Fuselage Types.

The different types or methods of construction may be classified in the following order:—

1. Box-girder of four longerons or rails, with cross-struts and wire bracing ([Fig. 65]).

2. Tail portion of longerons, struts and wiring; in the front portion the wire bracing is dispensed with, being replaced by diagonal wood bracing, to which is screwed either three-ply or sheet aluminium alloy ([Fig. 66]).

3. In this case wire bracing is entirely dispensed with, the four, and occasionally six, longitudinals being connected together by cross struts or formers cut to the required shape, the whole body being covered with three-ply.

4. Laminated or monocoque type, formed by layers of wood and fabric, crossed alternately and glued together.
