That wall shot(s) was incredible
Sam, it looks like the CO2 bottle is not producing purely linear thrust but due to imperfections in how it is pierced or an off centre hole, it is also producing yaw causing the secondary wing drop. The yaw plus the high AoA due to the high pitch power couple is causing it to spin. Perhaps some kind of nozzle screwed on to the CO2 bottle may help this.
maybe a little more dihedral angle for the main wing ? friggin awesome thought
I absolutely lost it when it smashed into the wall, and when it happened again, I laughed so hard I got lightheaded. The noise it makes and your gutted reactions are so perfect.
The plane just abliterating itself on that wall repeatedly will never not be funny lol
Genius mechanism allowing the motor to detatch. I've worked in private military tech/production for years. Ive been stewing around the idea of a field deployed rocket powered glider/yard dart. Install a small camera, servo to live target from the field. Load the cone or body with something that detonates on impact. I like your system and it gives me some ideas for application on what is in my head. The reality is drones have proven their place in the modern field. America is great at producing weapons that cost a fortune to often target one man. You can mix a stable rocket motor capable of easily launching a small glider or lawn dart design a mile plus. The components would be next to nothing as well as live video feed. You're pinned down by sniper fire, deploy a small desposable glider with live feed and impact explosive. The entire unit could be built for a 100 bucks easily and be made dummy proof. If you used an aluminum body and cone in a dart form the kenetic energy and velocity from just 10,000 ft with a small altimeter to detonate a squib in the cone causing the kinetic energy release would be incredibly devastating. I like what your doing keep up the good work.
Could you design the puncturing spike to become embedded in and seal against the canister? Maybe with rear-facing "ridges" that could prevent it from being removed, similar to a bee stinger or a plastic rivet. Then you could have a hollow portion down the center that you could design into some kind of nozzle to direct the thrust and maybe use it more efficiently?
Because the initial CO2 cartridge is so far down, on the sled, under the plane, it creates a thrust lever effect on the planes centre of mass , making the plane pull up.
Love the Idea of using a co2 canister and the launch mechanism.
The CO2 cartridges on those C130s are huge!
That second wall smash had me snort laughing lol!!!
This is awesome! I’ve experimented some with slingshot airplane designs. The hardest thing is finding a design that glides and behaves well at higher speeds. I’ve found a wing with a swept leading edge and straight trailing edge is the best middle ground. Those are also stronger than a straight wing. Edit: I thought of something else: your point of thrust needs to be right under the center of gravity. That’s why pop bottle rockets have a long stick, to balance it out and make them fly straight.
you've made me appreciate the R&D process. frustrating, and the feeling of giving up, but pushing forward.
Pissing myself when both planes smashed into the house 🤣🤣
Great vid. Looking forward to seeing you progress this project.
By using a specific shape puncture pin, opening that it forms can be shaped into a pretty accurate nozzle. It would be similar to how metal forms during friction drilling, only here it will be from impact of the pin. Hopefully this will make thrust portion of this glider more controllable. The force from the canister can pull a linkage that moves the elevators on tail to give it directional (or rather angle of ascend) control. As the tank drops off, a rubber band would pull the linkage back, returning the elevators to neutral for a nice glide down. As a side note, welcome back after nearly a year! lol
From that last slo mo, it looks as though there's still a fair bit of co2 in the canister after it leaves the metal extrusion, so it's still propelling but free to rotate upwards when it leaves it.
Welcome back pal nicely done Keep em Coming
we need more of your channel!!!!!!!!!!!!!!!!!!!!
A colab with Tom and his air piston and this to do an initial launch would be cool
Awesome video. Great work
Neat! I'm looking forward to the next version!
Once upon a time, I turned those CO2 cartridges into mortars. I used a pipe just sightly bigger and put a small brad nail through a board I rested the pipe on. Drop the cartridge and when it strikes the brad at the bottom, it turns into a small rocket. It would add complexity, but maybe you should consider variable swept wings. You might even be able to have the sweep angle tied to the carriage you jettison. This would allow you to reduce drag and lift under thrust, but once gliding the wings would extend. It should reduce the effect of the plane rolling when it is under thrust.
Hitting the wall twice in a row had me in stitches 😂😂😂
To prevent the plane from rolling, add wingtips. These will prevent unwanted airflow from high air pressure from below the wing to the low pressure above the wing
Well done!
Just say CG oh my goodnesssssss. Otherwise, awesome video!!! so fun!
Interesting new mortar technology
Canard wings may be able to help counteract the initial nose up at launch (along with an optimal CG). Keep doing what you do 👍‼️
You're now my favorite "don't do this at home" channels!
2:00 You have a shockingly good cameraman. XD
To the Moon! Wait, wait, The Wall again. 😂 Great video.
Awesome video as always Sam. Glad to see you still making daft shit and having a laugh
Should have used a twin tail delta wing lifting body type fuselage [like the F-15 for instance]. This also allows for 2 engines.
Another thing you could try is adding servos to the plane for controll
this reminds me of the catapults the us navy uses to launch their aircraft off the carriers
Highering the center of lift or lowering the center of mass could make the plane more stable and reduce how much it tilts left or right
excellent.
