To date, ISS-Reshetnev Company has amassed solid expertise producing honeycomb structures for satellites. Since 2000 this technology has been flight qualified aboard all ISS-Reshetnev’s satellites.
Typical qualified solutions that the company is able to offer in this sphere involve a range of typical honeycomb cores and face sheets, embedded parts, installation of heat pipes and liquid loops on the inner or the outer side of the panel, assembling of a wide range of elements, for instance, optical solar reflectors, flat electric heaters, fasteners of the VELCRO type, etc.
Main technical specifications of honeycomb panels developed by ISS-Reshetnev:
|Honeycomb panel face sheet||В95 Aluminum alloy||Carbon fiber|
|Face sheet thickness||0.3…0.8 mm||0,32; 0,48; 0,64; 0,8; 0,96 mm|
|Honeycomb panel thickness||8…150 mm||10…60 mm|
|Honeycomb panel size, max||5800 x 3000 mm|
|Honeycomb core||Material: aluminum foil 20, 23, 40 microns thick; perforated
Cells: hexagon; cell size: 2.5; 3.5; 6 mm
At ISS-Reshetnev Company the most advanced and powerful software solutions like CATIA v5, NASTRAN and THERMICA are used to design satellite structures and perform mechanical and thermal design and analysis.
The Reshetnev Company runs the complete production cycle of honeycomb panels with the annual capacity of 500 m2.
Honeycomb panels (as part of satellite structures and separately) undergo the whole cycle of qualification and acceptance tests. These include mechanical tests (static, dynamic, acoustic), degassing and thermal cycling, as well as controlling geometric parameters of honeycomb panels with the help of automatic inspection and measuring machines.
A structure of satellites based on Express-1000 and Express-2000 platforms is made using the modular approach “payload – platform”. In addition to honeycomb panels, it also includes a load bearing structure – a central tube and a conical adapter made from high-modulus carbon fiber.
