ENGLISH:
This video is a summary of my master's degree thesis in aerospace engineering from Università degli Studi di Palermo (Italy).
Rockets spin about their longitudinal axis due to imperfect alignments in construction. This behavior could be a problem for telemetric systems or when guidance control on the other two axes are used.
In my thesis I designed, made and tested an automatic control system to negate the angular roll speed of a model rocket.
The system uses two control fins (aerodynamic control) moved by a flight computer equipped with a 3DOF gyroscope, an accelerometer and an atmospheric pressure sensor. I entirely scratch built this flight computer: designing the electronics, creating custom printed circuit boards and programming in C language. The code contain also two digital Kalman filters which compute an optimal estimation of the state-space from sensor data.
To design the digital controller and to predict the dynamic behavior of the entire rocket I implemented in Matlab / Simulink a 6 degree of freedom mathematical model. All aerodynamic parameters where estimated with real test flight data or with McDonnell Douglas Digital DATCOM Fortran code (a program which uses semi-empirical methods).
I also designed and built the solid rocket motor from a commercial combustion chamber, machinging a custom exhaust nozzle.
ITALIANO:
Questo video riassume la tesi che ho realizzato per conseguire la Laurea Magistrale in Ingegneria Aerospaziale con votazione di 110/110 e lode presso l'Università degli Studi di Palermo.
I razzi tendono a ruotare spontaneamente intorno all'asse longitudinale a causa di imperfezioni costruttive. Ciò è un problema quando sono imbarcati sistemi di guida che agiscono sui restanti assi o dispositivi quali antenne telemetriche o ricevitori GPS.
La tesi consiste nel progetto, nella costruzione e nella realizzazione di un sistema automatico di controllo attivo del rollio che annulli la velocità angolare di un modello di razzo.
Il sistema utilizza due alette mobili mosse da un computer di bordo equipaggiato con un giroscopio a tre assi, un accelerometro e un sensore di pressione atmosferica.
Il computer di bordo è stato da me completamente progettato e costruito, disegnando lo schema elettrico, realizzando il circuito stampato e programmando il microcontrollore in linguaggio C. Il software contiene due filtri di Kalman che permettono di ricostruire lo spazio di stato con i dati provenienti dai sensori.
Il progetto del controllore e lo studio del comportamento dinamico del razzo è stato eseguito implementando in ambiente Matlab / Simulink un modello matematico a 6 gradi di libertà. Tutte le caratteristiche aerodinamiche sono state stimate a partire da test in volo del razzo o utilizzando il software Digital DATCOM creato della McDonnell Douglas che utilizza metodi semiempirici.
Anche il motore a razzo è stato da me progettato e realizzato a partire da una camera di combustione commerciale. - วิทยาศาสตร์และเทคโนโลยี
and I am sitting here developing a calculator in C++...
hahahah
XenoContact that’s still cool
Hhhhhhhhhh funny 😂
😂😂😂
still better, im just copy calculator code in python
It's not good, it's VERY good!!! Great engineering!
Fantastic! I love seeing rocket stabilization projects! Keep up the awesome work, thanks for sharing.
One of the coolest things I have seen on a while! Excellent!
Agreed, I am working on something similar!
@@jmspaceR are you ?
Wow that's a really nice project. Top marks,
Ignore all the mean comments, this is a great project for a master thesis. Hope you were given a good grade.
People ignore the fact you did much of it from scratch, even designing the PCB!
People telling this exists in RC airplanes . Well, you think kids designed those? ENGINEERS design them.
Impressive!
You are very fortunate to get to do this.
I’m doing a project similar to this for my IB personal project. Looks epic !
I'm impressed!!! well done!
nice design and programming
Hey , great video. I'd like to read your thesis/any publications that you published for this. Thanks!
Well done, I have been trying to solve that problem. You really helped me.
I love this side of youtube, bravo btw! Or in your language bellissima!
Congratulations!
Very nice project!
you are awesome i hope you are paid well for your achievements
Dude that was awesome!!!!
Does this increase altitude? What other control does it give you other than not making it rotate? Amazing work.
wow that was pretty amazing!
Genius!!! Hello from Mauritius!
Love this design! When can we see a composite motor with 35-50lbs of high energy propellant in a slim rocket design and onboard camera?
Very impressive!
Felicitaciones! :)
Can you explain more about the control reversal effect of the canards ? I notice that the fin can spins freely and Jim Jarvis also uses it on his roll controlled rocket. I can’t find much information online regarding control reversal and why it occurs on roll controlled model rockets with no freely rotating fin can.
complimenti, fighissimo!!!
Great stuff.
Hope the University gave you 10/10.
Awesome job! I'm starting to study control and dynamics, I'd love to read your thesis! would it be possible?
I know this is from a while ago, but did you have to use your IMU to integrate for vertical speed and feed that into your PID controller (cause I'm presuming that the PID gains would vary by a decent amount by airspeed)? Let me know if I need to rephrase my question.
Beautiful
Thanks
Well done and great result! Where can I get more details?
