you should really make at least a couple of those rocket motors have a second stage. it will already be mostly up to speed and a couple of them could really give you some extra alt.
Hi, I would just like to mention that after the engine burns, the weight is still shifted a bit because the propellant in the engine burns away as it is being fired. Hope this helps a little bit!
That’s what I was thinking, if there were some way to fire the rockets while it was flying, fire half the engines to take off, and the other half when they die out, won’t go faster but will fly twice as far.
@@alphagt62 your idea would be easy to achieve. Time the burn time of a particular type engine, then program a prototype board like an arduino and a relay to ignite each engine as they burn. I don't think the combination would add to much weight.
At 10:34 you say: " Even though we had more than twice the thrust, we didn't have twice the speed" and you wouldn't have. There are several factors, but the main one is that the drag quadruples when the speed doubles (Fd=0,5*ro*V^2 *S*Cd), so if all of the other factors would be omitted you should only go about 40% quicker.
You think that would be kind of common knowledge for somebody building something like this. Twice the power does not equal twice the speed. He probably just was telling us he already do that is my guess. God if it was that easy we would be able to go light speed pretty easily. I play around with model rockets when I was a kid and now RC cars also. It amazes me how far they come. I've always wanted to do what this guy is doing now I don't have to waste my money and you can just watch this.
The quadruple effect is a rule of thumb, it doesn't matter for subsonic speeds but damn there's a reason why propeller planes won't legitimately break the sound barrier
yes!!! while I was hearing that line i was like "don't you need four times the thrust to go twice the speed?? I wonder if someone in the comment section caught that too! and here you go!🤣
On a short span (low aspect ratio) plane a rudder does not do much for better curve coordination. The aerodynamics of this design are pretty crude and the wing loading is high. That's the reason for the poor gliding performance.
@@NorfolkTrailRiding Not really funny, considering that by their very nature gliders must be aerodynamically efficient designs. Combine that with the more and more perfected use of nature's powers and you get that result.
Here’s a quick tip- drag can easily be lowered by increasing the angle of the wings. This does lower lift, but at the thrust to weight ratio that you have it should not be too big of an issue. You could also look into specialised aerofoils if you want to pull as much speed out of this plane as possible.
I suspect the GPS is only giving you ground speed - which is only accurate if you were flying horizontally. It looks like in the initial phase, you were flying with a high incline so the actual speed would have been more than the ground speed. If you flew straight up, the GPS would record a very low lateral speed.
@@TheKamiBunny To get velocity, you'll have to integrate the acceleration over time which introduces a lot of errors due to the noise from the accelerometers. In theory yes, in practice this won't work well. If you mean getting the angle of incline - then you'll need some sort of angle estimation, which could work (assuming you include gyros) but due to latency in the process, the computation might be more complex than possible for a cheap small device like that.
The joy and passion that is a large part of video (not mentioning the inevitable frustration) tells me that succeed or fail any one project isn't going to change how much you all love your work. Great vid!
I hope soon enough he gets a rocket to an altitude acceding 2,640 km (with a working camera) so we can see the curvature of the Earth. That would be amazing :)
For your aerodynamics mock test try running the motor blowing air over the body while you contain the smoke. Pipe it out using a thin hose with a needle attached at the end, seemed to work better for me when it came to seeing how the air flows (2:30)
Fun fact, when building a smoke tunnel it works better to have a basic straight chamber and to have suction out the back. This results in the smoke being more stable and less turbulent than when blown from the front. Keep up the awesome content! Love watching these projects
@@LameCorvette javelin missile almost, that's pretty much what it is, uses rocket engine to fire it up and then it glides down, if he can make the wings pop out then he could fire it off of his shoulder.
Something to keep in mind, a GPS speedometer like that does very poorly measuring instantaneous velocity. You might have ended up considerably faster at the end of the boost phase than your speedometer indicated, just because the distance-and-time measurements might well have checked both sides of the peak.
Exactly. Once you exceed the pitch speed of the EDFs (compensated for the intake), they're just adding drag. A folding propeller is definitely the way to go, and cut the throttle and let it fold before lighting the rockets.
You can remove the loose powder charge -or- get the 2nd stage ones denoted by a "0" as the last number. 1st #= Thrust, 2nd #= Delay, 3rd #= Ejection Charge.
Which makes it against the rules for any NAR or Tripoli sanctioned launch, where the rules state the launch angle can not be more than 20degs off the vertical.
For the newbies to rocketry, thrust is always designated in pounds-force (lbf.) or newtons (N), and never in kilograms (kg) because that is a unit of mass, not force.
Move front wings back to increase lift. It will be more difficult to fly but that's not what those motors were designed for. Nowadays with all the technology right at your fingertips, sometimes it just takes trial and error to get the best results. You could also use zero delay motors and stage them so the D's fire while in the air. You could also launch directly vertical which should increase your flight time ( if you could control it!).
