5. ASSEMBLIES Basic Construction

Aluminum Skin

Basic construction of the shelter is composed of scavenged C-46 formers (1) attached to fore wing spars (2) which sit on two pairs of horizontally opposed wing ribs (3). Plywood flooring (4), also scavenged, is lashed to the wing spars. Formers are laterally braced by rope and/ or aircraft cable (5) during construction, until lapped aluminum skin (6) is secured (see next page).

Scavenged aluminum skin forms the outer layer of the double-skin envelope of the initial shelter iteration. This alumimum sheathing does double duty as a rain screen when horizontally lapped (as above). Sheathing starts at the bottom as in traditional shingling, or could be attached at the apex of the former and released if connected by rope or cable. Aluminum has many advantages in this type of construction, including corrosion resistance, light weight (about 1 lb per 2 sq.ft. of airplane sheathing), and workability. Its disadvantages are thermal bridging and susceptibility to stress fractures.
