How Does This Rocket Steer Itself? -- Active Control Rocket Avionics (Building DIAMOND-X Part 2)

[@dustin7845]

I bet people like you have a much larger impact on space exploration than you realize. Keep on innovating, teaching, and most importantly inspiring others. Edit: I somehow offended people with this comment. My statement still stands. I believe channels like these collectively have the potential to influence people into college or career choices that will ultimately lead to a larger impact on rocket development. I fail to see how the work here is only applicable to weapons systems, and it shocks me that I have to clarify that I don't believe that this man is single handedly revolutionizing the space industry with an amateur rocket from his bedroom.

Good shit bro, this stuff is like a better version of what Joe Barnard was doing a couple years ago. That board is beautiful! There's a guy on the rocketry forum that cuts holes in the bottom of his body tubes to add to the base drag, his rockets fly stable with no fins and no active control, but they are inefficient due to the high drag. Rockets like that are really fun especially since the FAA waivers are low where I live, so I want to get into active control to spice things up. This is not a tutorial, contrary to what everyone yapping in the comments thinks, but it is a good resource with lots of good ideas that will simplify the engineering design process for people like me who would otherwise have to build the know-how from scratch. You could have kept your solutions a secret, but you shared it with everyone, thus making this part of the hobby slightly easier to get into. Thanks!

i have always wanted to become an electronics engineer or aeronautical engineer but i was not smart enough , damn your work is so impresive . Alot of respect

[@BasedF-15Pilot]

Good job. +1 subscriber. I will say based on what I know of supersonic flight transitions, if you ever intend to make this project supersonic, the proximity of the long fixed body fins to the articulating fins in back may prevent the articulating fins from 'grabbing' much air for maneuvering as the shock cones from the body fins will create 4 localized regions of low pressure around all of the movable surfaces because all 8 fins directly aligned fore and aft. Using grid fins in the back would fix this at the cost of subsonic efficiency, or maybe moving the body fins more forward on the rocket body. I wouldn't suggest rotating the body fins to be off axis because this would increase the drag and would put the back fins in line with shock cone paths, but this option might be better for subsonic only maneuvering. Look forward to seeing more of your videos. 👍

[@codetech5598]

_"if you ever intend to make this project supersonic"_ your name will be on the list for sure.

[@laytonmiller5865]

What about the articulating fins seamlessly connecting with the fixed ones such that when aligned with the main body axis (z axis?) it forms one seamless fin (or negligible gap between them)? Would the low-pressure pockets still have an impact in that case? I don't know much about airflow dynamics but it seems like its probably a low pressure "cone" so as you get closer to the source you'd have to articulate less to eliminate the offset? Just curious.

[@stockfotoman2123]

lockheed martin here, we would like our engineer back please

[@sebdapleb1523]

@@laytonmiller5865 In my mindsim (thinking about it for 3 seconds), the closeness to the source of the sonic boom would hurt the controls, not help. It could go either way I guess, but the turbulence coming from the fin's leading edge would probably get more manageable the farther away from the leading edge you go. I think that either way, active controlled fins for supersonic flights is a bad idea. The single point of contact would have to be very strong, adding weight and drag. Then again, we do it for fun so who cares about performance.

[@qinarizonaful]

That's why you distort the rocket body as the control surface in supersonic flight! Requires proper Reynold's numbers modeling in a wind tunnel. Just 2 cents. Think of "Flight of the Navigator", 1986. Party On!!!🎉🎉🎉❤🎉🎉🎉

[@judet2992]

Fun fact: you can’t send guidance data of any sort to the rocket in flight because that suddenly turns it into a guided missile. The FAA isn’t too happy about that. Edit: there's a difference between an internal guidance system for maneuvers made for the rocket, by the rocket, and externally choosing its direction from a controller. Missiles don't need a warhead to be a missile, and they can be tiny. Plus a supersonic dart does a lot more damage than a drone on Ebay which is why these are all legal, minus the missile aspect.

[@einhalbesbrot]

Is that true? So the FAA rather has uncontrolled probably malfuntioning aircrafts in the air? I mean a RC Plane can be controlled, or are there other restrictions that apply?

[@judet2992]

@@einhalbesbrot RC vehicles are different than what are essentially recoverable missiles. The internal guidance of the rocket can work, but any active external commands are NOT a good idea. You could use a tiny model rocket to hit something flying 5000’ up easily, and if you made it bigger and guided it (like a lot of later steps in the hobby), you could hit things at 20000’ or up.

So sweet man this is excellent work. So cool. why not multiplex your signal lines ex: single wire PPM for your multiple pwm channels. Or better i2c (wire.h), address different stages/sections with a small microcontroller slave, connected to corresponding actuators. all receiving data from a single i2c bus from the master avionics stack. This way you don’t really need more than 4 wires in the raceway.

[@conorstewart2214]

If he doesn’t need to receive data back from the lower modules then just using uart and only using the TX line on the main controller would work, just connect it to the RX line of the slave microcontrollers since they can all receive without interfering with each other, just start the data packet with an address. Then you only need three wires.

Have you explored using Rollerons, such as the Sidewinder missles use? It was revolutionary when guided missiles were coming into use.

[@ww-pw6di]

Could maybe even use a thin/slim servo as the rolleron body and save space inside?

[@ddegn]

The rollerons used in sidewinder missiles need to be spun up in order to work correctly. Sidewinders are launched while already in motion so the rollerons have been spun up prior to launch. I'm pretty sure there's a minimum airspeed required when launching a sidewinder since it the missile needs the speed to spin up the rollerons. A sidewinder launched from zero airspeed loses the benefit the rollerons would normally provide. Digital IMU technology has come far enough that it makes more sense to use the digital sensors. I personally think rollerons are super cool. I just don't think they're appropriate for this application.

[@sorryociffer]

@@ddegn The MIM-72 Chapparal was a SAM that used Sidewinder missiles and entered service in 1969 and phased out in 1998. I think the initial launch, because it won’t have to do crazy off bore-sight maneuvers, would give them the spin up needed.

[@LafayetteSystems]

Rollerons solved the roll instability problems the early missiles had with canards. I have built canard controlled rockets in the past (without rollerons) and had similar issues. This rocket uses aft fin control, so I have to worry less about roll reversal and changes to the roll control dynamics throughout flight. Other folks like Jim Jarvis use canards, but let their entire aft fin assembly spin freely about the rocket's long axis to solve the problem. Spinning fin cans seems to work well, and are used on a number of missiles like GMLRS and the Excalibur guided artillery ammunition.

The missile knows where it is at all times. It knows this because it knows where it isn't, by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation. The guidance sub-system uses deviations to generate corrective commands to drive the missile from a position where it is, to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position where it was, is now the position that it isn't. In the event of the position that it is in is not the position that it wasn't, the system has required a variation. The variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computance scenario works as follows: Because a variation has modified some of the information the missile has obtained, it is not sure just where it is, however it is sure where it isn't, within reason, and it knows where it was. It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum og where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "air"