I built one 42 years ago. The small wings caused the rocket to spiral in a large circle. I USED C-6 ENGINE. It would glide down after engine burn. I also made the first drag racer using B and C engines depending on the distance available. I would use 10 pound fishing line as the guild. If no guild was used the drag racer would run wild. I used a 2x4 and cut it down and added free wheels on steel axels drilled through the 2x4. Used eyelet screws as guild also tried rocket tube guilds.
7:20 - THAT'S NOT BORING! I love to see well thought out testing done, and I suspect that others don't mind it as much as you might think... Getting to see your entire process is highly valuable to me, and I loved that you included it in this edit :)
Did a very rudimentary version of this back in the late 90’s. A single C-motor with an 18 inch wingspan. Motor was on a nacelle under the nose.The thrust swung the wings back into a delta configuration and after the motor ejected it lightened the nose enough to pitch up as a rubber band pulled the wings out like an F-14. From there it glided back down unguided to a soft low speed landing. Crude but fun!
This is so amazing! Also I kinda want to see some high-altitude vertical runs with this kind of rocked engines. Maybe even some space shuttle style attached boosters.
Want to go fast? Add a large core-burner* in the middle and set it to ignite one second into the flight. The wings had better be attached well or you _will_ rip them off. *The engines you are using are end-burners. Core burners have much less burn time but massively more thrust, that's why you delay ignition until the rocket/plane is underway. I've not only torn fins off but had rockets just tear themselves apart from too much thrust from a standing start.
I’m amazed you were able to ignite all six motors using the electric wire igniters, those things always had a bad reliability issue in igniting multiple engines. Great job.
I had a 2 engine Saturn IB model that used two C engines that I attempted to fly when I was young back in 1974. It only flew once because only one of the two engines ignited. It somersaulted and landed flat on it's side breaking one of the fins. I couldn't find the part that broke off and didn't dare fly it again. I should have used the one D engine instead. It could use either 1 D or 2 Cs. My hat's off to you for getting all six engines to ignite.
I really enjoyed this. When I was a kid back in the 70's my friends and I designed our own rockets and used the Estes motors, but we only could dream of wonderful projects like this. Super work! New subscriber from Texas!
After watching the rocket engines destroy so many of your precious prototypes it really made me smile seeing this one come in for a survivable landing really paying homage to all the work that went into the previous martyrs
Nice to see you are getting ahead with aeronautics🤩 it will get more and more interesting further you go! Rocket=go for height, plate=manoeuvre and glide. A general equation using solid fuel propulsion is twice the thrust double the altitude. And with C to G cartridge you were well on your way!! What was you wet weight??
Ikan berapi [Ali B.P] The V1 was NOT a rocket,it was a Ram Jet,the Flying Bomb",the V2 was a liquid fueled ROCKET,and the Bachem Ba 349 "Natter",get your history right !!!!!!!!
Once upon a time, Estes used to produce E and F rocket glider engines which had no ejection charge and were plugged to prevent anything being thrown forward out of the engine. They used a blue label and were labeled E12-P iirc.
How did you learn of this aircraft design stuff? And how can I go about doing the same? If only there was a platform that pulls together educational resources in one place, so that I can level up my skills and learn about subjects I care about. That would be really helpful!
He said it at the end of the video. Just kidding. Well just find something you want to do and do it. Search on internet to help you and you'll be super proud when your thing will work. Sometime these projects can take months even years but the amount of things you learned at the end is huge !
I've not built an actual RC plane (yet!) but I'm sure watching channels like FliteTest, Peter Sripol, and more of this channel will help you learn stuff, along with looking at forums, and just trying to build it yourself to learn from your mistakes. Most of the skills I've learned so far were about 50% TH-cam, 20% forums, and 30% doing.
If you are going to use EDF’s on the wings and then hit the rockets you may consider some canards on the nose to keep the nose down when the extra thrust hits. Another idea is there’s other brands of rocket engines that have a slower ramp up burn that might be a good ramp up
The Estes engines come in a variant with a -0 at the end, the last number represents the delay between the engine running out of fuel and the parachute jettison charge. So a motor such with a -0 at the end will have no charge
I just want to say a spitfire has rounded wings not squared off. The rounded wings were also the cause of them getting stuck in flat spins that most beginner pilots wouldn’t know how to get out of.
The two stage ideas others mentioned is decent, but you’d still be using up a stage to overcome inertia at liftoff. I think the best answer would be to build an rc plane, perhaps a scale model of a hypersonic ramjet design, and build in two rocket stages that can be ignited remotely in level flight.
You should design it so the chute ejection charge of the engines dislodges them from the body, giving the plane tiny amounts more thrust while dropping the weight so you can hopefully glide it more after

