Very informative experiment and coverage! Thank you for sharing our mission Peter! If anyone's interested in getting the full picture of issues like the one in this video, check out the link in the description and let us know if you have any questions.
That would be an insane platform for long range OWA UAV deployment. Have the 'engine' car towing the OWA craft with the (relatively) expensive long range comms and power packs. Give the carriages just enough DV for terminal adjustments and just enough comms to communicate with the engine car then have them glide to target. You could detach carraiges as you go to service targets of opportunity or all in one go at the primary target to overwhelm defensive systems. Have the engine RTB to pick up another batch of carriages with your expensive batteries and flight controller intact.
I think the main problem is caused by connecting the carriages together from the front and back, this sets up the pitch feedback loop instability, where the leading carriage pitches up pushing the following carriage nose down etc along the line. If instead you connected them from CG to CG down each side, like a team of horses pulling a carriage, they would follow each other without inducing the pitch oscillation.
I'm also insanely curious what would happen should he add a follower engine like you see on typical train setups. Obviously in this case both would be forward, but he said in the video that they weren't flying good. I think adding a second set of engines somewhere could be good.
I was thinking the same thing about feedback but rather a different hinge point, oppose the flying surfaces so that car responds opposite of the car ahead of it.
I love the idea of a plane pulling a second carriage, touching the runway at some place, discarding the carriage and then just continuing on to another destination
A bit more complicated way of dragging gliders behind planes like it was done in WW2 to get soldiers behind ennemy lines using disposable unpowered gliders
As a mechanical engineer, I have only one recommendation; add springs and dampers! I think the swaying can easily be mitigated with some damping, while not losing the train-like flexibility.
I was thinking a caboose with some extra drag could help pull the links into more stable tension. Maybe with a spoiler on an rc axis so its taughtness can be varied.
As a non-engineer, I wonder what the benefits of having so many degrees of freedom really are. I understand why the cars need to be able to have a different pitch angle than the tractor, but why not use two couplings to limit freedom to pitch only?
Dragon train plane ... Video Idea. 2.0 consider Delta Wings and and Control surfaces on every segment each controlled by gyros. For landing on the tracks use a runway with a funnel at the end. To Put less Stress in the engine maybe Put smaller engines in every segment. Modern electric trains have many electric Motors 🤓
I love what Sripol Industries have come up with this time! Flying train, heck yeah! It moves a bit like those dragons over at cultural Chinese displays.
From towing trailers I know that drag is actually your friend. The more aft drag the cars supply, the more stable your tow vehicle is. Consider adding a little aft weight, countered with a larger wing, for the "caboose." Or even try a small motor on the very last car that has reverse thrust. All you want is enough to keep the trailer behind you. From the video, it appears that each individual car has is own CG, so making these changes should not hurt too bad. You may also find that overall the plane needs to be heavier with bigger engines. Add length to your cars to reduce your oscillation. Make them twice as long. It won't solve all the oscillation issues, but it may settle some.
@@JeffreyOller It wouldn't work too well considering the fact that he can release the cars from the main engine. Unless you put the main power in the last car and then a small battery in the front just so you can land it.
I know others have mentioned a chinese dragon kite... but this looks like it would be an AMAZING basis for a long flying dragon. Might need more power/ motors to get enough thrust, but a 12 foot long tail flying through the air would be dope with a nice dragon head on the front
You just gave me an idea. If we could build an infrastructure of skyhook tow lines we could have a shuttle system like this where you hook a glider via tow line to the skyhook, get towed to a point near your destination, disconnect and glide to the airport. You could even have multiple glider shuttles that disconnect at different stops.

