Rocket Takeoff AND LANDING! - Matlab & Simulink Tutorial

This is a tutorial on how to perform a full flight simulation of a rocket taking off and landing. You will learn how a gravity turn works, the deorbit descent phase, boostback and entry burn, and controlling the pitch angle for a vertical touchdown.
It will be assumed that a single stage rocket takes off and lands i.e there is no stage seperation for this tutorial. You can then visualize it in FlightGear. If you do not have FlightGear, I also show you how to use MATLAB 3D Animation instead, which is just as good!
TIMESTAMPS:
00:31 - Intro and Theory
05:03 - Free Body Diagram of the Rocket
06:50 - Explaining the rocket flipping, re-entry, descent and touchdown
07:30 - Matlab Code Tutorial
08:30 - Simulink Model Tutorial
20:13 - Explaining simulation results
21:40 - Connecting the simulation to FlightGear
22:00 - Matlab 3D Animation (if you don't have FlightGear!)
22:51 - What the simulation looks like in FlightGear!
24:10 - Explaining the results / conclusion

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
@julianchee2894
@julianchee2894 Год назад
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.

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.

Yes you have to use simulink real time

Do rocket second stage ignite by it self or do they ignite on ground station? and how do separation work?
@VDEngineering
@VDEngineering 3 года назад
Seperation is done by releasing bolts which attach the stages. Second stage is turned on by flight computer.