Be you😊 (BTW I didn't create this quote I just want to spread positivity🙂)
Adding a booster board behind the rocket might give it a bit of a boost while launching just like how regular rockets use the ground or there platform for the push off boost
Prob should use a cap or such to provide the quick burst of power needed to ignite the engines when in flight after you get to where you want to be or just need that extra speed boost...maybe also add tiny rockets to attach to your wings if your really crazy
LW-PLA would be nice for that nose cone and maybe the wings. It foams making it harder to prevent stringing with but better for things that don't need to be super strong or are given strength by their surface area and design rather than brute forcing stronger materials like the nose cone and wings.
Dont expect twice the speed from twice the trust. Air resistance scales with the square of speed, thus you need 4 times the trust to get twice the speed.
Looks like the 60s Dyna-Soar prototype! Remember that there's a significant vertical component to your actual airspeed, not only the speed scrubbed by a high takeoff angle; those simple GPS units only measure your speed parallel to the ground. Think of it like a 30 60 90 triangle with the shortest side against the ground. That is the only side of the triangle the GPS you have measured, which if used on an R/C car is completely fine. However, your airspeed was most likely MUCH higher than that! You need a combo GPS/altimeter with a fast refresh rate (like a Pixhawk 4 or better ~$200) to track your flight path in 3 dimensions with respect to time. Pixhawk also has pitot tubes and modules, although the're likely a bit heavy for that. Awesome stuff, though!
Could have used the Estes plugged engines that don’t have an ejection charge. Credit to you for the thought that you have put into this , great video 👍
My father bought me a sr71 model rocket when I was really young. At launch it flew about 15' strait up then turned 90° and flew horizontal above everyone's head. I thought it was the coolest thing ever but my dad thought it was a type of failure.... I still think it did exactly what I wanted it to do.
Built a rocket plane out of a triangle fedex tube and foam board that’s used for art projects and displays, made a nose cone from a styrofoam block at a triangular shape to match the body, used 5 d engines and 4 c engines. Everything wired right, it took off like crazy, it went up 1000 ft turned as it loops and came in like the space shuttle, it was awesome. Used the same fuselage and everything 4 times until hit a tree
Hugely impressed by your enthusiasm, engineering skills and that you are young enough to have the necessary reflexes to control something moving that fast!
Great project. Personally I don't like the idea of using edf power though. It'll be really heavy for the thrust you'll gain. Consider a small motor/prop up front instead
Drag is the enemy of speed and increases with the square of that speed. I’d try to put one large edf in your fuselage and divert the thrust around the rocket motors. Something like a Harrier maybe.
Excellent video. I commend him for doing what most young people don't do. Take a break from video games to do some fun and educational projects. What surprises me is how so many young people aren't in tune with the world around them, yet most have access to the internet.
Very nice. Can't wait to see where this project leads. Shuttle booster platform, maybe? More than enough Newtons available to lift the lot'. And, if we're talkin' being cheeky here. You could port the ejection charge gasses from the booster motors to ignite the shuttle motor.
you can make the plane like a ramjet, the rocket motors get you up to speed and then that pushes air through a larger rocket candy rocket to give it more oxygen so it gives you more thrust