Good video and F for the planes that kamikazed into the wall 😆. Here are some suggestions : Maybe by having the sled stop at the end of the runway it would waste less energy rather than using that energy in making the sled fly Also just optimising the release design as on a lot of shots an orange piege flew off while the plane was in the air A nozzle would help with the direction of gas and maybe adjustable wing elements especially at the rear could remove the high pitch up at the cost of increased weight I think an auto adjusting tail and wingtips could be feasible like with toy helicopters with a small wing/falt surface tilting blades but would require a lot of development Good luck if you make a part 2 or for other videos👍
so cool
Perhaps a nozzle attatched to the co2 capsule will help stablize the gasses allowing for a more controlled launched.
Awesome.
i wish you uploaded more often
Try a containment or regulator out the back so it reduces the thrust by 50 percent
More dihedral might help make the flight path more predictable. Not sure how well that would print though.
More! More of this.
awsome dude..but i think you guys should make the tail longer..that will make it more stable fly..😊
You're on track to making a Co2 powered hunter killer drone from Black Ops 2.
I would attempt it with a long fuselage, if it’s anything like a boat, longer equals more stable with instant power
Needs a De laval nozzle to increase efficiency. You can see the gass exiting the throat of the cartridge is significantly overexpanded.
Dude!, not 1 but 2 crashes into your house! Find a field! BUT, it was entertaining!!
There was a aerosol spray toy airplane that would fly 2 blocks It had a heavy long rubber engine. And a nozzle. Filled up ba a aerosol can In the 60s
With those rotors, you will also have to think that they don’t just turn the plane side to side they roll the plane toO
I wonder how the performance would increase, if a diverging nozzle is attached to that CO2 container.
Sounds like stability issues. I would suggest printing a bigger plane so that it can use the full power of the co2 cartridge
If you were to try and remake it use the f104 design it's kinda the most aerodynamic design right there there with the sr71
A 3/4 inch PVC pipe tube is very effective of guiding a CO2 cartridge in a line
nice
The problem is the hole punctured in the CO2 bottle is never regular. You need to incorporate the puncturing device into the plane then have the CO2 emitted via a predictable nozzle. You need a gasproofish nozzle system.
Babe wake up sam barker uploaded
I’m sorry I woke you
Wouldn't it make more sense to stop the sled on the alu track, rather thannhave it fly away with the plane, only to disengage in midair? The way it's set up now, the residual pressure in the cartridge extrapolates any movement the plane makes after take-off.
This is cool but wait until you need a remote id module on it
You didn't mention making a smaller gauge hole to reduce the power output.
I am a college student who is designing drone injection. Can I get a 3d modeling file of the device that fires co2 cartridges?
I was thinking - your accent is very like Tom Stanton's. And then he turned up. Where are you from, like, rural Essex?
Spot on
2:03 Better the brick wall instead of the window, I supposed. Littler easier to FDM print a new plane than it is a new window.
Where do you buy these
So it’s like a v1flying bomb it’s cool and interesting
nyoooooooooom
Congratulations, a mini V2. 😆
Glider body.
This is why some KIDS need adult supervision!!!
pleas consider using radio control . at least some gyro control
To the moon!
Hi there - is there a link to the download ?
Next up CO2 boomerang!
🥶
@Sam Barker Monowheel update?
In the process…. Shhhh 😉
You're probably losing a fair amount of thrust by under-expanding your flow, the pressure of the flow coming out of your "engine" is definitely higher than atmospheric, and really you want it to be as close as possible to atmospheric pressure at the end of your nozzle that way all of that pressure potential is being converted into kinetic energy and momentum for your plane. There's some maths involved, but if you probably want to design your nozzle for back pressure somewhere between 50% and 90% of the maximum. You get your max thrust at the high end of the pressure range, but you don't want to optimise your nozzle for 100% of the available pressure, because as soon as the flow starts you'll be out of your ideal range. I'd start by looking at rocket nozzle equations on wikipedia and see where that takes you.
This guy's voice and accent are identical to a guy with a channel called Rationality Rules
This is some big brain shii
Ever tried v1
You should aim the thrust closer to the center of mass, like on the F100 "zero length launch" experiment: kzhead.info/sun/oq2moZWfo6CFl6s/bejne.html
but why does the plane look like the reaper UAV?
Use a swept back jet fighter design
shoulda found a way to put a gopro on the plane lol. crash woulda been crazy
So strange you aren't in Tom's featured channels list.
Well nvm I guess he fixed it.
Give the wings a little dihedral
It already has it
When people who have zero clue about aerodynamics try to build an airplane.
Lighten at the back not the front to hold the nose down
Mono wheel while wearing roller blades and two motors
Tom santon?
Now just put an aerospike nozzle
You need a proper rocker nozzle mate
"Feet", "PSI" ... how about "m" and "bar"?
Like Sisyphus, bound to hell
"TO THE MOON!" :crash:
liquid + heating = no pressure while in storage
why do walls not collapse? they are not bent by 90 degree lever
Hope you bought some CO2 certificates
Its amazing how such smart people make such stupid mistakes
multiengine plane in the FUTURE........and the Future is now...how is the new plane progressing ,,??...your audience awaits....just keep the flights away from brick buildings... Do you still ride your BIG wheel ??🚲🚲