@@clintonleonard5187 I already left a separate comment about this, but that idea is very close to the invention in the book "Tom Swift and his Sky Train" :)
Maybe you could do something like a very slightly increasing drag with each car in the line, so the one in front always wants to go faster than the car behind it, holding tension between them at all times (more or less)? Just a thought. Great job as always!
Maybe you could try adding a gyro stabiliser to the last car somehow, completely independent of the electronics in the first car, to counteract the yawing motions and the oscillations
Birds use their tail feathers for drag. Add a parachute at the end. You probably don't need any wings on the passenger cars, since the u-joints will keep them oriented similar to the engine.
If the cars break away, have a set of mini wings pop out, that pitch the nose up slightly, for a glider to the ground. The pin release could retract into the first car, spring activated, that controls the wings…
The cars essentially already are gliders. The problem is them being attached to each other. If they could all disconnect, chances are they would glide down more safely.
maybe dampers on the couplings for sideways movement... or mass/fluid damper inside the last car?.... or maybe a way to stiffen the whole train once airborne :) I love trains
I'm thinking about thin carbon rods, or if you've ever used goldenrod for control surfaces. You could insert or retract those semi rigid rods to control stiffness.
It's a flying dragon! 🐉 A great mythical beast! "It's a dragon!, It's a dragon!" 😂 Seriously, looks like one of those Chinese dragons flying in the sky.
The tail wagging issue is turbulence off the previous wings. Model it in software or in a wind tunnel. Now you need to be able to land it back onto the tracks and operate it like a train. I envision the landing "strip" as a funnel shape. It would need to be long and wide, tapering gently to the width of the rail. This would reduce the accuracy needed to land and, hopefully, gently and accurately guide the vehicle to the correct alignment on the rails. Practical? Nope but fun! The rail gauge needs to be wider to provide better roll stability. The side surface area and the flight surfaces are providing lift when there's a crosswind as well. A wider gauge will help there. Deeper rail connection with the wheels might help too (the wheels will ride lower in the rail providing more resistance to rising over the rail when there's a crosswind).
Possibly. It may also be an instability just of the configuration of the aircraft (ie it would persist even if none of the downwash from the wings affected the wings behind it). A small change in orientation of one section causes a larger change in orientation somewhere else and so on. Only way to really know is to model its control dynamics or throw it into a wind tunnel.
Passively actuated control surfaces on the cars: gimbal joint left/right actuates side rudder, up/down actuates height rudder. No servos or gyros needed, just mechanical links from the joint to the rudders. Add dampeners if you're feeling fancy.
I'm thinking add an accelerometer and a simple microcontroller/flightcontroller to each wagon and try to auto-level each wagon individually. Turning might become harder without coordination, but that should result in an overall more stable train(If you can get the PIDs to work correctly - Probably need to tune them for every wagon. Maybe just add a few wagons with active control, maybe even an independent set of motors).
Finally! I've been suggesting this for ages! Also, the last car should have a vertical tailfin. The wing stabilizers on the cars should get closer and closer together the further back you go from the engine. That should mitigate the serpentine swaying while in flight.
I was thinking this too. And to add the effect of drag on the main engine, each following car would be powered down slightly from the one in front of it. Essentially taking the majority of the unpowered load off the main engine but still allowing for some resistance to pull in a straight line.
one idea that comes to mind: every car has servos for flaps. no engine, etc, but controllable flaps and a flight controller. in theory, even engines could be interesting.
This reminds me of glider towing, But in full scale, you'll have a pilot in both aircraft. This could work, but you would need a computer to constantly stabilize the cars in flight.
Absolutely. The flying wing design had some serious stabilization issues until the computer era ... well uhm .. stabilized it. B2 spirit versus the Northrop flying wing.
honestly despite how utterly ridiculous and impractical this is, its great to watch you try an idea, iterate and eventually achieve something that sort of works, the whole process is so cool :)
This, but make all of the flight controls work by pivoting on the train car connections. The position of the cars will dictate the flight and eliminate the twerking.
Probably the most entertaining form of gadgetbahn I've ever seen. Also, you're right about the zero-series Shinkansen looking like an aircraft, its design was inspired by airliners specifically for aerodynamic purposes.
You can keep the vertical stabs and put in centering springs between segments. If you design it with some jointed beam that is rigged with cables you might even be able to use all the cars for steering. Maybe ball joints, with a cable/pulley system that runs on all four sides of the beam. Though I think the issue is finding a good way to rig it in this condition
Imagining the chaos if you were a passenger in that car had me rolling with laughter. Having your window be parallel with the ground 1 second before landing is so crazy.
What would be really cool would be making each car independent when they're dropped - and then giving them all gliding ability, so that when you pressed the button or flicked the swich, it would just kinda evaporate into loads of little cars (it'd have varying coolness based on how many cars in the train)
Super cool! I wonder if you add something like rubber bands on all 4 sides between the cars to act almost like a shock absorber. I wonder if that would help any.
The only reason why it didn't work is because during flight you didn't lock links in between car. The reason why the links are flexible is for rails. In the air, you need to lock the links rigid.
Loved the project, and the background music. Seems something it will appear in a studio ghibli movie. Maybe if each one or some cars there was another with motors and contolled surfaces, but that will need some computer control to make it auto correct in order to avoid the rocking motion (or two people...or mirrored controls).
12:36 That kind of movement remind me of the Ghost Leviathan from Subnautica Dress that up as one (somehow,without taking away from the functionality) and you'll make people scream
A train airplane is a perfect situation to try an oblique wing configuration! The wings can be pivoted inward/parallel along the body of the train while on the ground then fully perpendicular when ready to lift off! Multiple oblique wings along the length of the train in a zig zag configuration during level flight for maximum stability. Perhaps locking mechanisms in between the cars to lock them in place and keep them straight after take-off. Possibly, a pusher motor in the rear car after locking.
The final engine-plane design looks so cool to me, especially when you flew it around a few times on its own. Really kind of imposing and powerful looking.
Pitch the wings in back up and make the slightly more v shaped dihedral style and a canard on the first "trolly" to have a second person control it on its way back down! That would be sweet!!!
I'd like to see what active stabilizers would do on the follow cars, see if you could use some sensors and really smooth out the transmitted oscillations from the earlier cars. I think you could get the train length much longer then, plus it would be wild to see it really stable in the air.
Try making the couplers more robust! I think they were rigid enough for the scale of the experiments you ran, but not enough for the full sized model you built. Super cool build though! It totally looks like a big sky centipede!
Maybe another HUGE vertical stabilizer on the trailing car along the centerline could stop the wobbling? Increasing the size of the wings for each car as you move to the back of the train could help lift the tail and keep the whole setup from being tail heavy. Each car having smaller wings then the engine seems to have negatively impacted lift. Idk just a few ideas.
You need tighter U-joints to link the cars. Torsionnal stiffness is lacking and it adds to the rear car instability. Wing position could probably use a bit of tuning also. Maybe a bit more angle of attack?
To improve stability, try stretching the train out further. Reduce the drag on the central cars by straightening out their vertical surfaces. Rear car: Angle the vertical surfaces on the rear car to create more drag and keep the train stretched tight. This setup should help with self-correction during flight and minimize slack between cars.

