Looking for historical structural drawings/data on conversions from single engine to mounting on the previously single engine airplane wing i.e: Twin Sea Bee conversion and early Twin Beech (not sure on this one).
Wing under consideration is the Highlander, an aircraft close to a modern Super Cub configuration but, with side by side seating. Engines would be 80 to 120 HP each, to give desireable STOL power & wing loading values and possible single engine emergency takeoff cababilities to the highlift airfoil carrying about ~1800# GW, on inflatable Full Lotus amphib floats.
Initial concept is doubling of and extending two steel wing ribs for both left and right engine mount for each engine (4 total) sandwiching them and bolting and/or welding together to form a laminate attaching to the main spar and aft spar for each L & R mount, ideally without any alteration to either stock spar.
Wing structure to be mounted is shown here: http://www.riocreekairport.com/escapade2.htm
Any input would be appreciated. Thanks in advance.
