METHOD AND EQUIPMENT FOR FORMING AND ASSEMBLING UNCURED SPARS FOR THE HORIZONTAL STABILIZERS OF AIRCRAFT

摘要

H-beam carbon-resin spars for the horizontal stabilizers of aircraft are formed by using forming devices (60) each of which comprises an elongate core (61) of rectangular cross section fixed securely to a flat plate (62) which extends around the whole of the core (61). An overhead travelling crane (10, 11) can run in a longitudinal direction and has pick-up means (16) which are vertically movable and can be turned over about a transverse axis. A flat section to be formed is placed on a first upward-facing core; the section and the first core are transferred together into a hot forming apparatus (20, 21), and a vacuum and heat are applied to deform the section on to the core, thus producing a first C-section (14). A second C-section (13) is produced in a similar way. This is turned over, using the pick-up means (16) of the overhead travelling crane, and is placed on top of the first section (14), so as to bring the webs of the two sections together in an H-beam configuration.
