This is a fully autonomous replica of the SpaceX Falcon 9 capable of launch and landing on both the drone ship and at the DSC launch site. Just spawn the rocket at any location at DSC and the flight computers will do the rest. Once the rocket has completed its ascent and boost back burn, take control of the second stage to boost your payload into a higher trajectory. Just make sure to switch back to the booster before its entry and landing burns!

This craft is the latest in a series of rockets ultimately leading to a fully autonomous Starship, Superheavy and Chopstick system. Featuring a fully overhauled code base and working aerodynamics and grid-fins compared with my previous craft. As before, landing sites can be configured in the flight code (see notes). Next up will hopefully be a fully reusable falcon heavy to finalise the code structure allowing for multiple boosters to be controlled at once (or boosters and chopsticks…)!

NOTES:

-Payload is configurable up to 12T (Ideally keep the weight around this value)

-Can be launched from any location at DSC (Please do not launch at the Launch Pad Large for RTLS landings)

-To switch between landing locations, change the “DroneShipLanding” variable in the code to
0 = Return to Launch Site
1 = Drons Ship

-If switching crafts back to the booster, sometimes the landing site needs to be reset as a target for the entry burn to work properly (Do this when switching back from the second stage if the booster is not targeting anything!)

-Any problems please let me know in the comments

    But also breaking everything down into x and y components is super important.

    Just a quick example of how to break things down. Lets look at the boost back section. The rocket in this case is still falling back to earth. We can use gravity to estimate how much time we have before we hit the surface. Using this time and how far away we are from the launch pad in x (east/west) and y (North South) we can work out how fast we need to be going backwards in both these directaions. Then we can take these 2 speed values and combine them into a heading using simple triganometry angles. Then its just turn the engine on and set the heading to the calculated values and keep repeating this till the rocket has achieved the speeds we calculated
    i.e. while (Vrocket < Vcalculated)
    fire engines
    re calculate time in space
    re calculate required speeds based on distance and time
    re calculate heading
    set rocket to new heading

    once outside the loop turn engines off

    The reason to recalculate everything in the loop is everything will change very slightly as the time in space is going down and the rockets position and velocity are also changing. Then once this section of code has run the rocket can move on to the next section like entry burn.

    @SsubspacEJNO No I dont have a youtube channel. Got a model falcon heavy in the works with dual booster landings, then ill try make some simple craft that each do something simple in vizzy like hover, control position, scuicide burn etc... The most important thing to remember is the code is made in sections and is just a real world implementation of some maths equations or models. Have you programmed before? For this you need a basic idea of programming logic i.e. if statememts and itteration/sequencing

    @SupersonicRetroPropulsion thank you if you could make the videos and do you have a youtube channel? if you have one than channel name right now

    @SsubspacEJNO haha thanks! Im thinking of doing a vizzy tutorial series later on. If youd like I can send a mode detailed message on how Id start if i was learning again. The code is complex but its made up of many simpler sections which were built and tested individually on smaller rockets over a year or so. Its all about braking the end goal down into simpler processes

    @SupersonicRetroPropulsion I tried youtube and like I learned a bit of knowledge but nothing special and how can you say trial and error like the code is super complex

    @SsubspacEJNO Just lots of trial and error. Theres a few good youtube tutorials too. Start simple like writing a hoverslam script (not nearly as difficult as it sounds, just suvat and f=ma) and then add other elements like position controll etc...

    @LaunchRocketsForFood Orange and yellow still have not connection and my game is mobile version

    @CCCP0000001 trying to fix it but it’s a little tricky when i can’t get it to break. Would you mind telling me which colour part it is on this Colour Version. This version has more connections so let me know if it still doesn’t work. Also are you on mobile version or pc? Thanks for your patience!

    @AstrumY Thanks! I use the game camera tool but take screenshots instead. That way you can crop or composite images in any free editing tool. I used PSExpress. You can then edit the game files and swap out old photos for the edited ones.

    @LaunchRocketsForFood The outermost frame on either side of the first stage grid wing,not a big problem but if fix will be good

    @CCCP0000001 Hi which part is falling off? It’s working on my computer but let me know and I’ll try and fix it

    It seems that something that is not fixed will fall off during launch, hopefully you can update it in a future version
