[video] SpaceX Falcon 9R landing
Hi everyone, I'm making an automatic landing rocket Falcon 9R Dev for three days and that's the result:
https://www.youtube.com/watch?v=MiQUewt-56k
I started like SpaceX - from simple VTOL Grasshopper, which only could kill any velocity and land anywhere on trajectory Yesterday I made an algorithm for engine servo which could sometimes land Grasshopper on a small area near [0; 0], but trajectory was like a hyperbole x/1 so the stage had to fast horizontal speed before landing. I made rudders like F-9R has and separated aerodynamic and engine phases.
Now the stage looks like Falcon 9 with one Merlin-1D and does aerodynamic maneuvers to reach close as possible to x=0 and slowdown, then land by one short burn with throttling 50-100%. The vechicle usually land on legs with low vertical speed and angle ±5º even if it didn't reach land zone(up to ~250 m). But it often lose stability if try to land far from [0; 0].
I hope you like the video and my idea :}

This isn't a true spaceX rocket, it doesn't blow up unexpectedly for no apparent reason!

That's very impressive,eanayayo!
For some reason,it reminds me of this:
