SpaceX inspired edf rocket part 2: Final assembly, tuning and maiden flight
Вставка
- Опубліковано 22 вер 2024
- This is the second part of my Spacex inspired edf rocket project where I assemble the final pieces of the rocket, tune the correct PID values and perform a maiden flight.
In order to find the correct PID values i had to build a rig that suspends the rocket in it's center of gravity and which allows for 2 degrees of freedom. I first tried to tune the PID values with the rocket suspended on a wire but this ended up working not so great like you can see in the video.
Once i got the right PID values dialed in, I first did like 10 hover tests inside (now i did try this out with the wire attached) before going outside to attempt a maiden flight. I build and painted the landing platform a day before the maiden flight and the paint was still a bit sticky. As a result of this the rocket stuck to the landing platform and tipped over. For the next attempt i put some baby powder on the platform to prevent it from sticking (which gave me some nice clouds when taking off ;-)
It turns out landing an orbital rocket booster (RC replica) isn't that easy.Cudos to you mr. Elon Musk ;-) I wanted to do some more test flights to try to stick the landing but unfortunatley the wind started picking up. However I'm still very happy with the results i managed to get out of it (in contradiction to what some people tought ;-)
Once the weather clears out again i will definitely try the landing bit again, I'm even thinking of adding a gps to the pixhawk flight computer and attempt an autonomous landing. We'll see.
For those of you who say an edf is not a rocket, you're right it's technically a single copter design in the shape of a (SpaceX) rocket. An edf really is the easiest and cheapest way to control the thrust to maintain a stable hover.
I wished i had the technology, knowledge and money to attempt to build a liquid fueled one.
I'm referring to "Spacex inspired" because i did use some general proportions from the falcon 9 rocket but had to make a lot of adjustments to turn it into a fully capable working rocket that's capable of hovering.

Wow that looks awsome and you've got it flying so well! Great work Brian
Thank you very much Tom! I’m a big fan of your channel. 😁👍
Omg tom stanton
I want a baseball canon
Too bad, rockets dont have propulsion in vacuum and these space agencies are faking it all.
@@idontcare7961 shut up flat earther
No words !! Awesome !!!!
Un piacere vederti qua
I am seriously impressed! Not only by the result so far but also by your structured approach. Great job!
Great job! FYI I found that iNav was much easier to tune than Arducopter for this sort of thing. I was never able to get my single copter flying well with Ardupilot but iNav was very stable with just a few minutes of tuning.
@rctestflight thanks man, I’ll definitely take a look at iNav, thanks for the tip. Btw i also love you channel, I watched a lot of your videos. You made me want to build a solar plane so bad haha 😂👍
Alexey chekurkov , with your skill in engineering and design you could probably build this guys anti gravity device. Many people have elvaluted his videos and cannot prove them fake. His videos are in Russian but some have transportation and full explanation of theory.
this is what i want to do in my spare time.
You made the world a million times better with this dude, thank you
*AMAZING WORK* Thumb up i am just for long time in RC Model Scene but that i have never see befor, very very nice.
Looking great from my rc perspective too, Great thing is you can dial it in, with almost infinate adjustment.
Landing geat needs some attention, id temporrly do a rc helecopters trainer style landing gear, till its set up.
Well I really appreciate spacex's struggle seeing your landing struggle with much simpler approach where forces involved are in small scale.
Am i the only one who doesnt know anything about this yet i watch it because i find it entertaining?
Damn you are so smart!! Hats off to you man!! Keep doing what your doing we need more brilliant minds like you nowadays!! It would be so cool to see it fly around like a rocket or sidewinder missle then land please do somthing like this in next video!! Well done man!!
he's in the shop again marlene, playin with those damn rockets again!
This is absolutely amazing! I've been working on a EDF VTVL vehicle too and really respect your work knowing how challenging this is! The fully functional legs are so satifying! It would be cool if you add some deployable fins on V2 so it can fly up and simulate landing
I remember when you first started this lol. It’s really cool. I’d recommend putting motors on the side near the top for added stability. Not sure how big of a job that would be coding wise, but it would definitely help for keeping it stable and help during landing.
That's actually amazing! The legs design is beautiful. Waiting for more updates.
Absolutely incredible! Amazing work.
You are a great inventive constructor with passion and commitment. Don't give up, you'll be great. I'm cheering for you.
