Light aircraft fuselage and structural frame connectors

摘要

A structural frame or truss, suitable for use as part of a light aircraft fuselage includes steel tubular members joined by structural connectors or connector blocks. The blocks include bore holes into which the ends of lateral tubular members are inserted, and longitudinal tubes or longerons are inserted through holes extending between opposed block faces. The structural connector blocks not only connect the tubular members, but they serve as jigs for assembling the structural frame. Tubes can be plug welded to the blocks, and the fuselage outer skin can be attached to the structural connectors to form a dual fuselage structure.
