You can call it a brushed linear DC motor :) You have a moving coil, brushes, permanent magnets, and commutators, all of which are present in normal brushed DC motors
Also got scrapped because the amount of power it took and the cost of the device was far more expensive than 1 tomahawk missile with even longer range and more accuracy.
@@keepingeel7874 I imagine we can only revisit the concept in the next century after fusion power becomes commonplace and possibly applicable to warships. There are so many concepts we've tested over the past 70 years that haven't gotten anywhere simply because it's too costly and/or we don't have the right technology yet to apply to them. Though, I think railguns will still be more expensive per shot compared to conventional missiles even when we could have the proper power bank for them.
@@thegoldenatlas753 you dont get it? Take the entire cost of that railgun prototype divide by 2 shots and you get the cost of 1 shot if they want to really build a railgun for militray use. And apparently each shot would cost as much as a cruis missile, or in other words a railgun cost more than 2 missiles.
Yeah, the Nazis already built something similar called the V-3 Cannon (an upgrade tot eh V2 Rocket). Though, instead of magnets, they used a series of charges that would apparently fire in sequence to propel the projectile forwards.
Glad to see someone else utilizing brush contact. I utilized the same in my Thompson coil build. Gets rid of the need for programming timing of coil pulses. The projectile becomes the switch. 🤘💚🤘
Seems like integrating mosfets or scrs in the launcher would dramatically increase efficiency. You could continue to use mechanical brushes, though I would think programming the timing would be advantageous
For a linear motor like this you have to engage each coil ahead of what you are pushing and turn off each one behind. I have considered using manual means like switches. Or you can use the principle that an actual rail gun uses (electromagnetic "spin") but it generally eats the metal contactors (2 rails and the projectile that contacts the two.) And super high voltages to bridge the air-gap to compensate.
Carbon brushes from power tools will work great and you could make the replaceable contacts out of copper. I think with those small mods you could greatly increase the efficiency
However, we are living in the brushless DC motor age. MOSFETs for switching, Hall sensors for detecting position, a bit more circuitry, but that's the thing...
@@DragobAttack Exponentially quick I assume… shame! And expensive to name another reason not to build it. But hey, if the calculations made show it could theoretically go up to 500km/h, it’d be a blast to see that happen!

