too flimsy looking, propeller wise. (wikipedia russian flying tank btw. lol) i like the main carriage though, it feels.... tanky in a WW1 or WW2 kinda way. the propellers arnt really time effective though, even if we ignore lift to weight ratios. they didnt have any helicopters in WWII did they? i cant recall....
I don't know, it doesnt look too flimsy propeller wise. Its hard to say because nobody has done a duoprop helo. Moeller did a few working models with six single props for his "george jetson" commuter and it isn't that different in size... Blades to OA size. A duo prop would give better efficiency of lift, but exactly how much... ?!?
Yes, though they were rudimentary at best. They were termed gyros back then. They either looked like an ultralight helicopter or like a plane with a helicopter blade on top. Sikorsky made a design that developed the helicopter into what it is today, but the Germans had the most development in helicopters. [link] This [link] had two helos propellers on either wing and is closest to the above design
Most helicopters used back then were for recon if they were used at all during the war
Well, the half rings that hold the shroud for the fan looks a little blunted. I think they should be more rounded. As far as the fan blades, the more blades there are, the stronger the effort to push (fewer means the fan propels the vehicle faster or quicker). That said, it seems you are going with a 12 blade duo-prop (meaning 24 counter-rotating blades). Duo-props (used for the last 20+ years in the marine industry) are another method of attaining strength to push (against air, water, meat-byproduct, whatever). I think it looks a little too busy. I think you could probably attain a similar look with few blades. Also, ...how is the propeller suspended in the ring???
I think the fuselage and tail section are a spot on match for a WWII vehicle, even the color is almost a spot on match for color schemes of the day, though I imagine this was just a temporary coloring for a WIP
Hey there and thanks for the huge feedback! Fewer blades sound good and the I just plainly forgot to add the suspension of them propellers...Was all made in a rush, so thanks for reminding. Now I need to chew through the rest of the comments! Thanks again!
