- We're back in Trailmakers making a supersonic vehicle that doesn't move. Can I engineer a supersonic catapult capable of flinging loads at over 750mph??

Sorry Spiffing Brit btw! 😅
I forgot about him. Thank you 💕
You mean sorry SpinLaunch 😉
This is probably not too dissimilar to the Spin Launch kinetic launch device...
@@jdyerjdyer lol read replies when reply
Please do some videos with him! I love you both!
Next part should be building a bridge that breaks the sound barrier.
Rce must see this
Suicidal Bridge of life
Yes
He hearted it!
Yes, the world's first supersonic bridge.
1: It has to be a functional bridge.
2: It has to get a sonic boom as a functional bridge... Not pieces of a once functional bridge.
There's something about RCE saying "aerodynamically sound" that makes me think it will work. He's got that professional authority in his voice still 😂
Yea
Hey RCE, you should start a real bridge review series where people send in bridges and you review them to find the best in the UK or the world?
Yes
i would send a picture from the biggest abomination of a bridge called pellisensalmen silta in hankasalmi finland
Ahhhhhhh the grammar
I like this idea
I agree, wvry time I see a bridge I'm split on if I should send a picture to rce to get him to review it.
I now really want just a conversation between Spiffing Brit and Real Civil Engineer on anything and everything.
This is currently being developed as a potential method of launching vehicles into space. You should try to make a space launch vehicle in the survival game… since it is the goal of the game after all.
It is also a horrifically flawed method of launching stuff into space unfortunately.
@@SilverMKI I can see the beauty in the theory, but there’s obviously zero possibility of it being used for any manned missions. As of April, NASA had decided to continue to invest in the concept to see if it could be used to deliver a payload into space more efficiently than rockets alone, but I guess we’ll see if it’s possible for the company to build a vacuum chamber the size of a football field that can accelerate a payload to 5000 mph reliably.
@RCE you could also try this on KSP; or even better, make a geostationary centrifugal space launch platform for deep space Kerbal missions … assuming it’s possible to get the vehicle to spin about its axis and the kraken doesn’t kill Jedediah first …
@@LegallyTrash stratzenblitz already did that
@retsaM innavoiG because you are putting significant amounts of energy into something that requires extremely precise timing and rapid movement of launch parts (ie the cover over the vacuum chamber, the release mechanism, etc) to function correctly. Any failure or misalignment means you are throwing the payload through the side walls of your launch chamber or ripping your launch mechanism apart.
You're rapidly repressurising the launch chamber which doesn't do hardware or electronics any good.
Much better to pick a mountain somewhere and build a maglev launch rail and tunnel up the side of it, since you can use that for much larger payloads as well as crewed modules.
You could have used the logic gate to shut down the "projectile" rockets so they don't add/change momentum after detaching.
Yeah but where's the fun in that?
Or we could make a version that's lawn dart shaped and uses the rockets to increase its range to 11
Showing he is a real engineer by taking feedback and improving his designs. It took me forever to figure out how to get the logic to work but once I did, was able to stabilize a drone for the career mode which really helped getting the tricky scraps.
I believe you can press 'c' to change between the 8 different camera modes
Also you can change the speed units in the menu
He has it set to imperial, you can check the speedometer in the UI. But the sensor isn't in imperial, there's a mismatch.
@@Xeridanus it looks like a bug on the sensor with how it's labeled, because when he set it to 800 kph, it still released at 800mph.
@@Nareimooncatt it's tilting it labels it as kph instead of km/h, the correct way to write the unit.
@@mattymerr701 kph is still correct in non-scientific use
Note, you can break the aerodynamics system with detachable blocks. You just put a single detachable block, connect all your aerodynamic fixing blocks to it, disconnect them after the creation is spawned in. Then all you have is what you want with zero friction.
Perfectly balanced game, with no exploits.
I think stacking the servos does increase the speed but you just forgot to power them
Powered? Uh oh, someone's gonna go fast now
It needs to be set to free spin
You should've made the detachable "projectile" a plane/glider!
I loved the Spiffing Brit reference. In a sense, you're both engineers. One using their knowledge to figure out how to build things, and the other how to break things. Although, now I'm wondering who paid more for their education..... You know what? It doesn't matter now that you're both highly successful CZcamsrs. It's all good.
