Project summary

Lavochkin Association has more than 30 years experience in developing, manufacturing, testing and operating of the spacecrafts (SC). During that period big practical and scientific-technical experience was collected, cooperation with firms-subcontractors, having high-qualified specialists staff and unique theoretical and experimental base, was established.

Industrial possibilities of Lavochkin Association permit to conduct a complete cycle of development, manufacturing, ground and flight testing for separate units and gears, as well as for the whole spacecraft.

State Enterprise "Krasnaya Zvezda" is parent enterprise in Russia in the field of studies, development and manufacturing of space nuclear power plant (NPP), leading specialists of which as a staff of STC "Energocosmos" perform development of various types of NPP during more than 30 years using scientific and experimental investigations on heat engineering, thermionic energy conversion and space nuclear power engineering.

Scientific Research Institute of Applied Mechanics and Electrodynamics, created in 1987, is the leading scientific institute in elaboration and using of electric rocket thrusters (ERT), works of which are based on investigations according two main scientific directions:

- applied mechanics, connected with research and elaboration of space ERT;
- applied plasma electrodynamics, including problems of interaction with electromagnetic radiation and radioelectronic systems functioning while the presence of artificial plasma objects.

Purpose of the project is layout elaboration of geostationary communication satellite with transport and power module on the base of ERT and perspective power plants, providing launch of SC into point of staying, supporting of its work on further stages, taking into account features and requirements to SC components and estimations of expenditures on their creation and exploitation.

Results of works will be based on experience of space technic sample creation, design-calculative investigations and results of experimental development, system approach to design-structural decision accepting.

As a result of works on the project variants of perspective design-structural decisions of geostationary communication satellites creation and their TPM, based on ERT and perspective power plants, and also analysis of existing technical decisions will be presented.

Reporting materials will preliminary include

- Observation of creation and exploitation experience of geostationary communication satellites, based on traditional analysis of design-structural decisions of geostationary communication satellites and their parts creation, including launch vehicles.
- Analysis of special features and requirements imposed for perspective geostationary communication satellites and their components.
- Analysis of the different launching schemes of geostationary communication satellites into the point of staying and their support during exploitation period while using of perspective propulsion and power modules and different launch devices, taking into account necessity of spacecraft removing from the orbit after finishing of its exploitation
- Design-structural investigations and optimization of power-supply systems parameters, determination of rational spheres of using of traditional and alternative power supply sources.
- Comparative analysis and peculiarities of using chemical and electric rocket thrusters on geostationary communication satellites, issues of ground elaboration and operation. Generalization of the results of theoretical, calculation and experimental studies of SNPS functional capabilities conformably to the task considered.
- Development and design decisions and parameter optimization by complexation of propulsion and power modules for geostationary communication satellites. Analysis of special features by NPP operation at spacecrafts and effect of reactor radiation to spacecraft operational characteristics. Explaining of nuclear power sources using safety in space according to international rights and standards.
- Complex system analysis of functional possibilities of perspective geostationary satellites on the stages of exploitation in the combination with the ground segment. Analysis of perspectives of using of TPM for putting onto the orbit of the different payload types.
- Economic analysis and effectiveness evaluation of geostationary communication satellites by using nuclear and solar power plants and electric stationary plasma thrusters.

Structural schemes and power supply propulsion systems design methodologies, optimization questions of SC components mass-dimensional parameters and electrical power, questions of satellite resource providing will be described in the report. System criteria of comparison, estimation, optimal design solutions and expenditures structure for mission realization will be shown. Estimations of geostationary communication satellite components working at the ground, during tests and in the environment of real spaceflight will be submitted.

The realization of work under the project is supposed with participation foreign collaborators. The experts of concern "Finmechanica", firm Alenia Spacio (Italy) and DASA-Munich (Germany) will participate realization of some joint accounts and analysis of results of work, as well as in exchange by the information and in working meetings during fulfillment of the project.
