Excellent sketch mate, you should consider getting stuck into A.TT (have I hinted too much already? Lol)
This is the MS Paint graphic I got when I put your previous description to my artist:
I must admit I can’t guess what would happen aerodynamically at the wingtips. As you suggest, it would be handy if a harpoint could be incorporated
into the wingtip connector for tip-tanks or even ALARM/Brimstone. The interface between the two wings seems to be the complication to all these
Given the TVC and no pilot (fewer g-limits) it could be very maneuverable (weapons tolerances allowing) but I can’t imagine the upper wing have
anything like the control efficiency of an all-moving canard –although it could have slats and flaps for take-off/landing.
Provided the lower wing retains the benefits of FSW in terms of low stalling speeds, then this looks like it would be better for lift than the pure
What do they call these wings? –Compound wings? Coupled wings?
This is an early configuration drawing but already it is looking like a serious contender to the FSW design –hard to say which is better.
The aft extensions with control surfaces (elevators????) that you drew should definitely become a feature.
I think that we are using a bigger lift jet than we need –both designs (D-0013 and this one, D-0014) could benefit equally from a smaller lift jet
in the 3-4000 lbst range.
Where this design is suffering is internal fuel. With the shoulder tanks the FSW design easily achieved the 10,000 lb spec regardless of the fuel
density you chose. This one is, I guess, currently in the 8,000lb range (given fuel in the upper wing).
We could christen this diamond wing-plan “Lucy” (Beatles fan, not druggy)
-back to basics, here’s another similar and increasingly discussed wing plan:
As you can see it is generally associated with airliners. My gut feeling is that this doesn’t suit a strike aircraft but obviously I’m no expert.
And here’s a concept drawing for a diamond-wing stealth UAV (USAF):
I think that’s a bit far out for us.
