Mhm a Stirling engine could work fine the main problem with a Propan troch is it needs to move a lot of air to generate thrust but with a fan (electrical driven) prior to a burning chamber it is possible to generate thrust by expanding the air with heat so it gets fast out of the back called hybrid jets

[@fairguinevere666]

The fun thing with the BV141 is the tail design wasn't because of the asymmetry - it was for the tail gunner! They wanted them to be able to not have to worry about the stabilizer being in the way. It was mocked for its design so never saw production beyond the first prototypes, but filled the role of a single engine scout/bomber that it was designed for pretty damn well in initial testing.

[@Tallslimchris]

You probably already noticed this but each time you push the copter wings with the launch pole, you’re inverting the angle of the blades turning all that wanted upward thrust into downward thrust, or no thrust just gravity, but it is a great idea and I think Peter can get it to work, little bit lighter blades with a better angle and “out of box” design,

[@moonriseproductions]

so the best launch would be to hold it high, then just pull the pole down, and run fast

[@LaurenceVonThomas]

@@moonriseproductions or jump off of something

[@bmxscape]

@@moonriseproductions well realistically if it can't take off from the pole on its own it would never sustain flight

[@Tallslimchris]

@@moonriseproductions actually the best launch would be for the copter to slowly gain proper lift and lift itself off the launch platform, the use of the pole should solely be used to stabilize the unit until it can sustain its own lift. Unless it’s purpose or design is to slowly fall like a parachute or a glider, then some form of launch or drop from a secondary unit be required.

[@darrenfalconer3267]

I don't think they would be inverted, looks more like they are just flexing down. Pushing it up doesn't invert the pitch of the blades. And that's even less likely to happen since he added the small wing. This just looked like it didn't produce enough lift.

[@Demdere]

Hey Peter - project idea! What if you made a plane without ailerons, and instead had the main wing on a rail that moved the wing left/right to tilt the plane one way or the other, due to the imbalance of lift on either side? To explain it another way: The wing (when moving on the rail in one direction) would be getting longer on one side while getting shorter on the other due to the linear motion on the rail, 90° from the direction of flight.

[@rcbinchicken]

that's a really creative idea, I'd watch the hell outta that

[@urmum8540]

Sounds like rotational torque would be a big issue

[@TheFlyingZulu]

I think that's how some hang-glides turn... The person shifts their weight and thus moves the center of gravity left or right making the craft roll and turn in that direction.

[@netts2315]

And have the propeller on a rail too to make an offset in the center of thrust relative to the center of gravity, giving you yaw control :D

[@Scrogan]

Move it forward and back for pitch too? Wing-warping could be interesting also, though the rib design for warping wings may not be trivial.

"This is a really big shaft, and this is a really small hole" is priceless

[@La.máquina.de.los.sueños]

For a single blade helicopter, you need propulsion at each tips of the blade, pointing in opposite direction (to get a clockwise or anti-clockwise movement) ... like they do in China with fireworks flying wheels. The centripetal force helping, it'll stabilize the wing.... but all the weight being at the tips, it'll also increase the possibility that it tears apart.

[@leftaroundabout]

Actually it should be ok with propulsion on only one tip. However you do need a counterweight, so that the center of mass is reasonably far away from the prop so that it can create good torque. The designs in this video didn't have that. Best is of course to use the battery as the counterweight.

[@williamcrane8236]

@@leftaroundabout Charybdis, McCutcheon's machine, Flying Maple seed. Plenty of examples on youtube of them. Might not be strong enough structurally but looked like his center of rotation was too far off from his center of balance. For the two bladed one I would go with a smaller prop delivering higher speed but less static thrust. I think he got all of the thrust out of the big prop he could but it just wasn't high speed enough especially so close to the center of rotation where plenty of thrust is going in the wrong direction just because Angular moments are wrong. I ran a Monocopter challenge on RCOnline back in 2007, it was fun and I flew them all the time with little cox engines or a Norvel 15 powered one with a wing made of 2 mill coroplast SPAD style. My biggest was the wing from my first Ugly Stick when the fuse wore out. Ran a throttled os 40fp for power. On a still day I could throttle up, take it high, throttle down and let it come back and change altitude. It was a flying oddity. When I started flying Norvels for 1/2A I no longer needed the 25% fuel for the Cox engines, And I put the things up for memories sake.

A thought for launching the helicopter. Spin it clockwise, as viewed from underneath. Mount it to a threaded rod via a large nut (1/2" 18tpi). screw it onto the rod about 4 or 5 turns and let it spin itself off the rod. No more trying to push it up to launch it.

Happy 2023 everyone. A wonderful channel I've found.

[@tomshepherd4901]

Ideally, the propeller should be at the end of a rotor. This produces greater leverage at the interior of the blade and produces more thrust. That's why rocket helicopters have the rockets, (20 lb thrust) at the ends of the rotor to produce much greater thrust for flight.

[@nunyabusiness4651]

Toby "Cut hotdogs, Now wait a minute Peter!" 😅😅

[@nealmiller8356]

Put 2 angle grinders on a plane frame, with propeller sets for each tool. Or Battery a operated router, putting in a reducer gear that slows down the amount of startup torque initially generated. Hopefully that would take enough stress off of the airframe before the launch.
