Polyhedral rotorcraft modules for modular aircraft

A method comprising:

• rigidly coupling at least a first adjacent aircraft module to a second adjacent aircraft module to form a modular aircraft;
• wherein:
• each aircraft module comprises:
• a regular dodecahedral cage structure having regular pentagon faces, each of the regular pentagon faces lying in a different plane one from another, each of the regular pentagon faces having five sequential edges and five vertices forming a complete loop defining the regular pentagon face, each pair of adjacent sequential edges connected at a common single vertex from among the five vertices and forming an interior angle of 108°;
• a single, fixed-pitched propeller with an axis of rotation;
• and
• a motor configured to drive the propeller;
• rigidly coupling comprises attaching one of the regular pentagon faces of the first adjacent aircraft module to one of the regular pentagon faces of the second adjacent aircraft module;
• the attached regular pentagon faces of the adjacent aircraft modules lie in the same plane;
• and
• the attached regular pentagon faces of the adjacent aircraft modules are in one of two relative alignments, a first alignment in which all five vertices of each regular pentagon face coincide exactly, or a second alignment in which only two of the five vertices of each regular pentagon face coincide exactly.
