Abstract
An axial flow turbomachine's engine core (16) and radially outwardly disposed fan case (18) are joined together with a radially extending segmented fan case strut (10). The strut (10) is segmented into a radially inner portion (20) and a radially outer portion (20) at a midspanly disposed strut joint (14). The strut joint (14) has an axially extending tapered tongue (26) which slidably engages with a mating axially extending groove (46). A radially extending flange (36) disposed proximate to the trailing edge (35) of the inner portion (20) is bolted to the radially extending flange (56) disposed proximate to the trailing edge (55) of the outward portion (40) when the tongue (26) is fully engaged with the groove (46) to releasably secure the strut joint (14). Another embodiment shows a pair of interlocked axially extending channels (60) each having a U-shaped cross-section replacing the interlocked tongue and groove (26,46) of the first embodiment. Radially extending flanges (36,56) disposed proximate to the portions' (20,40) trailing edges 935,55) are likewise bolted together to releasably secure the strut joint (14) when the channels' three corresponding pairs of contact surfaces …
