I challenge you!

Refined config. no blending on facets yet. The wings are a bit unoriginal though. The squashed look is because I think it's important to angle the sides at greater than 45 degrees to reduce the RCS from airborne radars (AWACS etc). The knock-on effect is that the "vertical" stablizers are canted out greater than 45 degrees which reduces their control authority in jaw, meaning that they have to be bigger, and heavier.

planeman, your design is coming along quite well. Could I make a suggestion? Well, here it is: why not have the leading and trailing edges of the tails be parallel to those of the outer part of the main wings--reduces the total number of directions from which a radar signal will be reflected.

Very good question. Currently I'm toying with the idea of using radar-transparent composites for the leading, trailing and tip surfaces. The core of the wing would be faceted metal surfaces. The square cut wing/tail tips are thus composites. Note the shape of the core (darker, inside red line on plan view) which I think is in line with your suggestion(?). The advantage as I see it is improved aerodynamics. The problems are bonding the composites to the metal facets without leaving high-reflective joints. Also, I am unsure as to how radar transparent composites are - is it across all wavelengths?

Any suggestions most welcome.

Just in general, how do you do these images? Is it timeconsuming?
I mean i have few "own" aircraft ideas for my own weird projects and i was wondering if you could help me. Would you PM me if you are interested and i can give you more specific information to work on....

I use MS Paint and it would be time consuming if I wasn't so practiced. happy to help ad hoc.

It ain't pretty....

Ok, this is more like it. I've given up on the over-fuselage intake because although it lends itself to stealth, it is a pain in the ass for high angle of attack flight. This is fully faceted except the wings which have composite leading and trailing edges.

Although it might not be immediately obvious, the trailing edges of the tail fins (approximately 45 degrees outwards cant) are at the same angles as the trailing edge of the opposite wing.

I'm already thinking through a more optimum rear fuselage to completely rule out any "corner reflection" between the fuselage and the tail fin.
I've also increased the cockpit glazing. With the blended-facet deriviation the two side cockpit windows will be merged into one.

Ok, someone snapped a covert shot of my top secret prototype (lol):

I have 2 designs, both of them conversions of Mirage Delta into double delta flying wings with a flat bottom and everything on top.
The cheaper, but hard to use one (Ease was never in the requirements )

That's a great start bro, you're thinking along the right lines for sure. Without being negative, there are a couple of surfaces which would give a strong radar signiture from a side angle, i.e. the single vertical tail and the vertical sides to the cockpit in front of the intakes. They could possibly be negated by clever use of composites but it might be simpler to cleverly re-shape it.

PM me if you want to discuss making the shape stealthier.

PS. I love your solution, why didn't I think of that.
