6 FAQs about [Analytical modeling of spacecraft power systems]
What is the simulation model of spacecraft power system?
Based on the graphic modeling function of Modelica, the simulation model of Solar array, nickel-hydrogen battery group and power control equipment components is established, and the multi-domain simulation model of spacecraft power system is obtained according to the topological structure of the power system.
Can a dynamic modeling approach be used to model a spacecraft?
4. Conclusions A dynamic modeling approach has been described to obtain an analytical model for a spacecraft with large solar arrays and deployable antenna.
What are some examples of space power supplies?
Spacecraft power supplies; space stations, space power reactors, solar arrays, thermoelectric generators, energy storage, and communication satellites are among the topics discussed. Work of the US Gov. Public Use Permitted.
Why do spacecraft need solar wings & deployable antennas?
Thus the required spacecraft often need installation of solar wings and deployable antennas. A large deployable antenna structure is widely used to increase the gain of the space-borne antenna [ 1 ]. In 2000, the United States successfully launched the commercial communications satellite Thuraya with a 12.25-m aperture and 55 kg mass [ 2 ].
How can vibration data be used to simulate flexible solar panels?
Based on experimental methods [ 15, 16, 17, 18 ], Sabatini et al. [ 16] used a vibration data acquisition method based on image technology to simulate highly flexible solar panels using aluminum sheets for identifying the vibration modes and characteristic frequencies of spacecraft’s flexible structures.
How many elements are in a spacecraft?
The parameters of the spacecraft. For the finite element model, the solar arrays, the main-body, the deployable arm, and the deployable antenna are modeled by the BEAM 188 element, the SOLID 45 element, the PIPE 16 element, and the SOLID 45 element, respectively. The flexible spacecraft is divided into 12,892 elements.
