i am getting multiple curves in scope block , how can i resolve it, , i have been provided with thrust time curve and mass flow rate vs time curve , i calclated mass values and thrust vaklues from it , how can t be done?
My iteration stops at around t=100 sec. did you modify your code after the video but before you ran your simulation? My height drops drastically around t=75
Can u please tell me That thrust funtion and all, Why I am not getting %# codegen directly after I open script by Matlab function ( Thrust, Pitch cmd and last one) I did same as u did, but i am not getting that %# codegen, please let me know what to do with this
But how do you transfer all that modulation which you did on simulink and matlab to the flight micro controller. Do you have to convert to C++ program before transferring the code to the micro controller. Quite new to this field.
If the rocket is flying with a flight path angle gamma during the launch, why isn’t the altitude h*sin(gamma) ? That was done for dx/dt and dh/dt to resolve vertical and down range velocity
Oh never mind. I see it now. The height h is directly pulled from the dh/dt block in which it’s already integrated by v*sin(gamma). The way I’m structuring my simulator is a little different.
My simulation stops at t = 150 s as my height goes to zero. Can you suggest me how to solve this problem, i tried few things but still its not giving required results.
Bro , I told you a while ago that I wanted to communicate with you and you told me that I can do that for 35 dollars / hour, how can I send money to you to complete the procedure
Vin, you finally did it bro. Good job.
Love from India ❤️
this is next level stuff mate ! awesome you put it out there for free. Thanks!!
Thank you so much, you are a good person and have manners, God bless you.
thank you for posting this amazing work!
God bless you for that. This video is just wonderful, it helped me a lot.
Man this is awesome. Thanks for that
This is amazing. Thank you so much
for this rocket simulation do you have to use the latest version of MATLAB? I'm using MATLAB version 2013 can't simulate the graph
tht from where?

Yes it stops when height is near 0
Did you solve the problem?
Cool video. Do you have any plans to make a helicopter flight simulation in Simulink?
Yes
Cool! We are waiting for it)
Nicely explained!
great! looking forward for transferring the flight path to a home made rocket :')
Love your videos brother, valuable for me. Also can u recommend any MATLAB and ANSYS course for aerospace engineering?
Will you make a similar tutorial for 6DOF at some point in the future ?
If I have time to
@@VDEngineering thank you
hello there
if i want to ask you a couple of question about nozzles, where should i put them ?
in the last nozzle video ?
thanks

Yes you have to use simulink real time
is there something to work with in python ?
How can we plan for a model rocket? For simpler and less altitude?
If the rocket is flying with a flight path angle gamma during the launch, why isn’t the altitude h*sin(gamma) ? That was done for dx/dt and dh/dt to resolve vertical and down range velocity
Oh never mind. I see it now. The height h is directly pulled from the dh/dt block in which it’s already integrated by v*sin(gamma). The way I’m structuring my simulator is a little different.
Have you tried your way?? and is it working??@@julianchee2894
can u please tell me if we can launch two rockets together in flight gear using same "fg bat" file ??? thanks in advance.... love ur vdos bro.... :)
Hello, that's not possible, only one object can be used at once
@@VDEngineering Thakyou sooo much VD. :)
Do you recommend using the aerospace blockset to compute the state vectors ?
sure
perfect 💙
if you are simulating ascent from mars, do you use g=3.71 or g=9.81 (calculating burn time)?
I didn't' see you using from block for tht and x.
exactly, and if you run like that it gives an error (missing from tht and x)
I have two questions. Is the rocket the same mathematical model as the missile? Can a missile land vertically with only one solid engine?
Great job! Very interesting.
Can you share the simulink file if possible im getting some errors
Sir is there any possibility to do the helicopter seat ejection system in matlab .....
How to upgrade this to 6DOF?
What the difference than this tutorial with your other video of dynamic control of launch vehicle?
Did you share it as a GitHub repository?
Do rocket second stage ignite by it self or do they ignite on ground station? and how do separation work?
Seperation is done by releasing bolts which attach the stages. Second stage is turned on by flight computer.
How about repeating this using JSBSim instead of MatLab ?
Should be possible, I never used jsbsim before
@@VDEngineering It's a pretty neat simulator. It is one of the simulators that Flightgear uses.
hello, does this simulation still work? I went to test in my matlab and it gave an error
My simulation stops at t = 150 s as my height goes to zero. Can you suggest me how to solve this problem, i tried few things but still its not giving required results.
Did you solve the problem?
Can you recommend some Matlab courses for aerospace engineering?
More specific please
Is there a chance that you could upload the model to your github page? I did everything I can but something is going wrong...
Use digital clock instead of clock if you're on newer Matlab versions. And remove the PID control stuff

Can you tell us about books you read about rocket controls please?
Read NASA papers from NTRS website.
What is the Jy term in the Pitch Moment equation?
Moment of inertia in y axis
What does the Flag stad for??
It's a boolean
Great!
What is the R_E ?
Earth radius 6871km
I am been interested in this field, could you help me sir