Greetings from an other continent !

probably doesn’t need it for every car either. Could probably have it on just every second car and the last one
I feel like you'd need to run this in a simulation, and train a neural net to control active surfaces on each wagon.
That would very likely endup way more unstable, connecting multiple self-regulated parts is very tricky.
Next, try to get like 50 feet of track flying in a line, and have a normal (lightweight) train drive on that track.
A stabilizer hitch helps with trailer sway. some sort of resistance at the coupler to reduce movement might help. Cool experiment!
Finally! I've been suggesting this for ages!
Also, the last car should have a vertical tailfin.

Super cool! I wonder if you add something like rubber bands on all 4 sides between the cars to act almost like a shock absorber. I wonder if that would help any.
The only reason why it didn't work is because during flight you didn't lock links in between car. The reason why the links are flexible is for rails. In the air, you need to lock the links rigid.
Then it’s just a normal plane
Pls do a flying bed Pls like this comment 😄
Loved the project, and the background music. Seems something it will appear in a studio ghibli movie. Maybe if each one or some cars there was another with motors and contolled surfaces, but that will need some computer control to make it auto correct in order to avoid the rocking motion (or two people...or mirrored controls).
12:36 That kind of movement remind me of the Ghost Leviathan from Subnautica
Dress that up as one (somehow,without taking away from the functionality) and you'll make people scream
You could make a sick looking dragon with this concept. Love it Peter🔥🔥
A train airplane is a perfect situation to try an oblique wing configuration! The wings can be pivoted inward/parallel along the body of the train while on the ground then fully perpendicular when ready to lift off! Multiple oblique wings along the length of the train in a zig zag configuration during level flight for maximum stability. Perhaps locking mechanisms in between the cars to lock them in place and keep them straight after take-off. Possibly, a pusher motor in the rear car after locking.

The final engine-plane design looks so cool to me, especially when you flew it around a few times on its own. Really kind of imposing and powerful looking.
Need to make this again with detaching and separately controlled planes! Awesome channel.
Pitch the wings in back up and make the slightly more v shaped dihedral style and a canard on the first "trolly" to have a second person control it on its way back down! That would be sweet!!!
11:58 i started cracking up when the wheels fell off LOLLL
Try adding a gyro and servos to the back car to try to stabilize it. Great build, keep building outside the box!
I love how you almost hit the ground camera when dropping the cars at the end; unbelievable aim 🙂
Excellent.congrats for this project
2:29 cool transition
Really would have liked to see a barrel roll with all the cars attached, but still a wonderful video, as usual. Thank you Peter
I remember when Flite Test was this cool 😄 Keep up the awesome content, Peter!
10:10 the songs that starts here is called "Piccolo and a Cane" for those who are wondering. It's also probably the electro swing version
Goin off the rails like a crazy train!
I'd like to see what active stabilizers would do on the follow cars, see if you could use some sensors and really smooth out the transmitted oscillations from the earlier cars. I think you could get the train length much longer then, plus it would be wild to see it really stable in the air.
Try making the couplers more robust! I think they were rigid enough for the scale of the experiments you ran, but not enough for the full sized model you built.
Super cool build though! It totally looks like a big sky centipede!
Maybe another HUGE vertical stabilizer on the trailing car along the centerline could stop the wobbling?
Increasing the size of the wings for each car as you move to the back of the train could help lift the tail and keep the whole setup from being tail heavy. Each car having smaller wings then the engine seems to have negatively impacted lift.
Idk just a few ideas.
You need tighter U-joints to link the cars. Torsionnal stiffness is lacking and it adds to the rear car instability.
Wing position could probably use a bit of tuning also. Maybe a bit more angle of attack?
It looks like a really fun plane roller coaster
as a train geek and a avation geek my favorite idea ive seen on yt for trains and planes
To improve stability, try stretching the train out further.
Reduce the drag on the central cars by straightening out their vertical surfaces.
Rear car:
Angle the vertical surfaces on the rear car to create more drag and keep the train stretched tight.
This setup should help with self-correction during flight and minimize slack between cars.