@@AchievedZeus574it needn't be. he could use the same brushed control system as this to power coils on the rail. That might be a best-of-both-worlds option
In short, the propulsion from an electronic railway* is coming from a moving coil from point A to B. The magnets change polarization in correspondence to the position of the coil and that creates a repelling force that accelerates the coil. The faster the movement of the coil, the faster the magnets switch polarization Edit: *
The only problem i see is the scalex brushes. I work maintenance at a factory (under the training of very experienced maintenance men) and ill tell you now, if a drop of water is introduced into the electromagnet system, it poses a fire hazard. Id highly recommend either sheilding the brushes and magnets, or find some way to go brushless
@timothyluckey5020 there are companies that specialize in brushless motors and magnetic applications. If he could find some way to simplify the design and replace the brushes, theoretically it would work. Similar concept to rail guns
I have the same plane. It starts with just a gentle throw by hand. It doesnt take much at all. I even throw it with my left hand to have the right hand on the controls at all time. Very easy and simple. This is the most overbuilt unneccesary contraption I ever seen.
Regarding the length of the magnets, does it get more efficient to use longer magnets towards the end of the track? Or is there an ideal length of magnet to use no matter the speed of the sled? Or, for that matter, does the length of the magnet matter at all?
you could sand the piece of moulding in between each magnet to to stop the brush bouncing when it’s traveling - the sparks would reduce- and so longevity of components would or could be achieved through better electrical conduction - I’m sure you would get gains ( if needed )
So if you use a captive ball bearing under a spring, and with a connecting rod under the spring connected to a hook, you can use a detent relief to release the plane, rather than being forced to print a sled.
You could enhance this design by creating a long S bend power cable that is connected to a power supply and directly to the sled instead of using brushes, using hall sensors it could fire itself with variable payloads without any adjustment and by skipping the brushes it will allow you to put insulation (Thin TPU shell for low friction). Add a magnetic brake at the end to stop the sled from flying away and breaking the electronics or ripping the power cable.
it's good for Unmanned Air Vehicle, but high risk if used for launch manned vehichle. Whole body Shockness risk and other risks can bring more serious impat for human.
line a few coils up in front of eachother with contacts for each coil to make it even stronger, with 3 coils and 3 sets of contacts the power would increase by 3x
If you build that in a circle and put a shaft of a generator in the middle and use the generator power to power the magnets, you will have perpetual assisted power. With a beneficial ratio.
Surely with a small model like that , it would have been easier to use a bungee, and that would have been totally mechanical, and save carrying around great big battery's, all the bad weather risks would be eliminated, and no parts to loose.
I believe that's how alien spacecraft are powered. It explains the fast launches from earth that ppl witness. But they've figured out how to do it even in flight which makes them travel great distances quickly
I'm curious about why you didn't have something in place to stop/catch the launch sled at the end of the rails. Would this have affected the launch in any significant way?
Why don't you close the magnetic circuits with iron to increase the magnetic field strength between the magnets? Instead, you always let them "open circuit" where the field lines must find their way through the air. I wondered about this several times and thought, this can't be really efficient.
How about making it optically triggered, though? Less wear, more efficient, and if it's modular, should make it easy to optimize for different speeds/energy levels?
Could you do loop with the tracks, and see if it becomes infinitely fast until self destruct, or would there be a limit if the size and speed variables dont coincide?
If we mad these for normal commercial planes, couldn’t we eseentially make a stronger plane chassis if we don’t have to worry about weight, the launch system would get it up to speed without sacrificing fuel
There is a group in Africa. I believe Rowanda. That is delivering medical supplies with rc aircraft. They catapult to launch and land in nets. Something like this would be very beneficial to them. Look them up and maybe you help save lives. Good work.

Very cool!! But is there a theoretical top speed? Would be funny seeing a little RC Plane hitting 500km/h
The problem is, that each magnet interacts with the sled for a shorter time, so the efficency drops really quick.

Than it would be longer. And the space in between the magnets would slow the projectile down.

This is all kinds of awesome. Very nicely done
You should make the sled/sabot blaze orange so it's easier to find after launch. Nice work! Very high tech!
As a RC flier myself you get a double thumbs up. Very creative. 👍👍
That’s crazy. Cool thanks for sharing.
I love how it's mechanical❤ no programming
If your reversing polls and pulsing, then you can get better acceleration. I must warn that you need to fine tune it to get the best result.
That copper’s launch “boing” was quite satisfying
How did you pan out while installing the magnet array?
How about making it optically triggered, though? Less wear, more efficient, and if it's modular, should make it easy to optimize for different speeds/energy levels?
Could you use some type of roller instead of brushes to reduce arcing

Could you do loop with the tracks, and see if it becomes infinitely fast until self destruct, or would there be a limit if the size and speed variables dont coincide?
The folding propeller is brilliant!

Can this be used for a space shuttle???

Fun fact: if you used the propeller on the front of the plane it would also be propelled to takeoff speed using just electricity
Would be better to use Thyristor as a switching element or a magnet with a contact and many coils
Can it scale?
Can this principle be applied normal passenger aircraft that need longest runway to takeoff
How do you get the magnets to energize sequentially?
Nc it can less consume gas if it will applied on passenger aircraft
Awesome launcher!
Love it!
Is the propeller bendable in case it crashes?
If there was a way to slow the acceleration down to a reasonable speed could be used for private flights
A winch is a better solution to the specific problem of launching RC sailplanes, but the concept is interesting for its own sake just the same.
Nice work man👊
You can quadruple the speed if you use high capacity high drain capacitors.
The other side should be more efficient : coil on the rail, magnet on the wagon. No spike, no friction
