Presumably you have applied for patents.

Patents are too expensive. I just need to make them public to be able to use’em after someone else has patented them.

16kts?

Well, on that note, as they , I’m out.

Best of luck in the future but there is perhaps a reason why this sort thing hasn’t been at looked before.

Right..there would be no NTSB investigations after the crash that takes place at 18-20 kts speed.

But it still goes near the speed of sound at high …tracks the sun from east to west !

So if the max speed is 27kts, what is the stall speed?

STALL IS AT 28-32 KM/H DEPENDING OF THE CREW. Oooops caps lock on.

But the CAA i doubt will get involved with that 🙂

Right if the dinner table or bed isn’t in the 180 seater passenger plane.

Oh you can die at low speed and low height

Right you can even die at dinner table or in bed. Hopefully not.

Interesting that according to Wiki it used 560kW engine rather more than your design.

128m span!. There isn’t an airfield on the planet that wil be able to accomodate it! Maybe you should think of a seaplane.

I have a 1/5 scale model here…and other to carry payload to orbit…two different things…same problem with LauncherOne..luckily the craft ( Solar Eagle ) takes off after 100 meter dash.

Caproni has huge drag…and same wing area as my model…so it is an interesting comparison…my craft wing loading is 1/6th of the Caproni. Power is 1/10th….I’d say the drag 1/10th in my craft..I should calculate it..I found no 3-views of the Caproni.

I hope you are doing more than assuming a speed of 200km/h at sea level!

I see lots of schematics showing great span but what are the penalties in drag for all this wing / fuselage area; the surface area (not just frontal area) will surely be a source of much drag (especially at high speed)?

Some of your earlier schematics mentioned some quite high g-limits. How are you calculating these g-limits for very large spans? A wing that is twice the span will weigh much more than twice as much.

There is program to calculate the stresses.

I figure the speed with the other calculator.

At high the fuselage drag is almost non existent..parasitic drag I mean..due to low density, low viscosity..and its nature.

The fuselage profile is thinner than the wing.

The high speed only happens if the plane has been able to recharge the batteries in thermal before 200 km/h speed at low.
