UAV,s and aircraft are favourites for 3d modellers..Wouldnt be hard to grab a model online,scale it to full size the slice and dice to flesh out all
the technical details internally.CAD Monkeys are a lazy lot LOL..
Eh, no need to reinvent the wheel. Loiter time is important, but not speed: it's going to have high aspect ratio wings. It's going to be as small and
light as possible. Only so many configurations you can chose from for similar requirements.
As someone noted the ventral intake is interesting given the Russians preference for operability off rough fields.
Not really. Normally you could guess better flow at AoA and cleaner air, but with the sensor ball or other payloads in front of it I'm not sure the
later is true, and the former is clearly not a requirement/need. It could be simply something like the way the engine has to sit to put thrust through
the centerline, this arrangement lends itself more cleanly or easier/lighter to brace/mount, or it gives slightly better clearance enabling a slightly
bigger prop or shorter gear (and shorter gear means less weight, more available volume, etc). Or the guy at Kronstadt was told to put it down there
so it looks less like a Reaper.