I love these challenges, I think it woulda been neat to fling a plane or glider at un reasonable speeds
The end result is not exactly a catapult: it's more like an assisted launch for a rocket. You see, the "projectile" part still has active rocket engines. It would be more "fair" to detach just a cabin.
Trebuchet
@@akashics1275 a trebuchet is just a bigger better but slower catapult
Yeah, I would've had the rockets along the arm and then detach the cockpit from the end of the arm, instead of detaching it all in a big unit.
I'm 90% sure when they were talking about stacking servos, they were referring to "powered" servos, 1 servo spinning at 10kph + 1 server spinning at 10kph = 20kph etc.
You should play “Airship: Conquer the Skies”
It’s a pretty cool game.
This was a joy to watch. Getting to my EE roots with the logic gates and sensors. :3
omg lmaoooo i love when he impersonated Spiff. that made me bend over laughing
You should use the angle sensor instead of the altitude. The way it's set, if you're headed down from the top when you hit the speed setpoint, it'll detach anyway. The angle sensor would let you be sure you detach at the optimum point.
Maybe add just a bit of weight to give you a stabilization fin for the flight?
Also, check the cockpit weight. You might be able to balance the load with the engines in the axial direction - engines on one side, cockpit in the other, with just the cockpit and it's streamlining detaching. Use a flat connector to hold it to the side, with the detachable block behind the cockpit attached to it.
I'm a mech eng myself.
Potentially too he's going to get better range out of about 35 degrees over 45. But it depends on the physics modelling in Trailmaker taking into account drag properly.
As far as I know, there’s just a spinning joint, which would be a lot more free than a servo
Reminds me of the SpinLaunch rocket that uses centripetal force to fling a payload into space. However in their setup both ends detach so the remaining arms are balanced
You took a 10-minute topic and stretched it out to over 20! Now THAT is skill! :D
On a serious note, servo stacking _is_ a thing in TM, but it only works if you power them. If they are free-spinning it does nothing. Also TM tends to get unhappy if there are large side loads (like a long support pillar) on hinges and such since those are not all that rigid at high loads. You can even see servos sagging when they were stacked to support the catapult at one time. Point is, making this catapult's base into a U shape instead of two separate pillars would have been way more stable.
And lastly, why not use angle sensors instead of altitude? Would have been way easier to program the release angle.
Awesome! Very satisfying to get that successful final launch.
Cures my extreme spicy sadness
We engineers like complex solutions too much and this video perfectly demonstrates that. The first design was okay but it quickly got complex and as a result it took a long time to make it work... it is so recognizable (unfortunately most architects know of this weakness too and they often use it to make fun of engineers 😜)
Damn RCE even killing it in the Electronics engineering territory.
I have to say thanks to you playing Trailmakers when you had about 40k subs I found my favorite game. I had not touched a sandbox/creative game ever but this game is the best! It's not exactly perfect with its quirky mechanics but it is the perfect mix of Legos and Hotwheels!
Thanks a ton!
You should watch the video, where Stratzenblitz75 did that in KSP, but a bit faster than supersonic (or not depending on your definition).
And yes, the physics engine was abused.
Thanks to this video I now understand trailmakers logic blocks. Thanks XD
Would love to see you launch an actual flyable plane in this manner!
That Spiff imitation was on point! 😅😅
I hope you two will make some kind of collab 😎
I feel like games like this show really well the thought and making processes of engineers and similar professions
0:20 Looks more like a G-force centrifuge than a supersonic machine haha
6:51 People of culture know what that number is 😂
These vids are always the best
This is my favorite supersonic build so far
Something I didn't know I needed. Thanks R. C. E.
Spiffing Brit impression was spot on!
You do know the cockpit has perfect aerodynamics right? Even the blocky bit
“World’s sketchiest piece of scaffolding” haha 😂
I would love to see you launch something but it to be controllable, like a glider.
Chrome bumpers in accessories also have no airodynamics, so you can use them functionally to make corners or bars.
Btw, if you use detachable blocks to cover all aero surfaces and then detach them then the aerodynamics are miscalculated and you get zero drag. All of the top dragster race vehicles use them
That was a really cool build
Hey RCE, just a tip, you can press backspace to clear the map without needing to quit.
20:10 The KRAKEN is calling you 😂😂
I love your channel so much. I will join the engineer team one day.
