dominicm Posted April 17, 2018 Posted April 17, 2018 I was quite amazed by this. I had never seen or even heard of a Magnus Effect plane until Finley showed up with what looked like an upside down lawn mower. He's a very articulate kid and talked me through the physics of how this thing works. It doesn't just work...it flies really well...and he built it totally from scratch. Quite looking forward to seeing what he comes up with next.
Charlie Harper Posted April 21, 2018 Posted April 21, 2018 HA! Very interesting! Just wait till the gyrocopter guys get a hold of this...
PommyRick Posted April 22, 2018 Posted April 22, 2018 Amazing effort by this young man. It's quite incredible how magnus effect works. It's also being used in the maritime industry to generate additional power/reduce fuel consumption. Wind-powered ‘rotor ship’ a first | Port Authority New South Wales
allowera Posted April 23, 2018 Posted April 23, 2018 Back in the 1970's there was a polystyrene 'kite' called a Rotorplane that worked on a similar principle.
pylon500 Posted April 23, 2018 Posted April 23, 2018 HA! Very interesting! Just wait till the gyrocopter guys get a hold of this... Looks like the Russian gyro guys have already had a go...
kasper Posted April 23, 2018 Posted April 23, 2018 Looks like the Russian gyro guys have already had a go... Needs higher mast to give more pendulum stability.
MikeBravoYanky Posted April 24, 2018 Posted April 24, 2018 Needs higher mast to give more pendulum stability. NO.. "pendulum stability" will not help.. You would just end up with big lateral dynamic oscillations.. lateral divergence is a "dynamic stability" problem which can only be solved with damping or the equivalent of dihedral producing opposite roll with side-slip (like a big central fin above the rotor) or effective roll controls.. The gap in the middle is also a big lift killer..
kasper Posted April 24, 2018 Posted April 24, 2018 Strangely the video of the model at the top of this thread clearly uses pendulum stability for roll stability and a rear rudder for direction. So I’d disagree
Birdseye Posted April 24, 2018 Posted April 24, 2018 The construction of the lad's aircraft wing and the Russian attempt are also quite different.
MikeBravoYanky Posted April 26, 2018 Posted April 26, 2018 Strangely the video of the model at the top of this thread clearly uses pendulum stability for roll stability and a rear rudder for direction. So I’d disagree I was only referring to the Russian towed thing.. model is different for a number of reasons..
