Will this even work? One rotor helicopter (one blade only)

Aerospace / RC
#1

I have never even flown an RC anything. So I’m new to the whole thing. But dammit, I want to make a one rotor heli, and its gonna work too, Newton be damned.

OK, but seriously, will this idea work? Why? Or y not? I have read that there is some strange inertial force applied as three phase brushless is applied. This force cancels for counter rotational blades, hence the interest.

Anybody wanna help me figure this one out? If it works I’m gonna try to sell em. I am happy to cut contributor(s) in on profits, scalable by length of time working for the production team responsible, and of course level of contribution should be considered as well.

My instinct for this business is that I believe things will go well for those involved in this project. And BTW, 3e8tech has numerous opportunities for those willing to put in the work. Here is a video discussing my hack at the thing.


Oh, and be sure to check out 3e8tech.com.

MD900/MD902

It can be done, but generating enough thrust through the tail boom (and remember, it has to be variable thrust) at the RC level is going to be really, really tough.

Do you mean no tail rotor or only one main rotor blade? No tail rotor has been done several ways in real helicopters; I think large tail rotors (i.e. not fenestrons) are an efficiency / best option thing at the moment, although I was reading a thing about maybe the fenestrons being patented so idk. Single main rotor blade is possible and theoretically more aerodynamically efficient than two, and there’s at least one youtube video with it working, but I would assume the consensus is the penalty from the counterweight beats the gain from removing the other blade’s wake.

Not exactly a controlled vehicle, but rocket powered monocopters are a thing in amateur rocketry.

Check this out

Yeah, I saw a guy working on a motor that functioned by shooting propellant from the tips of the blades. It was very very fast rpm rotation but there were issues.

But I am shooting for controlled.

Or maybe I’m just nutty…

Are you referring to the helicopter backpack with the wingtip hydrogen peroxide rockets? I know this was a concept way back when (I remember hearing about it back in middle school) but I was under the impression that it never took off? hehe no pun intended

Actually just found this! Pretty cool, though not a monocopter
