HX-1 Circular Wing Experiment. Or what happens when I fuse the Normandy with a Corellian Corvette.

Lol I'm surprised to hear B9 wings aren't generating lift. Mine must be powered by magic or something. I kind of forgot B9 is supposed to only play nice with FAR but then it flew beyond expectations the first time and I left it as it is.

The stockification is looking good! I'm surprised the big aeroplane wings can be swept back so far, and they're just the right size for this application. There's that funny right angle at the lower leading edge of the circular section though - maybe Bill needs to take a file for final fit and finish

How is the takeoff speed using stock parts? With B9 (Somehow without FAR) it takes off very easily right where the control tower is. If your takeoff distance is close we can estimate roughly the same lift/drag ratio. In the original config the plane is a bit of a pig at low altitude but starts to break the sound barrier on turboramjets in a steady climb above 8,000m.

Well, here's some pictures of the completed wing:

The drag is much higher than B9, I think. It takes off at the end of the runway, where it pitches up madly, then levels out and flies OK. It flies slowly, but gains speed at a 15 degree climb, it wants to pitch up more that that, but then as it climbs, it has to pull up more. After a while, it stopped climbing, but continued to gain speed. I quit, and now will try to add more control surfaces.

Wait, this isn't a SSTO? No wonder I've had so much trouble with orbiting it.

I'm pretty sure I could make it into one...

Rune. It actually seems to have too much fuel!

OMG

That does look brilliant. I'll see about making some small changes to the wings to see if I can damp out the pitch up moment - alternatively, in the original craft I had the very large control surface under the engines to act as flaps, damping out the initial pitch control issue right after takeoff. (that part that looks like a Space Shuttle engine heatshield). This flap is then retracted to its normal position for the rest of the way.

As for SSTO capability - well the craft did reach space with the B9 wings, but it wasn't actually intended to (Airplane disaster movie depicting a suborbital airliner stuck in orbit, anyone?)

I do kind of like to expand the flight envelope incrementally, and thus intended to defer further flight testing once I got to the point where I had a 140km apoapsis and enough fuel to circularize.

Thanks for taking the time to model this in stock again. I do note the ridiculously complex curvature of the upper airfoils require a lot of fudging around to get right!

Thank you! I had some trouble with the upper wing, it's a bit high and long, but overall, your B9 shapes were surprisingly like stock shapes.

Oh, yeah: You've got to call the stock version the Artemis: FOWL (Fully Optimized for Wholly vanilLa installs)

I will be coming back to the Artemis soon - Today I helped a forumer redesign his X-Com Skyranger replica. Many changes were made to 2k Games' rendition of the Skyranger, in order to reduce drag and to adhere to stock KSP parts.