Who is this? Why did I get a bell notification? Oh, never mind. This is some cool af stuff.
Same here 😊
I come here from un poco de todo,keep it up bro
Excellent effort and design .Nice work humanity reference.
Great project!! Looks great!
Add weigh to the lower position or move down the EDF or battery.
I fly RC airplane and when the plane is in hover and nose heavy start to oscillate the same way that your booster, so my advice is to add more wight in the lower position or remove weight from the upper position.
Good luck!!
Just like with the real thing, I was thinking "This will never work at all".
And just like with the real thing... I was wrong. :D
Nice work!
Elon : "Your Hired!"
I'm a genius too! I would like to ask you, can I be your Vice Chairman?
When quarantine make you more productive👍
I see a future SpaceXer, great job Brian, I was impressed with the gimbal mounted test stand, the rocket blew me away!
please youtube make this guy famous to inspire next gen engineers
Thanks man, appreciated 😊
Your wish has been granted, totally random bell notification for this vid, now subbed
Very creative and she looks beautiful. Excellent work!
It looks a lot like SpaceX when they were first trying to land a booster. A lot of falling over... They had a lot more explosion. lol. Looks great!
Really nice work... To be continued 😊
Just popped up on recommended videos. I'm not and RC Rocket guy but that was awesome, congrats on the project 😎👍
Thanks man 😁
Amazing job! Keep making
Omg I loved the ending trial and errors. Very cool.
Genius !!!!!!!!! If it were easy everyone would make it,
It take a special mind and fortitude.
Well done Bravo 💪😎
Wow!! Huge Respect for your engineering!!
Awesome! Great work Brain!
Great job 👍
Never give up is the key for success. Keep climbing. 🚀🚀
Really good......we need more people like you.congratulations
When I saw it on my recommendations, I've thought he's like Tom Stanton and here's Tom in the comment section hahahaha
Very nice.
Can not believe you don't have a million subs. Insane work!! You give so much inspiration!! Kids should be forced to see this. So damn cool!
Please check, the center of mass over and it's ratio over length. Great work Brian keep it up
Wow great work Brian!! 👏👏👏
Thanks Sergio!
Ooo I didn't knew you were going to make this thing fly, epic!
Well if the youtube thing doesn't pan out you have a bright future in engineering!
Excellent
You are talented enough to be inducted in to NASA/Space-X team. Good work and Good Luck.
Increíble proyecto, saludos desde Argentina 🇦🇷👍
i'll be honest. I expected a massive explosion when it fell on its side. This is really cool.
Wow! Great job!
I thought that such a stable EDF was not possible. Amazing.
What do you think of a "touch down" sensor to apply instantaneous brake on the EDF's ESC?
Ahahaha. I could "see" the resulting explosion when it toppled. Nice work in making this!
Very cool project!
Nice work! All those landing look so like space x in real life!!
HELLO BRO SAW YOUR CHANNEL FOR: [A LITTLE OF EVERYTHING], IT'S A LATIN CHANNEL, I LIKE IT, IT IS VERY ENTERTAINING TO SEE HOW YOU BUILD, YOU DO VERY INTERESTING THINGS, WHAT A GOOD VIBRA, GREETINGS FROM COLOMBIA...✌🏻
Keep going, you're almost there! Maybe griffins or engines for lateral thrust
Haha yes, unfortunately grid fins aren't that usefull at low speeds, but using compressed air thrusters might work to keep the rocket upright during landing.
This is amazing work and progress! I'm wondering, watching the videos, if you're trying to do too much manually. for instance, would a downward facing camera that's looking for the 'marker' of the landing pad be something that could assist with the landing. the computer could make faster adjustments I'd think. Also do you need thrust on the head of it? The first landing came in at an angle, there was a bit of a bounce and then it looked like the head momentum just kept going (makes sense, the base was 'stuck' as it was on the pad). If there was thrust at the head, I'd think a small amount would go a long way. That may make the design too complicated, but just my thoughts. Really well shot video, thankyou! Subscribed and looking forward to the next one!
Awesome work don't worry you will get it to work soon
Atlast my favourite video for which I was waiting for is out here 😎😎 thankx sir, you are an inspiration for young aerospace engineers 🙏🙏
Wow! It looks pretty awesome! And it is.
Thanks for the like!
