That’s not just Kyie to Moscow… That’s like Kyiv to Edinburgh Scotland!
Obviously everyone would prefer them heading in the direction of Russia, not Scotland!
I mentioned before about using the Burt Rutan Long Ez [https://en.wikipedia.org/wiki/Rutan_Long-EZ](https://en.wikipedia.org/wiki/Rutan_Long-EZ) could get us 3000km ranges with useful payload.
And it’s far from optimal.
The design though has certain requirements. You want speed at low power to get range if you prefer to cover a lot of the journey under nightfall.
And that requires a lot of improvement in aerodynamics.
Design starting points were pusher propeller, high or low wing mounting using a custom engineered single wing which doesn’t require a heavy O ring, they went low wing and I went high wing with my suggestion. A 2 stroke diesel is potentially ideal for high power to weight and high efficiency. I guess they are using this. The wing in their design is high aspect ratio also, and likewise appears to have little no control surfaces which greatly improves aerodynamics, so they seem to use a v tail for such control. The picture available did not show it but it’s typical on drone design and the current fashion.
I consider in my concept design that it may use front canard as control surfaces but sought to remove at least some tail surfaces if not.
Other aero features is smooth wing root curved attachments, which reduces interference drag. Their design seems to have this too.
CFD analyses has shown that the Long Ez can be improved by curving the wing tip route with significant reductions in drag.
These are also used as rudder so are quite large. Reducing these to simple wing tip devices would require the conventional rudder, or wing flaps, but in my concept are replaced altogether using small wing tip propellers to provide yaw. These would be powered off a turbo expander running off the engine exhaust. This is a somewhat exotic concept though and would push up cost, although not by that much. Efficiency can be boosted quite a lot but it would hinge on the weight and affordability of motors. Compounding like this can also reduce noise.
But either way, the approaches are similar except that the rudder or canard control and in the case of the Ez, there is no tail rudder so it would need either a wing tip mounted rudder or wing flaps to brake on one side, or a rudder placed before the pusher prop. This can include one pointing down below the fuselage and the combination gives roll as well.
Very nice! Keep going Ukraine.
Please say the test was levelling one of Putin’s mansions.
Military targets far-far away go boom. Hope to see the results soon.
Holy shit.
Quad-coptor drone or one with an actual rocket engine?
Does Ukraine have a missile that can drop from significant altitude and avoid EW? Rather than the style that cruise along and need guidance all the way?

Drone or Cruise Missile?
The fact the lines are getting blurred is insane!
Wasn’t it 1000 km few days ago?
Go get em
>3,000-kilometer
I’ve just realised how far that is…

What is the distance to Florida from Ukraine….
Murmansk is now in range.