2 stages, one to get off the ground and another to rip the wings off

Make remote controllable stage separation and re-ignition.

Cant we just use both?
Well it will be much more speedy when crusing

The "Careful Now" decal is the best understatement.
I notice whenever you make a turn it drops like a rock, how about fitting a rudder to stop it slipping/falling and losing altitude on each turn.
Already has 2
It has 2 vertical stabilizers but no rudder.

Amazing! You kinda sound like georgenotfound
The Estes engines come in a variant with a -0 at the end, the last number represents the delay between the engine running out of fuel and the parachute jettison charge. So a motor such with a -0 at the end will have no charge
This project plane looks like a mix between a v1 rocket ww2 and a Japanese ohka suiscide bomber

AGAIN,the V1 was NOT a ROCKET it was a RAM JET,the V2 was a ROCKET !!!! If you don't know go research !!!!!!!!

Thank You for your kind words,and Thanks to your country men for their part they played and played well !!!!!!!
I just want to say a spitfire has rounded wings not squared off. The rounded wings were also the cause of them getting stuck in flat spins that most beginner pilots wouldn’t know how to get out of.
Here's how many people saw the rocket plane do a barrel roll
The two stage ideas others mentioned is decent, but you’d still be using up a stage to overcome inertia at liftoff. I think the best answer would be to build an rc plane, perhaps a scale model of a hypersonic ramjet design, and build in two rocket stages that can be ignited remotely in level flight.
"Helper" Mike. lol
You should design it so the chute ejection charge of the engines dislodges them from the body, giving the plane tiny amounts more thrust while dropping the weight so you can hopefully glide it more after

(BTW I didn't create this quote I just want to spread positivity🙂)
Adding a booster board behind the rocket might give it a bit of a boost while launching just like how regular rockets use the ground or there platform for the push off boost
Here in the US you can't have controls on model rocket engine's. Then it's called a guided missile.
One place where the UK is less restrictive lol
You are completely incorrect. Stop spreading misinformation.
There are even ready-to-fly KITS for this.
Prob should use a cap or such to provide the quick burst of power needed to ignite the engines when in flight after you get to where you want to be or just need that extra speed boost...maybe also add tiny rockets to attach to your wings if your really crazy
You need to put a blast plate on the launch rail.. gives the motors way more kick from the start of the launch
LW-PLA would be nice for that nose cone and maybe the wings. It foams making it harder to prevent stringing with but better for things that don't need to be super strong or are given strength by their surface area and design rather than brute forcing stronger materials like the nose cone and wings.
Dont expect twice the speed from twice the trust.
Air resistance scales with the square of speed, thus you need 4 times the trust to get twice the speed.
OK, I have to say, I have watched a couple DIYer's and this is one of the best flying I've seen so far. I think you have something there.
I’ve been building these since I was 6 I’m 32 now. Brings back fun memories.
You can buy rocket motors that are all thrust but they do have a reverse charge to ignite the 2nd stage of a two stage rocket
Looks like the 60s Dyna-Soar prototype! Remember that there's a significant vertical component to your actual airspeed, not only the speed scrubbed by a high takeoff angle; those simple GPS units only measure your speed parallel to the ground. Think of it like a 30 60 90 triangle with the shortest side against the ground. That is the only side of the triangle the GPS you have measured, which if used on an R/C car is completely fine. However, your airspeed was most likely MUCH higher than that! You need a combo GPS/altimeter with a fast refresh rate (like a Pixhawk 4 or better ~$200) to track your flight path in 3 dimensions with respect to time. Pixhawk also has pitot tubes and modules, although the're likely a bit heavy for that. Awesome stuff, though!
In the UK you can get a G80 , thats a 32mm motor with 8KG thrust, a minimum diameter rocket would achieve mach 1, use that on your next projext
Could have used the Estes plugged engines that don’t have an ejection charge. Credit to you for the thought that you have put into this , great video 👍
My father bought me a sr71 model rocket when I was really young. At launch it flew about 15' strait up then turned 90° and flew horizontal above everyone's head. I thought it was the coolest thing ever but my dad thought it was a type of failure.... I still think it did exactly what I wanted it to do.
I used build rockets like that back in the 80s… this totally reminds me of my childhood. Funny they still sell the same rocket engines.
Core for thrust and end burners for distance maybe a strobe motor for effects would be epic
Built a rocket plane out of a triangle fedex tube and foam board that’s used for art projects and displays, made a nose cone from a styrofoam block at a triangular shape to match the body, used 5 d engines and 4 c engines. Everything wired right, it took off like crazy, it went up 1000 ft turned as it loops and came in like the space shuttle, it was awesome. Used the same fuselage and everything 4 times until hit a tree
FYI- Estes makes rocket engines without parachute ejection charges. They are made for multi stage rockets.
Hugely impressed by your enthusiasm, engineering skills and that you are young enough to have the necessary reflexes to control something moving that fast!
Finally someone that has the lift off ramp correct
Great project. Personally I don't like the idea of using edf power though. It'll be really heavy for the thrust you'll gain. Consider a small motor/prop up front instead
Drag is the enemy of speed and increases with the square of that speed. I’d try to put one large edf in your fuselage and divert the thrust around the rocket motors. Something like a Harrier maybe.
Check your "cg" with spent egn's in place. Next. Research sugar rocket, & maybe add drop away rocket sled.just a thought
Excellent video. I commend him for doing what most young people don't do. Take a break from video games to do some fun and educational projects. What surprises me is how so many young people aren't in tune with the world around them, yet most have access to the internet.
Very nice. Can't wait to see where this project leads.
Shuttle booster platform, maybe?
More than enough Newtons available to lift the lot'.
And, if we're talkin' being cheeky here.
You could port the ejection charge gasses from the booster motors to ignite the shuttle motor.
You should 3-D print a windtunnel so you can test smaller rockets or aircraft frames
you can make the plane like a ramjet,
the rocket motors get you up to speed and then
that pushes air through a larger rocket candy rocket to give it more oxygen so it gives you more thrust
Share more recognition and exposure with your helper. You'll be rewarded with much more interest and loyalty from him.
That second flight was very awesome !
