ABSTRACT:
The disclosure relates to a deployable M-braced truss structure that is efficiently packaged into a compact stowed position and expandable to an operative position at the use site. The M-braced configuration effectively separates tension-compression and shear in the structure and permits efficient structural design. Both diagonals and longerons telescope from an M-braced base unit. They are deployed either pneumatically, mechanically by springs or cables, or by powered reciprocating mechanisms. Upon full deployment, the diagonals and longerons lock into place with a simple latch mechanism.
