Micromaps host Satellite Design Proposal
After all necessary structural analysis is performed to determine
dimensions of the structure
, the type of structural configuration is chosen.
, increasing thickness increases buckling strength of a structure. However, this directly conflicts with minimizing mass. A more effective way to strengthen and stiffen a bus structure is to use isogrid construction. Isogrid consists of machining a plate of material
into a triangular pattern
, as shown in Figure 5. This option is lighter than pure aluminum
for smaller bus structures
, with identical strength properties in all load directions.
is the proposed structure type
, wall thickness must be increased to 3 mm to allow for
ease in machining the isogrid
adequate web strength
, and a skin thick enough to support solar cells.
