FILM-TYPE RADIATION REFLECTOR Russian patent published in 2003 - IPC

FIELD: space communications. SUBSTANCE: reflector has external pneumatic chamber and radial posts in the form of flexible tubes with holes to receive interacting pneumatic cells communicating with internal chamber and filler source and also interacting with mirror sheet. In addition inner spaces of flexible tubes accommodate solid-state tubes with holes coaxial to those of flexible tubes and used to provide communication between inner spaces of adjacent pneumatic cells. Nipples in the form of flexible cylindrical fittings are installed on external side of flexible tube above its holes. External pneumatic chamber and radial posts of film-type radiation reflector may have cylindrical boots enclosing pneumatic cells on outside which are divided by diaphragms at junction points of pneumatic cells. Filler source of film-type radiation reflector may be made in the form of foam-producing dielectric source or in the form of electricity conducting liquid source with emf sources connected through switches to operating mechanisms immersed in conducting liquid. EFFECT: enhanced reliability due to retaining functional abilities of pneumatic cells in case of their depressurization. 5 cl, 5 dwg
