple structure geometry using MatLab and SolidWorks Simulation. Passive thermal regulation facilities are sufficient for a 3U CubeSat to provide thermal conductivity of the case’s structural elements and to remove heat from the lighted surface and internal components to the satellite’s shadowed surface. Application of spectrally selective coatings allows narrowing the range of surface temperatures of 3U CubeSat.
Highlights
The design of the thermal operating conditions is one of the main tasks in satellite development procedure
The procedure for calculating the nanosatellite thermal conditions consists of two parts: 1) calculating the power absorbed by the faces of a satellite performed in the MatLab environment; 2) calculating the heat transfer under structural elements of the case of a satellite and the heat dissipation in the outer space realized using the SolidWorks MCAD tool – SolidWorks Simulation
In the steady-state periodic part of the graph one can see the features of the thermal conditions associated with the shape and orientation of the satellite; in the areas of the spacecraft temperature growth, observing a bend corresponding to a decrease in insolation associated with the orientation of the satellite by a small face on the Sun
Summary
The design of the thermal operating conditions is one of the main tasks in satellite development procedure. Comprehensive ground-based tests of onboard systems as well as structural elements of satellites, computational techniques come into importance They make it possible to optimize many parameters of the device on early stages of design. In the family of software products for scientific and technical calculations, there is a tendency splice it with MCAD development environments, creating a unified MCAD development environment with numerical studies facilities. This fact is caused by desire to automate the mostly manual transfer of product geometry from a development software to a calculation program
