SPACE PLATFORM

This invention relates to rocket and space industry and is used in the production of spacecrafts (SC) of non-airtight version by modular principle. The space platform (SP) is a structurally and functionally separated module of SC combining service subsystems providing the operation of a payload module. The base of SP is the primary structure of body (PSB), on which an instrument compartment is located, wherein the end faces of PSB protrude beyond the planes of instrument compartment panels. On the end faces of PSB, there are docking points with a separation system, inside PSB there are propellant storage tanks. The instrument compartment is made in the form of a rectangular parallelepiped formed of panels, whereas some of them are radiator panels. The devices and equipment of service systems are located inside and outside the instrument compartment. The parts mounted outside on the instrument compartment: correction engines, orientation engines, docking points with payload, rotary wings of solar panel (SB) folded in start condition and fixed to rotatory devices symmetrically on two opposite sides of the instrument compartment with use of bars, whereas the SB wings are made in the form of flat panels attached to each other. Orbit raising engines can be also located on the instrument compartment. The technical results ensured by the above mentioned set of features are weight reduction; increasing the packaging density of spacecraft created on the basis of this SP; reduction of the scope and time for the works for adaptation of launch vehicle; improvement of technical and performance specifications; possibility of simultaneous launch of several SCs created on the basis of this SP; reduction of the time and cost of SC production. Данное изобретение относится к ракетно-космической отрасли и применяется при производстве космических аппаратов (КА) негерметичного исполнения по модульному принципу. Космическая платформа (КП) - конструктивно и функционально обособленный модуль КА, объединяющий служебные подсистемы, обеспечивающие работу модуля полезной нагрузки. Основой КП является силовая конструкция корпуса (СКК), на которой размещен приборный отсек, при этом торцы СКК выступают за плоскости панелей приборного отсека. На торцах СКК размещены узлы стыковки с системой отделения, внутри СКК расположены баки хранения рабочего тела. Приборный отсек выполнен в виде прямоугольного параллелепипеда, образованного из панелей, причем некоторые из них являются панелями-радиат