I knew it was possible to do but have never seen it in action it worked beautifully,
is it possible to make a design were there is four controlable fins?
Awesome, work please add some more videos on canard control actuation system with detailed explain about that.
U have done ar great work !!! i am really impressed, can u share ur thesis and the report of this project i want read that
Bravo, What type of propellant? AP base? Nice work on roll control...
Cool.....thumbs up for for rocket view!!!
Well done! Not a huge market for it but I’m sure you could sell it in kit form.
Thanks.
Of course! But it becames more difficult = more time needed
very nice i fly high power rockets and would love to buy one of those systems
Well done
good job
I hope you got your degree!
It's an old story & known to all in the field!!
Wow this is very impressive. How complicated was it to design the computer? Pretty incredible you where able to understand all these different concepts at once. I was thinking about using a Raspberry PI Zero to record flight data for a first project.
raspi's are good enough. he probably just used some popular microcontroller with tons of documentation and just rewired based on his needs. not easy without embedded electronics knowledge
Hello, thank you for your good video. I want to make a small guided rocket. I wanted to know what I should do to make a guidance kit that can guide the rocket to a certain point. Do you have any training in this field?
I would like to make a sample like you, of course, not with a war cap 😂 but a cap with paint inside
Fantastic! If they didn't give you a pass mark, I bet I know how you would 'take them out'!
Very good
Great job, who is the name of your web?.
Ciao Adriano, dove posso leggere la tua tesi? Ti prego inviamela :D
I gotta put one in my rockets! They spin like crazy!
Which component is used to transmit the power to fins..is it servo motor or anything else??
cool video and could i read your tesis?
Great control system design! congratulations! Do you have a webpage with the details to build it? e.g. what did you use as propeller and details of the PID parameters you used to control the servos in closed loop based on the gyro data? Which is the gyro board you used? Thank you in advance!
I would be also interested to know which sampling time you used for your closed loop control system....thx!
@@juancarlosabad3298 He wrote a paper. Look for the paper
Nice !!!
Great video!! Your Awsomely intelligent, you should market the system!!! I'd buy!!! I'm 56 and still gluing balsa wood fins on paper towel tubes! Lol... I built a tree fort once when I was a kid. It fell out of the tree... 😳
Which fuel you have used
Ciao Adriano,
è possibile poter leggere la tua tesi? Sono uno studente di Ingegneria Meccanica di Roma (in futuro vorrei continuare con Aeronautica) e mi interessa molto il settore missilistico.
mitico
Hello sir! I am an undergraduate electrical and computer engineering student. Can i get in contact with you please?
Wow! 8 years ago
nice
How old were you when you got your degree?
Can arduino be used for tvc?
please, l need to know Names of books about made the rocket
Is this open source?
Where can I buy the carbon fiber material to make fins for Sport Rocketry Competition...?
McMaster Carr
Nice
great
Just wow...
Can you share the code to learn from it. You have IMU on this project.
Surely you would want the rocket to spin to maintain a more accurate trajectory? Like a rifle barrel is rifled to create spin on the bullet to prevent it straying? The rocket would then have equal inertia acting on all angles during the climb?
Ho utilizzato un razzo in kit: il modello si chiama "intruder", la marca è PML (public missiles). Il kit è però stato pesantemente modificato.
Grazie.
Il classico KNO3/zucchero (destrosio)
ITS GOOD BUT I WANT TO KNOW HOW TO MAKE DUDE COULD U HELP IN IT
Pretty nice, now it's 5 years later, can do this with $8 flight controller (F1/F3/F4) and $5 servo.
This is how it is supposed to work.
Is the code open source ?
genuis
Why electronic spin stabilization when you can mechanically control it without any electronics.
Good
?Can i request the source code sir
Are you still online? I contacted via e-mail.
hi.. veery impressive too.. azhar
what propelant and oxidizer did you use?
+Luka Luka Same stuff I use in high powered, same stuff in the space shuttle solid boosters, ammonium perchlorate and aluminum powder. Stay safe ;)
No, it's rocket candy - KNO3 with sugar.
OR... you could use analog like the older sidewinders
Could you share the code 😎 Thankyou ❤️
it must upgradet to a gps target finding rocket
Looks like an oto melera dart strales system
does it go higher if i does not spin?
No, Its probably made for capturing aerial video or for controlling the direction of it
Yes. A little bit away. More of the potential energy is transformed into translational kinetic energy instead of being wasted on rotational kinetic energy.
EDM + ENGINEERING✊
y the music man
try to use ardupilot with gps module, define a route and hit a specific target
xaxaxaxaxaxa maybe if the missile go in a great altitude and open wings and then gps guide it to the target like a plane.
This is only roll control.
Bad a_s Brother : )
and is it possible to program so that the missile hits the target?
Make it 'target' drones
okay the mechanical construction is not that hard i guess. and every engineer knows some C nowadays, seems doable.. but then how the hell do you design a PCB and do other EE engineering related stuff ?
Its actually very easy.
You can order custom PCB's from china for next to nothing. Pcb's are designed in altium, it even routes for you if you're not picky.

I was making a rocket it was successful