Thank you! like always.. SUPER INSPIRATIONAL!! "sometimes YOUR genius is almost frightening!" JC for RCE
You should add control surfaces so you can fly the detached bit after it launches you!
This whole thing reminds me of that company, (Spin Launch, I think), that's trying to do this exact thing to reduce the fuel needed to get satellites into orbit.
Nice use of logic!
Bet Scrapman would be impressed :P
Super Sonic Catapult FTW! That was awesome!
I had never heard of this game before, watching this made me buy it straight away.
Now im going to have a little fun now!!!!!
Just loving your content my friend.... TY
the spiff reference was so good lmao
Damn bro, you are killing it with the youtube stuff new video every day, keep up the grind
this is some back to the future material here XD
Day 1 of asking RCE to play from the depths
Day 1 of supporting this person asking RCE to play from the depths
Day one of supporting both @Mepitycat2 and @B OI
Day 1 of also supporting this person asking RCE to play From The Depths
Day 1 of forgeting to ask RCE to play from the depths
Day one of supporting all these people who are supporting to see rce play from the depths
Spinlaunch taking notes lmao
Literally love this game. Play it more
dang it Matt, you need to change the button for the rotating servo to space like the thrusters
this was a fun watch
This device works more similarly to a trubuchet than a catapult, but it isn't either. Fascinating.
You should make a super sonic glider thrower
That's basically the concept behind that "Spin Launch" system
Replace the altimeter with the angle sensor so you can get the right angle, the altitude doesn't matter if the angle is right though you could get both if you make AND go to 2nd AND along with the 3rd sensor
This type of game is your shining moment! Could watch you engineer toys all day! Wish there was more content like this and not weird card tower defense games lol
good video man!
An idea I had, you could use the concrete walls dispensers to make a bridge.
This is literally the Spin Launch lol
Trailmakers is Perfectly balanced with no exploits whatsoever.... Oh man, I love you both!
You've reinvented spin launch
I like how you made your own biggest fan
there is a no drag glich in the game.i love you.
Make the flying part land safely!
It's a similar concept to the real life SpinLaunch project! 😀
Something about this idea terrifies me in a good way. Cuz now I'm imagining a super sonic boulder slamming into a castle wall like a darn meteor or something.
RCE, This is material for the (Kerbal) UK Space agency. In the US there is this company (spinlaunch) that is doing it for real!! super cool to check it out.
The all new real sound engineer
Haven’t watched since around 100k subs and it’s crazy that I came back and you have over a mil 😳
Well the engines on the flying bit may have helped it to get further but it did look very cool
Building on this theme, some sort of catapult missile where the detachable part has wings!
Dear sir,
technically a trebuchet, no torsion/tension mechanic, this is just acting as a rocket-powered traction trebuchet. Invented by the Chinese. Great engineers, they were. The Mohists in particular would have been HUGE fans of this game.
Sincerely,
A pedantic military historian.
This video, ironically, made me think of half-life 2. One of the most amazing parts of that engine when released was realistic material deformation and destruction.
I really want a game with next gen versions of this. Imagine this game with realistic wood snapping, or steel warping at speed/temp. Would be really cool.
I wonder if he could build a helicopter that used supersonic blades to gain elevation?
I love watching match struggle to figure out logic in trailmakers Because it's probably more simple than real life logic
the catapult needs to have detachable planes on the end!!!! super sonic planes!!!
hmm didnt expect to see logic gates in a civil engineer channel XD
damn, You are so clever matt!!! Love to see it works.
I can't believe that, I can't believe that lmao 😂
Throw some wings on it and you have a spin launch system!
Why do you use an altitude measure if there is an angle measure? That will give you more precise control over the launch without having to remeasure it all the time.
it’s like the game says that there’s a max frequency for the laps so, following the conversation of the angular momentum, to go faster you only could make the radius longer, sorry for bad english
You should make the part that gets flung controllable!
"Local man engineers supersonic amusement park ride, neighborhood children flock to try it."
This made me think of the spinlaunch company that is trying to launch stuff into space by spinning it
Could’ve also did it with a distance sensor on one of them. As of the speed idk if it would be better at the top or bottom
this was great!
Real civil engineer is a god he will live to be a famous person that loves strong shapes…
That was awesome.