Respect 10/10. That is epic design skills
Nice, awesome work.
Thanks very nice video i am waiting for this
I was about to ask what kind of rocket engine this is. This is still an impressive feat to keep it that stable.
wonderful garden
Keep up the good work! Don't give up!
Now that looks awesome!!!
Awesome work bro,it's really a motivation for hard work.
This is awesome Brian - great job. I wished we had found this before our attempted EDF Rocket build video we just posted. We are wanting to get rid of our parachute and go to a VTOL solution in our version 2 so this fantastic to see it's possible. Love your projects
That is cool.. I think u should add a slight spin to stabilize before landing
Great job man
great job...even Space X had few failures before they landed the booster successfully
Better than I was expecting this early.
This is awesome bro! Yes liquid is definitely expensive, but maybe u can try a mini sugar rocket? Just enough to launch like 20m since the focus is on the landing
Amazing Job!
1. Put a rocket engine at bottom. 2. Put landing legs at top of first stage. 3. After burn launch, eject capsule (parachute?) and use small gyro to flip first stage of rocket 180 degrees. 4. Now with landing legs down, use the landing motor to put her down. Piece of cake!
Don't give up dude..you nearly there
You may want to look into abandoning PID control for an inverse kinematic control loop using a kallman filter. You may find you have far better control and faster convergence and aquisition to the correction angles.
Thanks man, i'll take a look into that.
Impressive!
And also makes SpaceX all the more impressive 👏👏
Great. Nice garden btw!
Haha thanks man 😉👍
Great Job man.... Go on!!!
YOUR AWESOME DUDE
😎🤞🏼Great work!
Absolutely amazing! So much fun watching the hovering falcon 👍🏼
it may be bouncing on landing because of the flexiblility on the leg mechanism. Awesome solution for the air intake!!
Well done men!
excellent video, i really like the little test stand you built. looked very clean and professional.
Thanks Travis, nice to hear 😉👍
Nice attic shop!
Thanks man ;-)
Don't you think the head weight and its height is way too big with respect to the leg you provided for the landing?
You may use a mechanical gyroscope in rockets for stabilization and landing correction.
Great job dude! That's Awesome, oh AND COOL FREAKING YARD!!
Maybe some type of shock absorbers attached to the landing legs, let them give a bit on side that hits first yet not too much. This may allow the other legs to get contact and stabilize the attempts.
Yes this is a good idea worth condidering, but this will add some complexity (and weight) to the design.
Great work
You must present this to spacex asap
good job. I know how hard it is. hug from Brazil.
Would love to have the landing gear for my falcon9 motor rocket I'm 3d printing soon. This is awesome 👍 great job!!
Love this project. Looking forward to more videos
Amazing work so far! top
Great job! I will wait for a successful landing
Vooreerst PROFICIAT voor deze prestatie.
Ik had eerlijk een beetje mijn twijfels of hij zou vliegen, hopelijk is ze nog in zijn geheel om volgende maand eens een indoor demo te geven. ( ? 18/10 )
Landen is nog altijd het moeilijkste maneuver
Haha merci Walter. Om eerlijk te zijn begon ik ook te twijfelen of hij wel zou vliegen 😅 Ik had in het begin veel problemen om de juiste PID parameters te vinden maar heb deze na het bouwen van een gestel (dat hem vasthoud in zijn CG en 2 vrijheidsgraden van beweging heeft) uiteindelijk gevonden. Ik ga hem zeker meenemen naar indoor, dit zou geen probleem moeten zijn. De meeste onderdelen zijn snap-fit bevestigd en komen gewoon los bij ne crash. De neus is bevestigd met witte ductape en schuift er gewoon uit wanneer hij crasht. Landen is inderdaad het moeilijkste haha. het minste dat hij nog wat snelheid heeft in een bepaalde richting bij het landen valt hij omver. Daar moeten we nog iets op vinden 😉👍
Very impressive!
I like that you run to try to catch it every time it falls...but never get there in time :D
I didn't catch it once haha😅. I stood a bit further because I didn't want to ruin the shot 😁
I just gave up on trying to catch it in the end haha, almost all parts are snapfit and can be pushed back after a crash, i just had to replace one leg servo arm once.
Wow, this is really cool man! Congratulations !!
Keep up the good work ,
Very inspiring vedio . dont stop your effort till u land it .
